Problems solved by technology

However, clodinafop-propargyl is ineffective against broad-leaved weeds, and its herbicidal spectrum is relatively narrow, which limits its use
[0004] At present, herbicides in wheat fields are limited by the safety of crops, and the herbicide spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in wheat fields

Abstract

The invention discloses a mixture herbicide containing saflufenacil and clodinafop. The mixture herbicide is prepared from saflufenacil and clodinafop which serve as main active ingredients at a mass ratio of (1-80) to (1-80). The mixture herbicide containing saflufenacil and clodinafop has the advantages of wide spectrum, rapidness in effect taking, high efficiency, low toxicity, safety, environmental friendliness and the like when applied to post-emergence weeding of wheat fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and relates to a binary compound of saflufenacil and clodinafop-propargyl. The herbicide composition can be used for post-emergence weeding in wheat fields. Background technique [0002] Saflufenacil, chemical name: N'-[2-chloro-4-fluoro-5-(3-methyl-2,6-dioxo-4-(trifluoromethyl)-3, 6-Dihydro-1(2H)-pyrimidine)benzoyl]-N-isopropyl-N-methylsulfamide. Saflufenacil is a uracil herbicide developed by BASF and is a protoporphyrinogen oxidase (PPO) inhibitor. It can be used as a total herbicide and can effectively control a variety of broad-leaved weeds, including weeds resistant to glyphosate, ALS and triazines. It has a fast killing effect and the soil residues degrade rapidly. It can be used to control broad-leaved weeds in wheat fields or mixed with gramineous weed herbicides, such as glyphosate, which has a good effect. It can be applied in various cr...
