Abstract

The invention discloses a pesticide composition containing fluconazole hydroxylamine and prochloraz and application thereof. The pesticide composition comprises effective components; the effective components are fluconazole hydroxylamine and prochloraz; the mass ratio of fluconazole hydroxylamine to prochloraz is 20:1 to 1:20. The invention further discloses the application of the pesticide composition containing fluconazole hydroxylamine and prochloraz to the treatment of fusarium head blight. The pesticide composition disclosed by the invention has the benefits that the respective potential drug resistance risk of gibberella zeae to fluconazole hydroxylamine and prochloraz is reduced; after fluconazole hydroxylamine and prochloraz are combined, an obvious synergistic effect exists between fluconazole hydroxylamine and prochloraz; the effect on prevention and treatment of the fusarium head blight is significant.

Description

technical field [0001] The invention relates to the prevention and treatment of wheat diseases, in particular to a pesticide composition containing flufenapyramide and prochloraz and an application thereof. Background technique [0002] Wheat scab (Fusarium HeadBlight), caused by the fungus Gibberella zeae, is a common disease worldwide. Wheat head blight not only causes serious economic losses, but also seriously threatens food safety due to the production of mycotoxins. Due to the generally poor disease resistance of wheat varieties, chemical control has always been the key to reducing the occurrence of head blight. In China, since the 1970s, carbendazim has been used in the control of wheat head blight for more than 40 years. [0003] Since the carbendazim-resistant strain of Gibberella zease was discovered in Haining City, Zhejiang Province in 1992, carbendazim-resistant populations have occurred and spread to varying degrees in Jiangsu Province, Shanghai City and Anhu...
