Abstract

The invention belongs to the field of biotic insecticides and relates to a microbial pesticide synergist. The main ingredient of the synergist is camptothecin or a derivative thereof. The invention relates to two microbial pesticides containing the synergist at the same time, namely a microbial pesticide containing bacillus thuringiensis and the camptothecin / camptothecin derivative, and a microbial pesticide containing baculovirus and the camptothecin / camptothecin derivative. The synergist can effectively improve the pest killing effect of the bacillus thuringiensis or baculovirus pesticide, enhance the pesticide effect and reduce the dosage of the microbial pesticide while ensuring the same pest preventing and controlling effect; moreover, the active ingredient camptothecin of the synergist is a plant-originated substance which is safe for people and livestock and natural enemies of the pests, can slow down the pesticide resistance of the pests to the microbial pesticide and is easy to degrade without residue; and the synergist is suitable to be used as an environmental-friendly microbial pesticide synergist and has great significance for popularization and application of the microbial pesticide.

Description

technical field [0001] The invention belongs to the field of biopesticides and applications thereof, and relates to a microbial pesticide synergist and a biopesticide containing the synergist. Background technique [0002] Biopesticide refers to a type of pesticide preparation that uses living organisms or their metabolites to control pests, germs, weeds, nematodes, rodents and other harmful organisms. Biological pesticides include microbial-derived pesticides, plant-derived pesticides, animal-derived pesticides and genetically modified Compared with chemical pesticides, biological pesticides have the following advantages: 1) strong selectivity, relatively safe for humans, animals and various beneficial organisms, and protect natural enemies. 2) It has little impact on the ecological environment, and 3) it can induce pest epidemics and the like. [0003] Microbial pesticides are an important part of biopesticides. They are made from microbial groups whose metabolites or mic...
