Abstract

The invention relates to a rice weeding composition containing pyriminobac-methyl, mesotrione and bensulfuron-methyl. The active ingredients of the weeding composition are the following ternary effective ingredients: pyriminobac-methyl, mesotrione and bensulfuron-methyl, and the weight ratio of pyriminobac-methyl to mesotrione to bensulfuron-methyl is (2.6-2.8): (4.3-4.7): (4-5). The weeding composition has a synergistic effect, can be used for preventing and removing annual gramineous weeds, broadleaf weeds and nutgrass flatsedge in a paddy field by expanding a weed control spectrum, has a remarkable weeding effect, has no influence on succeeding crops, and is an ideal herbicide.

Description

[0001] This application is a divisional application, the parent application number is CN201710017202.0, and the name is "a rice herbicidal composition containing pyrifluzal, mesotrione and bensulfuron-methyl". technical field [0002] The invention relates to the technical field of pesticide herbicides, in particular to a rice herbicidal composition containing pyrifluzal, mesotrione and bensulfuron-methyl. Background technique [0003] Chemical weeding is one of the main means of controlling field weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance; at the same time, due to the complex grass phase and various types of weeds in the field, such as grass weeds, broad-leaved weeds and sedges Mixed occurrence of grass and the like, the use of a single species of herbicide has been unable to effectively solve the above problems, and all will show a certain aspect of defects. Through the screeni...
