Abstract

The invention discloses a sterilizing composition containing fludioxonil and metalaxyl, a preparation method thereof, and an application thereof. The sterilizing composition is characterized in that: the sterilizing composition comprises fludioxonil, metalaxyl, and other auxiliary agents. A weight ratio of fludioxonil to metalaxyl is 70:1-1:60. The sterilizing composition can be used for controlling paddy rice blast. The sterilizing composition has advantages of low cost and good effect. No report about fludioxonil and metalaxyl blending is found home or abroad. Therefore, the invention is provided.

Description

technical field [0001] The invention belongs to the field of pesticide compounding, and relates to a bactericidal composition, in particular to a bactericidal composition with fludioxonil and metalaxyl as main active components and the application of the bactericidal composition in agricultural production. Background technique [0002] The application of chemical agents is the most effective means of controlling plant diseases. However, long-term continuous high-dose application of a single chemical fungicide is likely to cause problems such as drug residues, environmental pollution, and the development of drug-resistant fungi. Reasonable compounding or mixing of chemical fungicides has positive effects such as expanding the bactericidal spectrum, improving the control effect, prolonging the application period, reducing the dosage, reducing the injury, reducing the residue, and delaying the occurrence and development of fungal drug resistance and drug resistance. Characteri...
