Abstract

The invention relates to an effervescent granule containing pyrazosulfuron-ethyl and ANILOFOS and a preparation method thereof. The adopted technical scheme is: the pyrazosulfuron-ethyl and the ANILOFOS are the active ingredients, besides, by weight percentage, the granule consists of the following ingredients: 1-15% of the pyrazosulfuron-ethyl, 3-50% of the ANILOFOS, 1.5-25% of sorbent, 6-30% of addition agent, 6-30% of filler, 3-10% of vegetable oil, as well as 6-25% of disintegrant; the preparation method is as follows: the ANILOFOS is put in a temperature control drying cabinet, the temperature is controlled to be 50-70 DEG C, and the melted ANILOFOS is fully mixed with the sorbent according to the rate of 2:1 to obtain the parent powder of the ANILOFOS; according to the mixture ratio, the parent powder, the pyrazosulfuron-ethyl, the addition agent, the filler and the disintegrant are taken and thrown into a mixer for superfine comminution; and the medicines are fully mixed with the vegetable oil to fabricate the granule by screw extrusion. The invention has the advantages of broad grass removal spectrum, lower manufacturing cost and use cost, convenient use, no pollution to the environment and good safety.

Description

Technical field: [0001] The invention relates to a pesticide, in particular to an effervescent granule containing effective ingredients pyrazosulfuron-methyl and saponin-methyl and a preparation method thereof for weeding in paddy fields. Background technique: [0002] Pyrazosulfuron-ethyl (pyrazosulfuron-ethyl), chemical name: 5-(4,6-dimethoxypyrimidinyl-2-carbamoylsulfamoyl)-1-methylpyrazolyl-4-carboxylic acid ethyl ester , molecular formula: C 14 h 18 N 6 o 7 S, structural formula: [0003] [0004] Pyrazosulfuron-methyl is a high-efficiency sulfonylurea selective rice herbicide. The active ingredients can quickly diffuse in water, be absorbed by the roots of weeds and then transfer to the plants, hindering the synthesis of amino acids. Rapidly inhibits the growth of weed stems and leaves and the extension of roots, and then dies completely. Safe for rice. The herbicidal spectrum is relatively wide, and the control effect on broad-leaved weeds, sedge weeds, and...
