Problems solved by technology

Thiobacterium copper is an organic copper fungicide with a unique mechanism of action. Both thiadiazole and copper ions work. It has a dual bactericidal mechanism and good systemic conductivity. It has unique therapeutic and protective effects. The therapeutic effect is greater than the protective effect. Effect; because of the long period of time it is used to prevent and control bacterial diseases, the diseases have a certain resistance to it, and the control effect is reduced
At the same time, with the adjustment of the planting structure, the occurrence of bacterial diseases is relatively serious, and there is a lack of effective agents for preventing and treating bacterial diseases.

Abstract

The invention provides a compound composition, in particular to a compound composition containing 2-p-fluorophenyl-5-methylsulfonyl-1,3,4-oxadiazole and thiodiazole copper, wherein the weight ratio of 2-p-fluorophenyl-5-methylsulfonyl-1,3,4-oxadiazole to thiodiazole copper is (20-1):(1-40). Compared with each of 2-p-fluorophenyl-5-methylsulfonyl-1,3,4-oxadiazole and thiodiazole copper, the compound composition provided by the invention has an obvious synergistic effect on bacterial diseases of crops, improves the bactericidal effect, reduces pesticide cost, environmental pollution and pesticide residue, and is conductive to overcoming the generation of pesticide resistance. The compound composition provided by the invention has no obvious adverse effect on tested crops, ensures normal leaf color, growth and the like, has high safety, meets the safety requirements of pesticide preparations and plays a favorable control role on bacterial diseases of crops.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a composition compounded with two bactericidal active ingredients and a preparation thereof. Background technique [0002] Thiobacterium copper is an agent for preventing and treating bacterial diseases invented and created by Zhejiang Longwan Chemical Co., Ltd. Its invention patent number is ZL99113411.7, and its molecular formula is C 4 h 4 N 6 S 4 Cu. Thiobacterium copper is an organic copper fungicide with a unique mechanism of action. Both thiadiazole and copper ions work. It has a dual bactericidal mechanism and good systemic conductivity. It has unique therapeutic and protective effects. The therapeutic effect is greater than the protective effect. Effect: Because of the long period of use for the prevention and treatment of bacterial diseases, the diseases have a certain resistance to it, and the control effect decreases. At the same time, with the adjustment of t...
