蟹爪兰 has a very high ornamental value and stays green throughout the year. When it blooms, the cute flower buds, large ones look like little chili peppers, and the small ones look like grains of rice. When cultivating蟹爪兰, we often encounter many problems. For instance, the white spot disease. When you encounter this type of disease, how to effectively solve it?

For the prevention and treatment of white spot disease, let's first understand what it is. White spot disease commonly affects the leaves, and in the early stages of the disease, round to irregular spots can be seen on the center or base of the leaves of蟹爪兰.
In the middle stage of the disease, the spots continue to expand and can be seen on both sides of the leaf surface, appearing as purple-red or reddish-brown spots. In the later stage, the spots are red-brown or purple-red, with a clear boundary from the healthy tissue of the leaf.
White spot disease in蟹爪兰 is most likely to occur at temperatures between 22-28 degrees Celsius and humidity of 95%. Especially in warm spring, indoor temperature, and humidity, these conditions are conducive to the expansion of the disease. When蟹爪兰 is affected by the disease, the leaves become dry, severely affecting growth and ornamental value.
For the prevention and treatment methods of white spot disease in蟹爪兰, it is important to choose a deep soil layer with slightly acidic sandy loam as the growing medium. Maintain soil breathability and looseness.
Do a good job in watering and fertilizing regularly, avoid waterlogging and severe fertilizer damage. In summer, pay attention to shading and maintain a ventilated environment, and in winter, take good warming measures.
In the early stage of white spot disease, when the condition is not severe, you can clean the leaves with alcohol. Remove the diseased leaves of蟹爪兰 and spray some myclobutanil solution.
In severe cases, you can use a 25% benomyl·cycloheximide emulsion at 800 times or a 50% methylthiophanate·sulfur suspension at 800 times to spray and kill, until completely eradicated.
