Embodiment 1

[0021] Example 1: 70% Fluoxsulfuron·Oximetrione water dispersible granules.

[0022] Fluoxuron-methyl 60%, oximetrione 10%, sodium butylnaphthalene sulfonate 5%, lignosulfonate 8%, sodium bicarbonate 2%, diatomaceous earth supplement 100%. The above-mentioned active ingredients, dispersing agent, wetting agent, disintegrating agent and solid carrier are mixed uniformly, pulverized with a superfine jet mill, kneaded, and then added to a fluidized bed granulation dryer for granulation, drying, and screening, The 70% fluoxasulfone·oximetrione water dispersible granules can be prepared.

Embodiment 2

[0023] Example 2: 80% fluoxasulfone·oximetrione wettable powder.

[0024] Fluoxuron-methyl 15%, oximetrione 65%, sodium alkyl sulfonate 5%, polycarboxylate 5%, light calcium carbonate supplement 100%. Mixing the above-mentioned active ingredients, dispersant, wetting agent and solid carrier, mechanically pulverizing, then jet pulverizing, and mixing evenly, 80% fluoxasulfone·oximetrione wettable powder can be prepared.

Embodiment 3

[0025] Example 3: 30% fluoxasulfone·oximetrione aqueous suspension.

[0026] Fluoxuron-methyl 20%, Oximefon 10%, Alkylphenol Ethoxylate 10%, Propylene Glycol 2%, Xanthan Gum 1%, Silicone Oil 0.5%, Deionized Water Makes Up 100%. The above-mentioned active ingredients and additives are dispersed by high-speed shearing and sanded in a sand mill to form a highly dispersed and stable suspension system in an aqueous medium, and then a 30% suspension of fluoxasulfone·oximetrione in water can be obtained. agent.

Abstract

The invention relates to a weeding composition containing flucarbazone sodium and tralkoxydim. The flucarbazone sodium and the tralkoxydim are active components of the weeding composition, wherein the weight part ratio of the flucarbazone sodium to the tralkoxydim is (50:1)-(1:30), and the total weight percentage of the flucarbazone sodium and the tralkoxydim in the weeding composition is 5-85 percent. The flucarbazone sodium and the tralkoxydim are compounded to play a synergistic interaction role on wheat paddock gramineous weeds; the weeding effect is obviously improved in comparison with that of the weeding composition which only uses a single medicament; the weeding composition is safe to wheat; meanwhile, the use amount of a pesticide is reduced, the pollution caused by the pesticide to the environment is reduced, and the generation of drug resistance of the weeds is slowed down.

Description

technical field [0001] The invention relates to a pesticide herbicidal composition and the application field thereof, in particular to a herbicidal composition with fluoxasulfone and oximetrione as active ingredients, which is used for controlling grass weeds in wheat fields. Background technique [0002] Flucarbazone-sodium (flucarbazone-sodium) is a sulfonylurea type systemic high-efficiency wheat field herbicide, which has obvious control effect on grass weeds such as wild oat, brome, and buckwheat and some broad-leaved weeds. Its active ingredients can be absorbed by the roots, stems and leaves of weeds, and exert herbicidal activity by inhibiting the activity of acetolactate synthase in the weeds and destroying the normal physiological and biochemical metabolism of weeds. Has excellent security. [0003] Tralkoxydim belongs to the class of cyclohexenone herbicides and is an inhibitor of acetyl-CoA carboxylase. After foliar application, it is quickly absorbed and transf...
