Abstract

The invention discloses a flucarbazone-Na compounded herbicide which comprises an active component I (flucarbazone-Na), an active component II and auxiliary components, wherein the active component II is one or a combination of several of mesosulfuron methyl, isoproturon, chlortoluron, pyroxsulam, Clodinafop-propargyl, carfentrazone-ethyl, tribenuron-methyl, fluroxypyr, methoxone, 2,4-D-butyl ester, dicamba, bromoxynil, thifensulfuron methyl, amidosulfuron, bensulfuron-methyl, flumetsulam, fluoroglycofen-ethyl and florasulam; the auxiliary components comprise an auxiliary agent and also comprise one of a filler and a solvent; the auxiliary agent is one or a combination of two of an emulsifying agent, a dispersant, a wetting agent, a disintegrant, an agglomerant, an antifreezing agent and a thickening agent; the mass sum of the active component I (flucarbazone-Na) and the active component II is 1%-85% of the total mass of the flucarbazone-Na compounded herbicide; and the mass ratio of the active component I to the active component II is (1:20)-(20:1). The flucarbazone-Na compounded herbicide disclosed by the invention is a novel herbicide for preventing and removing weeds in a wheatland.

Description

technical field [0001] The invention relates to a herbicide, in particular to a compound herbicide containing flucarbasulfuron. 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 poor ...
