Abstract

The invention discloses a composition containing MCPA-Na and a cyclohexenone herbicide. The composition contains the effective ingredients of MCPA-Na and the cyclohexenone herbicide, wherein the mass ratio of MCPA-Na to the cyclohexenone herbicide is (1-10): (10:1); the preferential mass ratio of MCPA-Na to the cyclohexenone herbicide is (1-6): (6:1); the most preferential mass ratio of MCPA-Na to the cyclohexenone herbicide is (1-6): 1. The composition can adopt any one preparation formulation accepted by pesticides, and has a very good synergistic effect within a certain proportion range; compared with that of a single herbicide, the weeding effect of the composition is remarkably improved; meanwhile, the herbicide consumption and the cost are reduced, herbicide residues are reduced, and the potential threats of the pesticides to the environment are relieved.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a composition containing sodium 2-methyl-4-chloride and cyclohexenone herbicides and its use. Background technique [0002] Single use of a certain herbicide has been difficult to control the harm of a variety of mixed weeds. Therefore, the combination of herbicides, that is, mixing / mixing, has attracted more and more attention. Herbicide combination is an important means in the chemical control of weeds in farmland, and is widely used in crop fields such as rice, wheat, corn, cotton, soybean, and rapeseed. However, due to the selectivity and safety of herbicides, herbicide compositions are less used in hemp crop fields. The combination of three herbicides + clethodim has the control effect on weeds in flax field, which shows that the combination of herbicides can effectively control many kinds of weeds in flax field, such as A. It expands the herbicidal spectrum, improves ...
