A kind of biopesticide composition and application of preventing and treating peach tree gummosis

Abstract

The invention discloses a biological pesticide composition for preventing and controlling the gummosis disease of peach trees, and an application thereof. Corresponding biological pesticides are respectively designed in a planted land soil treatment stage, a trunk wound treatment stage and a dormancy stage according to the pathogen characteristics and occurrence regularity of the gummosis disease of peach trees, prevention and control of the gummosis disease of peach trees are specially and systemically provided to fundamentally realize improvement of physical and chemical properties of soil and improvement of the fertility of the soil, wounds of invasion of pathogens to fountainhead trunks are medically protected and treated, and gummosis medicine treatment in the dormancy stage is assisted to comprehensively the gummosis disease of peach trees in an omnibearing manner, so the disease incidence is effectively reduced, branch withering and the mortality of peach trees are greatly reduced, disease loss is reduced, and the survival rate of the trees and the quality of fruits are improved; and additionally, the biological pesticide has the advantages of high safety, good environment compatibility and wide development prospect.

Description

technical field

[0001] The invention relates to the field of tree pest control, in particular to a biological pesticide composition and application for preventing and treating peach tree gummy disease. Background technique

[0002] Peach tree is a kind of commonly planted fruit tree, many fruit farmers plant large area of ​​peach tree to make a living.

[0003] The gum disease of peach trees mainly damages the trunk and main branches. After the branches are damaged, the diseased part swells slightly at the initial stage of the disease, and then secretes light yellow and transparent soft gum. The gum can also flow directly from the wound. After the gum comes into contact with the air, Gradually turn into reddish-brown, crystal clear, soft glue blocks, and finally become dark brown hard glue blocks, and the cortex of the diseased part gradually turns brown and rotten, and easily induces the infection of saprophytic fungi. It becomes weak day by day, the leaves turn yellow, wh...
