Abstract
Crop oil concentrates are disclosed which not only increase the herbicidal efficacy of herbicides from diverse chemical classes, but moreover assist in defeating the apparent antagonism which often arises when two or more herbicides are utilized together.
Claims34
A crop oil concentrate, comprising
- (a) from about 20 to about 90 weight percent of a lower alkanol ester of a fatty acid;
- containing from 4-22 carbon atoms.
- (b) from about 4 to about 40 weight percent of an anionic surfactant selected from the group consisting of the partial sulfate and phosphate esters and carboxylates of monohydroxylfunctional polyoxyalkylene ethers, and
- (c) from 2 to about 20 weight percent of a long chain carboxylic acid containing from about 10 to about 20 carbon atoms.
1 more element
A crop oil concentrate, comprising
- (a) from about 30 to about 80 weight percent of a lower alkanol ester of a fatty acid containing from 10 to about 20 carbon atoms;
- (b) from 4 to about 20 percent of an anionic surfactant selected from the group consisting of the partial sulfate and phosphate esters and carboxylates of monohydroxyl-functional polyoxyalkylene ethers having an average molecular weight of from about 600 to about 1200 Daltons;
- and
- (c) from 4 to about 16 weight percent of a long chain carboxylic acid having from 10 to about 20 carbon atoms.
1 more element
A crop oil concentrate, comprising
- (a) from about 35 to about 40 weight percent of a mixture which comprises the methyl esters of palmitic and oleic acids;
- (b) from about 6 to about 9 weight percent of an anionic surfactant which is a mixture of the partial phosphate esters of a hydroxylfunctional polyoxyalkylene ether initiated with a C.sub.10 -C.sub.14 aliphatic alcohol:
- (c) from about 3 to about 7 weight percent of an unsaturated long chain carboxylic acid selected from the group consisting of oleic acid, linoleic acid, and linolenic acid;
- and
- (d) from 40 to about 60 weight percent of a hydrocarbon component further comprising based on the weight of the hydrocarbon component, up to about 10 percent of a solvent soluble alcohol having from 5 to about 10 carbon atoms.
