Abstract
The present invention relates to the water dispersible granules of a kind of bactericidal composition.In bactericidal composition of the present invention, effective active composition Fenamidone, the mutual mixture of Ningnanmycin will not produce conflict；Compare single component and have synergistic effect, fungicidal spectrum can be expanded, be greatly improved the preventive effect to disease；Drug effect is more longlasting, and quick-acting is compared single dose and is also greatly improved；The water dispersible granules of herbicide of the present invention is easy to use, good stability, to crop safety.The present composition disease to the preventing and treating agricultural crops such as vegetables, cereal crop, fruit tree, especially to preventing and treating downy mildew, epidemic disease, powdery mildew have special efficacy.
Description
Technical field
The present invention relates to bactericidal composition technical field, be specifically related to the water dispersible granules of a kind 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), solubility (20 DEG C): 7.8mg/l in water.Mitochondrial respiratory inhibitor.Have tag, permeate, systemic activity, there is good protection and therapeutic activity.Preventing and treating, by the microbial downy mildew of Oomycete cause of disease, epidemic disease (including early blight and late blight) etc., also has good activity to fruit tree black spot.
Ningnanmycin belongs to low toxicity Antibiotics bactericide, the innovation biological pesticide 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 preventing and treating sclerotinia rot of colza, peronophythora litchi, large scale application the most in the multiple diseases such as other crop virosis, stem rot, blight dis-ease, powdery mildew.
Both the above medicine is after long-term being used alone, plant germ is the most easily made to develop immunity to drugs, causing the problems such as dosage increasing, preventive effect reduction, lasting period shortening, the Reusability of agricultural chemicals causes agricultural chemicals degradation rate in soil to decline, and is unfavorable for very much environment sustainable development.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides the water dispersible granules of a kind of bactericidal composition.In bactericidal composition of the present invention, effective active composition Fenamidone, the mutual mixture of Ningnanmycin will not produce conflict；Compare single component and have synergistic effect, fungicidal spectrum can be expanded, be greatly improved the preventive effect to disease；Drug effect is more longlasting, and quick-acting is compared single dose and is also greatly improved；Having delayed drug-fast generation, low-residual, degradable in soil after the lasting period, consumption is few, to more environment-friendly, meets the requirement of agricultural production；To crop safety.The present composition disease to the preventing and treating agricultural crops such as vegetables, cereal crop, fruit tree, especially to preventing and treating downy mildew, epidemic disease, powdery mildew have special efficacy.
The water dispersible granules of a kind of bactericidal composition of the present invention is to be realized by following technical scheme: the active ingredient of described bactericidal composition includes: Fenamidone, Ningnanmycin, wherein, active ingredient accounts for 45-80 part of herbicide gross mass, also include dispersant 3-20 part, wetting agent 3-10 part, disintegrant 2-5 part, filler 1-70 part.
Described Fenamidone, the part by weight of Ningnanmycin are 1-20:1-20.
Fenamidone, the part by weight of Ningnanmycin are 5-10:1:5.
Preferably, Fenamidone, the part by weight of Ningnanmycin are 7:3.
By formula, Fenamidone, Ningnanmycin and dispersant, wetting agent, disintegrant and filler are mixed, pulverize with micro jet, through mediating, it is subsequently adding in fluidized-bed granulation dryer and carries out granulation, dry, screening, prepare herbicide water dispersible granule.
Described dispersant is: fatty acid glyceride APEO.
Described wetting agent is: lauryl sodium sulfate.
Described disintegrant is: citric acid.
Described filler is: bentonite.
The water dispersible granules of this bactericidal composition is for preventing and treating the downy mildew of crop, epidemic disease, the powdery mildew diseases such as agricultural vegetables, cereal crop, fruit tree.
Beneficial effects of the present invention:
Present composition effective active composition Fenamidone, both Ningnanmycins mutually mixture will not produce conflict；The present composition compares single component synergistic effect, can expand fungicidal spectrum, is greatly improved the preventive effect to disease；Drug effect is more longlasting, and quick-acting is compared single dose and is also greatly improved；Low-residual, degradable in soil after the lasting period, consumption is few, to more environment-friendly, meets the requirement of agricultural production；The present composition disease to the preventing and treating agricultural crops such as vegetables, cereal crop, fruit tree, especially to preventing and treating downy mildew, epidemic disease, powdery mildew have special efficacy.The water dispersible granules of herbicide of the present invention is easy to use, good stability, to crop safety.
