Terai Zone
- Paddy Water Management: Maintain a 2-3 cm water level in paddy fields.
- Khaira Disease Control: To control Khaira disease (due to Zinc deficiency), spray chelated Zinc @ 0.5-1.0g per litre of water during clear weather.
- Epilachna Beetle in Bitter Gourd: At the fruit maturity stage, remove and burn eggs and baby beetles at the initial stage of infestation. For high infestation, apply Carbaryl @ 2.5g, Carbosulfan @ 2ml, or (Chlorpyriphos + Cypermethrin) @ 1.5ml per litre of water during clear weather.
- Fruit and Shoot Borer in Chilli: Remove and burn all infected plant parts to control fruit and shoot borer.
Old Alluvial Zone
- Blast Disease in Aman Paddy: Avoid top dressing with nitrogenous fertilizer if blast disease is present. Apply Potassium @ 5-6 kg per bigha as top dressing during fair weather.
- Powdery Mildew in Pointed Gourd: If powdery mildew is observed, spray Carbendazim @ 5g or Zineb @ 20g per 10 litres of water during clear weather. Provide additional support to pointed gourd plants to prevent lodging.

- Cauliflower Water Management: Ensure proper water removal arrangements to prevent wilting in cauliflower.
Laterite and Red Soil Zone

New Alluvial Zone
- Sheath Blight in Rice: High humidity and water stagnation favor sheath blight development. Drain excess water, reduce nitrogen fertilizer use, and apply biofungicides like Trichoderma or Pseudomonas Fluorescens.
