AI Technical Summary

Problems solved by technology

Not all pesticides can be mixed. For example, organosulfur and organophosphorus pesticides cannot be mixed with pesticides containing copper preparations, such as dithiocarbamate fungicides, 2,4-D salt herbicides and copper preparations. , lose activity due to complexation with copper ions, microbial source insecticides and systemic organophosphate insecticides cannot be mixed with fungicides, etc.
[0006] At present, there are few studies on the compounding of different types of pesticides such as insecticides and fungicides, and most of the existing studies are still at the level of tank mixing or simple combination. There is no synergy in the prevention

Abstract

The invention relates to the field of agriculture, in particular to an active ingredient composition, an insecticide sterilization composition containing difenoconazole and pymetrozine and application of the insecticide sterilization composition. According to the insecticide sterilization composition and the active ingredient composition containing difenoconazole and pymetrozine, the weight ratio of difenoconazole to pymetrozine is 100:1-1:100. The invention also relates to an insecticide sterilization composition containing the active ingredient composition and an agriculturally acceptable additive and / or carrier and a method and application of the active ingredient composition or the insecticide sterilization composition for prevention and control of agricultural pathogenic bacteria and / or agricultural pests.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to an active ingredient composition, in particular to an insecticidal and fungicidal composition containing difenoconazole and pymetrozine and its application. Background technique [0002] The prevention and control of agricultural diseases and insect pests has always been the most concerned and important issue in agricultural production. Crops are attacked by various diseases and insect pests almost throughout the growing season. For the control of crop diseases and insect pests, the current conventional practice is to apply fungicides when diseases occur, and to apply insecticides when pests occur, that is, the strategy of independent control of diseases and insect pests, which will undoubtedly increase the frequency of application. Therefore, there is a need to improve current medication habits. [0003] Difenoconazole (Difenoconazole, Cas.NO: 119446-68-3) is a broad-spectrum and hi...
