Abstract

The invention relates to a herbicide composition containing mesotrione and nicosulfuron, which uses the mesotrione and the nicosulfuron as active ingredients, wherein the weight ratio of the mesotrione to the nicosulfuron is between 1:15 and 15:1. The invention has the advantages of low toxicity, weak allergenicity, 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 pesticide herbicides, in particular to a herbicide composition containing mesotrione and nicosulfuron. 【Background technique】 [0002] The crop yield is reduced due to the damage of weeds, so it is necessary to apply a large amount of herbicides to control weeds every year to recover the loss. In recent years, the harm of weeds on corn and other crops has become increasingly serious, and due to the excessive use of herbicides, weeds have become more and more resistant to pesticides, resulting in a decrease in the weed control effect year by year. Therefore, there is a need for herbicide varieties with better herbicidal efficacy. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide a herbicidal composition containing mesotrione and nicosulfuron as active components, which has a wider herbicidal spectrum and more excellent synergistic control effect. [0004]...
