Abstract
The invention discloses a kind of synergic bactericide composition and preparation method thereof, it is characterized in that containing the pungent bacterium amine of active ingredient, chlorobromide isocyanuric acid and additive, with the gross weight of composition for benchmark, pungent bacterium amine content is 1 ~ 30%, chlorobromide isocyanuric acid content is 1 ~ 30%, auxiliary agent content is 2 ~ 25%, and filer content is 15 ~ 96%.Above-mentioned raw materials is added after mixing in enamel stirred tank, after air-flow crushing or grinding, make wetting powder or the SC-like microbicide compositions containing pungent bacterium amine and chlorobromide isocyanuric acid.Pungent bacterium amine and the composite use of chlorobromide isocyanuric acid, low toxicity, low-residual, insecticidal spectrum are wide, and lasting effect is good, and cost is low, especially has the feature of non-environmental pollution control, are to prevent and treat the ideal pesticide species of the diseases such as bacterial leaf streak of rice.
Description
Technical field
The present invention relates to a kind of synergic bactericide composition, show and all have stronger preventing disease theraping effect to agricultural disease, can be applicable to multiple diseases such as control bacterial leaf streak of rice, banded sclerotial blight etc.This microbicide compositions is different from other microbicide compositions existing or agricultural chemicals single dose, adopt the reasonable combination of the pungent bacterium amine of low toxicity highly effective pesticide and these two kinds of agricultural chemicals of chlorobromide isocyanuric acid, the generation of disease drug resistance can be delayed, use simple, safety, control efficiency is good, and residual quantity is low environmentally safe, promote Crop securify and fine quality production, agricultural production and income is played an important role.
Background technology
Bacterial leaf streak of rice, banded sclerotial blight are the important diseases of paddy rice, and the several hundred million mu of annual onset area is the serious hindrance of China's rice high yield stable yields.And realize developing direction and the objective of the struggle that the control of rice disease harmless boilogical is agricultural plant protection field.In recent years, although country prohibites use high-toxic pesticide on paddy rice, but for want of efficient disease control medicament and use the phenomenon of high poison, persistent pesticide also comparatively general in actual agricultural production process, therefore, research and develop high-efficiency low-toxicity, the novel agrochemical of low-residual is inevitable development trend.
Pungent bacterium amine is obtained the modes such as cell membrane, coagulated protein, prevention breathing and ferment activity and reaches sterilization (virus) by all kinds of pathogene of destruction.This medicine has certain interior suction and osmosis, kills significantly and inhibitory action causing the various plants fungi of crop pest, bacterium and virus all to have.
Because alone pungent bacterium amine is longer in the time limit that Main Rice Diseases is prevented and treated, the pesticide resistance of crop pest has had significant enhancing.
Chlorobromide isocyanuric acid (chloroisobrominecyanuricacid) have the bacterium of crop, fungi, virus strong to kill, interior suction and protection dual-use function; this medicine sprays and can discharge Cl and Br at leisure in crop surface; form hypochlorous acid (HOCl) and bromic acid (HOBr), therefore there is strong bactericidal action.But the chlorobromide isocyanuric acid single dose of alone high-load is relatively high in current use cost.
Summary of the invention
The object of the invention is for efficient at present, the multiple deficiency that broad spectrum disease agricultural chemicals very lacks and existing agricultural chemicals single dose exists, a kind of synergic bactericide composition being product forms with wetting powder or suspending agent is provided, the reasonable combination mixture of the pungent bacterium amine of low toxicity highly effective pesticide and these two kinds of agricultural chemicals of chlorobromide isocyanuric acid is adopted to use, it had both retained the broad-spectrum of the pungent bacterium amine of low toxicity highly effective pesticide and chlorobromide isocyanuric acid and the advantage good to the control efficiency of disease, the shortcoming of existence can be overcome again, realize the target of corps diseases non-environmental pollution control, reduce the toxicity to other biology, reduce chemical substance remaining crops, expand fungicidal spectrum, reduce costs, to adapt to the requirement that China uses low toxicity highly effective pesticide production estimation such as paddy rice.
A kind of synergic bactericide composition takes following scheme to realize: a kind of biological-chemical synergic bactericide composition, it is characterized in that microbicide compositions is made up of the pungent bacterium amine of active ingredient and chlorobromide isocyanuric acid, composition raw materials percentage by weight is pungent bacterium amine content is 1 ~ 30%, chlorobromide isocyanuric acid content is 1 ~ 30%, auxiliary agent content is 2 ~ 25%, and filer content is 15 ~ 96%.A kind of biological-chemical synergic bactericide composition makes suspending agent or wetting powder.
When this product forms is wetting powder, described auxiliary agent auxiliary agent is by dispersant 1 ~ 20%, and wetting agent 1 ~ 5% forms, and dispersant adopts lignosulfonates, NNO, the one pulling open powder or any two or three mixture.Wherein, lignosulfonates select calcium lignosulfonate or sodium lignin sulfonate; Wetting agent adopts sodium alkyl benzene sulfonate or alkyl benzene calcium sulfonate.Filler adopts a kind of in silica-based, precipitated calcium carbonate, white carbon or mixture, silica-based employing potter's clay, kaolin and diatomite etc.
When this product forms is suspending agent, described auxiliary agent is by dispersion moisture agent 1 ~ 15%, antifreeze 0.3 ~ 3%, thickener 0.4 ~ 5%, defoamer 0.3 ~ 2% forms, dispersion moisture agent adopts polyoxyethylene tri-styryl phosphenylic acid salt, or alkylnaphthalene sulfonate, or one in alkylphenol polyoxyethylene or mixture; Antifreeze adopts antifreeze to adopt alcohols, selects propane diols or glycerine or ethylene glycol; Thickener adopts xanthans or aluminium-magnesium silicate; Defoamer adopts silicone defoaming agent.Filler adopts water.
A kind of its preparation process of synergic bactericide composition: weigh pungent bacterium amine and chlorobromide isocyanuric acid, auxiliary agent and filler by said ratio, after it is characterized in that first pungent bacterium amine, chlorobromide isocyanuric acid and auxiliary agent, filler fully being mixed in enamel stirred tank, after airslide disintegrating mill is pulverized or sand mill grinds, mix obtained finished product again, finished product meets or higher than the every compulsory index requirement of country to wetting powder or suspending agent product.
The pungent bacterium amine of the present invention and chlorobromide isocyanuric acid Recompounded pesticide, low toxicity, low-residual, fungicidal spectrum are wide, and synergy is obvious, and control efficiency is good, and cost accounting reduces, and are the ideal higher effective and lower toxic pesticide preparation varieties of control bacterial leaf streak of rice evil.
The formulation that this microbicide compositions is made have produce simple, efficient, preparation cost is low, many advantages such as environment compatibility is good.This microbicide compositions is different from other microbicide compositions existing, can delay drug-fast generation, reaches the object of agricultural production and income and food safety production.
