In above-mentioned formula, described auxiliary agent is emulsifier and thickener, and wherein emulsifier is 4% ~ 25% of all material gross masses, and thickener consumption is 1% ~ 5% of all material gross masses; Described emulsifier model is 2201 or 4203, and thickener is dextrin or xanthans.
The drug administration process for the treatment of rice blast provided by the invention is watered spraying, and the ratio that medicine is watered is 1: 1000.
Treatment rice blast medicine feature of the present invention is: good drug efficacy, and than the medicament indoor biometrics better effects if of current treatment rice blast, its bacteriostasis rate reaches 100%, and field trial is verified, its preventive effect reaches more than 90%, and not easily produces resistance, and reagent cost is lower.Be applicable to paddy rice control rice blast.
Treatment rice blast medicine of the present invention is through the plant protection unit test of Meitan County, Guizhou Province bureau of agriculture, and the control efficiency of rice blast is 80.25% ~ 83.12%, increasing production of rice 12.56% ~ 17.13%; Test people thinks that this medicine has diseases prevention and the effect promoting plant strain growth, in rice blast is prevented and treated, by inferring that the control efficiency being used for seedling leaf pest and leaf pest is in earlier stage better.
