Controlling Mango Malformation Disease in Indian Mango Trees

Definition: Mango malformation disease is a fungal infection caused by Fusarium mangiferae that affects mango trees, particularly in India. It leads to the abnormal growth of vegetative and floral parts, resulting in reduced fruit yield and quality.

Symptoms of Mango Malformation Disease

1. Vegetative Symptoms:

• Excessive branching
• Stunted growth
• Malformed leaves
• Twisted or distorted shoots

2. Floral Symptoms:

• Malformed flowers
• Abnormal flower clusters
• Flower necrosis
• Reduced flower production

Control Measures for Mango Malformation Disease

1. Cultural Practices:

• Pruning: Regularly prune infected branches to remove the source of infection and promote healthy growth.
• Sanitation: Clean the orchard by removing fallen leaves, diseased plant debris, and weeds to reduce the spread of the fungus.
• Proper Irrigation: Avoid over-irrigation, as excessive moisture can create a favorable environment for fungal growth.
• Soil Management: Maintain proper soil drainage and fertility to enhance the tree’s resistance to diseases.

2. Chemical Control:

• Fungicides: Apply fungicides recommended by agricultural experts during the dormant season or at the first sign of disease to control the spread of the fungus.
• Systemic Fungicides: Use systemic fungicides that can be absorbed by the plant and provide long-lasting protection against the disease.

3. Biological Control:

• Biocontrol Agents: Introduce beneficial microorganisms or fungi that can suppress the growth of Fusarium mangiferae and prevent the spread of the disease.

4. Integrated Pest Management (IPM):

• Monitoring: Regularly inspect the orchard for early signs of disease and take appropriate action.
• Integrated Approach: Combine cultural practices, chemical control, and biological control methods to effectively manage mango malformation disease.

By implementing these control measures, mango growers in India can minimize the impact of mango malformation disease on their orchards and ensure healthy mango tree growth, leading to improved fruit yield and quality.
