1. Causes: as an indoor ornamental plant, its incidence is still very high, mainly because the virus grows in the hidden place of the plant, and then spreads and destroys the plant with the help of natural forces. Getting this disease will make the leaves grow round little black spots, but when it grows up, the black spots will be directly enlarged, and when those black blocks are connected, the whole plant will die directly.
2. Solution: cut off the leaves where the disease occurs, choose a sharp and sterilized scissors, and then destroy them, so as not to threaten the whole plant. To put it in the temperature of about 10 degrees, should not be too low, and then spray the whole plant, put it in a windy place for maintenance.
After the onset of the disease, we should immediately use carbofuran with water. If the situation is not very serious, we can spray it directly. Spray it every ten days. But if the situation is serious, we need to use scissors to cut off the bad places, and then apply the medicine. After curing for a period of time, its leaves will gradually recover. After it recovers, it is also necessary to spray medicine to it every two months.
