The invention relates to organic ammonium salts of anionic pesticides, to a process for preparation thereof, to agrochemical compositions comprising these salts, and to methods of controlling harmful organisms using the salts and compositions mentioned.
Pesticides (particularly herbicides, fungicides and insecticides) are chemical substances, prepared synthetically or of natural origin, which penetrate into plant cells or tissue or into parasitic organisms in or on the plant and damage and/or destroy them. The majority of pesticides are herbicides. Pesticides are typically used in the form of liquid or solid concentrated preparations (formulations) in agriculture. These are easier for the user to handle or ensure higher efficacy of the active ingredient. The formulations are typically diluted with water prior to use and then deployed by spray application.
Water-soluble concentrates (soluble liquids, abbreviated to SL) are an important form of pesticide preparations. They play a major role particularly in the case of herbicides, the pesticides often being used in the form of water-soluble salts which are converted to their alkali metal or ammonium salts by neutralization of the acid form of the herbicides with suitable bases. Under some circumstances, a second water-insoluble active ingredient is present in the pesticide preparation. In that case, the preparation is a suspension concentrate (SC), even when an active ingredient is dissolved in the aqueous phase.
A particularly important role is played by the water-soluble salts of herbicides, for example of glyphosate or glufosinate or of the auxin herbicides such as clodinafop, 2,4-D, MCAP or quinclorac. They are preferably used as the alkali metal salt or in the form of various ammonium salts or as a mixture of these salts, usually as aqueous formulations.
In the use of pesticides, it is advantageous when they have a low volatility, since a high volatility is especially associated with increased drift of relatively small spray droplets of droplet diameter below 150 mm of the pesticides, with high losses and ingress into the non-target vegetation on spraying. Such drift is undesirable for environmental and economic reasons, since unintended damage could be caused and the effect of the pesticides on the target organisms is lowered.
In order to avoid this effect, the use of volatile pesticides that are in the form of free acids in salt form is known.
U.S. Pat. No. 4,405,531 and WO 97/24931 disclose various organic salts of glyphosate with di- and polyamines.
U.S. Pat. No. 5,221,791 describes aminoalkylpyrrolidone salts of pesticides such as dicamba.
EP-A 0 375 624 discloses nonvolatile salts of pesticides with various polyamines.
EP-A 0 183 384 describes nonvolatile salts of dicamba with amino alcohols.
Even though good results are already achieved with the known systems, there is still a great deal of room for improvement, especially with regard to an increase in the water solubility of the active ingredients in the concentrate, lower volatility of the active ingredients and improved efficacy through better uptake.
It has now been found that the salts of mono- and dialkylglucamines with anionic pesticides are particularly suitable for use as aqueous spray applications.
The invention therefore provides an organic ammonium salt of the formula (I)
where the symbols have the following definitions:
The invention further provides a process for preparing an ammonium salt of the invention, wherein the protonated form of an anionic herbicide is reacted with a glucamine of the formula (II)
in which the symbols have the definitions given in the formula (I).
The invention further provides for the use of the ammonium salts of the invention as pesticides.
The invention likewise provides a pesticide composition comprising
The invention likewise provides a method of controlling harmful organisms, wherein the harmful organism or its habitat is brought into contact with an ammonium salt (I) of the invention or a pesticide composition of the invention.
The invention further provides for the use of an ammonium salt of the invention for reducing the volatility of the anionic pesticide present in salt form.
The ammonium salts (I) of the invention are of excellent suitability for use as aqueous spray applications and especially exhibit good water solubility and reduced volatility without elevated drift on use.
The cation of the ammonium salts (I) of the invention results from protonation of a glucamine (II)
where the symbols have the following definitions:
Preferably, the symbols in the formulae (I) and (II) have the following definitions:
Preference is given to cations in which all the symbols have the preferred definitions.
More preferably, the symbols in the formulae (I) and (II) have the following definitions:
Particular preference is given to cations in which all the symbols have the particularly preferred definitions.
Very particular preference is given to protonated dimethylglucamine (R1=CH3, R=H) and hydroxyethyl-glucamine (R1=CH2CH2OH, R=H).
The pentahydroxyhexyl radical in the alkylglucamines of the formula (I) and (II) has various chiral centers, such that several stereoisomers can exist in each case. Typically, the alkylglucamines of the formula (II) are prepared from naturally occurring sugars, such as D-glucose, but the use of other natural or synthetic hexoses or other C6 units is also possible in principle, such that different stereoisomers of the formulae (I) and (II) can be the result.
The preparation of the alkylglucamines of the formula (II) has been sufficiently described before and is known to the person skilled in the art. It is effected (for compounds with R1=C1-C4-alkyl), for example, as described in EP-A 1 676 831 by reductive alkylation of N-alkylpolyhydroxylamines with aldehydes or ketones in the presence of hydrogen and a transition metal catalyst.
Dimethylglucamine can be prepared, for example, according to EP-A 0 614 881. Dimethylglucamine is usable in the form of a 50% aqueous solution. Hydroxyethyl-N-methylglucamine can be prepared by reaction of N-methylglucamine with ethylene oxide in aqueous solution. Dimethylglucamine and hydroxyethyl-N-methylglucamine, being tertiary amines, are less prone to the formation of nitrosamines and are correspondingly preferred.
Compounds in which two adjacent R radicals together form a —C(R′)— group can be obtained by formation of the corresponding acetonide or acetal with acetone or with acetaldehyde or formaldehyde.
The alkylglucamines of the formula (II) are preferably based on renewable raw materials and feature an advantageous toxicological and environmental profile.

N-[2-(tert-butylcarbamoyl)-4-cyano-6-methylphenyl]-1-(3-chloro-pyridin-2-yl)-3-{[5-(trifluoromethyl)-2H-tetrazol-2-yl]methyl}-1H-pyrazole-5-carboxamide (known from WO2010/069502) and (1E)-N-[(6-chloropyridin-3-yl)methyl]-N′-cyano-N-(2,2-difluoroethyl)ethanimidamide (known from WO2008/009360).
The active ingredients referred to here by their common names are known and are described, for example, in the Pesticide Manual (16th ed., British Crop Protection Council 2012) or can be searched for on the Internet (e.g. http://www.alanwood.net/pesticides).
The pesticides of component c) may also be a combination of two or more pesticides. Such combinations are of significance especially when the aim is, for example, to broaden the spectrum of action of the pesticide composition or to better suppress resistances to particular pesticides.
In a preferred embodiment of the invention, the amount of the one or more pesticides of component c) in the compositions of the invention is more than 100 g/L, preferably more than 200 g/L and more preferably more than 300 g/L. These figures are based on the total weight of the pesticide composition of the invention and, in the case of pesticides which are used in the form of their water-soluble salts, are based on the amount of free acid, called the acid equivalent (a.e.).
The pH of the pesticide compositions is typically in the range from 3.5 to 8.5, preferably 4.0 to 8.0 and more preferably 4.5 to 6.5 (measured as a 1% by weight aqueous dilution). The pH is determined primarily by the pH values of the solutions of the aqueous pesticides that are in the form of salts of weak acids. By addition of acids or bases, it is possible to adjust the pH to another value different from the original pH of the mixture.
In a further preferred embodiment of the invention, the pesticide compositions of the invention are in the form of concentrate formulations which are diluted prior to use, especially with water (for example “ready-to-use”, “in-can” or “built-in” formulations), and contain the one or more ammonium salts (I) generally in amounts of 5% to 80% by weight, preferably of 10% to 70% by weight and more preferably of 20% to 60% by weight. These figures are based on the overall concentrate formulation.
The pesticide compositions of the invention are preferably deployed to the fields in the form of spray liquors. The spray liquors are produced by diluting concentrate formulations with a defined amount of water.
In a further preferred embodiment of the invention, the pesticide compositions of the invention are in the form of spray liquors and contain 0.001% to 10% by weight, preferably 0.02% to 3% by weight and more preferably 0.025% to 2% by weight of the one or more ammonium salts (I) of component a).
The invention further relates to the use of the pesticide compositions of the invention for control and/or for abatement of weeds, fungal diseases or insect infestation. Preference is given to the use of the compositions of the invention for control and/or for abatement of weeds.
These uses can preferably also take place in what is known as the tankmix method. In this case, the one or more water-soluble pesticides of component g) and components a) to d) and additionally water may thus also take the form of a “tankmix” preparation. In such a preparation, both the one or more water-soluble pesticides and components a) to d), the latter optionally together with further adjuvants, are present separately from one another. The two preparations are mixed with one another prior to deployment, generally shortly beforehand, giving rise to a pesticide composition of the invention.
The invention also provides a method of controlling harmful organisms, wherein the harmful organism or its habitat is brought into contact with an ammonium salt (I) of the invention or a pesticide composition of the invention. The harmful organisms are preferably unwanted plants, in which case the pesticide is correspondingly a herbicide or a mixture of herbicides.
