AI Technical Summary

Problems solved by technology

For example, the production cost of sulfoxaflor preparations in the field is relatively high. In addition, sulfoxaflor is prone to photolysis and hydrolysis in the natural environment, so the efficacy and persistence of sulfoxaflor are limited. The effect of pest control has been affected to a certain extent
Cyclopyrid, as a chemical pesticide, currently has a good control effect on pests. However, in order to improve the control effect of pesticides on pests, farmers continue to increase the dosage of pesticides. In addition, pests are prone to develop resistance to pesticides.

Abstract

The invention relates to preparation of a pesticide formulation for preventing and controlling bemisia tabaci, belonging to the technical field of pesticides. The sulfoxaflor-containing pesticide formulation for preventing and controlling bemisia tabaci comprises the following ingredients by weight percentage: 0.1-40.0% of sulfoxaflor and 0.1-40.0% of cycloxaprid, which are effective ingredients, and the balance of auxiliary agents. The pesticide formulation is in a form of microemulsion, emulsion in water or suspension concentrate. The pesticide formulation is in the form of microemulsion, emulsion in water or suspension concentrate prepared from the main ingredients and the auxiliary agents, can thoroughly kill the bemisia tabaci in a high-efficiency manner, has low pollution to the environment and low production cost, and is suitable for chemical prevention of the bemisia tabaci.

Description

technical field [0001] The invention relates to the preparation of a pesticide preparation for controlling Bemisia tabaci, belonging to the technical field of pesticide preparation. Background technique [0002] Bemisia tabaci ( Bemisia tabaci (Gennadius)) belongs to the small whitefly genus of the family Whitefly of the order Homoptera. Since it was discovered on Greek tobacco in 1889, it has been distributed on all lands in the world except Antarctica, with as many as 600 species of host plants, and has become a worldwide It is an important pest on vegetables, commercial crops and garden flowers, and its harm is increasing day by day. Bemisia tabaci is one of the main pests on tobacco. It not only punctures tobacco leaf juice, secretes honeydew, induces soot, and causes direct loss of nutrients in tobacco leaves. More importantly, it spreads a variety of plant viruses, seriously affecting the yield and quality of tobacco leaves. Quality, the harm caused by the virus dise...
