Common diseases and pests of Chinese lantern tree and their prevention and control methods

Gummosis

Symptoms of gum disease

Gummosis mainly attacks the trunk and main branches of the plant. In the early stage of the disease, the infected area will become swollen, dark brown in color, and the surface will be relatively moist. Later, the infected area will become concave and cracked, secreting a yellowish, translucent soft gel, which will eventually turn into an amber-like hard gel with a very smooth surface. Infected plants will grow slowly, and in severe cases the branches will dry up.

Causes of gum disease

Gummosis can be caused by many reasons. When plants are damaged by frost, sunburn, mechanical damage, or insect pests, the wounds will produce physiological gummosis. Fungi and bacteria can also produce infectious gummosis.

Gummosis prevention and control

You can scrape the scars of the plants and apply medicine. Use a blade to scrape off the gelatinous substance on the branches and trunks, and apply combing agent and medicine on the wounds.

In winter, protect the plants from cold and frost. In hot summer, prevent sunburn and try to avoid mechanical damage.
