Understanding the Pink Bollworm Problem
The Pink Bollworm (Pectinophora gossypiella) is one of the most destructive pests of cotton. Its larvae bore into cotton bolls and feed inside, damaging seeds and lint. This not only reduces the quantity of yield but also deteriorates the quality of cotton fiber, directly impacting farmers’ profits.
Climatic factors also influence its incidence. Warm and humid conditions favor rapid multiplication, meaning that climate change and irregular weather can further worsen Pink Bollworm infestations.
Why Is Pink Bollworm a Concern in India?
- High infestation levels have been reported across central and southern India, sometimes affecting up to 40–95% of bolls.
- Yield losses can range from 20–30% when infestations go uncontrolled.
- Resistance to Bt toxins (Cry1Ac and Cry2Ab) in Bollgard II cotton is in process and will be documented soon, making traditional genetic resistance alone insufficient.
- Carry-over through ginning and seed storage allows the pest to survive season after season.
- Inadequate refuge planting has accelerated resistance development.

Precautions Farmers Can Take
Farmers can protect their cotton crop by adopting Integrated Pest Management (IPM) practices rather than relying only on insecticides. Some important precautions include:
- Crop Rotation – Grow non-host crops in alternate seasons to break the pest’s life cycle.
- Selection of Resistant Varieties – Use cotton hybrids with stronger tolerance against Pink Bollworm.
- Balanced Use of Insecticides – Apply recommended insecticides at the right time and avoid overuse to prevent resistance build-up.
- Biological Control – Encourage natural enemies such as parasitoid wasps, predators, or beneficial fungi that attack Pink Bollworm larvae.
- Field Sanitation – Remove crop residues, unopened bolls, and stubbles after harvest to destroy overwintering larvae.
- Monitoring & Trapping – Install pheromone traps to detect pest presence early and take timely action.
- Weather-based Management – Adjust crop care practices according to climatic conditions, since temperature and humidity strongly affect pest activity.
Insecticide Recommendations
For Pink Bollworm control, agricultural experts often recommend:
- Profenofos
- Thiodicarb
- Chlorantraniliprole
- Emamectin Benzoate
These should be applied at specific crop stages (65–110 days after sowing) and in the right dosage. Farmers must consult local agricultural extension officers or experts for region-specific guidance.
Long-Term Management Approaches
To ensure future protection against Pink Bollworm, farmers should:
- Adopt short-duration cotton varieties that reduce pest exposure.
- Maintain refuge planting with non-Bt cotton to slow resistance development.
- Promote seed purity to ensure uniform toxin expression.
- Combine chemical, cultural, and biological methods for sustainable control.
Role of Biological Control
Biological control means using nature’s own enemies of pests instead of relying solely on chemicals. For Pink Bollworm, beneficial insects like parasitoid wasps or predators can reduce populations. This method is environmentally friendly, cost-effective, and reduces chemical dependency.
Introducing KRISH-45 BG II: A Stronger Solution
Amid these challenges, selecting the right hybrid makes a big difference.
KRISH-45 BG II is a cotton hybrid developed to provide better resistance against Pink Bollworm, with higher tolerance levels compared to many other hybrids.
Key benefits include:
- Enhanced protection against Pink Bollworm attacks.
- Stable yields even under pest pressure.
- Suitable for farmers seeking a safer, more reliable option in the Bollgard II segment.
- Complements IPM practices by reducing the pest load and pesticide dependency.
By integrating KRISH-45 BG II into farming systems, along with the best management practices listed above, farmers can protect their crop, safeguard yields, and reduce production risks.
Quick Checklist: How to Protect Cotton from Pink Bollworm
- Rotate crops and avoid continuous cotton.
- Use resistant varieties like KRISH-45 BG II.
- Apply insecticides judiciously and on time.
- Encourage biological controls.
- Install pheromone traps for monitoring.
- Remove leftover plant debris after harvest.
- Stay alert to weather patterns.
