Abstract
The invention discloses a bactericidal composition containing fluorine azole activated ester. The bactericidal composition contains an active component A and an active component B, the active component A is selected from fluorine azole activated ester, the active component B is selected from anyone of carbendazim, thiophanate methyl, prochloraz or its salts, and triflumizole, and a weight ratio of the active component A to the active component B is 1:80-60:1. The composition has a high activity against of a plurality of diseases on a plurality of crops, has an obvious synergistic effect and an enlarged sterilization spectrum, and also has the characteristics of small consumption, rain wash resistance and obvious synergy.
Description
Technical field
The invention belongs to technical field of pesticide, the application of the bactericidal composition that relates to a kind of fluorine-containing azoles Acibenzolar in crop pest.
Technical background
Fluorine azoles Acibenzolar is a class novel plant inducing anti-disease activator, and this compounds itself does not have bactericidal activity, and can produce infecting the resistance of germ by inducing plant on live plant.
The salt of Prochloraz comprises prochloraz-manganese chloride complex, prochloraz nantokite, prochloraz zinc salt.
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 agricultural chemicals is all additive effect, really has the seldom composite of synergistic effect, especially synergistic effect very obviously, synergy ratio very high composite just still less.Through inventor's research, discovery is mutually composite by fluorine azoles Acibenzolar and carbendazim, thiophanate-methyl, Prochloraz or its salt, fluorine bacterium azoles, there is within the specific limits good synergistic effect, and relevant composite about fluorine azoles Acibenzolar and carbendazim, thiophanate-methyl, Prochloraz or its salt, fluorine bacterium azoles, there is not yet at present relevant report at home and abroad.
Summary of the invention
The object of the invention is to propose a kind of bactericidal composition with synergistic function, use cost is low, preventive effect is good fluorine-containing azoles Acibenzolar.
The present invention is achieved through the following technical solutions:
A kind of bactericidal composition of fluorine-containing azoles Acibenzolar, contain active components A and active component B, active components A and active component B weight ratio are 1: 80～60: 1, described active components A is selected from fluorine azoles Acibenzolar, and active component B is selected from a kind of in carbendazim, thiophanate-methyl, Prochloraz or its salt, fluorine bacterium azoles; The weight ratio that is preferably active components A and active component B is 1 ︰ 60～40 ︰ 1; More preferably the weight ratio of fluorine azoles Acibenzolar and carbendazim is 1: 30～5: 1, the weight ratio of fluorine azoles Acibenzolar and thiophanate-methyl is 1: 40～5: 1, the weight ratio of fluorine azoles Acibenzolar and Prochloraz or its salt is 1: 30～5: 1, and the weight ratio of fluorine azoles Acibenzolar and fluorine bacterium azoles is 1: 20～10: 1; The weight ratio that most preferably is fluorine azoles Acibenzolar and carbendazim is 1: 24～1: 1, the weight ratio of fluorine azoles Acibenzolar and thiophanate-methyl is 1: 29～1: 9, the weight ratio of fluorine azoles Acibenzolar and Prochloraz or its salt is 1: 19～1: 1, and the weight ratio of fluorine azoles Acibenzolar and fluorine bacterium azoles is 1: 14～4: 1.
The bactericidal composition of described fluorine-containing azoles Acibenzolar, composition is made wetting powder, water dispersible granules, suspending agent, aqueous emulsion, microemulsion, suspension emulsion, microcapsule suspending agent, microcapsule suspension-suspending agent.
The disease of the bactericidal composition of described fluorine-containing azoles Acibenzolar for preventing and treating crop; Described crop comprises 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 powdery mildew, head blight, rice blast, root rot, brown spot, scab, stem wilt, stalk break, ring spot, rotten mildew, downy mildew, anthracnose, banded sclerotial blight, leaf spot, spot defoliation, epidemic disease, smut, green mould, penicilliosis, blossom-end rot, anthrachose of grape, fusarium wilt, leaf blight.
The amount of application when content of active component depends on independent use in bactericidal composition of the present invention, also depends on mixed ratio and the synergistic effect degree of a kind of compound and another kind of compound, and the while is also relevant with target disease.Conventionally in composition, the weight percentage of active component is gross weight 1%～90%, is preferably 5%～80%.According to different preparation types, active component content scope is different.Conventionally, liquid preparation contains 1%～60% 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 2%～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 processing method known in those skilled in the art, after being about to active component and mixing with liquid flux or solid carrier, then add surfactant as one or more in dispersant, stabilizing agent, wetting agent, binding agent, disintegrant, defoamer etc.According to different dosage form, in preparation, can also contain antifreeze known in those skilled in the art etc.
