At the beginning of the disease, the affected part is slightly swollen, dark brown, and the surface is moist, and then the diseased part is concave and cracked, overflowing with light yellow translucent soft rubber blocks, and finally becomes amber-like hard rubber blocks, with a smooth and shiny surface. The growth of trees is weak, and when it occurs, it can cause some branches to dry up.

The disease can be caused by a variety of reasons, which can be roughly divided into physiological gel flow, such as frost damage, sunburn, wounds caused by mechanical damage, wounds caused by insect infestation, etc.; There is also infectious gum flow, bacteria and fungi can cause gum flow, and the pathogenic bacteria are not yet known. Prevention and control measures: (1) Scar scar application.

Scrape off the gum from the branches with a razor blade, and then apply the wound with combing agents and agents. (2) Strengthen management, pay attention to cold and frost protection in winter, and apply white or carding agent.
