Abstract
The invention relates to a sterilization composition, in particular to a sterilization composition containing dosis efficax synergism sterilant of mancozeb and strobilurin, wherein the weight ratio of the mancozeb and the strobilurin is selected preferably (0.1:10)-(10:0.1), more preferably (1:10)-(10:1) and most preferably (1:1)-(9:1).
Description
Technical field
The present invention relates to a kind of Synergistic bactericidal composition, particularly relate to a kind of Synergistic bactericidal composition that comprises mancozeb and methoxy acrylic bactericide.
Background technology
Mancozeb is a kind of broad-spectrum high efficacy bactericide, the earliest U.S. Rohm.Hass company exploitation in 1961.Can prevent and treat downy mildew such as various crop, vegetables, fruit diseases such as cucumber, peanut, potato, paddy rice, tomato, grape, pears, apple, eqpidemic disease, grey mold, anthrax, black magnitude disease.Be to use one of the widest protective fungicide in the agricultural production.Because use for many years, some disease has produced pesticide resistance to mancozeb.In addition, mancozeb self is a kind of unstable compounds, and high temperature, high humidity, oxidation are prone to cause decomposition.To heat, wet responsive, the wetting powder that generally is processed into is prone to take place spontaneous combustion and decomposition failure.Have a strong impact on product quality and safety.Therefore press for mancozeb complex preparation and new formulation in producing to delay its pesticide resistance, to improve drug effect and safety.
Methoxy acrylic bactericide is the broad-spectrum high efficacy new type bactericide of Syngenta Co.,Ltd's invention.Have protection, treat, root out, infiltration, systemic action; Be used for multiple diseases such as control sac fungi, basidiomycetes, oomycetes, imperfect fungus such as various crop, vegetables, fruit tree, lawn and ornamental plants such as cereal crop, paddy rice, potato, melon, strawberry, apple, pears, good active all arranged like tens of kinds of diseases such as various eqpidemic diseases, downy mildew, powdery mildew, scab, rice blast, leaf mold, anthrax, foxiness, rust, glume blight, net blotchs.This series bactericidal agent has unique mechanism of action, belongs to the mitochondrial respiratory inhibitor, and failure energy is synthetic.And do not have cross resistance between other bactericide, the bacterial strain that sterol inhibitor, phenylamide, dicarboxylic dihydrazides amine and benzimidazole is produced resistance is effective.This series bactericidal agent all has effect to nearly all disease.It is bactericide kind at present the most promising and using value.But this series bactericidal agent is because action site is single, and germ can not be ignored its pesticide resistance problem.
The applicant is through discovering in a large number, and the bactericide of mancozeb and two kinds of different effects mechanism of methoxy acrylic is carried out compositely can having protective effect that treatment and eradicant action are arranged again, delays pesticide resistance, and improves bactericidal activity, enlarges fungicidal spectrum.Through lab screening, field control effectiveness test.Filter out mancozeb and methoxy acrylic bactericide formula combination with synergistic effect.Methoxy acrylic bactericide mainly contains kresoxim-methyl, Fluoxastrobin, oxime bacterium ester, SSF 126 etc.Based on above-mentioned discovery, the applicant has accomplished the present invention.
Summary of the invention
The object of the present invention is to provide a kind of mixed ratio reasonable, control efficiency is good, the Synergistic bactericidal composition that drug cost is low.
Another object of the present invention is to provide by formulations such as the formulated missible oil of this bactericidal composition, microemulsion, wetting powder, water dispersible granules.
