Description
Technical field
The bactericidal composition that the present invention relates to, be with pungent bacterium amine and fluazinam for active ingredient, be applicable to prevent and treat the crop pest caused by pathogen fungi, bacterium, virus.
Background technology
Pungent bacterium amine is a kind of environment-friendly type amino acids high molecular polymer bactericide, is a kind of environment-friendly type, high-efficiency broad spectrum, low toxicity bactericide.Sterilization mechanism solidifies germ protein, destroys germ cell membrane, suppresses germ to breathe, make the sex change of germ enzyme system, thus kill germ.There is the features such as efficient, low toxicity, noresidue, and have good permeability, have certain eradicant action to the germ that hides invaded in bark, can be used to prevent and treat the multiple plant disease caused by pathogen fungi, bacterium and virus.Pungent bacterium amine has number of chemical isomer, and what bactericidal activity was higher mainly contains 3 kinds of isomer, and its chemical name is respectively: (a) N-n-octyl N-[2 (pungent amino) ethyl] ethane-1,2 diamines; (b) N-[2 (pungent amino) ethyl] decane-1,2 diamines; (c) [N-(2 is amino) decyl] decane-1,2 diamines.
Fluazinam, english common name fluazinam, the chloro-N-(3-of chemical name: 3-chloro-5-trifluoromethyl-2-pyridine radicals)-α, α, α-three fluoro-2,6-dinitros-p-toluidine.
Fluazinam is protective fungicide, all has very high activity to multiple pathogen fungi, and current commercial formulation is suspending agent, and using method is mainly cauline leaf, soil spraying process.
The same with other bactericide, there is resistance risk in long-term single use fluazinam or pungent bacterium amine.
Have no pungent bacterium amine and the composite report preventing and treating crop pest of fluazinam at present.
Summary of the invention
The object of this invention is to provide a kind of efficient, low toxicity, low-residual, the bactericidal composition that good, lower-cost to Environmental compatibility, active ingredient is pungent bacterium amine and fluazinam.
The present invention is achieved through the following technical solutions: a kind of bactericidal composition, active ingredient is pungent bacterium amine and fluazinam, pungent bacterium amine and fluazinam mass ratio are in the composition 10:1 ~ 1:50, preferably than being 4:1 ~ 1:35, pungent bacterium amine and fluazinam gross mass mark percentage composition is in the composition 5% ~ 85%.Described microbicide compositions adds auxiliary agent and excipients, and the production technology all known according to those skilled in the art makes water dispersible granules, wetting powder.Be applicable to prevent and treat the crop pest caused by pathogen fungi, bacterium, virus.
Of the present invention containing pungent bacterium amine and the composite bactericidal composition of fluazinam, good preventive effect is had to the crop pest caused by pathogen fungi, bacterium, virus, and drug-fast generation can be delayed, lasting period is long, decrease dosage and access times, cost-saving, easy to use, time and labour saving, environmentally friendly.
