Abstract

The invention relates to an herbicide composition for a wheatland, and particularly relates to an herbicide composition for a wheatland, which contains two active ingredients, namely fenoxaprop-p-ethyl and halosulfuron-methyl, wherein the weight ratio of the fenoxaprop-p-ethyl to the halosulfuron-methyl is (1:8) to (32:1), and the active ingredients account for 10-80% of the compound herbicide by weight percentage. According to the herbicide composition, after the two active ingredients, namely the fenoxaprop-p-ethyl and the halosulfuron-methyl, are compounded, the preventing effect on weeds is improved by utilizing the complementarity of the two active ingredients, the shortcoming caused by that when two kinds of herbicides are independently used is overcome, and both grassy weeds and broadleaf weeds in the wheatland can be prevented and removed, so that an obvious synergy effect is achieved. The herbicide composition has an obvious herbicide effect, is safe to wheat, and has no influence on afterreap crops, so that the herbicide composition is an ideal herbicide.

Description

【Technical field】 [0001] The invention relates to an agricultural chemical composition, specifically a herbicide composition for controlling weeds in wheat fields compounded by fenoxaprop-ethyl and chlorpyrazosulfuron-methyl. 【Background technique】 [0002] Wheat is a gramineous plant widely planted all over the world. It is rich in starch, protein, fat, minerals, calcium, iron and vitamin A. It is the second largest food crop in the world and an important food crop in my country. one. However, in the growth process of wheat, there are many factors that affect the yield, among which the damage of weeds is an important aspect. Weeds in wheat fields can be simply divided into broad-leaved weeds and grass weeds according to their shape, among which broad-leaved weeds Mainly include wormwood, shepherd's purse, pig's weed, quinoa, spinach, commelina, dawanhua, etc. Grass family weeds mainly include wild oats, kaleidoscope, hard grass, brome, and barley. The main harm of weeds is...
