Problems solved by technology

However, due to the promotion and use in my country for nearly 40 years, the long-term and large-scale use has resulted in serious resistance to the field efficacy of eubacazole, decreased biological activity, and unsatisfactory disease control effects.
Even if a better new agent is developed, if it is used for a long time, the resistance of the disease will be strengthened, resulting in a decline in the control effect

Abstract

The invention discloses a compound composition and a preparation thereof. The compound composition comprises two active ingredients, the first active ingredient is methylsulfonyl azole, and the second active ingredient is bismerthiazol, wherein the weight ratio of the first active ingredient to the second active ingredient is (20-1):(1-40); and the chemical name of methylsulfonyl azole is 2-(4-fluorophenyl)-5-methylsulfonyl-1,3,4-oxadiazole. The compound composition can be used for effectively preventing and controlling bacterial diseases, and has a remarkable synergetic effect relatively to a single agent, the using amount and application times of pesticide can be reduced, the drug resistance of pathogenic bacteria can be retarded, and the prevention and control effect can be improved. Methylsulfonyl azole and bismerthiazol have high safety, and can be used for better guaranteeing safe production of agriculture and protecting the ecological environment.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and relates to a compound pesticide containing mesycloconazole and ebuconazole, its preparation and application. Background technique [0002] With the change of planting structure, the occurrence of bacterial diseases of crops is increasing, and the types of pesticides for the control of bacterial diseases are limited. Ebacazole is the leading product for the control of bacterial diseases, and it is the most commonly recommended pesticide for the control of bacterial diseases in rice. Eccumazole is a systemic therapeutic fungicide independently developed in my country. It belongs to the new thiazole class of drugs, also known as Yeqingshuang and Thiacumazole. Its molecular formula is: C 5 h 6 N 6 S 4 . Yebazole has systemic, therapeutic and conductive effects, and is mainly used to prevent and control plant bacterial diseases. It has good control effects on rice bacterial blight,...
