The present invention relates to certain alcohol alkoxylates of the amphiphilic type, agrochemical compositions comprising these, 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, optionally, 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.
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. 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.
WO 03/090531 describes the use of alkoxylates of certain branched alcohols, which include in particular 2-propylheptanol, C13-oxo alcohols and C10-oxo alcohols, as adjuvant for the agrochemical sector. Similar alcohol alkoxylates are proposed in WO 2005/015998 specifically as adjuvant for fungicidal benzamide oxime derivatives. WO 00/35278 relates to agrochemical formulations based on PO/EO block copolymers of 2-ethylhexanol. The EO/PO-EO alkoxylates described in WO 99/03345 as adjuvant for improving the activity of a pesticide and plant protection composition are based on alcohols having more than 14 carbon atoms. WO 2005/084435 describes oil-based suspension concentrates which comprise one of the two end group-capped alcohol block alkoxylates CH3—(CH2)10—O-(EO)—6—(BO)2—CH3 or CH3—(CH2)8—O-(EO)—6—(BO)2—CH3 as penetrant. These end-group capped alcohol block alkoxylates are said to have a better activity than comparable alkoxylates without end group cap.
Thus, all of these alcohol alkoxylates are based on long-chain alcohols having at least 8 carbon atoms. However, individual alcohol alkoxylates based on short-chain alcohols are also known.
Thus, U.S. Pat. No. 6,071,857, for example, describes liquid pesticide compositions comprising the surface-active butanol EO/PO block alkoxylate known under the trade name Witconol NS 500 K®.
JP 02049701 describes crop protection granules comprising, as disintegrant, EO/PO alkoxylates of n-butanol.
EP 0 261 492 describes suspoemulsions comprising a surface-active ethylene oxide/propylene oxide block polymer having a relatively high average molecular weight for stabilizing the suspoemulsion.
JP 06313191 describes the use of the alcohol alkoxylates C4H9—O—(C3H6O)2—(C2H4O)8—(C3H6O)2—H, C4H9—O—(C3H6O)4—(C2H4O)12—(C3H6O)1—H and C6H13—O—(C3H6O)2—(C2H4O)12—(C3H6O)1—H in detergents and cleaners.
GB 2 109 403 describes the use of a mono-C1-C6-alkyl ether of ethoxylate/propoxylate copolymers having an ethoxylate:propoxylate weight ratio in the range of from 30:70 to 5:95 in textile finishing compositions.
JP 2001 163813 describes alcohol alkoxylates of the C4-C8-alkyl-O—(C2H4O)1-2—(C3H6O)0.1-1—(C2H4O)1-5—H type and their use as solvents or heat exchangers.
JP 09 031004 appears to describe EO/PO alkoxylates of heptanols and their use as solvents having surface-active and emulsifying action.
WO 2006/070816 appears to describe EO/PO alkoxylates of n-propanol and their use as surfactant for forming a stable foam.
U.S. Pat. No. 6,025,318 describes detergents and cleaners comprising EO/PO alkoxylates of iso-C1-3-alcohols and hexanol.
However, none of these publications considers the use of the alcohol alkoxylates based on short-chain alcohols as activity-enhancing adjuvant in the crop protection field.
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 means of specific alkoxylates of short-chain alcohols, including in particular PO/EO, EO/PO and EO/PO/EO block alkoxylates and BO/EO, EO/BO and EO/BO/EO block alkoxylates, their use as adjuvant, and agrochemical compositions which comprise these alkoxylates.
The present invention relates to alkoxylated alcohols of the formula (I)
R—O—(CmH2mO)q—[(C2H4O)z—(CnH2nO)x—(C2H4O)y]co—Z (I)
in which

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)

Special effects are obtained by the compositions according to the invention in the cultivation of Allium cepa, Hordeum vulgare, Triticum aestivum and Triticum durum.
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.
The alcohol moiety of the alcohol alkoxylates according to the invention is, as a rule, based on alcohols or alcohol mixtures having 1 to 7 and in particular either 1 to 3, 4, or 5 to 7, i.e. 5, 6 or 7, carbon atoms, which alcohols or alcohol mixtures are known per se. R in formula (I) thus represents in particular methyl, ethyl, n-propyl, isopropyl, n-butyl, 2-butyl, isobutyl or tert-butyl, n-pentyl, 1-methylbutyl, 2-methylbutyl, 3-methylbutyl, 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-dimethylbutyl, 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-methylpropyl, 2-ethyl-2-methylpropyl, n-heptyl, 1-methylhexyl, 2-methylhexyl, 3-methylhexyl, 4-methylhexyl, 5-methylhexyl, 1,1-dimethylpentyl, 1,2-dimethylpentyl, 1,3-dimethylpentyl, 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-trimethylbutyl, 1,2,3-trimethylbutyl, 1,3,3-trimethylbutyl, 1-ethyl-1-methylbutyl, 1-ethyl-2-methylbutyl, 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-methylbutyl, 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.
The alcohol moiety of the alkoxylates is therefore linear or branched. The linear alcohols include in particular methanol, ethanol, n-propanol, n-butanol, n-pentanol and n-hexanol, moreover n-heptanol. Among the branched alcohols, the branched pentanols (amyl alcohols), which are frequently used as a mixture, must be mentioned in particular. Those having 5, 6 or 7 carbon atoms have proven to be particularly advantageous.
According to a particular embodiment, the alkoxylated alcohol is selected from among alkoxylated alcohols of the formula (I) where q is 1, 2 or 3. Such alcohol alkoxylates can be prepared in a targeted fashion, for example by alkoxylating in the above-described manner and, optionally, end-group capping, a compound of the formula (XI)
R—O—(CmH2mO)q—H (XI)
in which
R, m and q are as defined herein.
The compounds of the formula (XI) are mono-C1-C7-alkyl ethers of ethylene glycol (m=2; q=1), propylene glycol (m=3; q=1), diethylene glycol (m=2; q=2), dipropylene glycol (m=3; q=2), triethylene glycol (m=2; q=3) or tripropylene glycol (m=3; q=3) which are known per se.
Of particular importance in accordance with the invention are the alkyl ethers of mono-, di- and tripropylene glycol of the formula (XIa)
R—O—(CH2CH(CH3)O)q—H (XIa)
in which R and q are as defined herein.
In accordance with another aspect, the mono-C1-C4-alkyl ethers (i.e. R is in particular C1-C4-alkyl), and of these mainly the dipropylene glycol monoalkyl ethers (q=2), must be emphasized. These 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 can be obtained both from native sources and via the synthetic route, for example by composing them from starting materials with a lower number of carbon atoms.
The alkoxylation is the result of the reaction with suitable alkylene oxides, namely with ethylene oxide (EO) and at least one higher alkylene oxide having 3 to 16 and preferably 3 to 6 carbon atoms, of which in particular 1,2-propylene oxide (PO), 1,2-butylene oxide (BO), 1,2-pentylene oxide (PeO) and 1,2-hexylene oxide (HO) may be mentioned. Furthermore, 1,2-decylene oxide (DeO) may also be mentioned.
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 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 ethylene oxide and higher alkylene oxide employed in their preparation, and by the reaction conditions. On the one hand, the alcohol alkoxylates according to the invention preferably comprise at least or more than approximately 2, more preferably at least or more than approximately 4, in particular at least or more than approximately 6, above all at least or more than approximately 8, and especially preferably at least or more than approximately 10 alkylene oxide units. On the other hand, the alcohol alkoxylates according to the invention preferably comprise not more than or less than approximately 100, 90 or 85, more preferably not more than or less than approximately 80, 70 or 65, in particular not more than or less than approximately 60, 50 or 45, above all not more than or less than approximately 40 or 35, and especially preferably not more than or less than approximately 30 or 25 alkylene oxide units. Accordingly, preference is given, for example, to alcohol alkoxylates having about 2 to 100, 90 or 85, such as about 4 to 80, 70 or 65, in particular about 6 to 60, 50 or 45, especially about 8 to 40 or 35, and particularly about 10 to 30 or 25 alkylene oxide units (x+y+z). If y=zero, preference is thus given, for example, to alcohol alkoxylates having about 2 to 100, 90 or 85, such as about 4 to 80, 70 or 65, in particular about 6 to 60, 50 or 45, especially about 8 to 40 or 35, and particularly about 10 to 30 or 25 alkylene oxide units (z+x). If z=zero, preference is thus given, for example, to alcohol alkoxylates having about 2 to 100, 90 or 85, such as about 4 to 80, 70 or 65, in particular about 6 to 60, 50 or 45, especially about 8 to 40 or 35, and particularly about 10 to 30 or 25 alkylene oxide units (x+y).
According to a particular embodiment, the invention relates to alcohol alkoxylates of the formula (I) in which the value of x is greater than the value of z, than the value of y or than the sum of z and y. These are alcohol alkoxylates having more units of the higher alkylene oxide than ethylene oxide units. This applies especially to alcohol alkoxylates of the formula (I), in which n is 3.
On the one hand, such alcohol alkoxylates have an alkoxylate moiety in which the ratio of higher alkylene oxide to ethylene oxide (x to z, x to y or x to (z+y)) is at least or more than 1.1:1, preferably at least or more than 1.5:1, especially at least or more than 1.8:1, and in particular at least or more than 2:1, for example at least or more than 3:1.
On the other hand, such alcohol alkoxylates have an alkoxylate moiety in which the ratio of higher alkylene oxide to ethylene oxide (x to z, x to y or x to (z+y)) is at most or less than 25:1, preferably at most or less than 15:1, and in particular at most or less than 10:1, for example at most or less than 4.3:1. Preference is thus given to alkoxylates in which the ratio of higher alkylene oxide to ethylene oxide (x to z, x to y or x to (z+y)) is from 1.1:1 to 25:1, preferably from 1.5:1 to 15:1, especially from 1.8 to 15:1, and in particular from 2:1 to 10:1, for example from 2.3:1 to 4.3:1. This applies especially to alcohol alkoxylates of the formula (I) in which n is 3 or 4.
According to a further particular embodiment, the invention relates to alcohol alkoxylates of the formula (I) in which the value x is less than the value of z, than the value of y or than the sum of z and y. These are alcohol alkoxylates having fewer units of the higher alkylene oxide than ethylene oxide units. This applies especially to alcohol alkoxylates of the formula (I) in which n is greater than 3, that is 4, or especially 5, 6 or 10.
On the one hand, such alcohol alkoxylates have an alkoxylate moiety in which the ratio of ethylene oxide to higher alkylene oxide (z to x, y to x or (z+y) to x) is at least or more than 1.1:1, preferably at least or more than 1.5:1, especially at least or more than 2:1, and in particular at least or more than 2.5:1, for example at least or more than 3:1. On the other hand, such alcohol alkoxylates have an alkoxylate moiety in which the ratio of ethylene oxide to higher alkylene oxide (z to x, y to x or (z+y) to x) is at most or less than 25:1, preferably at most or less than 20:1, and in particular at most or less than 15:1, for example at most or less than 10:1. Preference is thus given to alcohol alkoxylates in which the ratio of ethylene oxide to higher alkylene oxide (z to x, y to x or (z+y) to x) is from 1.1:1 to 25:1, preferably from 1.5:1 to 20:1 and in particular from 2:1 to 15:1, for example from 2.5:1 to 10:1. This applies especially to alcohol alkoxylates of the formula (I) in which n is greater than 3, i.e. especially 5, 6 or 10.
The degree of alkoxylation (value of x) which can be attributed to the higher alkylene oxide units is, on the one hand, generally from 1 to 50, preferably from 3 to 30 and in particular from 5 to 20. This applies especially to alcohol alkoxylates of the formula (I) in which n is 3 or 4.
The degree of alkoxylation (value of x) which can be attributed to the higher alkylene oxide units is, on the other hand, generally from 1 to 30, preferably from 2 to 20 and in particular from 3 to 15. This applies especially to alcohol alkoxylates of the formula (I) in which n is greater than 3, i.e. 4, or especially 5, 6 or 10.
The degree of alkoxylation (value of z, y or (z+y)) which can be attributed to the ethylene oxide units is, on the one hand, generally from 1 to 30, preferably from 2 to 20 and in particular from 3 to 10. This applies especially to alcohol alkoxylates of the formula (I) in which n is 3 or 4.
The degree of alkoxylation (value of z, y or (z+y)) which can be attributed to the ethylene oxide units is, on the other hand, generally from 1 to 50, preferably from 3 to 40 and in particular from 5 to 30. This applies especially to alcohol alkoxylates of the formula (I) in which n is greater than 3, i.e. 4, or especially 5, 6 or 10.
A particular embodiment are alcohol alkoxylates of the formula (I) in which z is zero, i.e. alkoxylated alcohols of the formula (Ia)
R—O—(CmH2mO)q—[(CnH2nO)x—(C2H4O)y]co—Z (Ia)
in which R, m, q, n, x, y, Z are as defined herein and y is greater than zero.
A further particular embodiment are alcohol alkoxylates of the formula (I) in which y and z are greater than zero.
The reaction of the alcohols or alcohol mixtures with the alkylene oxide(s) is carried out by customary processes 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, Brønsted 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 alkylene oxide may comprise a mixture of inert gas, for example approximately 5 to 60%.
In the formulae (I) and (Ia), the alkylene oxide units and ethylene oxide units, if present, may be arranged in any way. Thus, the structural unit [ . . . ]co can be a random copolymer, a gradient copolymer, an alternating copolymer or a block copolymer of alkylene oxide units CnH2nO and ethylene oxide units C2H4O.
—CnH2nO— (where n is 3 or greater) represents either —CH(Cn-2H2n-3)CH2O— (for example —CH(CH3)CH2O—) or —CH2CH(Cn-2H2n-3)O— (for example —CH2CH(CH3)O—). Here, a specific alcohol alkoxylate may comprise essentially 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 both of 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 can be randomly distributed, alternating or arranged in two or more sub-blocks. The base-catalyzed alkoxylation generates predominantly alkylene oxide units of the formula —CH2CH(Cn-2H2n-3)O—, since the attack of the anion preferably takes place at the sterically less hindered secondary carbon atom of the alkylene oxide. Customary molar ratios are 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—.
According to a particular embodiment, the alkoxylated alcohol is selected from alcohol block alkoxylates of the formula (II)
R—O—(CmH2mO)q—(C2H4O)z—(CnH2nO)x—(C2H4O)y—Z (II)
in which R, m, q, n, x, y, z, Z are as defined herein. If both z and y are greater than zero, these are triblock alkoxylates, for example EO/PO/EO block alkoxylates.
The alcohol block alkoxylates of the formula (II) include in particular alkoxylated alcohols of the formula (IIa)
R—O—(CmH2mO)q—(CnH2nO)x—(C2H4O)y—Z (IIa),
in which, m, q, n, x, y, Z are as defined herein and y is greater than zero. These are alcohol alkoxylates having an ethylene oxide block and a higher alkylene oxide block, where the ethylene oxide block is arranged terminally, for example PO/EO, BO/EO, PeO/EO or DeO/PO block alkoxylates.

One particular embodiment is alcohol alkoxylates according to the invention which are not end-group capped (Z═H).
In accordance with a further preferred embodiment, the alcohol alkoxylates according to the invention are end-group 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-group capped alcohol alkoxylates can be prepared in a manner known per se by reacting the non-end-group 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 2000 g/mol. Preferred are alcohol alkoxylates with a molecular weight of less than 1800 g/mol, less than 1700 g/mol, or less than 1500 g/mol. In accordance with a particular embodiment, the molecular weight is less than 1400 g/mol.
The weight-average molecular weight of alcohol alkoxylates which are suitable in accordance with the invention is, as a rule, less than 2000 g/mol. Preferred are alcohol alkoxylates with a molecular weight of less than 1800 g/mol, less than 1700 g/mol, or less than 1500 g/mol. In accordance with a particular embodiment, the molecular weight is less than 1400 g/mol. The weight-average molecular weight data relate to the determination by means of gel permeation chromatography according to DIN 55672.
The term “degree of branching” of R is here defined in a manner which is known in principle as the number of methyl groups in R minus 1. The same applies analogously to Z. The degree of branching of the alkoxylate moiety is calculated from the degree of alkoxylation and the alkylene oxides involved in the alkoxylation. The mean degree of branching is the statistic mean of the degrees of branching of all molecules of a sample.
The mean degree of branching can be determined by 1H NMR spectroscopy as shown hereinbelow for primary and/or secondary alcohols: To this end, a sample of the alcohol is first derivatized with trichloroacetyl isocyanate (TAI). In this process, the alcohols are converted into the carbamic esters. The signals of the esterified primary alcohols are at δ=4.7 to 4.0 ppm, those of the esterified secondary alcohols at approximately 5 ppm, and water present in the sample reacts with TAI to give carbamic acid. All methyl, methylene and methyne protons are in the range of from 2.4 to 0.4 ppm. The signals<1 ppm are assigned to the methyl groups. The mean degree of branching (iso-index) can be calculated from the spectrum thus obtained as follows:
iso-index=((F(CH3)/3)/(F(CH2—OH)/2+F(CHR—OH)))−1
where F(CH3) is the signal area which corresponds to the methyl protons, F(CH2—OH) the signal area of the methylene protons in the CH2—OH group and F(CHR—OH) the signal area of the methyne protons in the CHR—OH group.
Amounts of component (b), i.e. of alcohol alkoxylate based on the total weight of the composition according to the invention 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) based on the total weight of the composition of less than 50% by weight, preferably less than 45% by weight and in particular less than 40% by weight, are, as a rule, expedient.
The plant treatment agent 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).

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.

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.

The cationic surfactants include, for example, quaternized ammonium compounds, in particular alkyltrimethylammonium and dialkyldimethylammonium halides and alkyltrimethylammonium and dialkyldimethylammonium alkyl sulfates, and pyridine and imidazoline derivatives, in particular alkylpyridinium halides.
The nonionic surfactants include, for example, further alkoxylates and especially ethoxylates, and nonionic surfactants, in particular

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.
The further surfactant within the scope of component (c) is preferably selected among nonionic surfactants. Among these, surfactants with HLB values in the range from 2 to 16, preferably in the range from 5 to 16 and in particular in the range of from 8 to 16, are preferred.

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, optionally, 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 Shelisol 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 optionally 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.
In accordance with a preferred embodiment, the compositions according to the invention are liquid formulations.
The formulations may be present for example as emulsifiable concentrate (EC), suspoemulsion (SE), oil-in-water emulsion (0/W), water-in-oil emulsion (W/O), aqueous suspension concentrate, oil suspension concentrate (OD), microemulsion (ME).
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.
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%.
The invention is illustrated in greater detail by the examples which follow:
The weight-average molecular weights of the alkoxylates according to the invention can be determined by gel permeation chromatography as specified in DIN 55672.
Protocol for determining the iso-index of an alcohol mixture of secondary and/or primary alcohols via 1H NMR:
Approximately 20 mg of alcohol mixture are dissolved in 0.4 ml of CDCl3, and a small amount of TMS is added as the frequency reference. Thereafter, the solution is treated with 0.2 ml of TAI, charged into a 5 mm NMR tube and measured in the NMR spectrometer.

Here, the zero-order integral phases are selected in such a way that the beginning and the end of the integral curves are essentially horizontal. The signals<1 ppm are assigned to the methyl groups.

Leaves of wheat seedlings of the species “Kanzler” which had been grown in pots were dusted, in the two-leaf stage, with spores of leaf rust of wheat “Puccinia recondita” and incubated for 2 days in the greenhouse at high atmospheric humidity. In fully automated spray cabins, the plants were then sprayed with the formulations which comprised the active ingredients and adjuvants specified hereinbelow. The spray mixtures comprised 50 ppm epoxiconazole and 100 ppm adjuvant. The ratio active ingredient to adjuvant was, accordingly, 1:2. After the spray coatings had dried, the plants were returned to the greenhouse and grown at temperatures between 20 and 24° C. and a relative atmospheric humidity of 60 to 90%. After 10 days, the extent of the leaf rust disease was determined visually as disease percent of the total leaf area. 3 pots were evaluated for each combination.
