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 invention belongs to the field of pesticides, in particular to a herbicide composition. The invention provides a pesticide herbicide composition compounded by s-triazines, sulfonylureas and synthetic hormone herbicides. Background technique [0002] Due to competing with crops for glory, fertilizer, and water, farmland weeds cause great losses to crop production every year. At present, the main method of preventing and controlling farmland weeds is to spray herbicides. A single type of herbicide has a narrow herbicidal spectrum, while a multi-component compound The herbicide combination can expand the herbicidal spectrum. [0003] S-triazine herbicides (such as atrazine and promethazine) are systemic and conductive pre- and post-emergence herbicides, which kill weeds by interfering with plant photosynthesis; sulfonylurea herbicides (such as Nicosulfuron) are mostly post-emergence herbicides, which can be absorbed and conducted by plant stems and ...
