Problems solved by technology

However, long-term use of a single type of fungicide will cause different degrees of disease resistance and reduce the control effect
[0009] At present, for the prevention and control of diseases that are prone to resistance, the main method is to develop new pesticide ingredients that have no cross-resistance with existing pesticide varieties or to compound the existing pesticide varieties. The cycle is long, and the current development speed is far behind the speed of drug resistance

Abstract

The invention relates to a sterilization composition containing phenamacril and metrafenone. The weight ratio of phenamacril to metrafenone is (1-80):(80-1). The sterilization composition containing phenamacril and metrafenone can prevent and control wheat scab and wheat powdery mildew at the same time.

Description

[0001] Technical field: [0002] The invention belongs to the field of agricultural fungicides, and in particular relates to a fungicidal composition containing cyclostrobin and metrafenone and its application for preventing and treating wheat diseases. [0003] Background technique: [0004] Phenamacril, test number: JS399-19, chemical name: ethyl 2-cyano-3-amino-3-phenylacrylate. Synthesized by Jiangsu Provincial Pesticide Research Institute, it is a new type of fungicide with independent intellectual property rights in my country. The agent is resistant to rain erosion, has good systemic penetration performance and excellent protective and therapeutic effects. Cyanostystrobin has high biological activity against Fusarium graminearum, Fusarium moniliforme, and Fusarium oxysporum of the Fusarium genus, and is suitable for the treatment of crop diseases such as wheat head blight, rice bakanae disease, and watermelon wilt. Effective prevention and control. [0005] Metrafenon...
