Problems solved by technology

[0008] 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

Abstract

The invention discloses a herbicide composition containing dicamba and imazosulfuron, and applications thereof. Dicamba and imazosulfuron are taken as active ingredients of the herbicide composition, and mass ratio of dicamba to imazosulfuron is 1-60:1-60. The herbicide composition can be used for weeding of paddy fields after seedling, and especially possesses excellent effects on preventing and killing grassy weed and broadleaf weed in paddy fields. Compared with single ingredient preparations, drug effect of the herbicide composition is improved, generation of weed resistance is delayed, weed control spectrum is broad, effect lasting period is long, and the herbicide composition is safe for both rice and afterreap crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, especially the field of herbicides, and specifically relates to a binary compound herbicidal composition of dicamba and fenpyrazosulfuron-methyl, which can be applied to post-emergence weeding in paddy fields. Background technique [0002] Dicamba, also known as dicamba; Baicao enemy. Chemical name: 3,6-dichloro-2-methoxybenzoic acid, structural formula: [0003] [0004] Dicamba is a hormonal herbicide. It has a systemic conduction effect and has a significant control effect on annual and perennial broad-leaved weeds. Dicamba is used for post-emergence spraying, and the drug can be quickly absorbed by the leaves, stems, and roots of the weed, conduct upward and downward through the phloem and xylem, and mostly concentrate in the meristematic tissue and parts with strong metabolic activities, hindering the normal activity of plant hormones , causing it to die. Generally, broad-leaved we...
