How to prevent cherry tree gum disease
Fluidic gum disease generally occurs during the growing season and manifests itself as transparent gels that flow out of branches or branches. After the glue is poured, the cortex and xylem of the tree become brown and rot, and it is easy to infect other germs. As a result, the tree vigor is weakened for a long time. When it is severe, the branches die and even the whole plant dies. The gummy disease is a kind of physiological disease, which has a close relationship with the strength of the tree potential, the number of wounds, the cultivation and management and other factors. The prevention and control methods are: to strengthen the comprehensive management of orchards, to reduce the occurrence of pests and diseases; to minimize the cut when pruning, it is best to apply protective agent for large wounds and the diseased trunk (protection agent available lime 10 parts, stone sulfur Mixture of 1 part, 2 parts of salt, and 0.3 parts of vegetable oil with water), whitening the trunk, and preventing sunburn.
