The invention discloses an herbicide composition containing isoproturon, pretilachlor and diflufenican and a use thereof.
Active components of the herbicide composition comprise isoproturon, pretilachlor and diflufenican. A
mass ratio of isoproturon, pretilachlor to diflufenican is 10-50: 10-50: 1-20. The herbicide composition has obvious synergism in the above ratio range, reduces an herbicide use amount, reduces herbicide use frequency, reduces an herbicide use cost, reduces the unfavorable influence produced by the herbicide on an
ecological environment and enlarges a weeding spectrum. Through one herbicide use step, various
weed problems are solved and defects and limitation of single-ingredient herbicide use are overcome. The herbicide composition prolongs a service life and has an important meaning for comprehensive control of
weed resistance. The herbicide composition can fast produce effects for a long time, has a low use cost and can be used for preventing and controlling gramineous weeds, broadleaf weeds and
cyperaceae weeds in a
paddy field and gramineous weeds and broadleaf weeds in a wheat or barley field.
