Abstract

The invention relates to a sterilization compound with metconazole and fenpyrazamine and purposes of the sterilization compound. The sterilization compound contains metconazole and fenpyrazamine, and the weight ratio of metconazole to fenpyrazamine is between 40 to 1 and 1 to 35. The compound can be applied to the control over diseases of flowers and plants or agricultural crops or the like. The compound is wide in application range, good in effect, low in residual and safe to human, livestock, the environment and the like.

Description

(1) Technical field [0001] The present invention relates to a bactericidal composition and its use, in particular to a bactericidal composition containing metconazole and fenpyrazone and its use, and is mainly used for the prevention and treatment of flower diseases. (2) Background technology [0002] As the planting of flowers becomes more and more widespread, various diseases and insect pests are also increasing. When the disease and insect condition index is serious, the output and quality of flowers are seriously affected. At present, the prevention and control of flower diseases mainly adopts "prevention first, prevention and control". "Supplement", and the prevention and treatment are mainly chemical agents. However, currently there are few chemical agents used to control flower diseases and insect pests in China, most of them are single agents, and most of them are not ideal. [0003] Metconazole (CAS No. 125116-23-6) is a C-14 demethylase inhibitor in ergosterol biosynthes...
