Abstract
The invention discloses a cyhalofop-butyl water-dispersible granule and a preparation method thereof. The cyhalofop-butyl water-dispersible granule is prepared by the following steps of: adding a wetting agent, a dispersant, a disintegrant, an adhesive and a carrier into an effective component cyhalofop-butyl, uniformly mixing, then regulating a pH value to 4-10 by using a pH regulator, then crushing with airflow to prepare a wettable powder, and granulating, drying and sieving the wettable powder to obtain the cyhalofop-butyl water-dispersible granule. The environment-friendly preparation form of the cyhalofop-butyl, which is provided by the invention, has the advantages of the wettable powder and a suspending agent and overcomes the deficiencies of the two preparation forms.
Description
Technical field
The present invention relates to a kind of cyhalofop-butyl water dispersible granules and preparation method thereof.
Background technology
Cyhalofop-butyl is the phenoxy carboxylic acid herbicides of LG-DOW agricultural science company exploitation, and it is cauline leaf processing selecting weed killer herbicide behind the best paddy field seedling of generally acknowledging in the world at present, and is good to transplanting and direct seading rice safety, is a kind of interior conductivity weed killer herbicide of inhaling.Cyhalofop-butyl is absorbed by the blade and the leaf sheath of plant corpus, and the phloem conduction accumulates the meristem zone in plant corpus, resist acetyl-CoA carboxylase, fatty acid is synthesized stop, the growth division of cell can not normally be carried out, film system etc. contains the fat structural deterioration, causes plant death at last.It is slower to be absorbed into weeds death from cyhalofop-butyl, generally needs 1-3 week.Cyhalofop-butyl is good to grassy weed effects such as barnyard grass grass, Paspalum distichums, and moleplant seed is had special effect.
Water dispersible granules is the novel form that grows up on the basis of wetting powder and suspending agent, it has good dispersion, suspensibility height, good stability, characteristics such as easy to use, avoided wetting powder and easily produced dust, the suspending agent storage easily produces shortcomings such as precipitation, caking, mobile poor, sticking wall.Water dispersible granules is used conveniently, and non-environmental-pollution also has the advantage of traditional formulations of pesticide, and safety is good.The preparation of relevant cyhalofop-butyl list agent has missible oil, aqueous emulsion, microemulsion, aqueous suspension agent etc. in the market, and the water dispersible granules of relevant cyhalofop-butyl yet there are no report.
Summary of the invention
One of technical problem to be solved by this invention be at wetting powder and suspending agent separately deficiency and a kind of cyhalofop-butyl water dispersible granules is provided, this cyhalofop-butyl water dispersible granules had both had the advantage of wetting powder and suspending agent, had overcome the deficiency of these two kinds of formulations again.
Two of technical problem to be solved by this invention is to provide the preparation method of above-mentioned cyhalofop-butyl water dispersible granules.
As the cyhalofop-butyl water dispersible granules of first aspect present invention, its active ingredient is cyhalofop-butyl, and formulation is a water dispersible granules.
Cyhalofop-butyl water dispersible granules of the present invention is made up of cyhalofop-butyl, wetting agent, dispersant, disintegrant, adhesive and carrier, and the pH value is 4-10; The percentage by weight of each component is as follows in per 100 parts of cyhalofop-butyl water dispersible granules:
Cyhalofop-butyl 5%～95%;
Wetting agent 1%～4%;
Dispersant 2%～6%;
Disintegrant 3%～10%;
Adhesive 0.5%～2%;
Carrier is supplied.
Wetting agent of the present invention is preferably one or more mixing in lauryl sodium sulfate, neopelex, fatty alcohol polyglycol ether sulphate, aliphatic alcohol polyethenoxy base ether, Teepol, alkyl naphthalene sulfonic acid formaldehyde condensation products and the alkylnaphthalene sulfonate.
Described dispersant is preferably the sodium salt of sodium lignin sulfonate, calcium lignosulfonate, Sodium Polyacrylate, polyvinylpyrrolidone, alkyl amide taurate, sodium methylene bis-naphthalene sulfonate, dispersing agent MF, alkyl naphthalene sulfonic acid condensation polymer and one or more mixing in the sodium methylene bis-naphthalene sulfonate formaldehyde condensation products.
Described disintegrant is a kind of in urea, ammonium sulfate, calcium chloride, sodium chloride, magnesium chloride and the aluminium chloride.
Described adhesive is a kind of in soluble starch, dextrin, gum Arabic and the polyvinyl acetate.
Carrier is a kind of in diatomite, white carbon, bentonite, kaolin, precipitated calcium carbonate and the attapulgite.
The preparation method of the cyhalofop-butyl water dispersible granules of second aspect present invention, it is characterized in that, press proportion relation with cyhalofop-butyl, wetting agent, dispersant, disintegrant, adhesive and carrier mixing after, regulate the pH value to 4-10 with the pH regulator agent, comminution by gas stream, make wetting powder, carry out granulation, dry, screening obtains product.
Described pH regulator agent is acid or alkali.
Cyhalofop-butyl water dispersible granules of the present invention had both had the advantage of wetting powder and suspending agent, had overcome the deficiency of these two kinds of formulations again.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer and more definite, below in conjunction with example the present invention is done to describe in further detail, describe only limiting to better explain the present invention herein, and be not used in qualification the present invention.Embodiment provides the prescription of part cyhalofop-butyl water dispersible granules for the technical staff, and the technical staff can prepare with reference to these prescriptions.
Embodiment 1
By weight percentage cyhalofop-butyl 20%, sodium lignin sulfonate 5%, calcium lignosulfonate 7%, lauryl sodium sulfate 4%, soluble starch 1%, ammonium sulfate 4%, kaolin being complemented to 100% mixes; regulate pH value to 6.8 back comminution by gas stream with the pH regulator agent; after adding the water kneading; drop into again and carry out granulation in the comminutor, then drying, sieve required product.
Embodiment 2
The cyhalofop-butyl field efficacy is measured:
Cyhalofop-butyl water dispersible granules 75 gram/hectares with 20%, control rice direct-seeding Tanaka's weed moleplant seed (3 leaf phase), investigated dispenser respectively 7 days, after 15 days and 30 days to the control efficiency of moleplant seed, investigation result compares with contrast medicament a thousand pieces of gold (LG-DOW agricultural science company 10% cyhalofop-butyl missible oil), the results are shown in Table 1, the result shows that experimental pharmacy is suitable to the control efficiency of weed moleplant seed with the contrast medicament.
