Embodiment 1

[0022] Weigh 45% Pyrasulfotole, 15% flucarbasulfuron, 3% sodium dodecylbenzene sulfonate, 6% lignosulfonate, 3% carboxymethyl cellulose, kaolin and add to 100% by weight. The above raw materials are pre-mixed, air-jet milled, and post-mixed by conventional methods for preparing wettable powders to obtain the 60% Pyrasulfotole·flucarbasulfuron wettable powder.

Embodiment 2

[0024] Weigh 45% of Pyrasulfotole, 35% of flucarbasulfuron, 5% of sodium alkylnaphthalene sulfonate formaldehyde condensate, 2% of sodium lauryl sulfate, 5% of white carbon black, and diatomaceous earth to make up to 100% by weight. The above raw materials are pre-mixed, air-jet milled, and post-mixed by conventional methods for preparing wettable powders to obtain the 80% Pyrasulfotole·flucarbasulfuron wettable powder.

Embodiment 3

[0026] Weigh 25% Pyrasulfotole, 25% flucarbasulfuron, 3% alkyl sulfonate, 5% lignosulfonate, 3% polycarboxylate, 20% diatomaceous earth, light calcium to 100% by weight . The 50% Pyrasulfotole·fluzosulfuron water-dispersible granules can be obtained by subjecting the above-mentioned raw materials to the conventional method for preparing water-dispersible granules, ie mixing, ultrafine airflow pulverization, kneading, granulating, and drying.

Abstract

The invention relates to the pesticide technology field, and discloses a wheat field compound herbicide. The herbicide composition comprises two active components of Pyrasulfotole and flucarbazone-sodium, wherein, the weight ratio of the two active components is 1:16-16:1, and the mass percentage is 0.5-90% of the compound herbicide. The two active components of Pyrasulfotole and flucarbazone-sodium are compounded, by utilization of the complementarity of the two active components, the prevention effects on weeds are raised, and the shortages of single usage are covered. The herbicide composition not only can control wheat field gramineous weeds, but also can control broad leaf weeds, and has remarkable synergy effects. The herbicide composition not only has obvious weeding effects, but also is safe to wheat, has no influence on after-reap crops, and is an ideal herbicide.

Description

【Technical field】 [0001] The present invention relates to a herbicide composition for preventing and treating weeds in wheat fields, in particular to a herbicide for preventing and treating gramineous weeds and broad-leaved weeds in wheat fields, which is based on Pyrasulfotole and flucarbasulfuron-methyl Dual herbicide compositions of active ingredients. 【Background technique】 [0002] Wheat is the second largest grain crop in my country, accounting for 20-27% of the total area of ​​grain crops in the country, and its planting range covers almost all agricultural areas. In 2011, my country's wheat planting area was about 24 million hectares, with a total output of about 100 million tons. The area of ​​wheat weed damage accounts for about 30% of the planting area in my country, of which serious weed damage accounts for about 10%. Chemical control of weeds in wheat fields is an important measure to ensure wheat production. Since the introduction of 2,4-D in 1956, the use of...
