Weeding composition containing propyrisulfuron and diflufenican and application thereof

A herbicidal composition, the technology of trisulfuron-methyl, is applied in the fields of pesticides and herbicides, and can solve the problem that the herbicidal composition of trisulfuron-methyl and diflufenacil has not yet been found, and the weeds in paddy fields cannot be completely and effectively controlled. Residual poisoning of current crops or subsequent crops can reduce the rate of weed resistance, improve safety, and improve drug efficacy.

Problems solved by technology

[0006] At present, herbicides in paddy fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in paddy fields. Too long effective period, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops
The inventor found through research that the synergistic compounding of herbicides is an effective measure to expand the weed control spectrum and improve the control effect. So far, no herbicidal composition related to the compounding of promasulfuron-methyl and diflufenican has been found.

Abstract

The invention discloses a herbicidal composition containing promasulfuron-methyl and diflufenican. The mass ratio of sulfuron-methyl is 1:60-60:1. The invention also discloses the application of the herbicidal composition in post-emergence weeding in paddy fields, especially the application in controlling gramineous and broad-leaved weeds in paddy fields. The herbicidal composition of the present invention is used for post-emergence weeding in paddy fields, especially for controlling gramineous and broad-leaved weeds in paddy fields. It has a wide spectrum, a long duration of effect, and is safe for rice and subsequent crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and in particular relates to a binary compound herbicidal composition containing promasulfuron-methyl and diflufenican, which can be applied to post-emergence weeding in paddy fields. Background technique [0002] Propyrisulfuron is a selective broad-spectrum herbicide, which has a good control effect on weeds resistant to sulfonylurea herbicides, and is effective on older barnyardgrass, sedge, and broad-leaved grass. Can be foliar spray, shake application. [0003] Diflufenican, chemical name: 2',4'-difluoro-[2-(3-trifluoromethylphenoxy)]-3-pyridineanilide, structural formula: [0004] [0005] Diflufenican is an amide herbicide, applied before or after weed germination can form a leaching-resistant medicinal soil layer on the soil surface, and maintain activity throughout the growing season of the crop. When the weeds germinate through the medic...
