When indoor temperature fluctuates greatly in a short period of time, or too much watering during dormancy, lotus bamboo is also prone to leaf spot disease. The disease mainly causes harm to the lower leaves of the lotus bamboo, the diseased leaves will appear many small brown spots, in serious cases will spread throughout the leaves.

In the prevention and control of lotus bamboo diseases and insect pests, anthracnose is also something that everyone needs to prevent. The disease easily occurs when the humidity is too high and the environment is not ventilated in the rainy season. If the leaf tip of the lotus bamboo turns black and the leaves have yellow spots, it should be suffering from anthracnose.

Prevention and treatment methods: when the above diseases are found, if it is winter and spring, the diseased leaves should be removed and destroyed in time, and the soil should be disinfected with quicklime. At the initial stage of the disease, 75% chlorothalonil 600 times or 50% thiram wettable powder 500 times can be sprayed once every 7 to 10 days, 3 times in a row.
