Embodiment 3

[0047] The contents of the following substances are all percentages by weight: 20% copper succinate, 1% thiamethoxam, 6% sodium lauryl polyoxyethylene ether sulfate, 4% pull-off powder, 1% xanthan gum, Isothiazolinone 0.2%, C 10-20 Saturated fatty acid compound 0.1%, sorbitol 3%, deionized water make up to 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare a 21% copper succinate fatty acid thiamethondone suspension concentrate.

[0048] The above-mentioned 21% copper succinate fatty acid · thiamethondone suspension concentrate was used to control cucumber downy mildew. As can be seen from Table 3, 30 days E-E 0 The value is 22.95%, which shows that the combination of copper succinate and thiamethonin has a synergistic effect on cucumber downy mildew. At the same time, no phytotoxicity to cucumber was found after applying 21% copper succinate-thiamethondone suspension concentrate ...

Abstract

The invention discloses a pesticide composition containing copper succinate and benziothiazolinone. The pesticide composition is prepared from effective active ingredients of copper succinate and benziothiazolinone, wherein the weight ratio of copper succinate to benziothiazolinone is (40 to 1) to (1 to 1). The pesticide composition provided by the invention has the advantages of excellent preventing and controlling effects on diseases such as downy mildew, anthracnose, bacterial angular leaf spot, canker and soft rot disease, long persistence period and safety for crops. The compound of copper succinate and benziothiazolinone has a remarkable synergistic effect; the use amount of the pesticide can be reduced, the use cost is reduced, the pollution to the environment is reduced, pesticideresistance of pathogen is delayed and the service life of the pesticide is prolonged.

Description

technical field [0001] The invention relates to a pesticide composition and its application field, in particular to a binary compound compounded with copper succinate and thiamethoxam as effective active ingredients, which is mainly used in the prevention and control of crop diseases. Background technique [0002] Copper succinate is an organocopper fungicide. The mechanism of action is that copper ions exchange with cations on the surface of pathogenic bacteria membranes to coagulate the proteins on the pathogenic bacteria cell membranes. its activity. [0003] Thiemadone is a high-efficiency, low-toxicity, broad-spectrum fungicide. Its mechanism of action is to combine with anions on the surface of bacteria and mold cell membranes or react with sulfhydryl groups to destroy the synthesis system of proteins and cell membranes, thereby inhibiting bacteria and molds. Reproduction, interfering with the metabolism of pathogenic bacteria cells, making them physiologically disord...
