Abstract

The invention relates to a herbicide composition, comprising clodinafop-propargyl and carfentrazone-ethyl and made into a pesticide formulation such as suspending agent, wettable powder, water-dispersion granule and the like. Preferably, the clodinafop-propargyl accounts for 0.5 to 20 %, the carfentrazone-ethyl accounts for 5 to 30 %.the herbicidal composition provided by the invention avoids the defect of single component, and has remarkable preventing effect excel in the single preparation. The herbicidal composition can prevent and remove a majority of monogenus and dicotyledonous weeds once only and has quick-effective, broadspectrum and longer-lasting-period characteristic.

Description

technical field [0001] The invention relates to a wheat field herbicide composition. Background technique [0002] At present, although there are many kinds of herbicides used in wheat fields, they can only control monocotyledonous or broad-leaved weeds, and the herbicide spectrum is narrow, and the safety is poor. It is difficult to control many resistant weeds. It has become more and more important to produce a pesticide that can control both monocotyledonous and broad-leaved weeds, and can control some resistant weeds. [0003] Clodinafop-propargyl is a systemic herbicide and belongs to adenosine deaminase inhibitors. CAS number: 105512-06-9, chemical name: (R)-2-[4-(5-chloro-3-fluoro-2-pyridyloxy)phenoxy] propargyl propanoate, the structural formula is as follows: [0004] Molecular formula: C 17 h 13 ClFNO 4 Molecular weight: 349.75 [0005] Oxoporprogyl is an excellent variety of herbicides, with high efficiency, low toxicity, and low residue. It can effectivel...
