Problems solved by technology

Herbicides are organic compounds widely used in existing farmlands, orchards, flower nurseries, etc. to eliminate or inhibit plant growth, such as glyphosate, glufosinate, 2,4-D, etc. The solubility in water is good, so it is easy to be leached by rainwater during use. The existing rain-resistant additives usually use high-molecular polymers or vegetable oils and mineral oils. Because of their poor water solubility, they are used in water-soluble Herbicides do not work very well, such as:

Abstract

The invention discloses a rainwash resistant pesticide adjuvant composition and application thereof. The rainwash resistant pesticide adjuvant composition comprises, by weight, 1-10% of polysaccharide, 5-20% of polyquaternium, 10-40% of alkyl-polyoxyethylene ester, 10-20% of emulsifier and the balance being solvents. The pesticide adjuvant can be used as a spray additive of herbicides, has excellent hydrophilcity, and has good rainwash resistance function to the herbicides, especially the water-soluble herbicides.

Description

technical field [0001] The invention relates to a rainwater scouring-resistant pesticide adjuvant composition and its application, in particular to a rainwater scouring-resistant auxiliary for herbicides and its application, and belongs to the technical field of pesticides. Background technique [0002] The reduction of application is a very important direction of modern pesticide research, and the use of spray adjuvants is one of the important ways to achieve the reduction of pesticide application and the increase of efficiency. After the pesticide is sprayed, if it rains in a short period of time, some active ingredients of the pesticide on the target surface will be lost due to the erosion of the rain, resulting in a decrease in the control effect. influences. Herbicides are organic compounds widely used in existing farmlands, orchards, flower nurseries, etc. to eliminate or inhibit plant growth, such as glyphosate, glufosinate, 2,4-D, etc. The solubility in water is go...
