Problems solved by technology

[0005] Dimethyl tetrachloride, 2,4-D butyl ester, dicamba, bromoxynil, rimsulfuron-methyl, bensulfuron-methyl, sulfazone, carboxyfluorfen, and florasulam can control wheat fields Most broadleaf weeds, but ineffective against grasses
[0006] Each of the above herbicides has its own unique herbicide spectrum and weeds that cannot be controlled, and the weed control effect is not very ideal when used alone

Abstract

The invention discloses a mesosulfuron-methyl compound herbicide which consists of mesosulfuron-methyl as active ingredient I, active ingredient II and auxiliary ingredients; the active ingredient II is the combination of one or more of flucarbazone-Na, isoproturon, chlortoluron, pyroxsulam, 2-methyl-4-chlorophenoxy acetic acid, 2,4-D butyl ester, dicamba, bromoxynil, amidosulfuron, bensulfuron-methyl, flumetsulam, fluoroglycofen-ethyl and florasulam; the auxiliary ingredients consists of adjuvant and one of filler and solvent, and the adjuvant is the combination of one or more of emulsifying agent, dispersing agent, wetting agent, disintegrant, binding agent, antifreezing agent and thickening agent; the sum of the weight of the mesosulfuron-methyl as the active ingredient I and the weight of the active ingredient II is 1 to 85 percent of the total weight of the mesosulfuron-methyl compound herbicide; and the weight ratio of the active ingredient I to the active ingredient II is 1:20 to 20:1. The mesosulfuron-methyl mixed herbicide is novel herbicide for wheatlands.

Description

technical field [0001] The invention relates to a herbicide, in particular to a compound herbicide containing methylsulfuron-methyl. Background technique [0002] Wheat is the most important food crop in northern my country. It is related to the national economy, the people's livelihood and the country's food security. It is mainly winter wheat, accounting for about 90%, and the weeds in the wheat field affect the growth of wheat. There are about 30 kinds of main weeds in wheat, such as kanmai, japanese kanmai, brome, bluegrass, hardgrass, clubhead grass, miscanthus, pigsweed, cow chickweed, mother-in-law, broken rice, sorrel Polygonum fragrans, Bugweed, Dacha, Wild Rapeseed, Artemisia sorenzo, Dacha, Maijiagong, Shepherd's Purse, Zeqi, Field bindweed, Prickly cabbage, Rice Crockpot, Chenopodium, Small Chenopodium, Plaque And Baogai grass, the currently commonly used herbicides for stems and leaves in wheat fields are only effective in controlling broad-leaved grasses, but ...
