Abstract
The invention relates to wettable powder of a bactericidal composition. The wettable powder has the beneficial effects that the active ingredients including fenamidone and ningnanmycin in the bactericidal composition do not collide with each other when being mixed with each other; compared with the single ingredient, the composition has synergistic effects and can achieve the effects of expanding the bacterial spectrum and greatly improving the control effects on diseases; the efficacy lasts longer, and the fast-acting property is greatly improved compared with that of the single agent; the wettable powder conduces to delaying the drug resistance, is low in residues, is easy to degrade in soil after the lasting period, is low in consumption, is more environment-friendly and meets the requirements of agricultural production; the wettable powder is safe to crops; the composition has special control effects on the diseases of the crops, such as agricultural vegetables, cereal crops and fruit trees, especially on downy mildew, epidemic diseases and powdery mildew.
Description
Technical field
The present invention relates to bactericidal composition technical field, be specifically related to a kind of wetting powder of bactericidal composition.
Background technology
Fenamidone chemical name: (S)-5-methyl-2-methyl mercapto-5-phenyl-3-anilino--3,5-glyoxalidine-4-ketone, structural formula is
, belong to imidazolone type, white powdery solid, fusing point is 137 DEG C, and density is 1.285, vapour pressure 3.4 × 10-7Pa(25 DEG C), solvability (20 DEG C): 7.8mg/l in water.Mitochondrial respiratory inhibitor.Have tag, permeate, systemic activity, there is good protection and therapeutic activity.Control, by the microbial downy mildew of Oomycete cause of disease, epidemic disease (comprising early blight and late blight) etc., also has good activity to fruit tree black spot.
Ningnanmycin belongs to low toxicity Antibiotics bactericide, the innovation biopesticide succeeded in developing by Chengdu Inst. of Biology, Chinese Academy of Sciences, tobacco mosaic virus disease, tomato virus disease, pepper virus disease, rice seedling blight, root rot, stripe disease, alternaria leaf spot of apple, powdery mildew of cucumber achieve registration, this external control sclerotinia rot of colza, peronophythora litchi, also large scale application in the multiple diseases such as other crop virosis, stem rot, blight dis-ease, powdery mildew.
Above two kinds of medicines are after long-term being used alone, plant germ is all easily made to develop immunity to drugs, cause the problems such as dosage increasing, preventive effect reduction, lasting period shortening, the Reusability of agricultural chemicals causes the degradation rate of agricultural chemicals in soil to decline, and is unfavorable for environment sustainable development very much.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of wetting powder of bactericidal composition.In bactericidal composition of the present invention, effective active composition Fenamidone, the mutual mixture of Ningnanmycin can not produce conflict; Compare single component and have synergistic effect, can fungicidal spectrum be expanded, greatly improve the preventive effect to disease; Drug effect is more lasting, and quick-acting compares single dose also very big raising; Delayed drug-fast generation, low-residual, easily degraded after the lasting period in soil, and consumption is few, more friendly to environment, met the requirement of agricultural production; To crop safety.The present composition to the disease of crops such as control agriculture vegetables, cereal crop, fruit tree etc., especially to preventing and treating downy mildew, epidemic disease, powdery mildew have special efficacy.
The wetting powder of a kind of bactericidal composition of the present invention is realized by following technical scheme: the active ingredient of described bactericidal composition comprises: Fenamidone, Ningnanmycin, wherein, active ingredient accounts for 75-100 part of weed killer herbicide gross mass, also comprise dispersant 3-20 part, wetting agent 3-10 part, filler 1-70 part.
Described Fenamidone, the part by weight of Ningnanmycin are 1-20:1-20.
The part by weight of Fenamidone, Ningnanmycin is 5-10:1:5.
Preferably, the part by weight of Fenamidone, Ningnanmycin is 7:3.
By formula by Fenamidone, Ningnanmycin and dispersant, wetting agent and filler mixing, uniform stirring in stirred tank, is mixing, is making wetting powder after airslide disintegrating mill.
Described dispersant is: alkyl benzene sulfonate calcium salt.
Described wetting agent is: lauryl sodium sulfate.
Described filler is: kaolin.
The wetting powder of this bactericidal composition is for preventing and treating downy mildew, epidemic disease, the powdery mildew disease of the crops such as agriculture vegetables, cereal crop, fruit tree.
Beneficial effect of the present invention:
Present composition effective active composition Fenamidone, both Ningnanmycins mutually mixture can not produce conflict; The present composition compares single component synergistic effect, can expand fungicidal spectrum, greatly improves the preventive effect to disease; Drug effect is more lasting, and quick-acting compares single dose also very big raising; Low-residual, easily degraded after the lasting period in soil, and consumption is few, more friendly to environment, met the requirement of agricultural production; The present composition to the disease of crops such as control agriculture vegetables, cereal crop, fruit tree etc., especially to preventing and treating downy mildew, epidemic disease, powdery mildew have special efficacy.The wetting powder of bactericidal composition of the present invention is easy to use, and accumulating is convenient, to crop safety.
