Application of Inducer in Controlling Strawberry Botrytis and Increasing Chlorophyll Content and Decreasing Cell Membrane Permeability

Abstract

The invention discloses an application of an inducer in preventing and treating gray mold of strawberry, increasing chlorophyll content, and reducing cell membrane permeability. % of phosphite. The present invention combines amino oligosaccharin and phosphite, and the ratio of the obtained inducer components is reasonable, and the control effect on strawberry anthracnose and gray mold disease is better, and at the same time, it can increase the thickness of strawberry rhizomes and reduce the permeability of cell membranes. Improve stress resistance, increase leaf chlorophyll content and other growth potential indicators, can reduce the use of chemical agents, reduce pesticide residues in strawberry fruits, food safety risks and ecological environment hazards.

Description

technical field [0001] The invention relates to the technical field of biopesticides, in particular to the application of inducers in preventing and treating strawberry gray mold, increasing chlorophyll content and reducing cell membrane permeability. Background technique [0002] Strawberry will be harmed by many kinds of pathogenic bacteria during the whole growth process, among which anthracnose and gray mold are the main diseases of strawberry seedling and cultivation stage, which become the bottleneck problem of strawberry industry development. [0003] Strawberry anthracnose is the most important disease in strawberry seedling cultivation and initial planting stage. The pathogen mainly damages the leaves, petioles, stolons and rhizomes during the seedling stage, and the leaves show dark brown spots. Lesions on petioles and stolons are spindle-shaped, initially reddish-brown, then black and sunken. When the lesion surrounds the petiole or stolon for a week, the part a...

AI Technical Summary

Problems solved by technology

[0009] Although the research and application of some cultivation techniques can reduce the occurrence of anthracnose and gray mold, the risks and costs are high, and there are no absolutely high-quality strawberry varieties with strong disease resistance

At present, the prevention and treatment of fungal diseases such as anthracnose and gray mold at home and abroad mainly rely on chemical agents. Although they can prevent and control some diseases to a certain extent, the long-term and large-scale use of pesticides has also increased pesticide residues in strawberry fruits and food safety risks and ecological conditions. environmental hazards

[0010] However, there are still few reports on the use of plant inducers to prevent and treat strawberry anthracnose and gray mold, and there are few reports on the inducers that prevent and control strawberry diseases while improving plant growth vigor.
