Embodiment 1

[0018] Weigh 1% rimsulfuron-methyl, 5% mesotrione, 50% atrazine, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 2% diffusing agent NNO (alkylnaphthalene sulfonate) salt formaldehyde condensate), 1% pull open powder BX (sodium dibutylnaphthalene sulfonate), 1% K-12 (sodium dodecyl sulfate), 2% white carbon black, 5% ammonium sulfate, diatom Soil is added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 56% rimsulfuron-mesotrione-atrazine water-dispersible granules.

Embodiment 2

[0020] Weigh 1.2% rimsulfuron-methyl, 8% mesotrione, 50.8% atrazine, 4% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 3% sodium lignosulfonate, 3% Pull apart powder BX (sodium dibutylnaphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% white carbon black, 5% urea, 5% corn starch, attapulgite to 100% parts by weight. 60% rimsulfuron-mesotrione-atrazine water-dispersible granules were prepared by the conventional method for preparing water-dispersible granules from the above raw materials, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

Embodiment 3

[0022] Weigh 0.8% rimsulfuron-methyl, 16% mesotrione, 63.2% atrazine, 5% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 2% diffusing agent NNO (alkylnaphthalene sulfonate) salt formaldehyde condensate), 2% pull open powder BX (sodium dibutyl naphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 1% carboxymethyl cellulose, 5% glucose, kaolin Add to 100% by weight. 80% rimsulfuron-mesotrione-atrazine water-dispersible granules were prepared by the conventional method for preparing water-dispersible granules from the above-mentioned raw materials, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

Abstract

The invention relates to a herbicide composition for preventing and removing weeds in farmland, which is a ternary herbicide prepared by using rimsulfuron, nitrate sulcotrione and atrazine as activity, wherein the weight ratio of the imsulfuron, the nitrate sulcotrione and the atrazine is (1-1.6) to (1-80) to (8-640), and the preferable weight ratio is (1-1.6) to (2.5-20) to (10-160). The cumulant of the imsulfuron, the nitrate sulcotrione and the atrazine is 5-90% of the total weight of the composition. The herbicide composition has the advantages of reasonable components, good weed removingeffect, weed control spectrum expanding, the number of application reducing, control cost lowering, the generation of weed resistance slowing and good safety for crops, and meets the security requirements of pesticide formulations. The herbicide composition has a good control effect for grassy weeds and broad-leaved weeds in corn fields.

Description

technical field [0001] The invention relates to a cornfield herbicide composition, in particular to a herbicide for preventing and treating gramineous weeds and broad-leaved weeds in cornfields, which is composed of rimsulfuron-methyl, mesotrione and atrazine active ingredients agent composition. Background technique [0002] Rimsulfuron English common name rimsulfuron, molecular formula C 14 h 17 N 5 o 7 S 2 , chemical name 1-(4,6-dimethoxypyrimidin-2-yl)-3-(3-ethylthio-2-pyridylthio)urea. Trisulfuron-methyl is an amino acid compound inhibitor that arrests cell differentiation and plant growth by inhibiting the biosynthesis of essential valine and isoleucine. Absorbed by roots and leaves, it is quickly transmitted to meristems. The drug can effectively control most annual and perennial weeds in corn fields, and can also be used in potato and tomato fields. [0003] Mesotrione English common name mesotrione, molecular formula C 14 h 13 NO 7 S, chemical name 2-(2-n...
