Thifluzamide-containing composite bacteriacide

Abstract

The invention discloses a thifluzamide-containing composite bacteriacide, which comprises two active ingredients, namely thifluzamide and fludioxonil, ethirimol or epoxiconazole, wherein a mass ratio of the thifluzamide to the fludioxonil, the ethirimol or the epoxiconazole is (30-1):(1-30); and the thifluzamide and the fludioxonil, the ethirimol or the epoxiconazole are mixed with a dispersing agent, a wetting agent, an antifreeze agent and a thickening agent to prepare a suspending agent and aqueous dispersion granules. The thifluzamide-containing composite bacteriacide has the advantages that: various ingredients in the composite bacteriacide are different in effect mechanisms and are synergistic mutually and the medicinal resistance of germs is reduced, so the bactericidal effect of the composition is obviously higher than that of independent component; and the composite bacteriacide has the synergistic effect and is wide in a bactericidal spectrum. The thifluzamide-containing composite bacteriacide can be used for preventing and controlling various diseases of various crops, has the good inhibitory effect on downy mildew, gray mold, banded sclerotial blight and powdery mildew, and can be used for crops such as bananas, watermelons, cucumbers, tomatoes, chili, paddy, wheat, tangerines and the like.

Description

technical field [0001] The invention relates to a pesticide, in particular to a composite bactericide containing thiaflufen. Background technique [0002] In recent years, due to single drug use and other unscientific drug use methods, a variety of crop pathogens such as powdery mildew, downy mildew, and Phytophthora have developed resistance, which has become a major problem in chemical control. Due to the resistance of the bacteria, frequent application of pesticides, increased burden on farmers and increased environmental pollution. In order to meet people's increasingly higher requirements for food safety and living environment, to delay the emergence of pathogenic bacteria resistance, and to effectively utilize existing pesticide resources, it is of great significance to develop new pesticide compound varieties. [0003] Thifluzamide is an amide compound and a succinate dehydrogenase inhibitor, which can prevent and control various plant diseases, especially the diseas...

AI Technical Summary

Problems solved by technology

[0007] When the above-mentioned tiflufenamide, fludioxonil, pyrimethrimol, and epoxiconazole are used alone, the spectrum of bactericidal action is narrow, the dosage is large, the residual effect period is short, and drug resistance is likely to occur
