Problems solved by technology

[0004] Enoxstrobin has good activity against almost all fungal diseases, but it is easy to produce drug resistance and high cost when used alone, which is not conducive to large-scale promotion and use; carbendazim and thiophanate-methyl have a wide bactericidal spectrum The cost is low, but due to the increase in resistance in recent years, the control effect is not ideal when used alone, the effect of expanding the bactericidal spectrum and reducing costs

Abstract

The invention provides a pesticide composite containing enestroburin. The pesticide composite comprises active components A and B, wherein the active component A is enestroburin and the active component B is one of carbendazin and thiophanate-methyl, and the ratio of the active component A to the active component B in parts by weight is 1:64-16:1. The pesticide composite can be prepared into wettable powder, water dispersible granule, suspending agent, suspending emulsifier and the like and has an ideal prevention effect on crop diseases such as powdery mildew, anthracnose, phytophthora blight, downy mildew, leaf spot, damping off, banded sclerotial blight, rice blast and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition compounded with erythoxystrobin and carbendazim or thiophanate-methyl, which is used for the prevention and treatment of plant diseases. technical background [0002] Enostroburin, molecular formula: C 22 h 27 ClNO 4 , chemical name: methyl α-[[[[4-(4-chlorophenyl)-but-3-en-2-yl-]imino]methyl]phenyl-β-methoxyacrylate. [0003] The broad-spectrum fungicides of erythoxystrobin are a new class of pesticides successfully developed from the natural product Strobilurins as fungicide lead compounds, belonging to the methoxyacrylate fungicides. The principle of action of this type of agent is to inhibit the respiration of fungal mitochondria, and inhibit the potential transmission of mitochondria through the combination of the Q0 part of the cytochrome bc1 complex, thereby destroying the energy synthesis of pathogenic bacteria and playing a bacte...
