Background technology
Propamidine, english common name propamidine, 1,3-bis-(4-amidino groups phenoxy group) propane.Propamidine is broad-spectrum germicide, has protection and therapeutic action, and the crop gray mold being caused by Botrytis pathogen, the sclerotium disease that caused by Sclerotinia pathogen are had to outstanding preventive effect.
Fluazinam, english common name fluazinam, the chloro-5-trifluoromethyl-2-of the chloro-N-(3-of chemical name 3-pyridine radicals)-α, α, α-tri-are fluoro-2,6-dinitro-p-toluidine.Fluazinam is protective fungicide, and current commercial formulation is suspending agent, and using method is mainly cauline leaf, soil spraying is processed.
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 propamidine and fluazinam.
Summary of the invention
The object 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 propamidine and fluazinam.
The present invention is achieved through the following technical solutions: a kind of bactericidal composition, active ingredient is propamidine and fluazinam, propamidine and the fluazinam mass ratio in composition is 5:1~1:45, preferably, than being 3:1~1:25, propamidine and the fluazinam gross mass mark percentage composition in composition is 3%~90%.
The production technology that described bactericidal composition adds auxiliary agent and excipients all to know according to those skilled in the art is made suspending agent, water dispersible granules, wetting powder.
Bactericidal composition of the present invention is for preventing and treating the crop gray mold being caused by Botrytis pathogen, the sclerotium disease being caused by Sclerotinia pathogen.
Advantage of the present invention: the bactericidal composition that contains propamidine and fluazinam of the present invention, compared with single product, there is the feature of binary bactericidal composition, expand effective active scope, to by 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, cost-saving, easy to use, time and labour saving, and reduce the pollution to environment.
