Herbicide composition and use thereof

Abstract

The invention discloses an herbicide composition. The herbicide composition contains amicarbazone, mesotrione and foramsulfuron. With respect to one part by weight of amicarbazone, the mesotrione content is 0.01-90 parts by weight, and the foramsulfuron content is 0.005-45 parts by weight. The invention further provides application of the herbicide composition in crop field weed prevention and control. By adopting the technical scheme, the amicarbazone, the mesotrione and the foramsulfuron in the herbicide composition can play obvious synergistic effect, and accordingly the herbicide efficiency is improved.

Description

technical field [0001] The present invention relates to the field of agriculture, in particular to a herbicide composition and the use of the herbicide composition. Background technique [0002] Field weeds compete with crops for water and fertilizer, which is one of the main factors affecting crop yields. If they are not controlled, they will cause a large reduction in crop yield. The main weeds that harm crops are: crabgrass, barnyardgrass, foxtail, goosegrass, amaranth, purslane, amaranthus, quinoa, thistle, bindweed, commelina, etc. [0003] At present, the main herbicide varieties used to control field weeds are: amide herbicides, such as alachlor, acetochlor, etc. The efficacy of such herbicides is greatly affected by external climatic conditions, such as affected by soil moisture, When the moisture content is poor, the herbicidal effect is significantly reduced; triazine herbicides: such as atrazine, the safety of this type of herbicides on crops is greatly affected ...

AI Technical Summary

Problems solved by technology

[0003] At present, the main herbicide varieties used to control field weeds are: amide herbicides, such as alachlor, acetochlor, etc. The efficacy of such herbicides is greatly affected by external climatic conditions, such as affected by soil moisture, When the moisture content is poor, the herbicidal effect is significantly reduced; triazine herbicides: such as atrazine, the safety of this type of herbicides on crops is greatly affected by environmental conditions and crop growth periods, and improper application may cause serious damage. Phytotoxicity, and a large amount of long-term use is likely to cause soil compaction, groundwater pollution, ecological environment deterioration, the rise of drug-resistant weeds, and affect the safety of subsequent crops

Phenoxycarboxylic acid and benzoic acid herbicides: belong to hormone herbicides, such as 2,4-D butyl ester, paraquat, etc. These herbicides are usually used for stem and leaf treatment to control annual and perennial broad-leaved weeds , but the safety of crops is greatly affected by environmental conditions (especially temperature and humidity conditions) and the growth period of crops. Improper use can easily cause phytotoxicity. Acylimide herbicides: belong to the propurine oxidase inhibitors, such as flucarbamate, mainly used for the control of broad-leaved weeds, especially for cocklebur, quinoa, morning glory, purslane, etc.

[0004] Weeds become increasingly resistant to existing herbicides as the herbicide ages, resulting in lower herbicide efficacy
