AI Technical Summary

Technical Problem

Existing chemical methods for controlling blueberry twig blight have problems such as the development of pathogen resistance, inhibition of root vitality, and inability to block systemic infection of mycelia within the vascular bundles.

Method used

The formula, which uses components such as deacetylated chitin, phenylalanine, abscisic acid, methyl jasmonate, and salicylic acid, activates plant immune responses and signaling pathways, promotes the synthesis of defense enzyme cascade reactions, synthesizes lignin and anthocyanins, and enhances the mechanical barrier and antioxidant capacity of the cell wall.

Benefits of technology

It effectively prevents blueberry twig blight infection, inhibits pathogen growth and spore germination, improves fruit quality and antioxidant capacity, and rapidly establishes a barrier to inhibit pathogen spread during infection.

Abstract

The application relates to the field of blueberry disease-resistant agents, in particular to a blueberry anti-withering disease promoter and a preparation method and application thereof. The agent comprises the following components in parts by weight: 2 parts of deacetyl chitin, 0.8-1.2 parts of phenylalanine, 0.4-0.6 parts of abscisic acid, 0.1-0.2 parts of methyl jasmonate, 0.2-0.4 parts of salicylic acid and 0.15-0.4 parts of sodium dodecyl benzene sulfonate. The application stimulates the blueberry plant to activate a defense enzyme cascade through deacetyl chitin, prevents infection in advance, and promotes the expression of defense genes through the cooperation of water and salt acid and methyl jasmonate when infection occurs; phenylalanine can synthesize lignin to prevent the spread of bacteria when infection occurs; and the fruit quality and anti-infection performance are improved through the cooperation of abscisic acid when no infection occurs; the application promotes the self-regulation of blueberries through the substances in the formula, improves the fruit quality when no infection occurs, and can quickly establish a barrier to inhibit the growth and reproduction of bacteria when infection occurs.
