Only sterilized potting medium should be used when repotting rubber trees, and water should be given sparingly during the growing season, taking care to keep the leaves dry. Crown Gall Crown gall is a bacterial infection affecting the roots and stems of rubber trees, caused by a bacteria called Agrobacterium tumefaciens.

Characterized by swollen areas along the stems, crown gall can cause large, disfiguring masses to appear, which are deadly to the plant. The roots can also be affected and are then inhibited from absorbing nutrients and moisture.

Unfortunately, there is no treatment for crown gall, and any infected plants must be destroyed to prevent the spread of the bacterium. Xanthomonas Leaf Spot Xanthomonas leaf spot is one of the most common diseases found in rubber trees.

Caused by a bacteria called Xanthomonas campestris, it is characterized by tiny oozing spots that appear on the leaves, eventually causing them to yellow and die.

The spots rapidly grow in size and are often bordered by bright yellow discolorations that spread between the leaf veins. Copper-based bactericides can keep the infection from spreading if applied early, although they can harm healthy tissue if overused. Xanthomonas leaf spot can be prevented if excessive watering is avoided and fertilizer is used sparingly.

Thrips Thrips are tiny winged insects known to attack rubber trees. Although some cultivars of rubber tree are resistant to thrip infestations, most commonly available ficus houseplants are susceptible to them.

They can be prevented and controlled with commercially available insecticide. Mealybugs Mealybugs are white, waxy insects that sometimes colonize the undersides of rubber tree leaves.

Early signs of a mealybug infestation include drooping or dry-looking leaves and the appearance of cotton-like masses along leaf attachment sites and on the undersides of the leaves.

Manual removal of mealybugs is difficult and seldom effective, although spraying the affected area with an alcohol and water solution can lessen the severity of the infestation.Pink-colored mycelial growth on the bark surface with streaks of latex oozing out from the lesions. Prakash.
