Margo Delfin WG Insecticide is a biological insecticide containing Bacillus thuringiensis var. kurstaki (Bt), widely used for the control of caterpillars and leaf-eating larvae in various crops. It works through stomach action; when the larvae feed on treated leaves, the bacteria release toxins that stop feeding and eventually kill the pests. Margo Delfin WG is highly effective against pests like Helicoverpa (fruit borer), Spodoptera (armyworm), diamondback moth (DBM), and other lepidopteran larvae. It is safe for beneficial insects and environment-friendly, making it suitable for Integrated Pest Management (IPM) programs. The product is commonly used in vegetables, cotton, pulses, and horticultural crops to reduce leaf damage and improve crop health and yield.

Composition: Bacillus thuringiensis var kurstaki (Btk)

Dosage:
• 0.5–1 g per liter of water
• 200–300 g per acre

Application Method:
• Spray uniformly on both sides of leaves
• Ensure thorough coverage of the foliage, especially young leaves
• Use sufficient water for proper leaf wetting

Targeted Pests:
• Helicoverpa (Fruit Borer) → Controls fruit and pod damage
• Spodoptera (Armyworm) → Reduces leaf feeding and defoliation
• Diamondback Moth (DBM) → Protects crucifer crops from larval damage
• Leaf Eating Caterpillars → Stops feeding activity on vegetables and field crops
• Lepidopteran Larvae → Controls early-stage caterpillar infestation

Timing:
• Spray during early morning or evening hours
• Avoid spraying during strong sunlight or high temperature

Frequency:
• Repeat after 7–10 days if pest infestation continues
• Apply at early larval stage for best effectiveness

💡 Best Results Tip:
Use clean water and ensure pests actively feed on treated leaves for effective biological control action.

• Helps naturally reduce caterpillar population without disturbing crop ecology
• Protects young leaves from early chewing damage and surface injury
• Maintains crop cleanliness by preventing irregular leaf feeding patterns
• Supports healthier plant development by reducing continuous larval pressure
• Preserves beneficial insects that help in natural pest balance
• Helps maintain uniform crop appearance across the field
• Reduces hidden larval activity on the underside of leaves
• Improves plant resilience by minimizing repeated defoliation stress
• Supports better flowering by ensuring less foliage damage during growth stages
• Contributes to safer produce quality suitable for export and residue-conscious farming systems

Vegetative Stage → Controls early infestation of leaf-eating caterpillars in Vegetable Crops, protecting young foliage and plant growth
Flowering Stage → Protects flowers and tender parts of Cotton and Pulses from larval feeding damage, supporting better crop development
Fruiting / Pod Development Stage → Reduces caterpillar damage in developing fruits and pods of Tomato, Chilli, and Brinjal, helping improve yield and quality

• Wear gloves and mask while spraying
