Abstract

The invention provides a additive combination with synergism function of pesticide, the combination comprises the following components by weight percentage: 10 to 20 percent of methyl hexadecanoate, 5 to 10 percent of methyl stearate, 20-40 percent of 9-cis-octadecenoic acid methyl ester, 20 to 40 percent of 9, 12-cis-octadecadienoic acid methyl ester, 10 to 20 percent of 9-cis-11-trans-13-trans-jecoric acid methyl ester, 10 to 20 percent of benzene ethylphenol polyoxyethylene ether, 1 to 5 percent of calcium alkyl benzene sulfonate. The additive combination with synergism function of pesticide has the advantages of convenient raw material source, no pollution to environment, convenient preparation and application, and herbicidal efficacy of herbicide can be improved significantly.

Description

technical field [0001] The invention relates to an adjuvant composition for improving the herbicidal efficacy of chemical herbicides. Background technique [0002] Herbicides are widely used pesticides in modern agriculture, and have been widely used in the production of various crops such as rice, wheat, rape, corn and vegetables. The main economic and technical indicators for evaluating the function of herbicides are to maximize the efficacy of killing weeds at a certain dose and to minimize the damage to the protected crops. How to improve the efficacy of chemical herbicides has always been a subject of great concern. [0003] At present, for atrazine herbicide and nicosulfuron herbicide, its conventional practice is to select suitable auxiliary materials, such as surfactants, etc., mix it with herbicide, and prepare it into water suspension (English abbreviation is SC ), to disperse and suspend the water-insoluble herbicide in water to improve the efficacy of the herbi...
