That’s why timely whitefly control in cotton using proper methods and insecticides is very important to protect crop health and improve yield.

Problem Identification (Whitefly in Cotton)

Whiteflies are small, soft-bodied insects found on the underside of leaves. They suck sap from plants and weaken crop growth.

Lifecycle of Whitefly

  • Eggs are laid on the underside of leaves
  • Nymphs feed on plant sap
  • Adults multiply quickly in humid conditions

Why Whitefly Increases During Monsoon

  • High humidity

  • Sticky honeydew on leaves
  • Black sooty mold formation
  • Curling and drying of leaves
  • Weak plant growth

Damage to Cotton Crop

Whiteflies cause serious damage:

  • Reduce photosynthesis
  • Slow down plant growth
  • Cause flower and boll drop
  • Spread viral diseases like leaf curl virus
  • Reduce yield and crop quality
