Abstract
The invention relates to a water dispersion granule of thiophanate methyl, which has an effective ingredient of thiophanate methyl. The water dispersion granule of thiophanate methyl comprises the following components by weight ratio: 40% - 80% of thiophanate methyl raw powder, 2% - 8% of wetting agent, 3% - 10 % of dispersant, 1% - 20% of disintegrating agent, 5% - 40% of carrier and 2% - 10% of stabilizing agent. The method overcomes the technical problem existed in the original water dispersion granule of thiophanate methyl, the invention has the advantages of convenient storage and transportation; the binder is avoided using so that the product quality is greatly raised, the drug effect can be improved by more than 20% and the usage period of the product is increased by the stabilizing agent.
Description
Technical field
The present invention relates to a kind of pesticidal preparations, specifically be meant the water dispersible granules that contains thiophanate-methyl.
Background technology
At present, one of bactericide that thiophanate-methyl is commonly used has the bactericidal activity height, and security performance is good, the characteristics that fungicidal spectrum is wide.Being made generally in wetting powder and suspending agent uses.Wetting powder dust pollution in processing and use is serious, and environment and health are had very big harm, and shortcomings such as effective rate of utilization is low, lasting period weak point; Though suspending agent is the environmental protection preparation, high to the process conditions requirement aborning, can not realize the preparation of high-load at present, and its production, packing and cost of transportation are also higher, thereby cause the increase of production and use cost.
Water dispersible granules is a kind of pesticides new formulation that grows up the eighties in 20th century, is the more comprehensive and more perfect product of combination property in the current pesticidal preparations, has the advantage of solid pharmaceutical preparation (granula and wetting powder) and liquid preparation (suspending agent etc.).Patent documentation 1 (200410026344.6) relates to a kind of water dispersible granules of thiophanate-methyl, contain binding agent in its component, be convenient to be shaped, but because the adhesive effect of binding agent, cause that the product dispersion effect is poor, drug effect is difficult to good performance, also have product, easily problem such as inefficacy poor at shelf life stability.
Summary of the invention
The technical problem to be solved in the present invention is the defective that overcomes prior art, and a kind of binding agent that do not contain is provided, dispersion effect is good, good stability the water-dispersible grain agent prescription.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The water dispersible granules of thiophanate-methyl, its effective ingredient are thiophanate-methyl, and its component and weight proportion are: the former powder of thiophanate-methyl: 40%～80%; Wetting agent: 2%～8%; Dispersant: 3%～10%; Disintegrant: 1%～20%; Carrier: 5%～40%; Stabilizing agent: 2%～10%.
Described wetting agent is any or the arbitrarily combination in phenethyl phenol polyethenoxy ether condensation product, alkylphenol polyoxyethylene formaldehyde condensation products, sodium alkyl benzene sulfonate, sodium alkyl sulfate, alkyl phosphoric acid sodium, phenethyl phenol polyethenoxy ether sodium sulfate and the alkylphenol-polyethenoxy base sodium sulphate.
Described dispersant is Fluhyzon formaldehyde condensation products sodium sulfonate, alkylphenol formaldehyde condensation product sodium sulphate, sodium lignin sulfonate, to any or combination arbitrarily in methoxyl group fatty acyl amido benzene sulfonic acid sodium salt and the polycarboxylic acids sodium.
Described disintegrant is any or the arbitrarily combination in bentonite, Attapulgite, calgon, inorganic sodium and the white carbon.
Described carrier is any or the arbitrarily combination in kaolin, precipitated calcium carbonate, diatomite and the potter's clay.
Described stabilizing agent is any or the arbitrarily combination in epoxy linseed oil, antodyne and the epoxidised soybean oil.
The preparation of above-mentioned water dispersible granules can be adopted manufacturing process such as extruder grain, technology simple controllable; Prescription of the present invention has overcome the technical barrier that former methyl thiophanate water dispersible granules exists, the storage convenient transportation; Avoided the use of binding agent, product quality improves a lot, and drug effect improves more than 20%, and stabilizing agent has increased the life cycle of product.
