The present invention relates to agrochemical compositions which comprise certain alcohol alkoxylates of the amphiphilic type, and the use of the alcohol alkoxylates as activity-improving adjuvant in the agrochemical sector, and in particular in the plant protection sector.
Besides the optimization of the active ingredient properties, the development of an effective agent is of particular importance with regard to the industrial production and application of active ingredients. By formulating the active ingredient(s) correctly, an optimal balance must be found between properties, some of which are in conflict with each other, such as the biological activity, the toxicology, potential environmental effects, and the costs. Moreover, the formulation is a decisive factor in determining the shelf life and the user friendliness of a composition.
An efficient uptake of the active ingredient by the plant is of particular importance for the activity of an agrochemical composition. If this uptake is via the leaf, it constitutes a complex translocation process, where the active substance, for example a herbicide, must first penetrate the waxy cuticula of the leaf and subsequently diffuse, via the cuticula, into the tissue underneath, to the actual site of action.
It is generally known and agricultural practice to add certain adjuvants to formulations in order to improve the activity of the latter. Advantageously, this allows the amounts of active ingredient in the formulation to be reduced while maintaining the same activity, thereby being able to minimize costs and, if appropriate, operating within existing legislation. In individual cases, this also allows the spectrum of the active ingredient to be widened, since plants whose treatment with a specific active ingredient without addition was only possible to an unsatisfactory extent, are now capable of being subjected to such a treatment as the result of the addition of certain auxiliaries. Furthermore, the performance under adverse environmental conditions may be increased in individual cases by a suitable formulation. Of course, incompatibilities of various active ingredients in one formulation can also be avoided.
Such auxiliaries are sometimes also referred to adjuvants. Frequently, they take the form of surface-active or salt-like compounds. Depending on their mode of action, one can distinguish between, for example, modifiers, actuators, fertilizers and pH buffers. Modifiers influence the wetting, adhesion and spreading of a formulation. Actuators break the waxy plant cuticula and improve the penetration of the active ingredient into the cuticula, both in the short term (within minutes) and in the long term (within hours). Fertilizers such as ammonium sulfate, ammonium nitrate or urea improve the absorption and solubility of the active ingredient, and they may reduce antagonistic patterns of behavior of active ingredients. pH buffers are traditionally used for optimally adjusting the pH of the formulation.
As regards the uptake of the active ingredient into the leaf, surface-active substances may act as modifiers and actuators. In general, it is assumed that suitable surface-active substances are capable of increasing the effective contact area of fluids on leaves by reducing the surface tension. Moreover, certain surface-active substances are capable of dissolving or disrupting the epicuticular waxes, which facilitates the absorption of the active ingredient. Furthermore, some surface-active substances are also capable of improving the solubility of active ingredients in formulations, thereby avoiding, or at least delaying, crystal formation. Finally, in certain cases they can also influence the absorption of active ingredients by retaining moisture.
Adjuvants of the surface-active type are exploited in many ways for agrochemical purposes. They can be divided into anionic, cationic, nonionic or amphoteric groups of substances.
Petrol-based oils have traditionally been used as activating adjuvants. In recent times, seed extracts, natural oils and their derivatives, for example, from soybeans, sunflowers and coconut, have also been employed.
The synthetic surface-active substances which have usually been used as actuators take the form of, inter alia, polyoxyethylene condensates with alcohols, alkylphenols or alkylamines with HLB values in the range of from 8 to 13. In this regard, the document WO 00/42847 mentions for example the use of certain linear alcohol alkoxylates in order to increase the activity of agrochemical biocide formulations. WO 03/090531 describes the use of alkoxylates of certain branched alcohols, among which in particular 2-propylheptanol, C13-oxoalcohols and C10-oxoalcohols, as adjuvant for the agrochemical sector. Similar alcohol alkoxylates have been proposed in WO 2005/015998 specifically as adjuvants for fungicidal benzamide oxime derivatives. WO 00/35278 relates to agrochemical formulations based on PO/EO block copolymers of 2-ethylhexanol.
However, the spectrum of alcohol alkoxylates is varied. As surfactants, they are predominantly used in detergents and cleaners, in the metal-working industry, in the production and processing of textiles, in the leather industry, in papermaking, in the printing, electroplating and photographic industries, in water treatment, in pharmaceutical, veterinary and plant protection formulations, or in the plastics manufacturing and processing industries.
EP-A 1 078 946 describes block copolymeric, styrene-oxide-containing polyalkylene oxides of straight-chain or branched or cycloaliphatic alcohols having 8 to 13 carbon atoms and their use as low-foam pigment wetters in aqueous pigment pastes, aqueous and low-solvent varnishes and inks. Similar styrene-oxide-containing block copolymers are described in EP-A 1 403 324 as viscosity regulators in thickeners for paints and varnishes. The same block copolymeric, styrene-oxide-containing polyalkylene oxides are proposed in accordance with WO-A 2006/097378 in combination with ketone/aldehyde resins as dispersants, both for solvent-free, solvent-containing and aqueous universal pigment preparations (see also WO-A 2006/097379).
Further styrene-oxide-containing copolymers and their use as emulsifiers and dispersants in the field of the pigment and bitumen dispersions and in emulsion polymerization are described in DE-A 102 52 452.
EP-A 403 718 relates to styrene-oxide-containing polyalkylene oxides of alcohols having 1 to 24 carbon atoms and to their use as textile-finishing agents, in particular as emulsifiers, dyeing adjuvants, wetters, deaerators or padding agents.
JP-A 03206001 describes styrene oxide adducts of polyethylene glycols and polypropylene glycols with weight-average molecular weights of 20000 g/mol and more and their use as emulsifiers in insecticide-containing aqueous emulsions. WO-A 2006/002984 proposes to employ nonionic block copolymers in liquid concentrates of pesticides as emulsifiers. The nonionic block copolymers essentially take the form of EO/PO tri-block copolymers. This publication furthermore mentions block copolymers of the formulae R1-PEO-O-PAO-R2 or R1-PAO-O-PEO-H, where R1 is C1-C20-alkyl or C1-C20-alkylphenyl, R2 is hydrogen, C1-C8-alkyl, C1-C8-alkylcarbonyl or benzyl, PEO is a polyethylene oxide unit, and PAO is a hydrophobic polyether unit derived from C1-C10-alkylene oxides such as propylene oxide, 1,2-butylene oxide, cis- or trans-2,3-butylene oxide or isobutylene oxide, 1,2-pentene oxide; 1,2-hexene oxide, 1,2-decene oxide or styrene oxide, preferably from C3-C4-alkylene oxides.
It is in particular the structures of the alcohol moiety and in certain cases also those of the alkoxylate moiety which influence the properties of the alkoxylates so that a variety of technical effects come in useful in the abovementioned applications. These include wetting, spreading, penetration, adhesion, film formation, the improvement of compatibilities, drift control, and defoaming.
The present invention is based on the object of providing further adjuvants which are useful in the agrochemical sector.
This object is achieved by the present invention by the use of styrene-oxide-containing alcohol alkoxylates as adjuvant and by the provision of agrochemical compositions which comprise these alkoxylates.

(b) at least one alkoxylated alcohol of the formula (I)

where at least one of x or z is greater than 0.
The alcohol alkoxylates which are present in the compositions according to the invention have adjuvant, in particular activity-enhancing, properties. Thus, the addition of such alkoxylates makes possible a faster uptake of active ingredients by a plant to be treated with the active ingredient. The adjuvant activity gives rise in particular to the following aspects in the treatment of plants with one or more active ingredients:
Accordingly, the present invention also relates to the use of an alkoxylated alcohol of the formula (I)
R—O—(CpH2pO)q-[(CnH2nO)x—(PhC2H3O)y—(CmH2mO)z]co-Z (I)
in which
R represents an aliphatic or aromatic radical having 1 to 30 carbon atoms;
p represents 2 or 3;
q represents 0, 1, 2 or 3;
n, m independently of one another represent an integer from 2 to 16;
x represents a value of from 0 to 100;
y represents a value of from 0.5 to 100;
z represents a value of from 0 to 100;
x+y+z corresponds to a value of from 2 to 100, and
Z represents hydrogen or an end cap,
where at least one of x or z is greater than 0
as adjuvant in the treatment of plants.
The use according to the invention is directed in particular to plant cultivation, to agriculture and to horticulture. In particular, it serves for controlling undesired plant growth.

Moreover, the alkoxylates to be used in accordance with the invention can also be used in crops which tolerate the action of pesticides, in particular of herbicides. Such crops can be obtained for example by breeding, but also by recombinant methods.
Some of the alkoxylates according to the invention are known per se. For example, the publications EP-A 1 078 946, EP-A 1 403 324, WO-A 2006097378, WO-A 2006097379, DE-A 102 52 452 and EP-A 403 718 which have been mentioned at the outset describe suitable alkoxylates. The description of these alkoxylates in these publications is herewith expressly referred to, and the alkoxylates themselves, and also their preparation, disclosed therein are thereby incorporated into the present disclosure by reference.
The alcohol moiety of the alcohol alkoxylates to be used in accordance with the invention is, as a rule, based on alcohols or alcohol mixtures having 1 to 30 carbon atoms, which alcohols or alcohol mixtures are known per se. They include firstly short-chain alcohols or alcohol mixtures having 1 to 7 and in particular either 1 to 4 or 5 to 7 carbon atoms, and secondly long-chain alcohols or alcohol mixtures having 8 to 30, preferably 8 to 20, and in particular 9 to 15 carbon atoms. They are expediently monofunctional alcohols.
In formula (I), R represents the aliphatic or aromatic radical of an alcohol R—OH which may be employed as starter alcohol in the preparation of the alcohol alkoxylates. R preferably represents C1-C30-alkyl or C1-C30-alkenyl.
In the event that the alcohol is a short-chain aliphatic alcohol, R in formula (I) represents in particular short-chain alkyl, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, 2-butyl, isobutyl or tert-butyl, n-pentyl, 1-methylbutyl, 2-methylbutyl, 3-methyl-butyl, 1,1-dimethylpropyl, 1,2-dimethylpropyl, 2,2-dimethylpropyl, 1-ethylpropyl, 2-ethylpropyl, n-hexyl, 1-methylpentyl, 2-methylpentyl, 3-methylpentyl, 4-methylpentyl, 1,1-dimethylbutyl, 1,2-dimethylbutyl, 1,3-dimethylbutyl, 2,2-dimethylbutyl, 2,3-dimethyl-butyl, 3,3-dimethylbutyl, 1-ethylbutyl, 2-ethylbutyl, 3-ethylbutyl, 1,1,2-trimethylpropyl, 1,2,2-trimethylpropyl, 1-ethyl-1-methylpropyl, 1-ethyl-2-methylpropyl, 2-ethyl-1-methyl-propyl, 2-ethyl-2-methylpropyl, n-heptyl, 1-methylhexyl, 2-methylhexyl, 3-methylhexyl, 4-methylhexyl, 5-methylhexyl, 1,1-dimethylpentyl, 1,2-dimethylpentyl, 1,3-dimethyl-pentyl, 1,4-dimethylpentyl, 2,2-dimethylpentyl, 2,3-dimethylpentyl, 2,4-dimethylpentyl, 3,3-dimethylpentyl, 3,4-dimethylpentyl, 4,4-dimethylpentyl, 1-ethylpentyl, 2-ethylpentyl, 3-ethylpentyl, 4-ethylpentyl, 1,1,2-trimethylbutyl, 1,1,3-trimethylbutyl, 1,2,2-trimethyl-butyl, 1,2,3-trimethylbutyl, 1,3,3-trimethylbutyl, 1-ethyl-1-methylbutyl, 1-ethyl-2-methyl-butyl, 1-ethyl-3-methylbutyl, 2-ethyl-1-methylbutyl, 2-ethyl-2-methylbutyl, 2-ethyl-3-methylbutyl, 3-ethyl-1-methylbutyl, 3-ethyl-2-methylbutyl, 3-ethyl-3-methyl-butyl, 1-propylbutyl, 2-propylbutyl, 3-propylbutyl, 1-butylpropyl, 2-butylpropyl, 1-propyl-1-methylpropyl, 1-propyl-2-methylpropyl, 2-propyl-1-methylpropyl, 2-propyl-2-methylpropyl, 1,1-diethylpropyl, 1,2-diethylpropyl or 2,1-diethylpropyl, it also being possible for mixtures of two or more alcohol alkoxylates in which R is different to be suitable.
In the event that the alcohol is a long-chain aliphatic alcohol, R in formula (I) represents in particular long-chain alkyl such as octanyl, 2-ethylhexanyl, nonanyl, decanyl, undecanyl, dodecanyl, 2-butyloctanyl, tridecanyl, tetradecanyl, pentadecanyl, isooctanyl, isononanyl, isodecanyl, iso-undecanyl, isododecanyl, isotridecanyl, isotetradecanyl, isopentadecanyl, 2-propylheptanyl, hexadecanyl, heptadecanyl, octadecanyl, it also being possible for mixtures of two or more alcohol alkoxylates in which R is different to be suitable.
In the event that the alcohol is a cycloaliphatic or aromatic alcohol, R in formula (I) represents in particular cyclohexanyl, phenyl, cresyl isomers, isobutylphenyl, isobutylcresyl, diisobutylphenyl, diisobutylcresyl, tert-butylphenyl, tert-butylcresyl, di-tert-butylphenyl, di-tert-butylcresyl, isooctylphenyl, diisooctylphenyl, isononylphenyl, diisononylphenyl, isododecylphenyl, diisododecylphenyl, naphthyl, anthracenyl, it also being possible for mixtures of two or more alcohol alkoxylates in which the R is different to be suitable.
The alcohol moiety of the alkoxylates to be used may be straight-chain (linear), branched or cyclic. In the event that it is branched, the main chain of the alcohol moiety, according to a particular embodiment, has, as a rule, 1 to 4 branches, it also being possible to use alcohols with a higher or lower degree of branching in admixture with other alcohol alkoxylates, as long as the mean number of branches in the mixture is within the stated range.
In general, the branches independently of one another have 1 to 10, preferably 1 to 6 and in particular 1 to 4 carbon atoms. Particular branches are methyl, ethyl, n-propyl or isopropyl groups.
The linear short-chain alcohols include in particular methanol, ethanol, n-propanol, n-butanol, n-pentanol and n-hexanol, furthermore n-heptanol.
The linear long-chain alcohols include, in particular, octadecanol (stearyl alcohol). Among the branched long-chain alcohols, 2-ethylhexanol and 2-propylheptanol must be mentioned in particular. In addition, isodecanol and isotridecanol are of importance.
The abovementioned alcohols having 8 or 10 carbon atoms, in particular the branched ones, such as isodecanol and Isotridecanol having a degree of branching in the range from 1 to 4, are particularly advantageous.
In accordance with a particular embodiment, the alkoxylated alcohol is selected among alkoxylated alcohols of the formula (I) where q represents zero.
In accordance with a particular embodiment, the alkoxylated alcohol is selected among alkoxylated alcohols of the formula (I) where q represents 1, 2 or 3. Such alcohol alkoxylates can be prepared in a targeted fashion by reacting for example a compound of the formula (III)
R—O—(CpH2pO)q—H (III)
where
R, p and q are as defined herein first with styrene oxide and alkylene oxide.
The compounds of the formula (III) are, in particular, mono-C1-C7-alkyl ethers of ethylene glycol (p=2; q=1), propylene glycol (p=3; q=1), diethylene glycol (p=2; q=2), dipropylene glycol (p=3; q=2), triethylene glycol (p=2; q=3) or tripropylene glycol (p=3; q=3), which are known per se.
Of particular importance in accordance with in the invention are the alkyl ethers of mono-, di- and tripropylene glycol of the formula (IIIa)
R—O—(CH2CH(CH3)O)q—H (IIIa)
where R represents C1-C7-alkyl and q is as defined herein.
Another aspect emphasizes the mono-C1-C4-alkyl ethers (i.e. R represents in particular C1-C4-alkyl), and of these especially the dipropylene glycol monoalkyl ethers (q=2). They include, in particular, dipropylene glycol monomethyl ether, dipropylene glycol monoethyl ether, dipropylene glycol mono-n-propyl ether and dipropylene glycol mono-n-butyl ether.
Suitable alcohols and in particular fatty alcohols are obtainable not only from native sources, for example by obtaining and, if required or desired, by hydrolyzing, transesterifying and/or hydrogenating, glycerides and fatty acids, but also via the synthetic route, for example synthesis from starting materials with a lower number of carbon atoms. Thus, for example the SHOP process (Shell Higher Olefin Process) gives, starting from ethene, olefin fractions with a carbon number which is suitable for processing into surfactants. The functionalization of the olefins to give the corresponding alcohols is performed here for example by hydroformylation and hydrogenation.
Olefins with a carbon number suitable for processing into suitable alcohols can also be obtained by oligomerizing C3-C6-alkenes such as, in particular, propene or butene, or mixtures of these.
Lower olefins can furthermore be oligomerized by means of heterogeneous acidic catalysts, for example supported phosphoric acid, and subsequently functionalized to give alcohols.
A general possibility for the synthesis of branched alcohols is, for example, the reaction of aldehydes or ketones with Grignard reagents (Grignard synthesis). It is also possible to employ, instead of Grignard reagents, aryl-lithium compounds or alkyl-lithium compounds, which are distinguished by a higher reactivity. Furthermore, the branched alcohols can be obtained by aldol condensation, the reaction conditions being known to the skilled worker.
The alkoxylation is the result of the reaction with styrene oxide and suitable alkylene oxides which, as a result, have 2 to 16 and preferably 2 to 6 carbon atoms. The following may be mentioned in particular in this context: ethylene oxide (EO), 1,2-propylene oxide (PO), 1,2-butylene oxide (BO), 1,2-pentylene oxide (PeO) and 1,2-hexylene oxide (HO). Furthermore, decylene oxide (DeO) must also be mentioned. Particularly preferred are ethylene oxide (EO) and 1,2-propylene oxide (PO). Accordingly, alcohol alkoxylates of the formula (I) or specific embodiments thereof in which n and m independently of one another represent 2 or 3, for example n represents 2 and m represents 3, n represents 3 and m represents 2, or n and m represent 2, must be mentioned in particular in accordance with the invention.
The respective degree of alkoxylation is the result of the charged amounts of alkylene oxide(s) and the reaction conditions selected for the reaction. The former is, as a rule, a statistical mean, since the number of styrene oxide and alkylene oxide units of the alcohol alkoxylates which are the result of the reaction varies.
The degree of alkoxylation, i.e. the mean chain length of the polyether chains of alcohol alkoxylates according to the invention and their composition (in other words, the values of x, y, z) can be controlled by the ratio of the molar amounts of alcohol to styrene oxide and alkylene oxide employed in their preparation, and by the reaction conditions. Preferred alcohol alkoxylates are those which have at least approximately 2, preferably at least approximately 4, in particular at least approximately 5, especially at least approximately 6, 7 or 8 and particularly preferably at least approximately 10 styrene oxide and alkylene oxide units (x+y+z). In accordance with a further aspect, alcohol alkoxylates having up to about 100, preferably having up to about 80, in particular having up to about 60, especially having up to about 40 and particularly preferably having up to about 30 styrene oxide and alkylene oxide units (x+y+z) may be mentioned. If x=zero, alcohol alkoxylates having at least approximately 2, preferably at least approximately 4, in particular at least approximately 5, especially at least approximately 6, 7 or 8 and particularly preferably having at least approximately 10 styrene oxide and alkylene oxide units (y+z) are preferred, and in accordance with a further aspect the alcohol alkoxylates have up to about 100, preferably up to about 80, in particular up to about 60, especially up to about 40 and particularly preferably up to about 30 styrene oxide and alkylene oxide units (y+z). If z=zero, alcohol alkoxylates having at least approximately 2, preferably at least approximately 4, in particular at least approximately 5, especially at least approximately 6, 7 or 8 and particularly preferably having at least approximately 10 styrene oxide and alkylene oxide units (y+x) are preferred, and in accordance with a further aspect the alcohol alkoxylates have up to about 100, preferably up to about 80, in particular up to about 60, especially up to about 40 and particularly preferably up to about 30 styrene oxide and alkylene oxide units (y+x). Thus, the degree f alkoxylation (sum of x, y and z, of y and z, or of x and y) is preferably in the range from about 2 to 100, about 4 to 80, about 5 to 60, about 6, 7 or 8 to 40, or about 10 to 30.
In accordance with a particular embodiment, the alcohol alkoxylates of the formula (I) used are those in which the value of x, the value of z or the total of x and z is greater than the value of y. These are alcohol alkoxylates which comprise more alkylene oxide units than styrene oxide units.
Preferred alkoxylates in this context are those in which the ratio of alkylene oxide to styrene oxide (z to y; x to y; or (x+z) to y) is at least 1.1:1, preferably at least 1.5:1, in particular at least 2:1, especially at least 5:1 and particularly preferably at least 10:1. In accordance with a further aspect, there must be mentioned alkoxylates in which the ratio of alkylene oxide to styrene oxide (z to y; x to y; or (x+z) to y) is up to 25:1, preferably up to 20:1 and in particular up to 15:1.
According to one aspect, the degree of alkoxylation to be attributed to the styrene oxide units (value of y) is, as a rule, at least approximately 0.5, preferably at least approximately 0.9 and in particular at least approximately 1. In accordance with another aspect, the degree of alkoxylation to be attributed to the styrene oxide units (value of y) is, as a rule, not more than approximately 30, preferably not more than approximately 20 and in particular not more than 15. Specific alcohol alkoxylates of the invention have less than about 3, especially less than about 2.5 and in particular less than about 2 styrene oxide units per molecule, so that the degree of alkoxylation assigned to the styrene oxide units (value of y) is, as a rule, in the range of from about 0.5 to 2.5, preferably in the range of from about 0.9 to 2 and in particular in the range of from about 1 to 1.5. Of these, alcohol alkoxylates whose degree of alkoxylation to be attributed to the styrene oxide units (value of y) is in the range of from about 0.5 to 0.9 are of particularly special embodiment.
The degree of alkoxylation to be attributed to the alkylene oxide units (value of x, z or (x+z)) is, as a rule, at least approximately 1, preferably at least approximately 3 and in particular at least approximately 5. In accordance with another aspect, the degree of alkoxylation to be attributed to the alkylene oxide units (value of x, z or (x+z)) is, as a rule, not more than approximately 50, preferably not more than approximately 30 and in particular not more than approximately 20.
A particular embodiment are alcohol alkoxylates of the formula (I) where z is zero, i.e. alkoxylated alcohols of the formula (Ia)
R—O—(CpH2pO)q-[(CnH2nO)x-(PhC2H3O)y]co-Z (Ia)
where R, p, q, n, x, y, Z are as defined above and x is greater than zero.
A further particular embodiment are alcohol alkoxylates of the formula (I), where x and z are greater than zero.
The reaction of the alcohols, or alcohol mixtures, with styrene oxide and the alkylene oxide(s) is carried out by customary methods known to the skilled worker, and in apparatuses conventionally used for this purpose.
The alkoxylation can be catalyzed by strong bases such as alkali metal hydroxides and alkaline-earth metal hydroxides, Brönsted acids or Lewis acids, such as AlCl3, BF3 and the like. Catalysts such as hydrotalcite or DMC may be used for alcohol alkoxylates with a narrow distribution.
The alkoxylation is preferably carried out at temperatures in the range of from approximately 80 to 250° C., preferably approximately 100 to 220° C. The pressure is preferably between ambient pressure and 600 bar. If desired, the styrene oxide and/or alkylene oxide may comprise an admixture of inert gas, for example of approximately 5 to 60%.
In formulae (I) and (Ia), the alkylene oxide and styrene oxide units, if present, can be arranged as desired. The structural unit [ . . . ]∞ can thus be a random copolymer, a gradient copolymer, an alternating copolymer or a block copolymer made up of alkylene oxide units CnH2nO, styrene oxide units PhC2H3O and/or alkylene oxide units CmH2mO.
In the event that n represents a value of from 3 to 16, —CnH2nO— is either —CH(Cn-2H2n-3)CH2O— (such as —CH(CH3)CH2O—) or —CH2CH(CHn-2H2n-3)O— (such as —CH2CH(CH3)O—). In this context, a particular alcohol alkoxylate may essentially comprise alkylene oxide units of one or the other type, or both. An alkylene oxide block —(CnH2nO)x— can be composed essentially of alkylene oxide units of the formula —CH2CH(Cn-2H2n-3)O—, essentially of alkylene oxide units of the formula —CH(Cn-2H2n-3)CH2O—, or of both alkylene oxide units of the formula —CH2CH(Cn-2H2n-3)O— and of alkylene oxide units of the formula —CH(Cn-2H2n-3)CH2O—, where, in the latter case, the two alkylene oxide units may be randomly distributed, alternating or arranged as two or more sub-blocks. In the case of base-catalyzed alkoxylation, the result is predominantly alkylene oxide units of the formula —CH2CH(Cn-2H2n-3)O—, since the attack of the anion preferably takes place at the secondary carbon atom of the propylene oxide, which is less sterically hindered. Customary molar ratios are those of more than 60:40, 70:30 or 80:20, for example approximately 85:15, in favor of alkylene oxide units of the formula —CH2CH(Cn-2H2n-3)O—. This also applies analogously to —CmH2mO— in the event that m represents a value of from 3 to 16.
PhC2H3O represents a styrene oxide unit of the formulae:
In this context, a certain alcohol alkoxylate may essentially comprise styrene oxide units of one or the other type, or both. The same applies to styrene oxide blocks, where, again, the two styrene oxide units may be randomly distributed, alternating or arranged as two or more sub-blocks. In the case of base-catalyzed alkoxylation, the result is predominantly alkylene oxide units of the formula —CH2CH(Ph)O—, since the attack of the anion preferably takes place at the secondary carbon atom of the styrene oxide, which is less sterically hindered. Customary molar ratios are those of more than 60:40, 70:30 or 80:20, for example approximately 85:15, in favor of alkylene oxide units of the formula —CH2CH(Ph)O—.
In accordance with a particular embodiment, the alkoxylated alcohol is selected among alcohol block alkoxylates of the formula (II)
R—O—(CpH2pO)q—(CnH2nO)x—(PhC2H3O)y—(CmH2mO)zZ (II)
where R, p, q, n, m, x, y, z, Z are as defined herein.
A further particular embodiment are alcohol alkoxylates of the formula (II), where x and z are greater than zero.
The alcohol block alkoxylates of the formula (II) include, in particular, alkoxylated alcohols of the formula (IIa)
R—O—(CpH2pO)q-(PhC2H3O)y—(CmH2mO)z—Z (IIa),

One type of alcohol alkoxylates to be employed is based on styrene oxide and one type of alkylene oxide.
Another type of alcohol alkoxylates to be employed is based on styrene oxide and two different types of alkylene oxide.
In accordance with one aspect, it is preferred that the alcohol alkoxylates according to the invention are ethoxylated, or have at least one ethylene oxide block.
In accordance with a particular embodiment, the alcohol alkoxylates used, of the formula (I), (Ia), (II) or (IIb), are those in which n=2 and x is greater than zero. These take the form of alcohol alkoxylates of the EO/styrene oxide type, which includes especially those which have styrene oxide and ethylene oxide units (n=2; x>zero; z=zero, that is in particular alcohol alkoxylates of the formula (Ia)), and those which, besides styrene oxide and ethylene oxide units, also comprise units of another type of alkylene oxide (n=2; x>zero; z>zero). Among the alcohol alkoxylates of the EO/styrene oxide type, there must be mentioned especially block alkoxylates of the formula (II), which include in particular those which have a styrene oxide block and an ethylene oxide block (n=2; x>zero; z=zero, or x=zero; m=2; z>zero), those which, beside a styrene oxide block and an ethylene oxide block, comprise a further ethylene oxide block (n=2; x>zero; z>zero; m=2; z>zero), and those which, besides a styrene oxide block and an ethylene oxide block, also comprise a block of another type of alkylene oxide (n=2; x>zero; z>zero, m>2, or x>zero; n>2, m=2; z>zero). The alcohol alkoxylates with a styrene oxide block and an ethylene oxide block include in particular those of the formula (II) with a styrene oxide block bonded to the alcohol moiety (x=zero; m=2; z>zero, that is, in particular, alcohol alkoxylates of the formula (IIa)), and those of the formula (II) with an ethylene oxide block bonded to the alcohol moiety (n=2; x>zero; z=zero, that is, in particular, alcohol alkoxylates of the formula (IIb)). The alcohol alkoxylates with a styrene oxide block, an ethylene oxide block and a block of a further type of alkylene oxide include in particular those of the formula (II) with a propylene oxide block bonded to the alcohol moiety and a terminal EO block (n=3; x>zero; m=2; z>zero).
A particular embodiment are alcohol alkoxylates according to the invention which are not end-capped (Z=H).
In accordance with a further preferred embodiment, the alcohol alkoxylates according to the invention are end-capped. In this case, Z preferably represents C1-C4-alkyl, more preferably C1-C3-alkyl and in particular methyl. Other radicals which are furthermore suitable for Z are C2-C4-alkenyl (for example allyl), C6-C10-aryl (for example phenyl) or C6-C10-aryl-C1-C2-alkyl (for example benzyl), C1-C4-alkylcarbonyl (for example acetyl, propionyl, butyryl), C6-C10-arylcarbonyl (for example benzoyl). Tertiary alcohol residues such as 2-hydroxyisobutyl or inorganic acid groups, in particular phosphate, diphosphate or sulfate, are also suitable.
End-capped alcohol alkoxylates can be prepared in a manner known per se by reacting the non-end-capped alcohol alkoxylate with suitable reagents, for example dialkyl sulfates. Such reactions are described for example in EP-A 0 302 487 and EP-A 0 161 537, whose disclosure is herewith incorporated in its entirety by reference.
The theoretical molecular weight of alcohol alkoxylates which are suitable in accordance with the invention is, as a rule, less than 5000 g/mol. Preferred are alcohol alkoxylates with a molecular weight of less than 4000 g/mol, less than 3000 g/mol, or less than 2500 g/mol. In accordance with a particular embodiment, the molecular weight is less than 1000 g/mol.
The weight-average molecular weight of alcohol alkoxylates which are suitable in accordance with the invention is, as a rule, less than 5000 g/mol. Preferred are alcohol alkoxylates with a molecular weight of less than 4500 g/mol, less than 4000 g/mol, or less than 3500 g/mol. In accordance with a particular embodiment, the molecular weight is less than 3000 g/mol. The weight-average molecular weight data relate to the determination by means of gel permeation chromatography as described in the examples section and used for the alkoxylates disclosed in the reference examples.
The term “degree of branching” of R is defined herein in a manner known per se for the number of methyl groups in R minus 1. The same applies to Z by analogy. The degree of branching of the alkoxylate moiety results from the degree of alkoxylation and the alkylene oxides involved in the alkoxylation. The medium degree of branching is the average statistical value of the degrees of branching of all molecules of a sample.
The medium degree of branching can be determined by 1H-NMR spectroscopically for primary and secondary alcohols as follows. For this purpose a sample of the alcohol is initially submitted to a derivatisation with trichloroacetyl isocyanate (TAI). Thereby the alcohols are converted into the esters of carbamic acid. The signals of the esterified primary alcohols are in the range of =4.7 to 4.0 ppm, those of the esterified secondary alcohols are at about 5 ppm and water present in the sample reacts with TAI to form carbamic acid. All methyl, methylene and methine groups are in the range from 2.4 to 0.4 ppm. Thereby the signals <1 ppm are assigned to methyl groups. From the resulting spectrum the medium degree of branching (ISO index) is calculated as follows:
Iso-Index=((F(CH3)/3)/(F(CH2—OH)/2+F(CHR—OH)))−1
wherein F(CH3) stands for the signal area corresponding to the methyl protons, F(CH2—OH) for the signal area of the methylene protons in the CH2—OH group, and F(CHR—OH) for the signal area of the methine protons of the CHR—OH group.
Amounts of component (b), i.e. of alcohol alkoxylate, on the total weight of the mean of more than 1% by weight, preferably of more than 5% by weight and in particular of more than 10% by weight, are advantageous. On the other hand, amounts of component (b) on the total weight of the mean of less than 50% by weight, preferably of less than 45% by weight and in particular of less than 40% by weight, are, as a rule, expedient.
The plant treatment active ingredient of component (a) can mean any substance whose purpose or effect it is to prevent the attack of any pest on a plant, or to safeguard against, repel or destroy the pest, or to reduce the damage caused by it in any other manner (pesticide). As has been stated at the outset, plant pests may belong to different groups of organisms; among the higher animals, a large number of important pests can be found in particular among the insects and mites, furthermore among nematodes and slugs and snails; vertebrates such as mammals and birds are of lesser importance in today's industrialized countries.

It is also possible to employ salts, in particular agriculturally useful salts, of the active ingredients mentioned specifically in this context.
In a particular embodiment of the invention, the plant protection agent is a fungicide.
It is especially preferred in this context that the fungicide is an active ingredient selected from the group of the anilides, triazolopyrimidines, strobilurins or triazoles, in particular an anilide selected among boscalid, carboxin, metalaxyl and oxadixyl, the triazolopyrimidine 5-chloro-7-(4-methylpiperidin-1-yl)-6-(2,4,6-trifluorophenyl)-[1,2,4]triazol[1,5-a]-pyrimidine, a strobilurin selected among azoxystrobin, pyraclostrobin, dimoxystrobin, trifloxystrobin, fluoxystrobin, picoxystrobin and orysastrobin, or a triazole selected among epoxiconazole, metconazole, tebuconazole, flusilazol, fluquinconazole, triticonazole, propiconazole, penconazole, cyproconazole and prothioconazole.

Stereoisomers, such as enantiomers or diastereoisomers of the formulae, must be mentioned in particular. In addition to the essentially pure isomers, the compounds of the formulae also include their isomer mixtures, for example stereoisomer mixtures.
Active ingredients with a higher content of the stereoisomer which is biologically more active than the optical antipode, especially preferably isomerically pure active ingredients, are generally preferred.
The present invention particularly relates to compositions with high active-ingredient contents (concentrates). Thus, component (a) will, as a rule, amount to more than 5% by weight, preferably more than 10% by weight and in particular more than 20% by weight of the total weight of the composition. On the other hand, component (a) will expediently amount, as a rule, to less than 80% by weight, preferably less than 70% by weight and in particular less than 60% by weight of the total weight of the composition.
In order to ensure sufficient adjuvant effect, the weight ratio of component (b) to component (a) is preferably more than 0.5, in particular more than 1 and advantageously more than 2.
Furthermore, the compositions according to the invention may comprise auxiliaries and/or additives which are customary for the preparation of formulations in the agrochemical sector, and in particular in the crop protection sector. These include, for example, surfactants, dispersants, wetters, thickeners, organic solvents, cosolvents, antifoams, carboxylic acids, preservatives, stabilizers and the like.
In accordance with a particular embodiment of the present invention, the compositions comprise, as surface-active component (c), at least one (further) surfactant. In this context, the term “surfactant” refers to interface-active or surface-active agents.
Component (c) is added in particular as a dispersant or emulsifier, mainly to disperse a solid component in suspension concentrates. Component (c) may furthermore act in part as wetter.
Substances which are useful in principle are anionic, cationic, amphoteric and nonionic surfactants, with polymer surfactants and surfactants with heteroatoms in the hydrophobic group being included.

The nonionic surfactants include, for example, further alkoxylates and especially ethoxylates, and nonionic surfactants, in particular
The amphoteric surfactants include, for example, sulfobetains, carboxybetains and alkyldimethylamine oxides, for example tetradecyldimethylamine oxide.
The polymeric surfactants include, for example, di-, tri-, and multiblock polymers of the type (AB)x, ABA and BAB, e.g. if appropriate end-group-closed ethylene-oxide/propylene oxide block copolymers, e.g. ethylene diamine/EO/PO block copolymers, polystyrene/block/polyethylene oxide, and AB comb polymers, e.g. polymethacrylate/comb/polyethylene oxide.
Further surfactants to be mentioned by way of example in this context are perfluorine surfactants, silicone surfactants, for example polyether-modified siloxanes, phospholipids, such as, for example, lecithin or chemically modified lecithins, amino acid surfactants, for example N-lauroylglutamate, and surface-active homo- and copolymers, for example polyvinylpyrrolidone, polyacrylic acids in the form of their salts, polyvinyl alcohol, polypropylene oxide, polyethylene oxide, maleic anhydride/isobutene copolymers and vinylpyrrolidone/vinyl acetate copolymers.
Unless specified, the alkyl chains of the abovementioned surfactants are linear or branched radicals having, usually, 8 to 20 carbon atoms.

Component (c)—if present—will, as a rule, amount to less than 50% by weight, preferably less than 15% by weight and in particular less than 5% by weight of the total weight of the composition.
In accordance with a particular embodiment of the present invention, the compositions comprise, as component (d), at least one further auxiliary.
Component (d) may serve a multitude of purposes. The skilled worker will choose suitable auxiliaries in the customary manner to meet the specific requirements.
For example, further auxiliaries are selected among
(d1) solvents or diluents;
(d2) retention agents, pH buffers, antifoams.
Besides water, the compositions may comprise further solvents of soluble constituents, or diluents for insoluble constituents of the composition.
Substances which are useful in principle are, for example, mineral oils, synthetic oils and vegetable and animal oils, and low-molecular-weight hydrophilic solvents such as alcohols, ethers, ketones and the like.
Substances which must therefore be mentioned are, firstly, aprotic or apolar solvents or diluents, such as mineral oil fractions of medium to high boiling point, for example kerosene and diesel oil, furthermore coal tar oils, hydrocarbons, liquid paraffins, for example C8- to C30-hydrocarbons of the n- or iso-alkane series or mixtures of these, if appropriate, hydrogenated or partially hydrogenated aromatics or alkyl aromatics from the benzene or naphthalene series, for example aromatic or cycloaliphatic C7- to C18-hydrocarbon compounds, aliphatic or aromatic carboxylic acid or dicarboxylic acid esters, fats or oils of vegetable or animal origin, such as mono-, di- and triglycerides, in pure form or as a mixture, for example in the form of oily extracts from natural substances, for example olive oil, soy oil, sunflower oil, castor oil, sesame oil, corn oil, peanut oil, rapeseed oil, linseed oil, almond oil, castor oil, safflower oil, and their raffinates, for example hydrogenated or partially hydrogenated products thereof and/or their esters, in particular methyl and ethyl esters.
Examples of C8- to C30-hydrocarbons of the n- or iso-alkane series are n- and iso-octane, -decane, -hexadecane, -octadecane, -eicosane, and preferably hydrocarbon mixtures, such as liquid paraffin (which, if industrial-grade, may comprise up to approximately 5% aromatics) and a C18-C24-mixture which is commercially obtainable from Texaco under the name Spraytex oil.
The aromatic or cycloaliphatic C7- to C18-hydrocarbon compounds include, in particular, aromatic or cycloaliphatic solvents from the series of the alkyl aromatics. These compounds may be unhydrogenated, partially hydrogenated or fully hydrogenated. Such solvents include, in particular, mono-, di- or trialkylbenzenes, mono-, di-, trialkyl-substituted tetralins and/or mono-, di-, tri- or tetraalkyl-substituted naphthalenes (alkyl preferably represents C1-C6-alkyl). Examples of such solvents are toluene, o-, m-, p-xylene, ethylbenzene, isopropylbenzene, tert-butylbenzene and mixtures, such as the products from Exxon sold under the names Shellsol and Solvesso, for example Solvesso 100, 150 and 200.
Examples of suitable monocarboxylic acid esters are oleic esters, in particular methyl oleate and ethyl oleate, lauric acid esters, in particular 2-ethylhexyl laurate, octyl laurate and isopropyl laurate, isopropyl myristate, palmitic acid esters, in particular 2-ethylhexyl palmitate and isopropyl palmitate, stearic acid esters, in particular n-butyl stearate and 2-ethylhexyl 2-ethylhexanoate.
Examples of suitable dicarboxylic acid esters are adipic acid esters, in particular dimethyl adipate, di-n-butyl adipate, di-n-octyl adipate, di-iso-octyl adipate, also referred as bis-(2-ethylhexyl) adipate, di-n-nonyl adipate, di-iso-nonyl adipate and ditridecyl adipate; succinic acid esters, in particular di-n-octyl succinate and di-iso-octyl succinate, and di-(iso-nonyl)cyclohexane-1,2-dicarboxylate.
As a rule, the above-described aprotic solvents or diluents amount to less than 80%, preferably less than 50% and in particular less than 30% of the total weight of the composition.
Some of these aprotic solvents or diluents can also have adjuvant properties, i.e. in particular activity-enhancing properties. This applies in particular to said mono- and dicarboxylic acid esters. In accordance with this aspect, such adjuvants may also, as part of another formulation (stand-alone product), be mixed with the alcohol alkoxylates according to the invention, or with compositions comprising them, at a suitable point in time, as a rule shortly before application.
Secondly, protic or polar solvents or diluents must be mentioned, for example C2-C8-mono alcohols, such as ethanol, propanol, isopropanol, butanol, isobutanol, tert-butanol, cyclohexanol and 2-ethylhexanol, C3-C8-ketones, such as diethyl ketone, t-butyl methyl ketone, cyclohexanone and 2-sec-butylphenol, and aprotic amines, such as N-methyl- and N-octylpyrrolidone.
As a rule, the above-described protic or polar solvents or diluents amount to less than 80%, preferably less than 50% and in particular less than 30% of the total weight of the composition.
It is also possible to use antisettling agents, in particular for suspension concentrates. Such antisettling agents serve in particular the purpose of rheological stabilization. Substances which must be mentioned in this context are, in particular, mineral products, for examples bentonites, talcites and hectorites.
Other additives which may be useful can be found for example among mineral salt solutions, which are employed for alleviating nutritional and trace element deficiencies, nonphytotoxic oils and oil concentrates, antidrift reagents, antifoams, in particular those of the silicone type, for example Silicon SL, which is commercially obtainable from Wacker, and the like.
The formulations may be present as water-soluble concentrates (SL, LS), dispersible concentrates (DC), emulisifiable concentrates (EC), emulsions (EW, EO, ES), suspensions (SC, OD, FS), water-dispersible granules (WG, SG), water-dispersible or water-soluble powders (WP, SP, SS, WS) granules (GR, FG, GG, MG), ULV solutions (UL) or gel formulations (GF).
In accordance with a preferred embodiment, the compositions according to the invention are liquid formulations.
The compositions can be prepared in a manner known per se. To this end, at least some of the components are combined. It must be noted that products, in particular commercially available products, can be used whose constituents may contribute to different components. For example, a specific surfactant may be dissolved in an aprotic solvent, so that this product may contribute to various components. Furthermore, it is also possible, under certain circumstances, that small amounts of less desired substances are introduced together with commercially available products. As a mixture, the combined products must then, as a rule, be mixed finely with one another to give a homogeneous mixture and, if required, ground, for example in the case of suspensions.
Mixing can be effected in a manner known per se, for example by homogenizing with suitable devices such as KPG or magnetic stirrers.
Grinding, too, is a process which is known per se. Grinding media which may be employed are grinding media made of glass, or other mineral or metallic grinding media, as a rule in a size of from 0.1-30 mm and in particular of from 0.6-2 mm. As a rule, the mixture is ground until the desired particle size has been reached.
In general, grinding may be effected in the circulating mode, i.e. continuous recirculating of, for example, an SC, or by means of the batch mode, i.e. complete and repeated pumping through, or passing through, of a batch.
Grinding can be effected by means of traditional ball, bead or agitated-ball mills, for example in a Dyno-mill (from Bachofen), with batch sizes of from, for example, 0.5 up to 1 liter in what is known as the batch mode. After several batches, in particular 4 to 6 passes, (pumping the suspension through the mill with the aid of a roller pump), particle sizes of from 0.5 to 10 mm are achieved, according to evaluation under the microscope.
Before use, the compositions are converted into a suitable application form in the customary manner, as a rule by dilution. Dilution with water or else aprotic solvents, for example in the tank mix method, is preferred. The use in the form of a spray mixture preparation is preferred. It may be applied pre- or post-emergence. Post-emergence application leads to particular advantages.
The use according to the invention also comprises the use of the alkoxylates according to the invention as stand-alone product. To this end, the alkoxylates are prepared in a suitable manner in order to be added, shortly before application, to the product to be applied. As regards the ratio between alkoxylate and active ingredient, what has been said above in connection with the composition also applies here. In this sense, the combination according to the invention of active ingredient and adjuvant may also be provided in the form of a kit. Such a kit comprises at least two containers. One container comprises at least one active ingredient for the treatment of plants, if appropriate formulated as a composition together with expedient auxiliaries. A further container comprises at least one alcohol alkoxylate of the formula (I).
Particular advantages result especially in the case of a spray application. For a conventional tank-mix spray mixture, the compositions, which already comprise an alkoxylated branched alcohol,—or further plant treatment compositions with the addition of at least one alkoxylated branched alcohol as stand-alone product—are diluted with water in such a way that approximately 0.01 to 10, preferably approximately 0.05 to 5 and in particular 0.1 to 1 kg of at least one alkoxylate according to the invention are applied per ha.
In the context of the present description, quantities generally refer to the total weight of a composition, unless otherwise specified. In accordance with the invention, the term “essentially” generally relates to a percentage ratio of at least 80% or preferably at least 90% and in particular at least 95%.
