The invention discloses a paddy field weed control macro-granule containing pyrazosulfuron ethyl and quinclorac. The paddy field weed control macro-granule containing pyrazosulfuron ethyl and quinclorac comprises the following components in percentage by weight: 12-14% of quinclorac, 0.5-2.0% of pyrazosulfuron ethyl, 2-4% of silicon dioxide, 9-11% of oil substances, 1.5-5% of surface active agents, 20-30% of solid core materials, 20-30% of additives and the balance of a filler. The paddy field weed control macro-granule containing pyrazosulfuron ethyl and quinclorac uses floating material glass beads, so that the drug granules can float on the water and can freely disperse under the actions of wind power and the auxiliaries; the dispersing agent is added so that the active ingredients of the medicament can be dispersed to the whole paddy field within short time; the pesticide effect is permanent, and the labor and the time are saved. Compared with a quinclorac wettable powder single dosage, the paddy field weed control macro-granule has the advantages that the application amount of quinclorac is reduced so that the residue of the quinclorac in the soil is reduced, and phytotoxicity probably generated to subsequent crops is avoided.

Pyrazosulfuron-ethyl, clomazone and butachlor compound dispersible oil suspension concentrate and preparation method thereof

The invention provides a pyrazosulfuron-ethyl, clomazone and butachlor compound dispersible oil suspension concentrate and a preparation method thereof, relating to the technical field of control of weeds in direct sowing paddy fields. The pyrazosulfuron-ethyl, clomazone and butachlor compound dispersible oil suspension concentrate is prepared from 2 parts of pyrazosulfuron-ethyl, 8 parts of clomazone, 60 parts of butachlor, 2 parts of fatty alcohol-polyoxyethylene ether, 3 parts of styrylphenol polyoxyethylene ether, 2 parts of xanthan gum, 1 part of sodium benzoate, 2 parts of organic silicon and 20 parts of solvent oil by weight. The preparation method is characterized by pumping the raw materials into a preparation kettle, mixing and stirring the raw materials, then carrying out primary milling with a colloid mill, then finely milling with a sand mill, carrying out sampling analysis, and filtering, metering, packaging and warehousing after samples are qualified. The pyrazosulfuron-ethyl, clomazone and butachlor compound dispersible oil suspension concentrate achieves better control of annual grassy weeds, cyperaceous weeds and part of broadleaf weeds in the direct sowing paddy fields, and achieves united synergy of pyrazosulfuron-ethyl, clomazone and butachlor, thus achieving obvious synergistic effects; therefore mixing pyrazosulfuron-ethyl, clomazone and butachlor to control the annual grassy weeds, the cyperaceous weeds and part of the broadleaf weeds in the direct sowing paddy fields is feasible and is also necessary.

Rice field weed arrowhead preventing and control method

The invention discloses a rice field weed arrowhead preventing and control method. During first-time sealing, oxadiazon and pyrazosulfuron-ethyl are applied in a muddy water state by means of a bottle swing method in 5-7 days before rice transplantation and after rice field water-containing soil preparation, a water layer of 3-5 cm is kept, rice seedlings are transplanted in 5-7 days after pesticide application, water draining is not performed within 48 hours after pesticide application, and a water layer of 3-5 cm is kept; during second-time sealing, pyrazosulfuron-ethyl and bensulfuron methyl are mixed with a fertilizer or sandy soil to be applied in 10-15 days before rice transplantation, a field water layer of 3-5 cm is kept for 5-7 days; at an active tillering stage of growing rice and when each wild arrowhead seedling has 5-7 leaves, a bentazone aqueous solution and pyrazosulfuron-ethyl are evenly sprayed in a field, field water is completely drained before pesticide application, water is returned within 1-2 days after pesticide application and is kept for 3-5 days; at a booting earlier stage of the rice, new bulbs of arrowheads doe not grow out, artificial pond clearing is conducted at the moment, and arrowheads are pulled out. By means of the rice field weed arrowhead preventing and control method, arrowhead preventing and control effect is improved, the arrowheads are basically eliminated within 3 years, and yield is improved.

Method for using pyrazosulfuron-ethyl molecularly imprinted polymer for analyzing sulfonylurea herbicide and application thereof

The invention relates to a method for using pyrazosulfuron-ethyl molecularly imprinted polymer for analyzing sulfonylurea herbicide. The method includes the steps of molecularly imprinted solid-phase extraction (MISPE) column preparation, herbicide standard material stock solution preparation, herbicide high performance liquid chromatography (HPLC) standard curve drawing, sample purification solution preparation, HPLC analysis of a sample to be analyzed and the like. A sulfonylurea derby solid-phase extraction column used by the method can specially adsorb various analogues of sulfonylurea derby and the like. The method has remarkable selectivity, flow velocity is increased by 50%, analysis time is reduced by 50%, template compound residual amount is almost zero, and false positive caused by residual template compound is avoided. The solid-phase extraction column is remarkable in purification effect, simplifies enrichment and purification of the sample, improves pre-processing efficiency, and can be reused. A detection method combining a molecularly imprinted solid-phase extraction column and an HPLC instrument can be built, and finally a standard detection method of biological samples of agricultural products, water, soil and the like can be built.
