Abstract

The invention discloses a herbicidal compound containing 2,4-D and clopyralid, which comprises raw medicines and an auxiliary material, wherein the raw medicines consist of the 2,4-D and the clopyralid. The invention further discloses a preparation method and an application of the herbicidal compound. According to the invention, the advantages and the defects of the mixture of the 2,4-D and the clopyralid are complementary, and besides, synergistic action is achieved. The obtained herbicidal compound can broaden weeding spectrum, improve weeding effect, lower consumption, save economic cost, greatly reduce the use quantity of the active ingredient of each medicine, and lower the residue of the medicine in the environment and residual activity, and has important bionomics and environment protection significance.

Description

technical field [0001] The invention relates to a herbicidal composition containing 2,4-D and clopyralid, a preparation method of the herbicidal composition and its application in preventing and controlling weeds in wheat fields and corn fields, belonging 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] 2,4-D (2,4-D), molecular formula: C 8 h 6 Cl 2 o 3 , chemical name: 2,4-dichlorophenoxyacetic acid. 2,4-D is a phenoxycarboxylic acid selective systemic conduction hormone herbicide, which has strong systemic conductance and can inhibit plant growth and development...
