Problems solved by technology

At present, many varieties of herbicides have been developed for these crops, but due to their single herbicidal spectrum, or long-term single use of similar herbicides, the succession of weed community distribution and weed resistance are increasing.

Abstract

The invention relates to a weeding composition which comprises fluroxypyr, bentazone and acceptable auxiliary components in pesticides, wherein the fluroxypyr and the bentazone are used as active components, and the weight percent of the fluroxypyr to the bentazone is 4:1-1:48. By combining the two active components, the weeding composition can have synergy, can prevent and remove various kinds of broad leaved weeds and sedge weeds, obviously improves the weeding effect, and reduces the production cost.

Description

Technical field [0001] The invention relates to a herbicide composition, especially a herbicide composition that can be used in paddy fields, wheat fields, corn fields, sugarcane fields, orchards and non-arable land. Background technique [0002] In rice fields, wheat fields, corn fields and other cultivation processes, the wide application of herbicides has played an important role in effectively controlling weed damage, expanding cultivation area, increasing yield, improving product quality, saving labor, and regulating labor. At present, many herbicides for these crops have been developed. However, due to their single herbicidal spectrum or long-term single use of similar herbicides of the same kind, the succession of weed community distribution and weed resistance have increased. [0003] Fluroxypyr is a pyridyloxyacetic acid herbicide with a structure shown in formula (I). It is a selective, systemic, post-emergence stem and leaf treatment agent, which is absorbed by weed stem...
