Abstract

The invention discloses a mixed herbicide containing saflufenacil and chlortoluron. The herbicide takes the saflufenacil and the chlortoluron as main effective components, and the mass ratio of the saflufenacil to the chlortoluron is (0.1-80):(0.1-80). The mixed herbicide is applied to wheat paddock post-emergence weeding and has the advantages of broad spectrum, rapid acting, high efficiency, lowtoxicity, safety, environmental protection and the like.

Description

technical field [0001] This patent belongs to the technical field of pesticides, especially the field of herbicides, and relates to a binary compound of saflufenacil and chlorotoluron. The herbicide composition can be used for post-emergence weeding in wheat fields. Background technique [0002] Saflufenacil, molecular formula: C 17 h 17 CIF 4 N 4 o 5 S, chemical name: N'-[2-chloro-4-fluoro-5-(1,2,3,6-tetrahydro-3-methyl-2,6-dioxo-4-trifluoromethylpyrimidine -1-yl)benzoyl]-N-isopropyl-N-methylsulfonamide is a uracil herbicide developed by BASF and is a protoporphyrinogen oxidase (PPO) inhibitor, which is After inhibition, the cell membrane is destroyed, resulting in cell leakage, tissue necrosis, and eventually plant death. It can be used as a total herbicide, which can effectively control a variety of broad-leaved weeds, including weeds resistant to glyphosate, ALS and triazines, and can also be used to control broad-leaved weeds in wheat fields. [0003] Chlortolur...
