Abstract
A water-dispersing particle of BAS 490F for treating the powdery mildew of plant is proportionally prepared from BAS 490F, disperser, wetting agent, disintegrant, adhesive, stabilizer, and carrier through proportional mixing, pulverizing, granulating, drying and sieving.
Description
Technical field
The present invention relates to a kind of efficient germicide that is used for control of plant disease, relate to water dispersion granules agent of Kresoxim and preparation method thereof particularly.
Background technology
Agricultural chemicals conventional dosage forms such as missible oil, pulvis and wetting powder etc. account for 80% in China's preparation total amount, along with the development of processing formulation, the shortcoming of conventional dosage forms is apparent more outstanding.Contain organic solvents such as a large amount of dimethylbenzene, toluene in the missible oil, not only environment has been caused than severe contamination, and the petrochemical industry resource has been caused waste.Wetting powder often occurs dust from flying because its granularity is very thin in production and use, not only endanger people's health, also can cause environmental pollution, and low amounts of dust is flown upward and is easy to make crops to produce poisoning.Pulvis subject matter is the dust drift, and volume is big, is difficult for metering, existing arid area and some particular places of only being used for.Water dispersible granules has effectively been avoided the weak point of these conventional dosage forms, draws and utilized its advantage, develops very rapidly, is considered to 21st century pesticide processing field and has one of formulation of development prospect most.
Kresoxim-methyl (kresoxim-methyl) chemical name is (E)-2-methoxyimino-[2-(o-methyl-benzene oxygen methyl) phenyl] methyl acetate; it is the outstanding kind in the methoxy acrylate series bactericidal agent; its mechanism of action uniqueness; the activity that broad-spectrum high efficacy is arranged; vegetables, apple, pears and cereal class cereal crops now have been widely used in; most of diseases that pathomycetes such as imperfect fungus, sac fungi and oomycetes are caused have protection, treat and root out activity, are particularly useful for control of plant disease such as powdery mildew and scab.
The main formulation of the kresoxim-methyl sterilizing agent product of using on the agricultural chemicals market has wetting powder and dry suspending agent at present.And efficient, low toxicity, environment amenable water dispersion granules agent of Kresoxim are effectively used as yet, also do not see the correlation technique report.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of with kresoxim-methyl be that the preparation of former medicine is efficient, low toxicity, environment amenable nuisanceless bactericide, promptly water dispersion granules agent of Kresoxim can be used for the fungal diseases of plants control.
Another object of the present invention is to provide the preparation method of above-mentioned water dispersion granules agent of Kresoxim.
Purpose of the present invention is achieved through the following technical solutions:
A kind of water dispersion granules agent of Kresoxim, the percentage by weight of each component is in the prescription: kresoxim-methyl 4-67%, dispersant 1-12, wetting agent 1-15%, disintegrant 8-26%, adhesive 2-20%, stabilizing agent 1-8%, carrier 20-75%.
Described dispersant is selected from one or more in alkylnaphthalene sulfonate formaldehyde condensation products, dioctyl sodium sulphosuccinate, acrylate homopolymer sodium salt, the ethoxylated dodecyl alcohol.
Described wetting agent is selected from sodium lignin sulfonate, lauryl sodium sulfate, draw back in the powder one or more.
Described disintegrant is selected from one or more in bentonite, ammonium sulfate, the aluminium chloride.
Described adhesive is selected from one or more in polyethylene glycol, polyvinyl alcohol, the polyvinylpyrrolidone.
Described stabilizing agent is selected from one or more in sodium hydrogen phosphate, succinic acid, the borax.
Described carrier is selected from one or more in white kaolin, diatomite, the white carbon.
The manufacturing process of described kresoxim-methyl sterilizing water dispersible granules is:
Formulation material is mixed, be ground into powder through micro jet, add then and carry out granulation, drying in the fluidized bed prilling dryer, screening is after sample analysis, qualified can the packing.
Compared with prior art, water dispersion granules agent of Kresoxim of the present invention has following advantage:
1. fungicide preparation of the present invention is difficult for producing poisoning to environment, people and animals and other beneficial organism safety.
2. fungicide preparation of the present invention does not have dust, the particle disintegration rate is fast and do not have bales stained.
3. fungicide preparation bin stability of the present invention is good, can deposit more than 2 years.
4. fungicide preparation preparing process of the present invention is simpler, easy to use, is suitable for large scale application.
