Crop oil concentrates are disclosed which increase the herbicidal efficacy of herbicides from diverse chemical classes. These crop oil concentrates comprise an anionic polyoxyalkylene surfactant or salt thereof, an adjuvant which is exclusively a fatty acid or its ester, and a hydrocarbon component. These crop oil concentrates are especially effective with cyclohexenone and triketone herbicides and growth regulators.

Crop oil concentrates

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.

Antagonism defeating crop oil concentrates

Ready-to-Dilute (RTD) herbicide formulations containing crop oil type adjuvants are disclosed which may be added as is to water to form a tank mix for herbicide application. The formulations are storage stable for extended periods, provide for rapid self-emulsification, form a stable tank mix, and moreover provide equal or better herbicidal efficiency than tank mixes containing commercially available standard crop oils and standard herbicide formulations.

Ready to dilute adjuvant-containing postemergent herbicide formulations

Herbicide adjuvants are disclosed with enhance the effectiveness of a broad spectrum of postemergent herbicides. These adjuvants preferably contain a low foaming nonionic surfactant, an anionic surfactant, a lower alkanol ester of a fatty acid, and a hydrocarbon oil component.
