Purple Potion Prevents Peach Tree Glue Disease
Peach tree gum disease is a non-invasive condition that typically starts with sap flow in early spring. It often appears on branches or wounds, especially after rainy periods. The disease is commonly associated with various factors such as frost damage, insect infestations, and mechanical injuries caused by pests like longhorn beetles, aphids, and stinkbugs. If these wounds are not properly treated, they can lead to excessive sap exudation, known as "gummosis."
In 2001, the author conducted an experiment on 20 mu of old, low-yield peach trees to prevent this issue. The method involved using scented water, and the results were impressive—achieving a prevention rate of 95.2%. This was significantly higher than the control groups, which had only a 50% resistance rate and a 300-times diluted liquid solution, showing an 11.7% improvement.
The treatment method recommended is simple but effective: before the trees start blooming in spring, use a scraper to remove the hardened gum deposits along the affected areas. Then, apply medical gentian violet to the wounds, repeating the process every five days for up to three times. This approach has proven successful in stopping the disease and promoting healing.
Additionally, the author experimented with alternating applications of a 3% cresol guaiacol soluble solution diluted 1000 times and purple syrup. This combination achieved an impressive control rate of 98.5%, making it a promising option for fruit farmers looking for natural and effective treatments. By combining traditional methods with modern solutions, growers can better manage peach tree gum disease and improve overall orchard health.
