Embodiment 1

[0021] Example 1: 75% flusasulfuron-monasulfuron-methyl water-dispersible granules.

[0022] Fluazosulfuron-methyl 40%, monosulfuron-methyl 35%, sodium butylnaphthalene sulfonate 5%, alkylphenol polyoxyethylene ether 5%, urea 2%, and kaolin 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-monazosulfuron water-dispersible granules can be prepared.

Embodiment 2

[0023] Example 2: 80% flusasulfuron-monasulfuron-methyl wettable powder.

[0024] Fluazosulfuron-methyl 20%, monosulfuron-methyl 60%, sodium dodecylbenzene sulfonate 5%, alkylphenol polyoxyethylene ether sulfate 5%, diatomaceous earth make up 100%. Mix the above-mentioned active ingredients, dispersant, wetting agent and solid carrier, mechanically pulverize, then airflow pulverize, and mix evenly to prepare 80% flusasulfuron-monosulfuron-methyl wettable powder.

Embodiment 3

[0025] Example 3: 25% flusasulfuron-monasulfuron-methyl oil suspension concentrate.

[0026] Flucarbasulfuron-methyl 10%, monosulfuron-methyl 15%, alkylphenol polyoxyethylene ether sulfate 10%, sodium alkylsulfonate 10%, hydroxymethyl cellulose 0.2%, 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 Long oil suspension.

Abstract

The invention relates to a weeding composition containing flucarbazone and monosulfuron. The effective components comprise flucarbazone and monosulfuron in a weight ratio of 10:1-1:10. 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 monosulfuron-methyl 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 systemic high-efficiency wheat field herbicide of sulfonylureas, which has obvious control effects on grass weeds such as wild oats, brome, and arinaea and some broad-leaved weeds. 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] Monosulfuron-methyl is a new type of sulfonylurea herbicide. The d...
