Halogen-substituted radicals, e.g. haloalkyl, are mono- or polyhalogenated up to the maximum possible number of substituents. In the case of polyhalogenation, the halogen atoms may be the same or different. Halogen is fluorine, chlorine, bromine or iodine, especially fluorine, chlorine or bromine.
Preference, particular preference or very particular preference is given to compounds which in each case bear the substituents specified under preferred, particularly preferred or very particularly preferred.
Saturated or unsaturated hydrocarbon radicals such as alkyl or alkenyl may, also in conjunction with heteroatoms, for example in alkoxy, where possible, each be straight-chain or branched.
Optionally substituted radicals may be mono- or polysubstituted, where the substituents may be the same or different in the case of polysubstitutions.
The radical definitions and illustrations listed above in general terms or listed in preferred ranges can, however, also be combined with one another as desired, i.e. between the particular ranges and preferred ranges.
The active ingredients can be used in the inventive compositions within a wide concentration range. The concentration of the active ingredients in the formulation is typically 0.1-50% by weight.
In the literature, it has already been stated that the action of different active ingredients can be enhanced by adding ammonium or phosphonium salts. However, these are salts which act as a detergent (e.g. WO 95/017817) or salts with relatively long alkyl and/or aryl substituents which have permeabilizing action or increase the solubility of the active ingredient (for example
EP-A 0 453 086, EP-A 0 664 081, FR-A 2 600 494, U.S. Pat. No. 4,844,734, U.S. Pat. No. 5,462,912, U.S. Pat. No. 5,538,937, U.S. Pat. No. 03/0,224,939, U.S. Pat. No. 05/0,009,880, U.S. Pat. No. 05/0,096,386). In addition, the prior art describes the effect only for particular active ingredients and/or particular uses of the corresponding compositions. In other cases again, the salts are those of sulphonic acids in which the acids themselves have paralysing action on insects (U.S. Pat. No. 2,842,476). An enhancement of action by ammonium sulphate has been described for the herbicides glyphosate and phosphinothricin (U.S. Pat. No. 6,645,914, EP-A 0 036 106). A corresponding effect in the case of the inventive insecticides is neither disclosed nor suggested by this prior art.
The use of ammonium sulphate as a formulating assistant has also been described for particular active ingredients and uses (WO 92/16108), but it serves there to stabilize the formulation, not to enhance the action.
It has now been found that, completely surprisingly, the action of insecticidal enaminocarbonyl compounds can be enhanced significantly through the addition of ammonium and/or phosphonium salts to the use solution (tankmix application) or through the incorporation of these salts into a formulation comprising such insecticides. The present invention thus provides for the use of ammonium and/or phosphonium salts for enhancing the action of crop protection compositions which comprise insecticidally active enaminocarbonyl compounds. The invention likewise provides compositions which comprise such insecticides and action-enhancing ammonium and/or phosphonium salts, specifically both formulated active ingredients and ready-to-use compositions (spray liquors). The invention finally further provides for the use of these compositions for controlling harmful insects.
Ammonium and phosphonium salts which, in accordance with the invention, enhance the action of crop protection compositions comprising enaminocarbonyl compounds are defined by formula (II)
in which
The ammonium and phosphonium salts of the formula (II) can be used within a wide concentration range to enhance the action of crop protection compositions comprising enaminocarbonyl compounds. In general, the ammonium or phosphonium salts are used in a ready-to-use crop protection composition in a concentration of 0.5 to 80 mmol/1, preferably 0.75 to 37.5 mmol/1, more preferably 1.5 to 25 mmol/1. In the case of a formulated product, the ammonium and/or phosphonium salt concentration in the formulation is selected such that, after dilution of the formulation to the desired active ingredient concentration, it is within these stated general, preferred or particularly preferred ranges. The concentration of the salt in the formulation is typically 1-50% by weight.
In a preferred embodiment of the invention, not only an ammonium and/or phosphonium salt but additionally a penetrant is added to the crop protection compositions to enhance the action. It can be described as completely surprising that, even in these cases, an even greater enhancement of action is observed. The present invention thus likewise provides for the use of a combination of penetrant and ammonium and/or phosphonium salts for enhancing the action of crop protection compositions which comprise insecticidally active enaminocarbonyl compounds as an active ingredient. The invention likewise provides compositions which comprise insecticidally active enaminocarbonyl compounds, penetrants and ammonium and/or phosphonium salts, both in the form of formulated active ingredients and of ready-to-use compositions (spray liquors). The invention finally further provides for the use of these compositions for controlling harmful insects.
Useful penetrants in the present context include all of those substances which are typically used in order to improve the penetration of active agrochemical ingredients into plants. In this connection, penetrants are defined such that they penetrate from the aqueous spray liquor and/or from the sprayed coating into the cuticle of the plant and thus increase the mobility of active ingredients in the cuticle. The method described in the literature (Baur et al., 1997, Pesticide Science 51, 131-152) can be used to determine this property.
Useful penetrants include, for example, alkanol alkoxylates. Inventive penetrants are alkanol alkoxylates of the formula
R—O—(-AO)v—R′ (III)
in which
A preferred group of penetrants is that of alkanol alkoxylates of the formula
R—O—(-EO—)m—R′ (III-a)
in which
A further preferred group of penetrants is that of alkanol alkoxylates of the formula
R—O—(-EO—)p—(—PO—)q—R′ (III-b)
in which
A further preferred group of penetrants is that of alkanol alkoxylates of the formula
R—O—(—PO—)r—(EO—)s—R′ (III-c)
in which
A further preferred group of penetrants is that of alkanol alkoxylates of the formula
R—O—(-EO—)v—(—BO—)x—R′ (III-d)
in which
A further preferred group of penetrants is that of alkanol alkoxylates of the formula
R—O—(—BO—)y—(-EO—)z—R′ (III-e)
in which
A further preferred group of penetrants is that of alkanol alkoxylates of the formula
CH3—(CH2)t—CH2—O—(—CH2—CH2—O—)u—R′ (III-f)
in which
In the above-specified formulae,
R is preferably butyl, i-butyl, n-pentyl, i-pentyl, neopentyl, n-hexyl, i-hexyl, n-octyl, i-octyl, 2-ethylhexyl, nonyl, i-nonyl, decyl, n-dodecyl, i-dodecyl, lauryl, myristyl, i-tridecyl, trimethylnonyl, palmityl, stearyl or eicosyl.
One example of an alkanol alkoxylate of the formula (III-c) is 2-ethylhexyl alkoxylate of the formula
in which
and
the numbers 8 and 6 are average values.
One example of an alkanol alkoxylate of the formula (III-d) is the formula
CH3—(CH2)10—O—(-EO—)6—BO—)2—CH3 (III-d-1)
in which
and
the numbers 10, 6 and 2 are average values.
Particularly preferred alkanol alkoxylates of the formula (III-f) are compounds of this formula in which
Very particular preference is given to alkanol alkoxylate of the formula (III-f-1)
CH3—(CH2)t—CH2—O—(—CH2—CH2—O—)u—H (III-f-1)
in which
The alkanol alkoxylates are defined in general by the above formulae. These substances are mixtures of substances of the type specified with different chain lengths. For the indices, average values which may also deviate from integer values are therefore calculated.
The alkanol alkoxylates of the formulae specified are known, and some of them are commercially available or can be prepared by known methods (cf. WO 98-35 553, WO 00-35 278 and EP-A 0 681 865).
Useful penetrants are, for example, also substances which promote the solubility of the compounds of the formula (I) in the spray covering. These include, for example, mineral or vegetable oils. Useful oils include all mineral or vegetable oils, optionally modified, which are typically useable in agrochemical compositions. Examples include sunflower oil, rapeseed oil, olive oil, castor oil, colza oil, maize kernel oil, cottonseed oil, and soybean oil, or the esters of the oils mentioned. Preference is given to rapeseed oil, sunflower oil, and their methyl or ethyl esters. Particular preference is given to rapeseed oil methyl ester.
The concentration of penetrants in the inventive compositions can vary within a wide range. In the case of a formulated crop protection composition, it is generally 1 to 95% by weight, preferably 1 to 55% by weight, more preferably 15-40% by weight. In the ready-to-use compositions (spray liquors), the concentration is generally between 0.1 and 10 g/l, preferably between 0.5 and 5 g/l.
Combinations of active ingredient, salt and penetrant which are prominent in accordance with the invention are listed in the table which follows, each individual combination being prominent on its own. “According to test” means that any compound which acts as a penetrant in the test for cuticle penetration is suitable (Baur et al., 1997, Pesticide Science 51, 131-152).
Inventive crop protection compositions may also comprise further components, for example surfactants or dispersion aids or emulsifiers.
Useful nonionic surfactants or dispersion aids include all substances of this type typically useable in agrochemical formulations. Preference is given to polyethylene oxide-polypropylene oxide block copolymers polyethylene glycol ethers of linear alcohols, reaction products of fatty acids with ethylene oxide and/or propylene oxide, and also polyvinyl alcohol, polyvinylpyrrolidone, copolymers of polyvinyl alcohol and polyvinylpyrrolidone, and also copolymers of (meth)acrylic acid and (meth)acrylic esters, and also alkyl ethoxylates and alkylaryl ethoxylates, which may optionally have been phosphated and may optionally have been neutralized with bases, the examples including sorbitol ethoxylates, and also polyalkylenamine derivatives.
Useful anionic surfactants include all substances of this type which are typically used in agrochemical formulations. Preference is given to alkali metal and alkaline earth metal salts of alkylsulphonic acids or alkylarylsulphonic acids.
A further preferred group of anionic surfactants or dispersion aids is that of salts, each of which is of low solubility in vegetable oil, of polystyrenesulphonic acids, those of polyvinylsulphonic acids, those of naphthalenesulphonic acid-formaldehyde condensation products, those of condensation products of naphthalenesulphonic acid, phenol and formaldehyde, and those of lignosulphonic acid.
Useful additives which may be present in the inventive formulations include emulsifiers, foam inhibitors, preservatives, antioxidants, dyes and inert filler materials.
Preferred emulsifiers are ethoxylated nonylphenols, reaction products of alkylphenols with ethylene oxide and/or propylene oxide, ethoxylated arylalkylphenols, and also ethoxylated and propoxylated arylalkylphenols, and also sulphated or phosphated arylalkyl ethoxylates or ethoxypropoxylates, examples including sorbitan derivatives such as polyethylene oxide-sorbitan fatty acid esters and sorbitan fatty acid esters.
The examples which follow serve to illustrate the invention and should in no way be interpreted as restrictive.
