Problems solved by technology

[0005] The main measure to solve the resistance of agricultural pests is to screen the active ingredients of pesticides with different mechanisms of action for compounding. It is against this background that the inventors of the present application obtained metarhizine through a large number of indoor activity determinations and field efficacy tests. The insecticidal composition compounded with spirotetramat, at present, there is no relevant report about the compounding of metarhizalin and spirotetramat

Abstract

The inventin discloses an insecticidal composition. Active ingredients of the insecticidal composition at least comprise destruxins and spirotetramat; the weight ratio of the destruxins to the spirotetramat is 1: 15-15: 1, and is 1: 10-1: 1 preferably. Prevention and control of the insecticidal composition on crop pests in the proportional region show a certain synergetic effect. The insecticidal composition can be prepared into an optional dosage suitable for agricultural production, includes but not limited to any one of emulsifiable concentrate, wettable powder, water dispersible granules, suspension agent, aqueous emulsion, microemulsion and a suspended emulsion agent, and is particularly suitable for preventing and controlling pests such as aleyrodid, aphid, phylloxera, thrips and beetles.

Description

technical field [0001] The invention belongs to the field of agricultural pest control, and specifically relates to an insecticidal composition containing metarhizalin and spirotetramat, the insecticidal composition is especially suitable for controlling various piercing-sucking mouthpart pests, such as Whiteflies, aphids, psyllids, thrips, beetles, etc. Background technique [0002] Bemisia tabaci is an important worldwide pest. After the 1970s, with the emergence of type B Bemisia tabaci, the harm of Bemisia tabaci to field crops, vegetables and flowers has become increasingly serious, especially in recent years, Bemisia tabaci have been breaking out in succession all over the world. Bemisia tabaci has been breaking out successively in different regions of my country since the early 1990s, especially seriously damaging crops such as cucumber, tomato, eggplant, and melon, and the damage rate to crops is as high as 70% or more. Bemisia tabaci has the characteristics of sma...
