Description
Technical field
The present invention relates to weed killer herbicide, particularly relate to a kind of cyhalofop-butyl effervescent tablet of preventing and treating rice weed and preparation method thereof.
Background technology
Paddy rice is one of the world three generalized grain crops, and the control paddy field weed promotes the paddy rice sustainable development, realizes that growth of agricultural efficiency, peasant increase production significant.The majority that is applicable to paddy field at present is the weed killer herbicide of preparations such as missible oil, wetting powder, suspending agent such as bensulfuron-methyl, the third careless amine, butachlor; Could spray or spread fertilizer over the fields after generally need converting the water dilution during use or being made into pesticide-clay mixture; Troublesome poeration, labour intensity are big, and because of dosage or dispenser is inaccurate causes crop to be injured easily or the healthy influence of operator, environment are polluted; Therefore, press for the novel form replacement of some more laborsavingization.
Effervescent table as agricultural chemical is a kind of aqueous dispersion tablets that uses in the direct input paddy field of agricultural chemicals dust or droplet drift that do not have, effervesce disintegration rapidly when tablet is met water, even diffusion, contact target crop, thus reach control efficiency.Effervescent tablet is easy to use, can or be thrown into Tanaka with the tablet input, also can tablet be put into the sprayer that is filled with water, and saves labor no dust from flying; Environmental pollution is little, safe in utilization simultaneously, stores transportation safety, packaged convenience; Thereby will become the main direction of the development of the formulations of pesticide from now on.
Cyhalofop-butyl belongs to aryloxy group phenoxy propionic acid class weed killer herbicide, is a kind of paddy field selective herbicide, prevents and kill off grassy weeds such as barnyard grass grass, moleplant seed mainly as the cauline leaf inorganic agent.Cyhalofop-butyl is unique in the fragrant phenoxy propionic acid class weed killer herbicide paddy rice to be had the kind of tight security, and is the same with such other kinds, also is interior suction conductivity weed killer herbicide.Now main formulation is 10%, 15% or 100g/L missible oil, 10% aqueous cyhalofop-butyl emulsion, 10% cyhalofop-butyl microemulsion.Using needs the cost great amount of manpower and material resources, presses for the novel formulation of more laborsavingization.Effervescent tablet can satisfy the urgent demand of pesticide producing and processing enterprise well, has the prospect of promoting the use of preferably.In recent years, come into the market, in China Primary Study has been arranged also, but still do not had relevant report about the research of cyhalofop-butyl effervescent tablet up to now at effervescent tablet weed killer herbicides Japanese and the more existing kinds of American-European countries.
Summary of the invention
The object of the present invention is to provide a kind of cyhalofop-butyl effervescent tablet and preparation method thereof, a kind of use advantage that had both had existing weed killer herbicide has the effervescent tablet of the disposable input more more convenient than the method for using of existing general herbicide for paddy field again.
