Abstract

The present invention discloses an insecticidal composition with azadirachtin and salix myrtillacea total saponins as active ingredients and a usage thereof, and belongs to the field of pest control in process of crop planting. The composition comprises the active ingredients of the azadirachtin and salix myrtillacea total saponins; the weight ratio of the azadirachtin to the salix myrtillacea total saponins is 1:(0.1-10); and most preferably, the weight ratio of the azadirachtin to the salix myrtillacea total saponins is 1:6.38. The composition is used for the pest control in agricultural production, and preferably used for controlling lepidopteran pests, particular for controlling plutella xylostella L. The salix myrtillacea total saponins and azadirachtin have extremely strong enhancingfunctions on drug effects each other, can greatly improve the control effects on agricultural pests, and have the effect far superior to that of the single use of the salix myrtillacea total saponinsor azadirachtin, can significantly reduce cost of pesticides and broadens the scope of the use.

Description

Technical field [0001] The invention belongs to the field of pest control during crop planting, and specifically relates to an insecticidal composition using azadirachtin and total saponin as active ingredients and its usage. Background technique [0002] Azadirachtin (Azadirachtin) is a class of highly active compounds isolated from Neem, which belongs to the tetracyclic triterpenes. The fruits, seeds, seed cores, branches, leaves, bark and sap of Neem all contain active substances. So far, more than 100 compounds have been found in Neem, and at least 70 compounds have biological activity, mainly from India. Azadirachtin, neemtriol and azadirachtin, etc., these extracts have anti-feeding effects on insects, interfere with oviposition, interfere with insect mutation, make them unable to metamorphose into adults, repel larvae and inhibit their growth to achieve insecticidal purposes. [0003] Azadirachtin has become a commonly used biological pesticide at this stage, and has been w...
