Embodiment 1

[0026] Example 1: 64% emulsifiable concentrate

[0027] The formula is composed of: 8% of active ingredient A, 56% of active ingredient B, 5% of emulsifier alkylphenol polyoxyethylene ether, 4% of emulsifier dioctyl sulfosuccinate sodium salt, and 100% of solvent xylene .

[0028] The preparation method is as follows: put all the materials into the batching kettle, stir and dissolve until completely transparent, and transfer to the storage tank for filling after passing the test.

Embodiment 2

[0029] Embodiment 2: 30% suspending agent

[0030] The formula is composed of: 3% active ingredient A, 27% active ingredient B, 4% wetting agent sodium lauryl sulfate, 3% dispersant sodium naphthalenesulfonate formaldehyde condensate, 5% antifreeze propylene glycol, thickener yellow Raw gum 0.2%, water make up to 100%.

[0031] The preparation method is: put the active ingredient, wetting agent, dispersant, antifreeze and water into the stirring tank, after fully stirring, pump the material into the sand mill for full grinding, after the grinding is completed, pump it into the high-speed shearing machine In the process, after adding the thickener, high-speed shearing is carried out, and the suspending agent is obtained after the shearing is completed.

Embodiment 3

[0032] Example 3: 72% water dispersible granules

[0033] The formula is composed of: active ingredient A is 60%, active ingredient B is 12%, wetting agent pulls apart powder 4%, dispersant polycarboxylate 6%, disintegrant ammonium sulfate 5%, binder polyvinyl alcohol 0.5% %, filler diatomaceous earth to make up to 100%.

[0034] The preparation method is as follows: after all the materials are mixed uniformly, pulverized by an airflow mill, mixed uniformly again, and then a certain amount of water is added to knead the mixture, extruded and granulated, and dried and sieved to obtain the water-dispersible granules.

Abstract

The invention provides synergistic herbicidal composition containing pinoxaden and saflufenacil. The herbicidal composition is characterized by comprising an active ingredient A and an active ingredient B, wherein the active ingredient A contains pinoxaden and saflufenacil, and the active ingredient B is any one of or a combination of more of pyraflufen-ethyl, diflufenican, isoproturon, flufenacet, bromoxynil octanoate, indanofan, pyroxasulfone, flupoxam and MCPA-2 ethylhexyl ester. Besides, the herbicidal composition also comprises an aid which can be used during processing of a pesticide preparation. The herbicidal composition can be prepared into conventional pesticide preparations and applied to control of unnecessary plants in a wheat field.

Description

technical field [0001] The invention belongs to the technical field of pesticide application, and relates to a pesticide composition, in particular to a herbicidal composition containing pinoxaden and saflufenacil, which is applied to control unwanted plants in wheat fields. Background technique [0002] During wheat production, unwanted plants (weeds) occur heavily, seriously endangering wheat growth. The types of weeds in the wheat field are very different from those in other crop fields. For example, the weeds that occur seriously in the wheat field are mainly: pig scorpion, Artemisia solani, shepherd's purse, chickweed, wheat bottle grass, Maijiagong, big Broad-leaved weeds such as nest vegetables, as well as gramineous weeds such as wild oats, oatmeal, brome, poisonous wheat, ryegrass multiflora, knotty wheat, hard grass, soda grass, sage grass, and candle grass. There are few grasses in other crop fields where broad-leaved weeds such as retroflexus, purslane, velvetle...
