Abstract

The invention discloses a herbicidal compositions containing safety agent, which contains 3-methyl-2-[5-(2-chlor-4- trifluoromethylphenoxy)-2-nitrylbenzoxy]-3-ethyl crotonate(SYP-249) as effective constituent and a herbicidal safety agent selected from fenchlorazole, mefenpyr-diethyl, dichlormid, brassinolide. Herbicidal compositions is respectively processed to missible oil, suspending agent (emulsion), aqueous emulsion, microemulsion, water dispersed granule, wettable powder. Disposal of the wheat leaf and growth spot with the said composition can relieve the damage to wheat of herbicide without influencing the weeds prevention and expelling effect.

Description

technical field [0001] The present invention belongs to the field of herbicides. It relates to a herbicidal composition containing a safener. Background technique [0002] Chemical herbicides are easy to cause damage to the crops that people need while eliminating weeds. For the herbicidal composition, one of the most important requirements is its selectivity, that is, it only acts on the target, and does not affect the crops that do not affect. crops grow. [0003] 3-methyl-2-[5-(2-chloro-4-trifluoromethylphenoxy)-2-nitrobenzoyl]-3-butenoic acid ethyl ester (test code SYP-249) is A broad-spectrum herbicide has the characteristics of fast herbicidal speed and herbicidal activity for soil and stem and leaf treatment. The preparation and application of its compound have been disclosed in the Chinese invention patent application CN1325624A. Further studies have found that the herbicide has an excellent herbicidal effect on broad-leaved weeds, but it tends to cause greater da...
