Insect Pestगुलाबी सुंडी (कपास)Parts: Flowers, Fruit/Pods
Pink Bollworm (Pectinophora gossypiella)
Affects: Cotton
Primary Chemical Cure
Chlorantraniliprole 18.5% SC (Coragen) or Emamectin Benzoate 5% SG
60 ml Coragen or 100 gm Emamectin Benzoate per acre in 150-200L water.
Economic Threshold (ETL)
1 live larva per 10 green bolls or 8 moths per pheromone trap per night for 3 consecutive nights.
Initiate spray only when crossed
Bio & Organic Option
Install 5-8 Pheromone Traps/acre with Pectino-lure; release Trichogramma bactrae egg parasitoids @ 60,000/acre at weekly intervals.
Key Visual Diagnostic Symptoms
Inspect Flowers and Fruit/Pods in the field for these definitive physical manifestations:
- Rosetted flowers that fail to open normally ("rosette flower" symptom).
- Small entrance hole plugged by excreta on developing cotton bolls.
- Premature boll opening, stained lint, and hollow damaged seeds.
Weather & Climate Factors Fueling Outbreaks
Dry, warm weather (28°C to 35°C) with relative humidity 60-70%.
Track real-time rain and humidity on our Aaj Ka Mausam Radar to preempt epidemics.
Preventive Agronomic & Cultural Controls
- Avoid planting unapproved ratoon cotton crops.
- Deep summer ploughing to expose hibernating pupae to solar heat and predatory birds.

Frequently asked questions
The recommended chemical control is Chlorantraniliprole 18.5% SC (Coragen) or Emamectin Benzoate 5% SG, applied at 60 ml Coragen or 100 gm Emamectin Benzoate per acre in 150-200L water.. Ensure complete foliage coverage, spraying during early morning or evening hours.
1 live larva per 10 green bolls or 8 moths per pheromone trap per night for 3 consecutive nights.. Chemical sprays should only be initiated when the pest population or disease incidence crosses this threshold to avoid unnecessary spray costs and pesticide resistance.
Yes. Install 5-8 Pheromone Traps/acre with Pectino-lure; release Trichogramma bactrae egg parasitoids @ 60,000/acre at weekly intervals.. Combining biological controls with cultural practices like crop rotation and removing infected plant debris offers sustainable control without chemical residues.
Pink Bollworm (Pectinophora gossypiella) predominantly infects Cotton, attacking the Flowers, Fruit/Pods.
