Abstract
The invention discloses a bactericidal composition of propamidine and fluazinam. The bactericidal composition comprises commonly used auxiliary agents, propamidine and fluazinam. Mass part ratio of propamidine and fluazinam in the composition is 5:1-1:45, and preferably 3:1-1:25. When propamidine and fluazinam are compounded, a substantial synergetic effect is provided. Effective component dose of the compounded agent is substantially reduced than that of separate use. The composition provided by the invention is suitable to be used against crop gray mold caused by botrytis pathogen and crop stalk break casued by sclerotinia pathogen.
Description
Technical field
The bactericidal composition that the present invention relates to is take propamidine and fluazinam as active ingredient, the sclerotium disease that is applicable to prevent and treat the crop gray mold that caused by the Botrytis pathogen, is caused by the Sclerotinia pathogen.
Background technology
Propamidine, english common name propamidine, 1,3-two (4-amidino groups phenoxy group) propane.Propamidine is broad-spectrum germicide, has protection and therapeutic action, and the crop gray mold that is caused by the Botrytis pathogen, the sclerotium disease that is caused by the Sclerotinia pathogen are had outstanding preventive effect.
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.
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 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 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 adding auxiliary agent and excipients are all known according to those skilled in the art is made suspending agent, water dispersible granules, wetting powder.
The sclerotium disease that bactericidal composition of the present invention is used for crop gray mold that control causes by the Botrytis pathogen, is caused by the Sclerotinia pathogen.
Advantage of the present invention: the bactericidal composition that contains propamidine and fluazinam of the present invention, compare with single product, have the characteristics of binary bactericidal composition, enlarged the 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, save cost, and are easy to use, the time and labour saving, and minimizing is to the pollution of environment.
