Abstract

Described herein are compositions comprising a nematicide intermixed with lecithin and a co-surfactant that form stable dispersions in water. Also disclosed are methods of controlling nematodes in soil by application of such compositions.

First claim

What is claimed is:

1. A composition in the form of an emulsion comprising:
corn oil;
a sugar alcohol; and
a lecithin-co-surfactant blend comprising 50-90% lecithin and a co-surfactant, the co-surfactant having a hydrophilic-lipophilic balance of between 12 and 16 and the blend having a hydrophilic-lipophilic balance value of between 10 and 18.

2. The composition of claim 1 , wherein the co-surfactant is selected from the group consisting of sorbitan monostearate, polyoxyethylene ester of rosin, polyoxyethylene dodecyl mono ether, polyoxyethylene-polyoxypropylene block copolymer, polyoxyethylene monolaurate, polyoxyethylene monohexadecyl ether, polyoxyethylene monooleate, polyoxyethylene mono(cis-9-octadecenyl)ether, polyoxyethylene monostearate, polyoxyethylene monooctadecyl ether, polyoxyethylene dioleate, polyoxyethylene distearate, polyoxyethylene sorbitan monolaurate polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitan monopalmitate, polyoxyethylene sorbitan monostearate, polyoxyethylene sorbitan trioleate, polyoxyethylene sorbitan tristearate, polyglycerol ester of oleic acid, polyoxyethylene sorbitol hexastearate, polyoxyethylene monotetradecyl ether, polyoxyethylene sorbitol hexaoleate, hexaester with sorbitol, ethoxylated castor oil, ethoxylated soybean oil, ethoxylated polyoxyethylene sorbitol tetraoleate, fatty acids, tall-oil, and combinations of any thereof.

3. The composition of claim 1 , wherein the lecithin is selected from the group consisting of fluid lecithin, deoiled lecithin, crude lecithin, acetylated lecithin, hydroxylated lecithin, and combinations of any thereof.

4. The composition of claim 1 , wherein the sugar alcohol is selected from the group consisting of sorbitol, glycerol, ethylene glycol, propylene glycol, and combinations of any thereof.

5. The composition of claim 1 , further comprising an alcohol.
