Embodiment 1

[0027] Weigh 10% sulfasulfuron-methyl, 70% flucarbasulfuron-methyl, 2% TERSPERSE 2700, 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 1% pull-off powder BX (dibutyl naphthalene sulfonate sodium lauryl sulfate), 1% K-12 (sodium lauryl sulfate), 1% carboxymethyl cellulose, and diatomaceous earth are added to 100% by weight. 80% sulfasulfuron-flucarbasulfuron water-dispersible granules were prepared by the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

Embodiment 2

[0029] Weigh 25% sulfasulfuron-methyl, 25% flucarbasulfuron-methyl, 4% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO, 2% pull-off powder BX, 2% K -12. 3% cornstarch, 5% ammonium sulfate, and attapulgite are added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, namely mixing, ultra-micro airflow pulverization, mixing, and granulation to prepare 50% sulfasulfuron-flucarbasulfuron water-dispersible granules.

Embodiment 3

[0031] Weigh 6% sulfasulfuron, 60% flucarbasulfuron, 4% calcium lignosulfonate, 3% TERSPERSE 2700, 2% pull open powder BX, 2% K-12, 3% white carbon black, light calcium Add to 100% by weight. The above raw materials were mixed and jet milled to obtain 66% sulfasulfuron-flucarbasulfuron wettable powder.

Abstract

The invention discloses a wheat paddock weeding composition containing sulfosulfuron and flucarbazone. The active ingredients of the wheat paddock weeding composition are sulfosulfuron and flucarbazone respectively, wherein the weight ratio of the sulfosulfuron to the flucarbazone is 1:10-10:1, and the wheat paddock weeding composition can be prepared into agriculturally allowable water dispersible granule, wettable powder, a suspending agent and a dispersible oil suspending agent. The wheat paddock weeding composition disclosed by the invention is reasonable in components, good in weeding effect and low in medication cost, and activity and weeding effect of the wheat paddock weeding composition are not simple addition of the activity and weeding effect of each component; and compared with the existing single preparation, the wheat paddock weeding composition disclosed by the invention has an obvious synergistic effect besides an obvious weeding effect, is good in safety, accords with safety requirements of pesticide preparation and has higher weeding activity to wheat paddock weeds.

Description

technical field [0001] The invention relates to a wheat field herbicide composition, the active ingredients are sulfasulfuron-methyl and flucarbasulfuron-methyl, and belong to the technical field of compound pesticides. Background technique [0002] Sulfosulfuron, English common name Sulfosulfuron, chemical name: 1-(4,6-dimethoxypyridin-2-yl)-3[(2-ethylsulfonyl-imidazo[1,2-a]pyridine) Sulfonyl]urea. Sulfsulfuron-methyl is a new type of sulfonylurea herbicide, which can selectively control a variety of weeds in wheat fields, and has a good control effect on annual grass weeds and broad-leaved weeds, such as wild oats, bluegrass, Polygonum , Kan Mai Niang, Zhu Zai, etc. [0003] Flucarbazone-methyl, also known as Biaohu, English name: Flucarbazone-Na, chemical name: 1H-1,2,4-triazole-1-carbamoyl-4,5-2H-3-methoxy-4 -Methyl-5-O-N-[[2-(trifluoromethoxy)benzene]sulfonyl]-sodium salt. Flucarbasulfuron is a sulfonylurea systemic high-efficiency herbicide for wheat fields. Its ac...
