Abstract

The invention relates to a medicinal plant weeding composition, which is characterized in that clopyralid, picloram or aminopyralid and benazolin are used as main active components; and weight ratio of clopyralid to picloram or aminopyralid to benazolin is 1-50:1-50:1-50. The weeding composition is used for treatment of postemergence stem leaf in oilseed rape fields and / or medicinal plant fields, is applied in prevention and removal of field weeds, and has a remarkable synergistic effect.

Description

[0001] Technical areas: [0002] The invention belongs to the field of agricultural herbicides and relates to a medicinal plant herbicide composition. [0003] technical background: [0004] Picloram, also known as picloram, CAS registration number: 1918-02-1. The structural formula is as follows, [0005] [0006] Amclopyralid is a hormonal herbicide that can be absorbed by plant leaves, roots and stems, and can be quickly transmitted to the growing point, causing deformity, wilting, defoliation, necrosis of the upper part of the plant, blockage and discoloration of the xylem vessels, and ultimately the death of the plant. . The mechanism of action is to inhibit mitochondrial system respiration and nucleic acid metabolism. [0007] Clopyralid, chemical name: 3,6-dichloro-2-pyridinecarboxylic acid, CAS number: 1702-17-6, structural formula is as follows: [0008] [0009] Clopyralid is a synthetic plant growth hormone. Its chemical structure is similar to many natural...
