What is the reason for iron rust spots on Clivia leaves? What should I do if there are rust spots?

I. Reasons

1. Infectious diseases: iron rust spots appear on Clivia leaves, which may lead to diseases such as rust spots. After being infected with this disease, spots will appear on the leaves, and then the spots will deepen and enlarge, and gradually spread to all leaves, infecting other leaves, thus affecting the whole plant. 2. Infected by pests: This not only happens in infected diseases. Once infected with pests, such as red spiders, scale insects, etc., pests will adhere to the leaves to absorb water, which will also lead to rust spots on the leaves.

Second, what should I do if there are rust spots?

1. Leaf cutting: Rusty leaves should be cut off in time to prevent further spread of diseases, whether infected with pests or not. 2. Treatment of the disease: After the infection is confirmed, Clivia should be moved to a well-ventilated place and sprayed in time at the early stage of the disease. It can be sprayed with 20% thiophanate WP or 50% carbendazim WP 1000 times. 3. Treatment of pests: If the quantity is small, you can kill pests manually first. Spray it in time if it is serious. 4. Pay attention to maintenance: this situation is easy to occur in high temperature and high humidity environment. Keep good ventilation, disinfect and change soil regularly, which is not suitable for thick fertilizer or raw fertilizer.
