Abstract

The invention belongs to the field of pesticides and in particular relates to a sterilization composition. The sterilization composition comprises active compounds, namely zinc thiazole and biphenyl pyrazine amino, wherein the weight ratio of the zinc thiazole to the biphenyl pyrazine amino is 1 to (0.01-100). The sterilization composition provided by the invention has remarkable synergistic interaction, the characteristics that the zinc thiazole has an efficient bacterial disease control effect and the biphenyl pyrazine amino has a universal treatment effect on fungal diseases, and a good protection property of the sterilization composition, can be brought into sufficient play, and meanwhile a remarkable synergism effect is achieved; and not only can the antibacterial or bacteriostatic effect be improved, but also prevention and treatment spectrums are widened, a very good prevention or treatment effect can be achieved for bacterial diseases and fungal diseases of crops, medicine administration times are reduced, the environment burden is alleviated, and thus an effect of chief prevention and comprehensive prevention and treatment are achieved.

Description

technical field [0001] The invention relates to a fungicidal composition, in particular to a fungicidal composition containing Zinc thiazole and Pyraziflumid for preventing and controlling plant diseases and promoting the healthy growth of crops. Background technique [0002] It is known that plants are attacked by bacteria, fungi, viruses and nematodes, among which bacteria and fungi are particularly harmful and pose a great threat to plant growth, breeding, storage and transportation. The fungicidal active compounds for controlling such diseases mainly include triazoles, methoxyacrylates, pyrroles, pyrimidines, amides, etc. However, in most cases, their plant tolerance and bactericidal activity cannot fully meet the needs of agricultural production, and the target of a single compound is relatively single, and it is easy to produce drug resistance, which will lead to an increase in the amount of pesticides used, and the increase in pesticide residues will further promote d...
