Abstract
The invention discloses a compound bactericidal composition containing penflufen. The bactericidal composition comprises the following effective constituents: an active component A and an active component B, wherein the active component A is penflufen, the active component B is any one compound selected from the group consisting of kasugamycin, validamycin, polyoxin and pyrimidine nucleoside antibiotic, and a weight ratio of the active component A to the active component B is 1:80 to 80: 1. The bactericidal composition provided by the invention exerts a synergistic effect on a plurality of diseases doing harm to agricultural production, reduces the dosage of pesticides, decreases residual quantity of pesticides on crops, mitigates environmental pollution, is safe to human beings and livestock, has good environmental compatibility and enables drug resistance not to easily generate.
Description
Technical field
The invention belongs to technical field of pesticide, the application of the combination sterilization composition that relates to a kind of fluorine-containing azoles bacterium aniline on corps diseases.
Background technology
Fluorine azoles bacterium aniline (penflufen): molecular formula is C
18h
24fN
3o, chemical name is 2 ＇-[(RS)-1,3-dimethylbutyl]-5-fluoro-1,3-dimethyl pyrazole-4-formailide, fluorine azoles bacterium aniline is a kind of succinate dehydrogenase inhibitors, and Main Function transmits Complex II in respiratory chain electronics, blocking-up energy metabolism.Can prevent and treat kind pass, basidiomycetes and sac fungi disease that soil passes, mainly contain potato black scurf that rhizoctonia causes, wheat sharp eyespot, rice sheath blight disease, sclerotinia rot of colza etc., also have loose smut of wheat, the bunt of wheat, corn southern leaf blight etc.Seed after treatment can absorb fluorine azoles bacterium aniline in germination process, is transmitted to other positions of plant corpus by xylem, plays the effect of cover crop.
Kasugarnycin, jinggangmeisu, polyoxin, antibiotic in pyrimidine nucleoside class all belong to common fungicide, be widely used in the disease of crops, because antibiotic in pyrimidine nucleoside class is referred to as pesticide corrosion 120, below all with pesticide corrosion 120 substitute antibiotic in pyrimidine nucleoside class.
But in the real process of agricultural production, preventing and treating the problem that disease the most easily produces is the generation of disease drug resistance.Different cultivars composition carries out composite, is to prevent and treat the very common method of resistance disease.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of sterilization is all additive effect, really have a synergistic effect composite seldom, especially synergistic effect very obviously, synergy ratio very high composite just still less.Through inventor's research, find after fluorine azoles bacterium aniline and kasugarnycin, jinggangmeisu, polyoxin, pesticide corrosion 120 is composite to produce good synergistic effect, and not yet open about the composite relevant report of fluorine azoles bacterium aniline and kasugarnycin, jinggangmeisu, polyoxin, pesticide corrosion 120.
Summary of the invention
The object of the invention is to propose a kind of combination sterilization composition with synergistic function, use cost is low, preventive effect is good fluorine-containing azoles bacterium aniline.
The combination sterilization composition active ingredient of the fluorine-containing azoles bacterium aniline that the present invention proposes is active components A and active component B, activity is divided into A and active component B weight ratio is 1 ︰ 80～80 ︰ 1, described active components A is selected from fluorine azoles bacterium aniline, active component B is selected from the one in kasugarnycin, jinggangmeisu, polyoxin, pesticide corrosion 120, and active components A and the preferred weight ratio of active component B are 1 ︰ 50～50 ︰ 1; More preferably the weight ratio of fluorine azoles bacterium aniline and kasugarnycin is 1 ︰ 20～25 ︰ 1, and the weight ratio of fluorine azoles bacterium aniline and jinggangmeisu or polyoxin or pesticide corrosion 120 is 1 ︰ 25～25 ︰ 1; The weight ratio that most preferably is fluorine azoles bacterium aniline and kasugarnycin is 1 ︰ 4～11 ︰ 1, and the weight ratio of fluorine azoles bacterium aniline and jinggangmeisu or polyoxin is 1 ︰ 9～4 ︰ 1, and the weight ratio of fluorine azoles bacterium aniline and pesticide corrosion 120 is 1 ︰ 4～4 ︰ 1.
The combination sterilization composition of the fluorine-containing azoles bacterium aniline that the present invention proposes is for preventing and treating the purposes of disease on crops, and described crops comprise cereal crops, legume crop, fiber crop, sugar [yielding, melon crop, fruits crop, dry fruit crop, hobby crop, root crop, oil crop, flowers crop, medicinal crop, raw material crop, green manure pasture crop; Described disease comprises banded sclerotial blight, stalk break, smut, powdery mildew, rust, downy mildew, epidemic disease, gray mold, brown spot, damping off, fusarium wilt, ring spot, rice blast, anthracnose, angular leaf spot, false smut or bakanae disease.
The weight ratio of active components A, active component B is 1 ︰ 80～80 ︰ 1.Conventionally in composition, the weight percentage of active component is gross weight 0.5%～90%, is preferably 5%～80%.According to different preparation types, active component content scope is different.Conventionally, liquid preparation contains 1%～70% active substance by weight, is preferably 5%～50%; Solid pharmaceutical preparation contains 5%～80% active substance by weight, is preferably 10%～80%.
In bactericidal composition of the present invention, at least contain a kind of surfactant, the dispersion of active component in water while being beneficial to use.Surface-active contents is 5%～30% of total formulation weight amount, and surplus is solid or liquid diluent.
Bactericidal composition of the present invention can be by user before use through dilution or directly use.Its preparation can be prepared by common processing method known in those skilled in the art, after mixing with liquid flux or solid carrier by active substance, then add surfactant as one or more in dispersant, wetting agent, binding agent, defoamer, disintegrant, antifreeze etc.
Bactericidal composition of the present invention, can be processed on demand acceptable formulation in any sterilization, wherein more preferably formulation is wetting powder, water dispersible granules, suspending agent, aqueous emulsion, microemulsion or microcapsule suspending agent, can also make aqua, soluble powder, soluble granula, suspension emulsion or microcapsule suspension-suspending agent.
