[0117] Indoor Toxicity Test Example 1: Indoor Toxicity Test of Fluopyram and Propineb against Cucumber Powdery Mildew.

[0118] The original drug of Prosenb was dissolved in DMF, the original drug of Fluopyram was dissolved in acetone, and made into a 10,000 μg / ml mother solution, which was stored at 4°C until use.

[0119] The mass ratios of 60% fluopyram·propineb are 5%+55%, 6%+54%, 10%+50%, 15%+45% and 30%+30%, a total of 5 mixing combinations.

Abstract

The invention relates to a sterilization composite in the field of pesticide compounding, which is formed by compounding the active ingredient of the fluopyram and the sterilization active ingredient selected from any one of the propineb, the azoxystrobin and the methyl as the active ingredient. The weight percentage of the two active ingredients is 70-1:10-90, and the preferred weight percentage is 40-1:25-60. The weight percentage of the active ingredients of the sterilization composite is 1 to 90%, the preferred weight percentage is 15 to 70%, and the balance of the allowed and acceptable auxiliary ingredients in pesticide. The sterilization composite can be prepared into the emulsion, the micro emulsion, the emulsifiable concentrate, the suspending agent, the wettable powder and the water dispersible granule according to the existing methods. The sterilization composite of the invention is mainly used in the prevention and the cure of the diseases of the powdery mildew, the downy mildew, the rust disease, the leaf fungal diseases, the cladosporium cucumerinum, the rot and the like of the vegetables, the grains such as the wheat and the like, and the fruit trees caused by the germs.

Description

technical field [0001] The present invention relates to a synergistic bactericidal pesticide composition, in particular to a synergistic bactericidal composition compounded with fluopyram and any bactericidal active ingredient selected from propineb, azoxystrobin and kresoxim-methyl . Background technique [0002] Fluopyram, English common name fluopyram, chemical name is N-{2-[3-chloro-5-(trifluoromethyl)-2-pyridyl]ethyl-α,α,α-trifluoro-O -Toluamide}, a novel benzamide fungicide, inhibits mitochondrial respiration by blocking the electron transfer of succinate dehydrogenase in the respiratory chain. It is mainly used to control diseases caused by cyst fungi on broad-leaved crops. It has a good control effect on downy mildew and powdery mildew on vegetables such as cucumbers and zucchini, downy mildew on fruit trees and other diseases caused by pathogens. Its chemical structural formula is: [0003] [0004] Propineb (propineb), the molecular formula is (C 5 h 8 N ...
