Abstract

A composite insecticide features that it contains methylamino abamectin benzoate and nimbin in the Wt ratio of (0.001-20):(0.01-80). Its advantages are broad spectrum and high effect.

Description

【Technical field】 [0001] The invention relates to an insecticidal composition, which contains emamectin benzoate and azadirachtin as active components. 【Background technique】 [0002] The loss of crop yield due to pests and diseases of crops is immeasurable. Therefore, it is necessary to apply a large amount of pesticides for pest control every year to recover the loss of crop yield. In recent years, pests have become more and more harmful to crops such as rice, fruit trees, vegetables, flowers and various economic crops, and due to the abuse of pesticides, pests have become more and more resistant to pesticides, resulting in pest control effects decrease year by year. Therefore, there is still a need for pesticide varieties with better pest control effects. [0003] Emamectin benzoate (emamectin benzoate) is a new type of high-efficiency semi-synthetic antibiotic insecticide and acaricide synthesized from the fermentation product avermectin B1. Residue, pollution-free an...
