Management

• Use pheromone traps
• Destroy infected bolls
• Follow timely sowing
• Use recommended insecticides when necessary

2. Whitefly

Damage Symptoms

• Sucking of plant sap from leaves
• Yellowing and curling of leaves
• Honeydew secretion causing sooty mold
• Transmission of cotton leaf curl virus

Management

• Avoid excessive nitrogen fertilizer
• Install yellow sticky traps
• Maintain field sanitation
• Use suitable systemic insecticides

3. Aphids

Damage Symptoms

• Leaf curling and yellowing
• Sticky honeydew secretion

• Monitor early infestation
• Use need-based sprays

4. Jassids

Damage Symptoms

• Yellowing at leaf margins
• Leaves curl downward
• Hopper burn symptoms
• Reduced plant vigor

Management
