Embodiment 1

[0021] In this embodiment, the following wettable powder containing acifluorfen is applied to weed control: the wettable powder includes: active ingredient 18wt%, sodium naphthalenesulfonate formaldehyde condensate 8wt%, polycarboxylate 1.5wt%, fatty alcohol poly 2wt% of oxyethylene ether, 1.5wt% of sodium lauryl sulfate, 3wt% of white carbon black and the balance of bentonite. Wherein, the active ingredients include, in parts by weight, 20 parts of fluorfen-ethyl, 30 parts of flumesulfuron, 20 parts of butazoturon, 40 parts of pendimethalin and 40 parts of mesotrione. After the above-mentioned raw materials are mixed evenly in a double-helix conical mixer, they are pulverized by a jet mill and made into a powder shape.

Embodiment 2

[0023] In this embodiment, the following wettable powder containing acifluorfen is applied to weed control: the wettable powder includes: active ingredient 18wt%, sodium naphthalenesulfonate formaldehyde condensate 8wt%, polycarboxylate 1.5wt%, fatty alcohol poly 2wt% of oxyethylene ether, 1.5wt% of sodium lauryl sulfate, 3wt% of white carbon black and the balance of bentonite. Wherein, the active ingredients include, in parts by weight, 20 parts of fluorfen-ethyl, 15 parts of pyrimsulfuron, 25 parts of tetrazouron, 30 parts of pendimethalin and 50 parts of mesotrione. After the above-mentioned raw materials are mixed evenly in a double-helix conical mixer, they are pulverized by a jet mill and made into a powder shape.

Embodiment 3

[0025] In this embodiment, the following wettable powder containing acifluorfen is applied to weed control: the wettable powder includes: active ingredient 18wt%, sodium naphthalenesulfonate formaldehyde condensate 8wt%, polycarboxylate 1.5wt%, fatty alcohol poly 2wt% of oxyethylene ether, 1.5wt% of sodium lauryl sulfate, 3wt% of white carbon black and the balance of bentonite. Wherein, the active ingredients include, in parts by weight, 20 parts of fluorfen-ethyl, 40 parts of pyrimsulfuron, 10 parts of tetrazouron, 60 parts of pendimethalin and 20 parts of mesotrione. After the above-mentioned raw materials are mixed evenly in a double-helix conical mixer, they are pulverized by a jet mill and made into a powder shape.

Abstract

The invention provides application of wettable powder with fluoroglycofen; the wettable powder with fluoroglycofen is applied to weeding; an active ingredient in the wettable powder is a composition with fluoroglycofen; the composition with fluoroglycofen is prepared from, by weight, 20 parts of fluoroglycofen, 5-50 parts of flazasulfuron, 5-50 parts of tebuthiuron, 10-80 parts of pendimethalin, and 10-80 parts of mesotrione. Through extensive studies, the inventor discovers that the application of the wettable powder with fluoroglycofen in weeding provides significant effect, agent resistance in weeds can be decreased, usage is low, and less environmental burden on herbicide application sites or their surroundings than the prior art is caused.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to the application of a wettable powder containing acifluorfen. Background technique [0002] Cotton is the main economic crop in my country, and effective control of weeds in cotton fields is one of the important measures to improve cotton yield and quality. There are many kinds of weeds in cotton fields, which compete with crops for glory, fertilizer and water, and can also break through the mulch, which is an important factor causing crop yield loss. [0003] The herbicides used in cotton fields are mostly soil treatment herbicides, mainly pendimethalin, trifluralin and acetochlor. With the continuous application of pendimethalin and other herbicides for a long time, resistance to them Medicinal weeds are increasing year by year, and due to the selectivity of pendimethalin and other herbicides on weeds, the number of sensitive weeds has decreased, while insensitive weeds su...
