Embodiment 1

[0021] Example 1: 70% flusasulfuron-cyprosulfuron-methyl water-dispersible granules

[0022] Flucarbasulfuron-methyl 50%, Cyprosulfuron-methyl 20%, Sodium Lauryl Sulfate 5%, Alkylphenol Polyoxyethylene Ether Sulfate 5%, Sodium Bicarbonate 2%, Kaolin Clay 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. 70% flusasulfuron-cyprosulfuron water-dispersible granules can be prepared.

Embodiment 2

[0023] Example 2: 80% flusasulfuron-cyprosulfuron wettable powder

[0024] Flucarbasulfuron 50%, Cyprosulfuron 30%, Sodium Lauryl Sulfate 5%, Alkylphenol Polyoxyethylene Ether Formaldehyde Condensate 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-cyprosulfuron wettable powder.

Embodiment 3

[0025] Example 3: 30% flusasulfuron-cyprosulfuron oil suspension concentrate

[0026] Fluazosulfuron 12%, Cyprosulfuron 18%, Naphthalenesulfonate Formaldehyde Condensate 10%, Sodium Dodecyl Benzene Sulfonate 10%, Magnesium Aluminum Silicate 2%, Refined soybean oil makes up 100%. After the above-mentioned 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 30% fluazosulfuron-cypromell Sulfururon oil suspension.

Abstract

The invention discloses herbicide composition containing flucarbazone-sodium and fcyclosulfamuron. The herbicide composition comprises effective components, namely, the flucarbazone-sodium and the fcyclosulfamuron, wherein the weight part ratio of the flucarbazone-sodium to the fcyclosulfamuron is in a range of 10:1-1:10. The herbicide composition has a synergistic interaction effect on wheatland grass weeds and broadleaf weeds, compared with exclusive use of a single agent, the composition has the advantages that the weed eradication effect is obviously improved, the herbicide controlling spectrum is expanded, meanwhile, the pesticide usage amount is reduced, the environmental pollution is reduced, and production of thedrug resistance of weeds is delayed.

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 cyprosulfuron-methyl 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] Cyclosulfamuron (fcyclosulfamuron) is a sulfonamide herbicide, the ...
