Abstract

Aids for agricultural resources, which it comprises a fatty alcohol polyalkoxyalkyl ether; and component selected from the group consisting of non-intestinal surfactants means, anionic active surfactants, cationic active surfactants, alkyl esters, for plants harmless mineral oils, water soluble silicone surfactants, dialkyl ethers fatty acids, dialkyl carbonates of fatty acids, vegetable oils and mixtures thereof.

Description

Auxiliary for agricultural preparations.

Technical field

The invention generally relates to the use of polyalkoxyalkyl ethers of fatty alcohols as emulsifiers, dispersants, wetting agents and solvents in auxiliary concentrates, pesticidal compositions and aqueous pesticidal compositions.

BACKGROUND OF THE INVENTION

Insecticides, insect repellents, fungicides, bactericides, bacteriostats, herbicides and plant growth regulators are usually formulated into various products suitable for crop treatment, insect control, weeds and the like. Alternatively, the compositions may be formulated as liquids, powders or granules. Solvents, emulsifiers, dispersants and wetting agents are typically incorporated into these compositions to ensure homogeneity of the pesticidal composition.

The components of these compositions are also selected to allow uniform dispersion or emulsification of the pesticidal composition in the mixing tank at the site of application. Said components may also have a third function to ensure optimal transfer of the composition obtained by mixing in the tank to the targeted pest or substrate. In some cases, when the compositions prepared in the tank contain multiple components, the surfactants incorporated into the pesticidal compositions do not fully ensure the complete stability of the compositions. Similarly, 4 44 44

4444 44 show the need to add auxiliaries to the mixture prepared in the tank to ensure its full stability.

In addition, it is known that the addition of surfactant-containing auxiliaries to the mixture in the tank makes it possible to achieve the desired stability. In addition, other proportions of surfactants have been shown to increase the pesticidal activity of many pesticides, and there are many co-formulations developed for this purpose. These compositions almost always contain surfactants ranging from minor components to a single component.

SUMMARY OF THE INVENTION

The invention relates to an auxiliary composition comprising:

(a) a fatty alcohol polyalkoxyalkyl ether; and

b) a component selected from the group consisting of non-ionic surfactants, anionic surfactants, cationic surfactants, alkyl esters, plant-grade mineral oils, water-soluble silicone surfactants, fatty dialkyl ethers, fatty dialkyl carbonates, vegetable oils and theirs mixtures.

The invention also relates to a pesticidal concentrate comprising:

(a) an auxiliary composition comprising:

i) a fatty alcohol polyalkoxyalkyl ether; and (ii) a component selected from the group consisting of non-ionic surfactants, anionic surfactants, cationic surfactants, alkyl esters, plant-grade mineral oils, water-soluble silicone surfactants, fatty dialkyl ethers, fatty dialkyl carbonates, vegetable oils and mixtures thereof; and

(b) a biologically active ingredient.

The invention also relates to a method of treating a targeted substrate comprising contacting the above pesticide concentrate with the substrate.

The polyalkoxyalkyl ethers of the fatty alcohols according to the invention can provide various functions in agricultural applications.

In various pesticidal and auxiliary compositions, they can function as emulsifiers, dispersants and wetting agents. Specifically, they can be used in emulsifiable concentrates, microemulsions, aqueous and oily liquid compositions. They can also be used as emulsifiers in crop adjuvant oil concentrates that contain both synthetic and vegetable oils. Polyalkoxyalkyl ethers of fatty alcohols are low sudsing surfactants which are highly stable in the presence of alkaline agents and acids. They are also readily biodegradable and their activity is not affected by hard water, which is often introduced into agricultural mixing tanks.

The polyalkoxyalkyl ethers of fatty alcohols according to the invention have the general formula I:

R ₁ - (EO) _x (PO) _y -R ₂ (I) wherein R 1 represents a monovalent organic radical of 6 to 22 carbon atoms, preferably from 12 to 18 carbon atoms, x represents a number from 1 to 10 and preferably from 2 to 6 y denotes a number from 0 to 10, R ₂ represents an alkyl group containing 1 to 12 carbon atoms and preferably from 3 to 6 carbon atoms. A particularly preferred fatty alcohol polyalkoxyalkylether for use herein is a compound wherein R1 is a C12-18 organic radical, x is 5, y is zero, and R2 is butyl. .

Examples of surfactants / solvents suitable for common use include, for example, other nonionic active surfactants such as ethoxylated castor oils, alcohol ethoxylates, alkyl polyglycosides, glucamides and the like, anionic surfactants such as fatty alcohol ether sulfates, phosphate esters, sulfonates and the like, cationic surfactants such as fatty ethoxylated amines and the like, alkyl esters such as methyloleate, ethylcanoate, and methyl soyate, non-vegetable mineral oils, water-soluble silicone surfactants, fatty dialkyl ethers, fatty dialkyl carbonates, vegetable oils such as canola oil, soybean oil and the like, and mixtures thereof, usually used in auxiliary and pesticidal compositions.

The co-surfactant / solvent of the present invention is present in the adjuvant composition in an amount of from about 1 to about 99% by weight, preferably from about 10 to about 95% by weight, and most preferably from about 25 to about 90% by weight of the auxiliary composition.

In another embodiment, the invention provides a pesticidal concentrate comprising a mixture of the above auxiliary composition and a biologically active ingredient.
