Distribution and Dangers of Green萝 (T-J) Disease
It occurs to varying degrees in different cultivation and introduction areas, and the leaves develop spots that are unsightly for viewing.
Symptoms of Green萝 (T-J) Disease
Irregular round spots appear on the leaf surface, near the edges or close to the main veins. The center of the spots is light-colored, appearing grayish-white, with the edges being brown to dark brown. Later, black dots appear on the spots, which are the fruiting bodies of the pathogen.

Conidia are spread by air currents or rainwater and irrigation water. The optimal temperature for the disease to occur is between 22 and 27°C, with a relative humidity of 85% to 95%. It can occur year-round in greenhouses or homes with heating.

▲ Upon detecting spots, promptly cut out the spots along with 1 cm of healthy tissue surrounding them. If the removal of spots affects the appearance, or if there are many spots, cut off the entire leaf.
▲ Apply pesticides for prevention and control. You can spray 50% Thiram wettable powder at 800 times dilution, 75% Chlorothalonil wettable powder at 600 times dilution, or 50% Methyl Thiophanate wettable powder at 800 times dilution at the early stage of the disease.
The above-sharing of the dangers and control measures of Green萝 (T-J) Disease can help you say goodbye to disease troubles in green plants and flowers, and we hope it can bring you help in your life!
