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 combination 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 combination of promasulfuron-methyl and etoxyfen has been found.

Abstract

The invention discloses a herbicidal composition containing rimsulfuron-methyl and ethoxyfen, the herbicidal composition uses rimsulfuron-methyl and ethoxyfen as main active ingredients, The mass ratio of promethazone-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 ethoxyfen, which can be used for 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] Ethoxyfen, chemical name: 2',3'-dichloro-N-(4-ethoxymethoxybenzoyl)anilide, structural formula: [0004] [0005] Ethoxyfen is an amide herbicide, which is mainly used for pre-emergence or post-emergence weeding in rice fields. [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 canno...
