Abstract
The invention discloses a bactericide composition of thifluzamide and fluazinam. The bactericide composition comprises common accessory ingredient, thifluzamide and fluazinam, wherein the mass fraction ratio of the thifluzamide to the fluazinam is (10 to 1) to (1 to 15), and the preferred ratio is (6 to 1) to (1to 9). After the thifluzamide and the fluazinam are compounded, the effect is improved remarkably, and the dosage of the effective components of compounded medicament is less than that of the effective components used separately, so that the bactericide composition is suitable for preventing and curing diseases caused by plant pathogens, such as phytophthora infestans, plasmodiophoromycetes and botrytis cinerea.
Description
Technical field
The bactericidal composition that the present invention relates to is take thifluzamide and fluazinam as active ingredient, is applicable to prevent and treat the disease that is caused by phytopathy originals such as phytophthora infestans, plasmodiophora brassicae, Botrytis cinerea, sclerotinite.
Background technology
Thifluzamide, english common name: thifluzamide, chemical formula C

2O
2S, chemical name 2,6-two bromo-2-methyl-4-trifluoromethoxy-4-Trifluoromethyl-1,3-thiazole-5-carbonyl acyl belongs to the thiazole amide bactericide for aniline, has strong interior conductivity and the long lasting effect of inhaling.Thifluzamide is the succinate dehydrogenase inhibitor.
Fluazinam, english common name: fluazinam, chemical name 3-chloro-N-(3-chloro-5-trifluoromethyl-2-pyridine radicals)-α, α, α-three fluoro-2,6-dinitro-p-toluidine.Fluazinam is protective fungicide, and present commercial formulation is suspending agent, and using method is mainly cauline leaf, the soil spraying is processed.
Phytophthora infestans mainly causes potato late blight, tomato blight; Plasmodiophora brassica bacteria mainly causes crucifer club root; Sclerotinite mainly causes all kinds of sclerotium diseases; Botrytis cinerea mainly causes all kinds of crop gray molds.
Have no at present the composite report of thifluzamide and fluazinam.
Summary of the invention
The purpose of this invention is to provide a kind of efficient, low toxicity, low-residual,, active ingredient good, lower-cost to Environmental compatibility is the bactericidal composition of thifluzamide and fluazinam.
The present invention is achieved through the following technical solutions: a kind of bactericidal composition, active ingredient is thifluzamide and fluazinam, thifluzamide and the fluazinam mass ratio in composition is 10:1～1:15, preferred proportion is 6:1～1:9, and thifluzamide and the fluazinam gross mass mark percentage composition in composition is 6%～60%.
The production technology that described microbicide compositions adding auxiliary agent and excipients are all known according to those skilled in the art is made suspending agent, water dispersible granules, wetting powder.
Bactericidal composition of the present invention is compared with single product, has the characteristics of binary bactericidal composition, has enlarged the effective active scope, to the potato late blight that is caused by phytophthora infestans; The crucifer club root that plasmodiophora brassica bacteria causes; The microbial all kinds of plant stalk breaks of nuclear disk; All kinds of crop gray molds that Botrytis cinerea causes have good preventive effect, and have delayed drug-fast generation, and the lasting period is long, has reduced dosage and access times, save cost, and are easy to use, the time and labour saving, and minimizing is to the pollution of environment.
