Embodiment 1

[0021] Example 1: 75% flusasulfuron monosulfuronate water dispersible granules

[0022] Flucarbasulfuron 50%, monosulfuronate 25%, sodium dodecylbenzenesulfonate 5%, fatty acid ester sulfate 5%, sodium bicarbonate 2%, and bentonite make up 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. 75% flusasulfuron-monosulfuron water-dispersible granules can be prepared.

Embodiment 2

[0023] Example 2: 80% flusasulfuron monosulfuron wettable powder

[0024] Flucarbasulfuron 70%, monosulfuron 10%, sodium dodecylbenzene sulfonate 3%, tea dry powder 2%, naphthalene sulfonate formaldehyde condensate 5%, and diatomaceous earth 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% flusasulfuron-monosulfuron wettable powder can be prepared.

Embodiment 3

[0025] Example 3: 25% flusasulfuron monosulfuron monosulfurate oil suspension concentrate

[0026] Flucarbasulfuron 15%, monosulfuronate 10%, lignosulfonate 10%, sodium lauryl sulfate 10%, polyvinyl alcohol 0.1%, methyl oleate make up 100%. After the above active ingredients and additives are dispersed by high-speed shearing and sand-milled in a sand mill, a highly dispersed and stable suspension system is formed in a non-aqueous medium to prepare 25% fluazosulfuron monosulfuron Ester Oil Suspension Concentrate.

Abstract

The invention relates to a weeding composition containing flucarbazone and monosulfuron-ester. The effective components comprise flucarbazone and monosulfuron-ester in a weight ratio of 15:1-1:10. The weeding composition has synergic actions on grassy weeds and broadleaf weeds in wheat fields, has obviously better weeding effects than weedicides having single purpose and used individually, has wider weed control spectrum, lowers the pesticide consumption, reduces the environmental pollution and postpones the generation of drug resistance of weeds.

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 monosulfuronate as active ingredients, which is applied to grass weeds and broad-leaved weeds in wheat fields Prevention and treatment. Background technique [0002] Flucarbasulfuron-methyl is a sulfonylurea systemic high-efficiency wheat field herbicide. It has obvious control effects on grassy weeds such as wild oats, brome, and apricots and some broad-leaved weeds. Absorbed by the roots, stems and leaves of grass, it exerts herbicidal activity by inhibiting the activity of acetolactate synthase in weeds, destroying the normal physiological and biochemical metabolism of weeds, and can be quickly metabolized in wheat, which has excellent safety for wheat . [0003] Monosulfuronate is a new type of sulfonylurea super-efficient herbicide. Its mechanism of action is to prevent the synthesi...
