Abstract

The invention is concerned with the enganced insect disinfestations combination, includes the as the active constituent, fipronil: spinosad = 1:100 to 100:1.

Description

technical field [0001] The invention relates to a synergistic insecticide composition, which contains a combination of fipronil and spinosyn as active ingredients, and belongs to a novel, high-efficiency, and low-toxic insecticide formula. Background technique [0002] The loss of crop yield due to pests and diseases of crops is immeasurable, so 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. In addition, the current agricultural and forestry production still uses chemical pesticides as the main species, and many chemical pesticides remain in the environment, causing pollution to the environment. Therefore, more efficie...
