Abstract

The present invention provides a herbicide containing a coptis extract and application thereof in peanut planting in saline-alkali soil. The herbicide comprises the following raw material components: 0.5-3.5 parts of pendimethalin, 4.2-8.6 parts of a coptis extract, 3-4.6 parts of myrcene, 3.5-6.5 parts of lignosulfonate, 14-20 parts of an emulsifier and 24-40 parts of a solvent. The emulsifier is a fatty alcohol polyethyleneglycol ether. The solvent comprises water, ethanol and toluene, wherein the weight ratio of water to ethanol to toluene is 3:5:2. The application of the herbicide in peanut planting in saline-alkali soil comprises steps of: firstly, diluting the herbicide by 200-250 times; and then, spraying the diluted herbicide of 90 ml per hectacre. By using the herbicide provided by the invention, the control effects of petunia, bermudagrass, cyperus rotundus and sonchus oleraceus are 99.6-100%, 99.1-99.4%, 99.4-99.6% and 97.5-98.5%, respectively.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and relates to a herbicide containing Coptis chinensis extract, in particular to a herbicide containing Coptis chinensis extract and its application in peanut planting in saline-alkali land. Background technique [0002] Coptis chinensis, shaped like chicken feet, has a single rhizome of 3-6cm long and 0.3-0.8cm in diameter. The surface is gray-yellow or yellowish-brown, rough, with irregular nodular protrusions, fibrous roots and fibrous root residues, and some internodes have smooth surfaces like stems, which are commonly called "crossing bridges". Hard, irregular section, orange-red or dark brown skin, bright yellow or orange-yellow xylem, arranged radially, and hollow pith. Slight gas, extremely bitter taste. Coptis chinensis extract has strong disease resistance and is a plant resource with great potential for development. It is a natural product extracted from Coptis chinensis as a raw...
