Abstract

The invention discloses a herbicidal composition containing MCPA (2-methyl-4-chloro-phenoxyacetic acid) and clopyralid. The herbicidal composition comprises active pharmaceutical ingredients and auxiliary materials, and the active pharmaceutical ingredients comprise the 2-methyl-4-chloro-phenoxyacetic acid and the clopyralid. The invention further discloses a preparation method and application of the herbicidal composition. Compared with the prior art, the herbicidal composition disclosed by the invention has the following beneficial effects that: the herbicidal spectrum can be expanded by mixing the active ingredients of the herbicide, the herbicidal effect is improved, the period which is suitable for applying the herbicide is prolonged, the harm of the herbicide is reduced, the residual activity of the herbicide is reduced, the generation and development of resistance to the herbicide are deferred, and the herbicidal composition further has important ecological significance and environmental protection significance.

Description

technical field [0001] The invention relates to a herbicidal composition containing MCPA and clopyralid, a preparation method and application thereof, and belongs to the technical field of pesticides. Background technique [0002] With the further development of herbicide production and application, the mixed use of herbicides has gradually developed. my country also pays more attention to the research on the mixed use of herbicides, which is widely regarded as one of the important measures for the rational use of herbicides. A series of herbicide mixtures have been developed and great progress has been made. [0003] MCPA, molecular formula: C 9 h 9 ClO 3 , chemical name: 2-methyl-4 chlorophenoxyacetic acid. MCPA is a hormone-type selective herbicide, which is easily absorbed and conducted by roots and leaves, destroying the metabolism of plants, resulting in plant deformation, swelling, cracking, mildew and death. It is suitable for the control of rice, wheat and other...
