How to Treat Peach Tree Branch and Trunk Diseases? A Detailed Guide to Prevention and Control Methods
Peach trees are planted across an extremely wide area in our country, and peaches are also a fruit deeply loved by the general public, with good appearance, plump and juicy flesh, and rich nutrition. However, peach trees encounter many diseases during cultivation. So, how do you treat peach tree branch and trunk diseases?
1. How to treat peach tree branch and trunk diseases?
Peach tree branch and trunk diseases include gummosis and wood rot. Gummosis can be prevented and controlled by brushing on high-concentration fungicides such as tebuconazole, carbendazim, thiophanate-methyl, lime sulfur mixture, and Bordeaux mixture. When wood rot occurs, the diseased tree body needs to be pruned, the trunk scraped, and paint + tebuconazole applied for protection, while also paying attention to tree care and maintaining tree vigor.
1. Gummosis
It can be divided into two types: non-infectious gummosis and infectious gummosis.
Non-infectious gummosis: environmental stresses such as freeze damage, sunscald, and moisture, tree damage caused by some pests such as longhorn beetles, and deficiencies of calcium and boron can all induce this type of gummosis.
Infectious gummosis: Botryosphaeria dothidea is the most important pathogen of infectious gummosis, and this type of gummosis usually exudes black, milky colloid from wounds.
Because peach tree gummosis is difficult to cure completely, prevention must be the priority, combining prevention with control. Specific measures include ridge cultivation, stabilizing tree vigor, balanced nutrition, spraying or drenching with Sea Elf biostimulant during physiological periods, reasonable crop load, and reducing tree damage. For areas that have already developed gummosis, high-concentration fungicides such as tebuconazole, carbendazim, thiophanate-methyl, lime sulfur mixture, and Bordeaux mixture can be brushed on.
2. Wood rot
It mainly damages the branches and trunk of peach trees, invading through wounds, destroying the fibrous tissue of the xylem, affecting nutrient transport, and reducing branch toughness so they break easily.
Old trees, weak trees affected by pests and diseases, and orchards with many wounds have severe incidence.
The diseased tree body can be pruned, the trunk scraped, and paint + tebuconazole applied for protection, while also paying attention to tree care and maintaining tree vigor.
