Mixed herbicide with saflufenacil and isoproturon

Abstract

The invention discloses a mixed herbicide with saflufenacil and isoproturon. According to the mixed herbicide, the saflufenacil and the isoproturon serve as main effective components, and the mass ratio of the saflufenacil to the isoproturon is (1-80):(1-80). The mixed herbicide is applied to wheat-paddock post-seedling weeding, and has the advantages of being broad in spectrum, quick in effect taking, efficient, lowly toxic, safe, environmentally friendly and the like.

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 isoproturon. 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 crop fields...

AI Technical Summary

Problems solved by technology

For wheat, barley, cotton, corn, soybean, pea, broad bean, peanut and other crops to control annual gramineous weeds and broad-leaved weeds, such as alopecia, crabgrass, wild oats, quinoa, bluegrass and other weeds , the effect on flat storage, Lone grass, Motherwort, Artemisia annua, etc. is poor

[0004] At present, herbicides in wheat fields are limited by the safety of crops, and their herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in wheat fields. If the effective period is too short, the dosage is too large or the application is uneven, it will easily cause residual toxicity to the crops of the current season or the subsequent crops.
