A kind of insecticide composition containing cyantraniliprole and lambda-cyhalothrin

Abstract

The invention discloses an insecticide composition containing cyantraniliprole and lambda-cyhalothrin, which contains 15%-23% of cyantraniliprole and 3%-15% of lambda-cyhalothrin, The balance is additives and oil fillers, and the percentage concentration is weight percentage. The dosage form of the insecticidal composition is preferably a dispersible oil suspension concentrate, and the manufacturing process is: a combination of grinding and "post-emulsification dispersion", that is, preparing lambda-cyhalothrin into an oil phase similar to emulsifiable concentrate and adding it to the traditional grinding method. In the chlorofluraniliprole dispersible oil suspension concentrate, it is emulsified and dispersed uniformly by a high-shear disperser; the dispersible oil suspension concentrate of the insecticide composition is easy to produce resistance to lepidoptera such as diamondback moth. It has excellent pest control effect, good crop compatibility, quick effect and long-lasting effect, and low environmental irritation during production and use. It can be used for the control of pesticide resistance of diamondback moth.

Problems solved by technology

[0009] Plutella xylostella is a worldwide important pest that eats and damages cruciferous vegetables, often causing serious losses to agricultural production

Since its resistance to insecticides was first reported in 1953, it has been found in Shanghai, Guangdong, Hainan, Shandong and other areas of China that diamondback moth can regulate the growth of organophosphorus, carbamate, pyrethroid and benzoylphenylurea insects. More than 50 kinds of insecticides such as insecticides have developed resistance; when the diamondback moth is seriously damaged, even if the dosage is increased, the damage cannot be effectively controlled; this makes safe, environmentally friendly and efficient diamondback moth control agents very rare, and many Sometimes farmers have to use highly toxic or even highly toxic pesticides to control

On the one hand, this will increase the exposure risk of farmers and users when using highly toxic and highly toxic pesticides, which will endanger their health; on the other hand, the resulting problem of highly toxic and highly toxic pesticide residues will also bring serious hidden dangers to food safety
