Description

A kind of bactericidal composition

Technical field

The invention belongs to agriculture chemicals fungicide field, be specifically related to a kind of bactericidal composition, be made up of difenodiconazole, propamidine, lentinan and adjuvant.

Background technology

Difenodiconazole (Difenodiconazole), chemical name: 2-[2-chloro-4(4-chlorobenzene oxygen) phenyl]-1, double (the 1H-1 of 3-, 2,4-triazol-1-yl)-2-propanol, belong to triazole bactericidal agent, it is possible to the plant disease that the multiple pathogenic fungi such as preventing and treating Botrytis, interlink spore genus, Verticillium cause.

Propamidine (Propamidine); it is a kind of aromatic diamidino compounds, absorption in having preferably, can be in plant body absorption, distribution and metabolism; there is protection and therapeutical effect simultaneously, to by the microbial plant botrytis of Botrytis cause of disease, there is good preventive effect especially.

Lentinan (lentinan), it it is the effective ingredient extracted from mushroom fruiting body, both having had stronger pathogen suppression and killing action, and had again obvious disease-resistant yield-increasing, the effect of raising crop quality, mixed with the antibacterial of antifungal have good preventive and therapeutic effect to fungal diseases of plants.

Turfgrass is the important component part of urban afforestation, Landscape, and often the crowd is dense in these places, therefore Turfgrass Diseases not only affects attractive in appearance, and it is healthy that irrational prevention and controls also can affect civic, is required for turfgrass and proposes efficient, the antibacterial of low toxicity.At present, for purposes such as expanding prevention spectrums, the technology that pesticide activity components different to the mechanism of action, controlling object compounds use is widely used, but, the physicochemical property of different activities composition, action character are different, inappropriate compound scheme not only will not play its original biological activity, may cause the adverse consequences such as poisoning, harm environment on the contrary.Therefore, how selecting suitable active component to carry out the most compounding is a still problem in exploration.

Summary of the invention

In order to solve the problems referred to above, inventor is through long-term experiment, propose a kind of environmentally safe, human health is safe from harm and the bactericidal composition for urban green belts of excellent effect, described bactericidal composition is made up of difenodiconazole, propamidine, lentinan and auxiliary agent, three kinds of active component are learnt from other's strong points to offset one's weaknesses, expand fungicidal spectrum, and synergistic function can be produced.

The invention provides a kind of bactericidal composition, active component is difenodiconazole, propamidine and lentinan, and its part by weight is 1-80:1-30:1-80；Preferably 1-40:1-15:1-40；More preferably 1-10:1-3:1-6.

Microbicide compositions of the present invention can be prepared as the dosage form that agriculture field is conventional, comprises the most acceptable auxiliary agent kind accordingly, is preferably prepared to aqueous emulsion, microemulsion, water dispersible granules or wettable powder.

Described auxiliary agent includes one or more in emulsifying agent, thickening agent, antifreezing agent, wetting agent, dispersant, binding agent, solvent, filler, these auxiliary agents can select acceptable auxiliary agent kind in field of pesticide preparation, and emulsifying agent includes one or more in calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, agriculture breast 600, agriculture breast 1601#, this dish-60#, nekal formaldehyde condensation products；Thickening agent includes one or more in xanthan gum, Polyethylene Glycol, bentonite；Antifreezing agent includes one or more in ethylene glycol, propylene glycol, glycerol, carbamide, sodium chloride；Wetting agent include alkylsulfonate, naphthalene sulfonate, pull open in powder, spaonin powder one or more；Dispersant includes one or more in polycarboxylate, sodium lignin sulfonate, alkylnaphthalene sulfonate；Binding agent includes one or more in starch, dextrin, osseocolla, gelatin；Solvent includes one or more in Ketohexamethylene, dimethylbenzene, solvent naphtha, deionized water；Filler can include one or more in carbamide, sucrose, kieselguhr, Kaolin, white carbon, attapulgite.

The application in the medicine of preparation preventing and treating turfgrass Common fungi disease of the described bactericidal composition, the especially application in the medicine of preparation preventing and treating annual bluegrass leaf spot and Bluegrass Rust Disease.

The bactericidal composition that the present invention provides can produce following beneficial effect:

1, three kinds of active component mechanism of the present invention are different, and mutual mixture can produce synergistic function, be used alone with single component compared with, it is possible to be substantially reduced dosage, reduce cost.

2, the present invention is by carrying out mixture by three kinds of active component, expands its prevention and treatment range, particularly turfgrass Common fungi disease is had good prevention effect, especially annual bluegrass leaf spot and Bluegrass Rust Disease are had good prevention effect.

3, active component is to mammal low toxicity, environmentally friendly, is suitable in the environment such as urban afforestation, Landscape using.
