Abstract
The present invention discloses one kind of germicide composition containing prochloraz or its manganese salt and propiconazol and its application. The composition contains prochloraz or its manganese salt and propiconazol in the weight ratio of 5-45 to 1-40. The composition may be used in preventing and controlling diseases of grain crop, melons, fruits and vegetable, and has wide application range, low cost and high plant disease preventing and controlling effect.
Description
Technical field
The present invention relates to a kind of bactericidal composition and uses thereof, especially a kind of is the bactericidal composition and the application thereof of main active with Prochloraz or its manganese salt and propiconazole.
Background technology
Prochloraz (prochloraz) (or its manganese salt prochloraz-manganese chloride complex) is a kind of efficient, broad spectrum activity imidazoles bactericide and freshness preserving agent for fruit and vegetable, be used for cereal controls pseudo-cercospora, nuclear cavity Pseudomonas, spore and belong to and the Septoria fungi, to early stage eye spot disease, leaf spot and powdery mildew, preventive effect is arranged.Be used for that oilseeds, grape can be prevented and treated Alternaria, Botrytis, pseudo-cercospora, bury Sclerotinia, the Sclerotinia fungi.Living Cercospora and Erysiphe on Ascochyta on the control leguminous plant, Botrytis, the beet have preventive and therapeutic effect for the cochliobolus genus on the cereal, Fusarium, nuclear cavity Pseudomonas, the fungus-caused disease of Septoria.In addition, can prevent and treat the cauliflower leaf spot, rice blast.
Prochloraz is in Crop in China, and especially fresh-keeping aspect is widely used, and use obtains good result on rice blast does not also have the pertinent literature explanation.
Propiconazole (propiconazol) is the systemic fungicide with protection and therapeutic action.Can be absorbed by root, stem, leaf portion, and can be soon in the plant strain body on conduction, the control sac fungi, the disease that basidiomycetes and imperfect fungus cause belongs to the biosynthetic inhibitor of ergosterol.Ergosterol plays an important role in the formation of fungal cell membrane, and propiconazole is by disturbing C
14-demethylation and hinder the biosynthesis of ergosterol in the fungus body, thus the fungi growth breeding destroyed, play protection and therapeutic action.Propiconazole is except that invalid to the phycomycete disease, and the multiple diseases that Saccharomyces, basidiomycetes number, Dendrochium fungi are caused on cereal crops, vegetables, fruit and ornamental plants is effective.
Propiconazole has certain therapeutic action for the pathogen of rice blast, but single use propiconazole can not reach the effect of control rice blast.
Summary of the invention
The objective of the invention is to strive to above-mentioned technical problem provide a kind of applied widely, cost is low, the effective plant sterilization composition that contains Prochloraz or its manganese salt and propiconazole.
A further object of the invention provides the purposes of this bactericidal composition.
The objective of the invention is to realize by following measures:
A kind of bactericidal composition, it contains Prochloraz (or its manganese salt) and propiconazole, and wherein Prochloraz (or its manganese salt) is 5～45: 1～40 with the weight ratio of propiconazole.
Described bactericidal composition, wherein Prochloraz (or its manganese salt) is 10～45: 2～30 with the propiconazole weight ratio.
Described bactericidal composition, wherein Prochloraz (or its manganese salt) and propiconazole and known auxiliary agent and excipient are re-dubbed any one preparation that allows on the agricultural chemicals.These known auxiliary agents, excipient have dispersant, diffusant, defoamer, wetting agent, disintegrant etc.
Described bactericidal composition, its formulation are pulvis, wetting powder, suspension emulsion or missible oil.
The application of described bactericidal composition aspect control cereal class, melon and fruit or vegetable crop disease is particularly useful for preventing and treating rice blast.
Beneficial effect of the present invention:
1, used Prochloraz (or its manganese salt) and the propiconazole of the present invention all is azoles fungicide, therefore has identical mechanism of action, be mixed mutually to produce low touching, but Synergistic reduces dosage, reduces cost.
2, the present composition scope of application increases, be applicable to the crop pest of control cereal class, various melon and fruit, vegetables, particularly prevent and treat crop pests such as paddy rice, wheat, capsicum, banana, mango, pineapple, cucumber, tomato, being particularly useful for preventing and treating rice blast has effect preferably.
