Herbicidal composition containing metamifop and Chipton

Abstract

The invention discloses a herbicidal composition containing metamifop and Chipton. The herbicidal composition contains active ingredients metamifop and a Chipton derivative at a weight ratio of 10-1:1-30. It is shown by drug effect experiments that the herbicidal composition possesses excellent complementarity and synergistic effect, is wide in weed control spectrum, is low in application amount, is long in appropriate period for spraying, is high in safety for crops, and is high in environmental compatibility; and environment pollution is reduced.

Description

technical field [0001] The present invention belongs to the field of agricultural plant protection, and in particular relates to a herbicidal composition with improved properties. Background technique [0002] The active ingredient, metamifop, is an aryloxyphenoxypropionate herbicide developed by Korea Chemical Technology Research Institute, which can control most annual grass weeds very well, and is different from most such herbicides. The difference is that fenpyramid is safe for rice and can effectively control the main weeds in paddy fields, such as barnyardgrass, daughter, crabgrass and goosegrass, and is mainly used for weeding in transplanted and direct-seeded paddy fields. Mefenpyramid has low toxicity, is environmentally safe, has wide compatibility, and is expected to be used for weeding other crops and lawns. It is a promising herbicide.

AI Technical Summary

Problems solved by technology

[0003] The active ingredient Chipton and its derivatives are phenoxycarboxylic acid selective herbicides with strong systemic conductivity. They are mainly used for post-emergence stem and leaf treatment, and the agents pass through the cuticle and cytoplasm Membrane, finally conducts to each part, produces different effects on nucleic acid and protein synthesis in different parts, inhibits nucleic acid metabolism and protein synthesis at the top of the plant, stops the growth of growth points, and cannot stretch young leaves until photosynthesis cannot proceed normally ; The agent transmitted to the lower part of the plant increases the synthesis of nucleic acid and protein in the stem tissue of the plant, promotes abnormal cell division, enlarges the root tip, loses the ability to absorb nutrients, causes the stem to be twisted and deformed, the sieve tube is blocked, and the phloem is damaged. The transportation of organic matter is hindered, which destroys the normal viability of the plant and eventually leads to the death of the plant
