Embodiment 1

[0023] Example 1: 70% flusasulfuron-saflufenacil water-dispersible granules.

[0024] Flucarbasulfuron 50%, saflufenacil 20%, sodium dodecylbenzene sulfonate 5%, alkylphenol polyoxyethylene ether sulfate 5%, magnesium chloride 2%, white carbon black 10%, kaolin supplement 100%. Mix the above-mentioned active ingredients, dispersant, wetting agent, disintegrant and solid carrier evenly, pulverize with an ultrafine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation, drying, and sieving. 70% flusasulfuron-saflufenacil water dispersible granules can be prepared.

Embodiment 2

[0025] Example 2: 80% flusasulfuron-saflufenacil wettable powder.

[0026] Flucarbasulfuron 50%, saflufenacil 30%, sodium butylnaphthalene sulfonate 5%, alkylphenol polyoxyethylene ether sulfate 5%, and kaolin make up 100%. Mix the above-mentioned active ingredients, dispersant, wetting agent and solid carrier, mechanically pulverize, then airflow pulverize, mix evenly, and then 80% flucarbasulfuron-saflufenacil wettable powder can be prepared.

Embodiment 3

[0027] Example 3: 35% flusasulfuron-saflufenacil aqueous suspension concentrate.

[0028] Flucarbazone-methyl 20%, saflufenacil 15%, alkylphenol polyoxyethylene ether sulfate 5%, polycarboxylate 5%, polyethylene 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 sand-milled in a sand mill to form a highly dispersed and stable suspension system in an aqueous medium to prepare 35% flusasulfuron-saflufenacil water suspension.

Abstract

The invention relates to a weeding composition containing flucarbazone sodium and saflufenacil. The flucarbazone sodium and the saflufenacil are active components of the weeding composition, wherein the weight part ratio of the flucarbazone sodium to the saflufenacil is (20:1)-(1:20), and the total weight percentage of the flucarbazone sodium and the saflufenacil in the weeding composition is 0.1-85 percent. The flucarbazone sodium and the saflufenacil 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 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 present invention relates to a pesticide herbicidal composition and its application field, in particular to a herbicidal composition with fluasulfuron-methyl and saflufenacil as active ingredients, which is applied to gramineous weeds and broad-leaved weeds in wheat fields prevention and treatment. Background technique [0002] Flucarbazone-sodium is a sulfonylurea systemic high-efficiency wheat field herbicide, which has obvious control effects on grass weeds and some broad-leaved weeds such as wild oats, brome, and alopecia. Its active ingredients can be absorbed by the roots, stems and leaves of weeds. By inhibiting the activity of acetolactate synthase in weeds and destroying the normal physiological and biochemical metabolism of weeds, it exerts herbicidal activity. It can be quickly metabolized in wheat and has a good effect on wheat Has excellent security. [0003] Saflufenacil belongs to the pyroxindione herbicides and is an inhibitor of ...
