Description

PREPARATION CONTAINING FATTY ALCOHOL ETOXYLATES WITH A CLOSE ALKYL LENGTH RANGE AS A PART OF THE ADJUVANT MIXTURE FOR PESTICIDE PREPARATION

Technical field

The present invention generally relates to the use of narrow-range alkyl alcohol ethoxylates as emulsifiers, dispersants, humectants and solvents for adjuvant concentrates, pesticides and aqueous pesticidal formulations.

BACKGROUND OF THE INVENTION

Insecticides, insect repellents, fungicides, bactericides, bacteriostats, herbicides and plant growth regulators are normally in the form of various products for use in crop protection, insect control, weed control and the like. Alternatively, these products may be in the form of liquids, powders or granules. Solvents, emulsifiers, dispersants and humectants are normally added to such formulations to ensure the preparation of uniform pesticidal forms. The components of these forms are selected such that the pesticidal composition is dispersed or emulsified evenly. They have a third purpose to provide a mixing tank at the time of application to ensure that the optimal delivery of the formulation from the mixing tank to the surfactants added to it cannot completely ensure such mixtures contain a lot of pest or substrate. These pesticide formulations sometimes stability mixtures in the tank unless the ingredients. Similarly, adjuvants may be added to the tank mixture for full stability. It is generally known that by adding adjuvant compositions containing surfactants to the composition in the tank, desirable stability is achieved. In addition, sufficient amounts of surfactants have been shown to enhance the pesticidal activity of many pesticides, and there are a number of adjuvant compositions that have been developed for this purpose. The components of these adjuvant compositions are almost always surfactants ranging from minor components to a single component.

SUMMARY OF THE INVENTION

The present invention is directed to an adjuvant composition comprising:

(a) a narrow range alkyl alcohol ethoxylate; and

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

The present invention is also directed to a pesticide concentrate comprising:

(a) an adjuvant composition comprising

(i) a narrow alkyl alcohol fatty alcohol ethoxylate; and (ii) a component selected from the group consisting of non-ionic surfactants, cationic surfactants, alkyl esters, plant-friendly mineral oils, water-soluble silicone surfactants, fatty dialkyl ethers, fatty dialkyl carboxylates, fatty dialkyl carboxylates mixtures, and

(b) a biologically active ingredient.

The present invention is also directed to a method of treating a target substrate, including contacting the target substrate with said pesticidal concentrate.

Brief description of several drawings - cannot be logged

All numbers used herein, referring to the amounts of the ingredients or reaction conditions - except those mentioned in the claims or examples, or otherwise indicated - are to be understood as having the term "about.

The term "target substrate" is used herein to mean a plant, a pest on a plant, or a combination of a plant and a pest on a plant. A pest on a plant is defined as any stage of life of any weeds, insects, mites, nematodes, slugs, gastropods, protozoa or other invertebrate animals, bacteria, fungi, or other parasitic plants or their reproductive parts, viruses or other organisms just mentioned similar or related to them, or any infectious substance which may directly or indirectly cause injury, disease or damage to any plant or part of it or to any product produced from or produced by plants.

Fatty alcohol ethoxylates with a narrow alkyl length range can perform various functions in agricultural applications according to the present invention. They can serve as emulsifiers and humectants for many pesticides and adjuvants. In particular, they can be used in emulsifiable concentrates, microemulsions, aqueous flow-enhancing agents and oily flow-enhancing agents. They can also be used as crop oil adjuvant concentrates based on synthetic as well as vegetable oils.

Suitable narrow-range alkyl alcohol ethoxylates useful in the present invention include, but are not limited to, those derived from C6 to C22 fatty alcohols.

Another embodiment of the present invention consists of a pesticide concentrate comprising:

a) 99.9 to 5% by weight, more preferably 95 to 15% by weight, preferably up to 20% by weight of the above adjuvant mixture, and

b) 0.1 to 95% by weight, more preferably 5 to 85% by weight, preferably 10 to 80% by weight of the biologically active ingredient.

The exact amount of the biologically active ingredient that the pesticide concentrate contains often depends on the particular end application, i.e. the target substrate to be treated, the area to be treated, etc. Thus, it is up to the skill of the worker to apply the formulation to determine the specific amount of biologically active ingredient to be used for a particular application.

To convert the pesticide concentrate to a ready-to-use form, it is typically necessary to dilute with water to form an aqueous pesticide formulation. The ready-to-use aqueous pesticidal composition typically comprises 0.1 to 10% by weight, more preferably 0.5 to 5% by weight of the above pesticide concentrate, based on the weight of the composition, the remainder to 100% being typically water.

The precise degree of dilution of the pesticide concentrate necessary to produce a ready-to-use aqueous pesticide formulation will again depend upon the particular application itself, i.e., the target substrate to be treated, the area to be treated, etc. Again, it is up to the skill of the worker to apply the formulation to determine the specific amount of water needed to dilute the pesticide concentrate.

Finally, the present invention also describes a method of treating a target substrate, including contacting the target substrate with an aqueous pesticidal composition as described above.
