How to Treat Anthracnose in Monstera deliciosa? Detailed Prevention and Control Methods

I. Symptoms

When it suffers from anthracnose, the affected area is mainly the leaves. In the early stage of the disease, irregular brown spots appear on its leaves, and afterward, as time goes on, these leaves slowly turn grayish-white, and many small black dots grow on the spots. This not only affects the plant's growth but also greatly affects its appearance.

II. Pattern of Onset

The pattern of this disease is usually that the mycelium remains on diseased leaves to overwinter, and then when spring comes the following year, they continuously produce spores, which are then spread by wind and rain, causing the disease. This disease is usually more likely to occur in relatively hot and stuffy weather, and in severe cases, it can cause all the plant's leaves to scorch or fall off.

III. Prevention and Control Methods

1. First, strengthen management of it; you can apply a bit more organic fertilizer to enhance its constitution and improve its resistance.

2. Second, do not water the leaves, and at the same time appropriately reduce air humidity during rainy periods.

3. Finally, when disease is found, promptly cut off the diseased leaves and burn them, and at the same time spray some medication on the plant, which can also achieve a very good therapeutic effect. Spray once every 10 days, for a total of 2 to 3 sprays.
