Embodiment 1

[0046] Weigh 15% bicyclic sulcotrione, 25% diflufenican, 4% polyoxyethylene polyoxypropylene ether block copolymer, 2% pull-off powder BX (sodium dibutylnaphthalene sulfonate), 2% Sodium dodecyl sulfonate, 3% talcum powder, light calcium added to 100% by weight. The above-mentioned raw materials are mixed and air-jet milled to obtain 40% bicyclic sulcotrione · diflufenican wettable powder.

Embodiment 2

[0048] Weigh 20% bicyclic sulcotrione, 10% diflufenamide, 4% calcium polycarboxylate, 2% fatty alcohol polyoxyethylene ether phosphate, 2% sodium lauryl sulfate, 3% white carbon black, Diatomaceous earth is added to 100% by weight. The above-mentioned raw materials were mixed and air-jet milled to obtain 30% bicyclic sulcotrione·diflufenamide wettable powder.

Embodiment 3

[0050] Weigh 10% bicyclic sulcotrione, 30% diflufenican, 2% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate ), 1% pull open powder BX (sodium dibutylnaphthalene sulfonate), 1% sodium alkylsulfonate, 1% glucose, and talcum powder added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, namely mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 40% bicyclic sulcotrione·diflufenamide water-dispersible granules.

Abstract

The invention discloses a benzobicyclon-containing herbicidal composition and application of the benzobicyclon-containing herbicidal composition. The benzobicyclon-containing herbicidal composition isprepared from the benzobicyclon as a first active component, diflufenican as a second active component and an additive, wherein the weight ratio of the first active component to the second active component is (1 to 90)-(90 to 1), preferably (1 to 50)-(50 to 1), more preferably (1 to 25)-(25 to 1), and most preferably (1 to 10)-(10 to 1). The composition can be prepared into agriculturally allowable wettable powder, water dispersible granules, suspension concentrates, dispersible oil-based suspensions, granules, fine granules, macro granules, effervescent granules, effervescent tablets and spreading oil. The benzobicyclon-containing herbicidal composition provided by the invention has excellent prevention and control effect to northeastern transplanting rice, direct seeded rice, dry directed-seed rice, machine-transplanted seedlings, barnyard grasses in artificial rice transplanting field, rice barnyard grasses, moleplant seeds, paspalum paspaloides, crab grasses, Leersia oryzoides, sagittaria trifolia, sagittaria pygmaea, monochoria vaginalis, rhizoma alismatis and scirpus juncoides, particularly has obvious synergic effect to the barnyard grasses, the rice barnyard grasses, the moleplant seeds, sagittaria trifolia and the scirpus juncoides, can lower the use cost, delays the resistance and is high in safety to crops.

Description

technical field [0001] The invention relates to a paddy field herbicidal composition, which is composed of active ingredients bicyclosulfotrione, diflufenican and auxiliary agents, and belongs to the technical field of compound pesticides. Background technique [0002] Bicyclic sulcotrione, English name benzobicyclon, a triketone herbicide developed by Japan SDS Bioscience Co., Ltd., HPPD inhibitor, is effective against grass weeds, broad-leaved weeds and sedges in paddy fields. Soil treatment can effectively control weeds in paddy fields such as barnyardgrass, firefly rush, bermudagrass, dwarf sagittarius, and false rice. Only high doses of dwarf sagittarius can achieve the ideal control effect, and the effective period can reach 6 weeks. This compound is currently The only pesticide in the world that can be used on rice and is effective on pseudo-rice. [0003] Diflufenican, English name diflufenican, chemical name: N-(2,4-difluorophenyl)-2-(3-trifluoromethylphenoxy)-3-py...
