Abstract

The invention relates to a weeding composition containing profoxydim and application. According to the weeding composition, the active ingredient A is profoxydim, the active ingredient B is selected from any one of mefenacet, pyribenzoxim and bispyribac-sodium, the weight part ratio of the two active ingredients is 1: 50-50: 1, and the weeding composition is used for weeding in paddy fields, especially used for preventing and killing gramineae and broadleaf weeds and cyperaceae in the paddy fields. On the premise of improving the pesticide effect, compared with a single agent, the weeding composition delays the weed resistance, is wide in weeding spectrum and long in lasting period, and is safe to rice and afterreap crops.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a herbicidal composition containing cyclazone and its application. Background technique [0002] Rice has strong adaptability and is widely cultivated. It is one of the main food crops in the world and the largest food crop in my country. According to the national weed census data, there are more than 200 kinds of weeds in rice fields in my country, of which more than 20 kinds are more harmful. Rice field weeds are divided into three categories: one is grass weeds, the other is broad-leaved weeds, and the third is sedges. [0003] In recent years, due to the long-term single use of similar herbicides by growers, the resistance of weeds in rice fields has become stronger and stronger, resulting in worsening control effects of conventional herbicides, seriously affecting the high yield and harvest of rice. According to reports from many places across the country, barnyardgra...
