Abstract

The invention discloses an insecticidal composition containing beauveria bassiana and spinetoram. The insecticidal composition is characterized by being prepared from an effective component A, i.e., the beauveria bassiana, and an effective component B, i.e., the spinetoram, wherein the quantity of the effective component A, i.e., the beauveria bassiana, is 5 to 40 billion spores per gram; the content of the effective component B, i.e., the spinetoram, is 5 percent to 50 percent; the preferable quantity of the effective component A, i.e., the beauveria bassiana, is 20 to 40 billion spores per gram; the preferable content of the effective component B, i.e., the spinetoram, is 10 percent to 30 percent. The insecticidal composition disclosed by the invention has a remarkable synergetic effect;the dosage of pesticide can be reduced, the residual amount of the pesticide on crops is reduced and the environment pollution is alleviated; the insecticidal composition is safe to human and livestock and has good environmental compatibility, and insect pests do not easily have drug resistance. The insecticidal composition has a function of preventing and controlling lepidoptera pests and especially has a remarkable prevention and control effect on cabbage/plutella xylostella, corn/ostrinia nubilalis and paddy rice/cnaphalocrocis medinalis.

Description

technical field [0001] The invention relates to an insecticidal composition containing Beauveria bassiana and spinosad, belonging to the technical field of pesticides. Background technique [0002] Cabbage is also known as head cabbage, cabbage, cabbage, and cabbage. It is one of the best vegetables recommended by the World Health Organization, and is also known as a natural "stomach". The vitamin K1 and vitamin U contained in it can not only resist gastric ulcer, protect and repair gastric mucosal tissue, but also keep gastric cells active and vigorous, reducing the chance of disease. Plutella xylostella, belonging to the family Lepidoptera Plutella, is an important worldwide pest that damages cruciferous vegetables, often causing devastating damage to the production of cruciferous vegetables. Chemical pesticides are the main control measures for Plutella xylostella. The long-term use and abuse of a large number of chemical insecticides has led to continuous improvement o...
