Problems solved by technology

[0004] The use of spinetoram for the prevention and treatment of flea beetle has been reported in the literature, but due to the high cost of use of spinetoram and the tendency to produce drug resistance, there is an urgent need to develop new compound agents to reduce drug costs and improve Control effect
Although there is a compound formula of spinosad and pyridaben (CN105028423A), the compound drug is mainly used in whitefly, and there is no relevant report on the compound drug for preventing and treating flea beetle.

Abstract

The invention discloses an insecticidal composition. The active ingredients of the insecticidal composition comprise spinetoram and pyridaben, and a mass ratio of the spinetoram to pyridaben is 1:50 to 50:1. Compared with the prior art, the insecticidal composition disclosed by the invention has obvious effects of controlling phyllotreta striolata fabricius on brassicaceous vegetables, eggplant fruits, tobacco and other crops, and an obvious synergetic effect can be achieved, so that the pesticide dose can be reduced, the control cost is further reduced, the drug resistance can be delayed, and the environmental pollution can be reduced.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing spinosad and its application in controlling crop beetle flea beetle, belonging to the technical field of pesticides. Background technique [0002] Phyllotreta striolata (Fabricius) belongs to the Coleoptera Chrysanthemum family, and is an important pest that seriously damages Brassicaceae vegetables worldwide. The flea beetle is widely distributed in my country, and the algebra of occurrence is different in different regions, and there is a phenomenon of overlapping generations. Due to the strong reproductive ability of the insect, and the adults and larvae damage the above-ground plants and roots in the soil respectively, it is difficult to control. In recent years, it has been considered as one of the most difficult vegetable pests to control. At present, in Fujian, Guangdong, Taiwan and other places, the yellow flea beetle has replaced the ...
