Problems solved by technology

However, different treatments have a great influence on the allelopathic effect of Pseudomonas sinensis. Many studies have found that the allelopathic effect of allelochemicals on recipient plants is multifaceted, which can affect cell turgor and leaf water potential, and can affect plant photosynthesis. And related processes, can affect a variety of plant metabolism and enzyme activity, can affect cell division and proliferation, can affect the integrity and permeability of cell and organelle membranes, can affect root growth and the absorption of mineral elements, etc.

Abstract

The invention discloses a eupatorium catarium extract and an application thereof and belongs to the technical field of comprehensive development and utilization of weeds. The eupatorium catarium extract is prepared through steps of water boiling and filtration or is prepared through a reflux extraction process with a 70% ethanol water solution. The eupatorium catarium extract is simple in preparation method and can be used as an active pesticide component for prevention and treatment of field weeds and diseases and insect pests. The eupatorium catarium extract has high activity, is harmless to human body, can turn harmful weeds into economic crops, and can help people to remove non-field eupatorium catarium positively, thereby protecting environment.

Description

technical field [0001] The invention belongs to the technical field of comprehensive development and utilization of weeds, and in particular relates to an extract of stinkweed and its application. Background technique [0002] Pseudomonas is one of the important invasive weeds in southern my country. It has caused harm to agriculture, forestry, animal husbandry and biodiversity, and has a tendency to spread northward. The false stinky grass is native to South America, mainly distributed in Argentina, Brazil and some other countries in South America, and is now distributed in the tropical regions of the Eastern Hemisphere. False stinkgrass likes a humid and sunny environment. It is extremely invasive and often forms dense bushes with a height of 0.3-1.0m, repelling other low herbaceous plants. Its population grows rapidly and has strong fertility. It is compatible with fruit trees and crops Competing for fertilizer and water will greatly damage the soil and seriously affect ...
