Embodiment 1

[0086] Weigh 20% oxfenacet, 5% oxazimone, 3% TERSPERSE 2700 (polycarboxyl hydrochloride, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde composition) , 1% BX (sodium dibutyl naphthalene sulfonate), 1% K-12 (sodium lauryl sulfate), 3% soluble starch, 3% glucose, and kaolin are added to 100% by weight. The above-mentioned raw materials are prepared by conventional methods for preparing water-dispersible granules, namely mixing, ultra-fine jet pulverization, mixing, and granulation steps to prepare 25% oxadifen·oxadifen-oxachlor water-dispersible granules.

Embodiment 2

[0088] Weigh 12% oxadifen, 12% oxadifen, 3% TERSPERSE 2700, 4% sodium lignosulfonate, 1% open powder BX, 1% K-12, 1% carboxymethyl cellulose , 3% urea and diatomaceous earth are added to 100% by weight. The above-mentioned raw materials are prepared by conventional methods of preparing water-dispersible granules, namely mixing, ultra-fine jet pulverization, mixing, and granulation steps to prepare 24% oxadifen·oxadifen-oxachlor water-dispersible granules.

Embodiment 3

[0090] Weigh 8% oxaflufen, 30% oxazimone, 4% TERSPERSE 2700, 1% open powder BX, 1% K-12, 0.8% dextrin, 5% ammonium sulfate, attapulgite and add to 100% parts by weight. The above-mentioned raw materials are prepared by conventional methods for preparing water-dispersible granules, namely mixing, ultra-fine jet pulverization, mixing, and granulation steps to prepare 38% oxadifen·oxadifen-oxachlor water-dispersible granules.

[0091] Formulation Example Four

[0092] Weigh 10% oxaflufen, 2.5% oxazimone, 4% Morwet D-425 (alkyl naphthalene sulfonate, produced by Akzo Nobel), 3% diffusing agent NNO, 2% spreading powder BX, 2% K-12, 2% polyvinylpyrrolidone, 0.5% xanthan gum, and kaolin are added to 100% by weight. The above-mentioned raw materials are prepared by the conventional method of preparing water dispersible granules, namely mixing, ultra-fine jet pulverization, mixing, and granulating steps to prepare 12.5% ​​oxadifen·oxadifen-oxachlor water dispersible granules.

Abstract

The invention discloses a herbicide composition containing oxaziclomefone and metamifop. The herbicide composition comprises the active ingredients of oxaziclomefone and metamifop; the mass ratio of oxaziclomefone to metamifop is 19:1 to 1:19, and is preferably 4:1 to 1:4. The accumulation quantity of the oxaziclomefone and the metamifop is 0.1 percent to 80 percent of the total weight of the composition, and is preferably 2 percent to 20 percent. The herbicide composition has the advantages that the ingredients are reasonable; the prevention effect is superior to the activity of each ingredient during the single application; the synergistic effect is achieved; the weed prevention and control spectrum is expanded; the paddy field gramineae weed, cyperaceae weed and broadleaf weed can be prevented and removed through once medication; the number of medication times is reduced; the prevention and control cost is reduced; the generation of the weed resistance is retarded; the safety on the crops is high; the safety requirements of the pesticide preparation are met.

Description

Technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a herbicide composition containing oxazimone and oxadifen, which is used for controlling annual weeds and barnyard grasses in rice fields and weeds in corn fields It is a dual herbicide composition composed of oxazimione and oxadifen. Background technique [0002] With the continuous use of many herbicides in large-scale rice fields, many problems have also arisen: ①Weed resistance is outstanding. Among them, barnyardgrass is more resistant to propanyl, butachlor, and butachlor. Recently, Common weeds such as Cyperaceae, Yujiuhuaceae, Alismaaceae and other common weeds such as heteromorphic cyperus, firefly, wild sedge, Yujiuhua, and Diffusae have developed resistance to sulfonylurea herbicides, making weeding problems more difficult. More complicated. ②The harm of perennial weeds has become an important issue, especially the perennial weeds of Cyperaceae are more pro...
