Embodiment 1

[0053] Weigh 10% oxazimone, 15% pretilachlor, 5% agricultural milk 700#, 5% sodium polycarboxylate, 3% ethyl acetate, 1% propylene glycol, 1% silicone defoamer, 1% poly Ethylene glycol and deionized water are added to 100% by weight. The above-mentioned raw materials are uniformly mixed through high-speed shearing, and then ball-milled in a ball mill for 2 to 3 hours to make the particle diameters below 5 μm to prepare a 25% oxazimone·preichlor suspoemulsion.

Embodiment 2

[0055] Weigh 35% oxazimone, 10% pretilachlor, 5% agricultural milk 2201, 5% sodium lignosulfonate, 3% methyl benzoate, 2% glycerin, 1% silicone oil, 1% white carbon black, Deionized water is added to 100% by weight. The above-mentioned raw materials are uniformly mixed through high-speed shearing, and then ball-milled in a ball mill for 2 to 3 hours to make the particle diameters below 5 μm to prepare 45% oxazimone·preichlor suspoemulsion.

Embodiment 3

[0057] Weigh 10% oxazimone, 25% pretilachlor, 5% linseed oil, 3% benzyl dimethyl phenol polyoxyethyl ether, 5% gum arabic, 8% calcium alkylbenzene sulfonate, 1 % Organosilicon defoamer, 3% sodium hydroxide and hydrochloric acid, and deionized water is added to 100% by weight. The active ingredient, the polymer capsule wall material, and the solvent are mixed into a homogeneous oil phase, the oil phase is added to the water phase solution, and after shearing, dispersion, solidification, a 35% oxazimone·precachlor microcapsule suspension is prepared.

Abstract

The invention discloses a weeding composite comprising oxaziclomefone and application of the weeding composite. The composite comprises a first active ingredient, namely the oxaziclomefone, a second active ingredient, namely pretilachlor or butachlor, and assistants. The weight ratio of the first active ingredient to the second active ingredient is (0.1-100): (10-150). The composite can be prepared into suspoemulsion, micro-capsule suspending agent, aqueous suspension agent, dispersible oil suspending agent, missible oil, microemulsion, emulsion in water, wettable powder, water dispersible granules and granules which are allowable agriculturally. The weeding composite is reasonable in composition, good in weeding effect and low in dosage cost, and activity and weeding effect of the composite are not simple superposition of component activity. Compared with existing single preparations, the weeding composite has the advantages of remarkable weeding effect and synergistic effect, high safety and conformity with safety requirements of pesticide preparations. The weeding composite is used for early-stage weeding of transplant fields and direct seedling fields and has high activity for weeds of paddy fields.

Description

Technical field [0001] The invention relates to a paddy field weeding composition, which is composed of active ingredients oxazimone, pretilachlor or butachlor and additives, and belongs to the technical field of compound pesticides. Background technique [0002] Oxaziclomefone, also known as oxaziclomefone, chemical name 3-[1-(3.,5-dichlorophenyl)-1-methylethyl]-2,3-dihydro-6 -Methyl-5-phenyl-4H-1,3-oxazin-4-one. It belongs to the organic heterocyclic group and is a systemic and conductive paddy field herbicide, mainly absorbed by the roots and stems and leaves of weeds. The stems and leaves of the weeds become green and stop growing until they die. It is suitable for long application period, long lasting effect, high safety for rice selection, and control of barnyardgrass, stephanotis, duck's diffusa, sedge and other weeds. [0003] Pretilachlo, English name pretilachlo, chemical name 2-chloro-2',6'-diethyl-N-(2-propoxyethyl) acetanilide, amide herbicide, mechanism of action i...
