Abstract

The invention relates to a herbicide composition containing nicosulfuron, atrazine and clopyralid, which optimally uses the nicosulfuron, the atrazine and the clopyralid as active ingredients, wherein the weight ratio of the atrazine to the nicosulfuron to affinity is 40-1:20-1:10-1. The herbicide composition has the advantages of low toxicity, weak allergenicity and few damages to human and livestock, broad herbicide controlling spectrum and remarkable weed control strengthening effect and is suitable for preventing and controlling various weeds in fields of various crops, particularly corn fields.

Description

Technical field [0001] The present invention belongs to the field of pesticides, and specifically relates to a herbicide composition. The invention provides a pesticide and herbicide composition compounded of triazepines, sulfonylureas and synthetic hormone herbicides. Background technique [0002] Competing with crops for glory, fertilizer, and water, farmland weeds cause great losses to crop production every year. The current method of preventing and controlling farmland weeds is mainly to spray herbicides. A single type of herbicide has a narrow herbicidal spectrum, and a multi-component compound The herbicide composition can expand the herbicidal spectrum. [0003] Triazepine herbicides (such as atrazine, prometryn) are systemic, conductive pre- and post-emergent herbicides that kill weeds by interfering with photosynthesis of plants; sulfonylurea herbicides (such as Nicosulfuron-methyl) are mostly post-emergence herbicides that can be absorbed and transmitted by plant...
