Embodiment approach

[0019] In the following technical scheme, component A is selected from the biological pesticide lepimectin, and component B is selected from any one of buprofezin and pymetrozine.

[0020] In one of the technical solutions of the present invention, the insecticidal composition is an emulsion in water, and the weight percentage of the components is:

[0021]

[0022] The specific production steps of the emulsion in water are as follows: first, the original medicine A and B, solvent, emulsifier, and cosolvent are added together to dissolve into a uniform oil phase; Pesticide auxiliaries are mixed together to form a uniform water phase; while stirring at high speed in the reactor, add the oil phase to the water phase, slowly add water until the phase inversion point is reached, turn on the shearer for high-speed shearing, and add the remaining water , cut for about half an hour to form an oil-in-water emulsion. A water emulsion of the composition of the present invention can ...

Abstract

The invention relates to an insecticidal composition in the field of pesticide formulation, which comprises the active ingredients of biopesticide lepimectin and buprofezin or pymetrozine through blending, and the weight ratio of the two active ingredients is 0.1-50:75-1, preferably 0.1-30:40-10; and the total weight percent of the active ingredients in the insecticidal composition is 5%-90%, preferably 10%-50%, and the remaining ingredients are auxiliary ingredients allowable and acceptable in pesticide. In the existing method, the insecticidal composition can be prepared into emulsion in water, microemulsion, missible oil, suspending agent, wettable powder and water dispersible granules; and the insecticidal composition taking the biopesticide lepimectin and the buprofezin or the pymetrozine as the active ingredients has an obvious effect in preventing and treating lepidoptera insets such as plutella xylostella, beet armyworm, prodenia litura, cotton bollworm, rice stem borer, mealybug and the like, and homoptera suckingpests such as plant hopper, aphid, aleyrodid, leafhopper and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a high-efficiency and environment-friendly insecticidal composition containing biopesticide lepimectin and any one of buprofezin or pymetrozine. Background technique [0002] The biopesticide lepimectin is a derivative of milbemycin (milbemycin) A3 / A4 discovered by Sankyo Corporation of Japan. It is used as a new type of insecticide for vegetables and fruits such as cabbage, tomato, citrus, strawberry and grape, mainly to control Lepidoptera and Homoptera and other pests. The drug has the characteristics of high insecticidal activity, less dosage, safe for humans and animals, no environmental pollution, strong specificity, no harm to natural enemies, and not easy to produce resistance, etc. It can be used in rotation with abamectin insecticides, In case of abamectin resistance. Therefore, it is known as one of the most promising broad-spectrum, high-efficiency, ne...
