Abstract

The invention discloses a herbicidal compound containing 2,4-D and picloram, which comprises raw medicines and an auxiliary material, wherein the raw medicines include the 2,4-D and the picloram. The invention further comprises a preparation method and an application of the herbicidal compound. The herbicidal compound can be used for preventing and curing weeds in wheat field and corn field, has a wide weeding spectrum, remarkably improves drug effect, lowers use quantity, saves economic cost, greatly reduces the use quantity of each type of active material, particularly reduces the use quantity of the picloram so as to decrease the residual herbicidal compound in the environment, and has important bionomics and environment protection significance.

Description

technical field [0001] The invention relates to a herbicidal composition containing 2,4-D and picloram, 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] 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 at low concentrations, causing deformities and even death. It is mainly used for The post-em...
