How to treat branch diseases of peach trees

Peach trees are widely planted in China, and peaches are also loved by the people. they have good appearance, plump, juicy flesh and rich nutrition. But there are a lot of diseases when peach trees are planted. So, how to treat peach branch diseases?

First, how to treat peach branch diseases?

Peach branch diseases include gum disease and wood rot. Gummosis can be prevented by applying high concentrations of fungicides such as tebuconazole, carbendazim, methyl thiophanate, stone sulfur mixture, Bordeaux solution and so on. When wood rot occurs, the diseased tree should be trimmed, scraped, painted and protected by tebuconazole, and attention should be paid to the maintenance of the tree and the stability of the tree potential.

1. Glue disease

It can be divided into two categories: non-infectious rheumatosis and infectious rheumatosis.

Non-infectious gum disease: freezing injury, sunburn, water and other environmental stress, tree damage caused by some insect pests such as longicorn beetles, lack of calcium and boron can induce this kind of glue flow.

Infectious gummy disease: Staphylococcus aureus is the main pathogen of infectious rheumatosis, which usually exudes black, milky colloids in the wound.

As the peach gum disease is difficult to cure, prevention must be given priority to, and prevention must be combined. Specific measures include ridging cultivation, stabilizing tree potential, balanced nutrition, spraying sea elves biological stimulants during physiological period, reasonable load, reducing tree damage, etc., for the glue that has flowed, it can be coated with high concentrations of fungicides such as tebuconazole, carbendazim, methyl thiophanate, stone sulfur mixture, Bordeaux solution and so on.

2. Wood rot

It mainly harms the branches of peach trees, which will invade from the wound, destroy xylem fiber tissue, affect the transport of nutrients, and reduce the toughness of branches.

Old trees, weak trees with diseases and insect pests, and gardens with many wounds are seriously ill.

The diseased trees can be trimmed, scraped, painted and protected by tebuconazole, and attention should be paid to the maintenance and stability of the trees.
