Description

Granule containing sulfonylurea herbicide and preparation method thereof
Technical Field
The invention belongs to the field of pesticide formulation processing, and in particular relates to granules taking sulfonylurea herbicides as active ingredients and a preparation method thereof.
Background
Sulfonylurea herbicides were first discovered by dupont to be a sign of herbicide entry into the ultra-high efficacy period. Is suitable for wheat, rice, corn, soybean, rape, etc. The sulfonylurea herbicide has the main characteristics that: first, the activity is extremely high, the dosage per hectare is calculated in grams, and the pesticide belongs to the super-efficient pesticide variety. Second, the weeding spectrum is wide, and the weeding spectrum of each variety has larger difference. Thirdly, the selectivity is strong, and each variety has corresponding applicable crops and weeding spectrums. Fourth, the use is convenient, the medicament can be absorbed by roots, stems and leaves of weeds, and can be used for soil treatment and stem and leaf treatment. Fifth, it is safe to mammals and is easily decomposed in the environment so as not to be easily accumulated.
The pesticide Granule (GRnule) is a granular preparation consisting of pesticide raw material, auxiliary agent and carrier. As a commonly used pesticide formulation there are many advantages: when the pesticide is applied, the pesticide particles are not attached to the stems and leaves of crops, so that the direct contact is avoided to generate phytotoxicity; the adhesion or inhalation dosage of the body of an operator can be reduced in the process of drug administration, and poisoning accidents are avoided; so that the high-toxicity pesticide is low in toxicity and can avoid poisoning of people and animals.
Because sulfonylurea herbicides are unstable in water and organic solvents, most sulfonylurea herbicides are processed into solid dosage forms such as granules, wettable powders and the like. In the intensive research process of the granules containing sulfonylurea herbicides, the inventor finds that if the conventional preparation method of granules containing sulfonylurea herbicides is adopted to prepare the granules containing sulfonylurea herbicides by mixing and crushing the raw material and the auxiliary agent filler into the mother powder and adding the adhesive to coat the mother powder on the granule carrier, the thermal storage decomposition rate of sulfonylurea active ingredients is higher, the sample dust amount is larger, the wear resistance is poorer, and the quality of the product is seriously affected. And because the dust amount is large, the phenomenon of drifting of active ingredients is easy to occur when the anti-pesticide is applied on the fly, so that the phenomena of phytotoxicity such as yellowing and falling of leaves of non-target plants planted around farmlands occur. Aiming at the problems, the inventor performs a formulation and preparation process investigation test of granules containing sulfonylurea herbicides.
Disclosure of Invention
The invention aims to provide granules containing sulfonylurea herbicides and a preparation method thereof, so as to reduce the heat storage decomposition rate of sulfonylurea herbicides, reduce the dust content of products, improve the wear resistance and solve the phytotoxicity phenomenon of the products on non-target plants planted around farmlands during the pesticide application of the products.
In order to achieve the above purpose, the technical scheme of the invention is as follows:
the preparation method of granule containing sulfonylurea herbicide includes mixing the effective components of sulfonylurea herbicide with water soluble assistant and water, shearing, and sand grinding to obtain slurry; and (3) fully mixing the sanded slurry with carrier particles, adding filler, fully mixing, and drying to obtain granules containing sulfonylurea herbicides.
The active ingredients in the granules containing sulfonylurea herbicides account for 0.01-20% of the mass of the preparation; wherein, the sulfonylurea herbicide is selected from one or more of bensulfuron methyl, pyrazosulfuron ethyl, nicosulfuron, cinosulfuron, thifensulfuron methyl, chlorimuron ethyl, tribenuron methyl, mesosulfuron methyl, ethoxysulfuron, cinosulfuron, flupyrsulfuron-methyl and formaminosulfuron-methyl; the compound A is selected from one or more of quinclorac, mefenacet, oxyfluorfen, cyhalofop-butyl, oxadiazon, bispyribac-sodium, penoxsulam, 2-methyl-4-chloro, alachlor, acetochlor, pretilachlor, butachlor, carfentrazone-ethyl, prometryn, pendimethalin, simetryn, bentazone, pyriftalid and anilofos.
The auxiliary agent is one or more of dispersing agent, wetting agent, filler and carrier; wherein the dispersing agent is sodium lignin sulfonate, calcium lignin sulfonate, polycarboxylate and alkyl naphthalene sulfonate formaldehyde condensate; the wetting agent is one or more of alkyl sulfate, alkyl sulfonate and naphthalene sulfonate.
The sulfonylurea herbicide-containing granule comprises the following components in percentage by weight: 0.01-10% of one or more sulfonylurea herbicides, 0.01-10% of one or more compounds A, 0.01-5% of dispersing agent, 0.01-5% of wetting agent, 1-20% of filler and the balance of carrier.
The filler is selected from one or a combination of a plurality of calcined kaolin, light calcium carbonate, diatomite and white carbon black.
The carrier is selected from one or more of silicate particles, urea particles, starch particles, ammonium sulfate particles, ammonium nitrate particles, ammonium chloride particles, potassium sulfate particles and humic acid particles.
The granules containing sulfonylurea herbicide are prepared by the method, and the heat storage decomposition rate of active ingredients in the granules is reduced, the dust amount is reduced, and the dust drift generated during application is reduced.
The granule can be applied by adopting a direct spraying and airplane spraying mode.
The invention has the advantages that:
the granules containing sulfonylurea herbicides are prepared by adopting a preparation process that the active ingredients are ground into suspending agents to be coated on carrier particles, and then fillers are added for full mixing, so that the thermal storage decomposition rate of sulfonylurea herbicides in the granules containing sulfonylurea herbicides can be reduced, the dust amount is reduced, the wear resistance is improved, the dust drift generated when the granules containing sulfonylurea herbicides are subjected to the flying prevention and pesticide application is greatly reduced, and the phytotoxicity phenomenon of non-target plants planted around farmlands during the flying prevention and pesticide application is further solved.

As can be seen from the data in Table 1, the sulfonylurea herbicide granule samples prepared by the preferred formulation and process of the present invention have a sulfonylurea active ingredient heat storage decomposition rate which can be reduced to below 5% and is significantly lower than that of other samples prepared by conventional coating processes. The dust content can be reduced to 2-5mg. The abrasion resistance is also better than samples prepared by other processes. Compared with the sample prepared by the conventional coating process, the heat storage decomposition rate, the dust amount and the wear resistance index of the active ingredients are obviously improved.

6. Investigation of test results
The investigation method comprises the following steps: investigation was performed by using a diagonal three-point sampling method, 3 sampling points were taken per treatment, each sampling point having an area of 0.25m 2 (0.5 m.times.0.5 m), the types of weeds were examined and described, and the number of weeds was examined. The control effect of each parallel group was calculated using the following formula: weed plant control = 100% × (control zone weed number (CK) -treatment zone weed number) per treatment zone weed number, overall control is the mean control for each parallel group, and for ease of description, weed number is expressed as weed stalk number. And evaluating the phytotoxicity of the trees around the farmland by visual inspection, and if the phenomena of yellowing and falling of the tree around the farmland are not found to be phytotoxicity, the phenomena of yellowing and falling of the tree around the farmland are not found to be phytotoxicity.
