Root rot is caused primarily by soil-borne fungi such as Phytophthora and Fusarium species. These pathogens thrive in waterlogged soils, leading to the decay of roots, which turn black and mushy. The disease is often characterized by yellowing leaves, stunted growth, and wilting. If left untreated, root rot can lead to the complete death of the mango tree. The fungi attack the roots, impeding the tree's ability to absorb water and nutrients, which is critical for the tree's growth and fruit production.
Damping off, on the other hand, primarily affects young seedlings and is caused by fungi like Pythium, Rhizoctonia, and Fusarium. This disease is characterized by the sudden collapse of seedlings after they emerge from the soil. The base of the seedlings appears water-soaked and mushy, making it difficult for the plant to absorb nutrients and water. This rapid deterioration often leads to the death of the seedlings, severely impacting mango cultivation.
Effective management of these diseases involves a combination of cultural and chemical strategies. For root rot, improving soil drainage is essential. Planting mango trees on raised beds or mounds and avoiding overwatering are key practices. Fungicides can be used to treat infected trees, though natural remedies like cinnamon and hydrogen peroxide are also gaining popularity for their environmental safety and effectiveness.
To prevent damping off, using sterilized pots and soil, ensuring good air circulation, and avoiding overwatering are critical. Close monitoring of seedlings is necessary, and any infected plants should be removed immediately to prevent the disease from spreading.
By adopting these management strategies, farmers can significantly reduce the incidence of root rot and damping off, thereby improving the health and productivity of mango trees.
