Abstract

The present invention discloses wheat field herbicide composition with synergistic effect. The wheat field herbicide composition is a ternary composition comprising fenoxaprop-P-ethyl, tribenuion-methyl, fluoroglycoen-ethyl and filling; or a binary composition comprising fenoxaprop-P-ethyl, tribenuion-methyl or fluoroglycoen-ethyl, and filling. It may be prepared into oil suspension, wettable powder, water dispersed pellet, oil emulsion, water emulsion, dry suspension or tablet. It is used mainly for wheat field with seedlings to preventing and killing gramineous weeds and broad-leaved weeds and has acting time covering the whole wheat growth period.

Description

technical field [0001] The invention belongs to chemical pesticides, in particular to a wheat field herbicide composition. Background technique [0002] As we all know, the long-term use of broad-leaved herbicides such as Trisulfuron-methyl, Dimethyltetrachlor, and Stetaron in wheat fields has gradually changed the weed community in wheat fields, and the occurrence of grass weeds has increased year by year, especially in the Jianghuai River Basin and the Yellow River Basin Grass weeds in the area have risen rapidly, and hard grass, bluegrass, wild oats, and apricot have developed into malignant weeds. Rapid control of vicious gramineous weeds has become an important subject of chemical weeding in wheat fields today. Fenoxaprop-ethyl can effectively control gramineous weeds such as hard grass, bluegrass, wild oats, chrysanthemum, foxtail; , Maijiagong, Iongrass, Swampy, Broken Michelia, Bugwort, Polygonum convolutum, etc., but tribenuron-methyl takes a long time to exert it...
