Abstract

The invention discloses application of a fungicidal composition to prevention and treatment of crop gibberellic diseases and gibberellic disease mycotoxin pollution. Active components of the fungicidal composition contain 2-cyano-3-phenyl-3-amino ethyl acrylate and prothioconazole. In the fungicidal composition disclosed by the invention, the 2-cyano-3-phenyl-3-amino ethyl acrylate and the prothioconazole have the obvious synergistic effect; components are reasonable and the fungicidal composition has treatment and protection effects and a good fungicidal effect; the prevention effect can be up to about 95%; the medicine utilization time is reduced and the medicine utilization cost is low; the formation of gibberellic disease mycotoxins can also be obviously inhibited; the content of DON (Deoxynivalenol) toxins in wheat grains is only 0.18-0.29mg / kg.

Description

technical field [0001] The invention relates to the technical field of use of fungicides, in particular to the application of a fungicide composition in preventing and controlling crop scab and scab toxin pollution. Background technique [0002] Wheat is an important food crop in my country. Scab is an important disease that endangers wheat production and seriously affects the yield and quality of wheat. Wheat scab is caused by a variety of Fusarium, Fusarium graminearum and Fusarium graminearum (Fusarium asiaticum) is the main pathogenic fungus of scab in my country, which can be damaged from seedlings to heading, and the most serious impact is ear rot, which seriously affects the yield of wheat. [0003] Fusarium rubella can also produce toxin - deoxynivalenol (DON), deoxynivalenol can not only pollute crops, but also contaminate food products, with strong toxicity, second only to Aspergillus flavus white. Deoxynivalenol can be quickly and effectively absorbed in the body...
