Uttar Pradesh ranks number one in mango production in India, with large-scale mango cultivation across the state. However, mango trees are highly susceptible to various pests and diseases from flowering to fruit formation. Among the most harmful threats are hopper insects, midge pests, and powdery mildew disease, which can cause severe damage to the crop. If timely preventive measures are not taken, farmers may suffer significant losses.

Damage and Prevention from Hopper Pests:

Hopper pests suck the sap from new shoots, flowers, and young fruits, causing affected parts to dry out and fall off. This weakens the tree and reduces yield. Additionally, these pests secrete a sticky substance that leads to black fungal growth on leaves, hindering photosynthesis and weakening the plant.

 Prevention Measures:

• Spray 3 ml of Nimbicidine per liter of water at the flowering stage.
• Apply 0.2% Carbaryl or 1.3 ml Quinalphos per liter of water for a second spray.

Damage and Prevention from Midge Pests:

Female midge pests lay eggs in mango flower clusters and new shoots. The larvae feed internally, damaging the shoots and flowers, causing them to turn black and dry out.

 Prevention Measures:

• Spray 1.5 ml of Marshal or 1.5 ml of Contaf Plus per liter of water during the flowering and fruit-setting stages.

Damage and Prevention from Powdery Mildew Disease:

Powdery mildew appears as a white powdery fungal layer on mango fruits and stems. Affected parts turn yellow, then dry out, significantly impacting yield.

Prevention Measures:

• Spray 3 ml of Calixin per liter of water.
• Apply 2 grams of Indofil M-45 per liter of water.

Protecting Mango Orchards from Air Pollution:

Mango orchards near brick kilns are highly vulnerable to sulfur dioxide gas, which causes fruits to turn black and reduces market value.

 Preventive Measures:

• When fruits are pea-sized, spray 5 grams of caustic soda per liter of water.
• Apply 1 gram of micronutrients (Multimax or Vorex) per liter of water at the same time.

Precautions While Spraying Pesticides:

• Avoid spraying chemical pesticides when trees are in full bloom, as it can disrupt pollination and reduce fruit formation.
• Always spray early in the morning or late in the evening for maximum effectiveness.

Mango, known as the "King of Fruits," is a significant source of income for farmers. However, without timely pest and disease management, the entire crop can be ruined. By following expert advice and using appropriate pesticides and organic solutions, farmers can protect their orchards and ensure high-quality mango production.
