Management of Pod Borer in Chickpea (IPM)
Chickpea is grown in India as irrigated or non-irrigated in the winter season. Right from sowing to harvesting, only' Pod borer' is reported to cause damage to this crop. The recently formed larvae first scrape the epidermal layer of young leaves or seeds. This larva is polyphagous in nature and a voracious feeder which is harmful to several crops. At the time of pod forming, larvae make a hole in the pod and feed the egg. Occasionally, larva enters the pod and eats seeds that develop.
• Install pheromone traps @ 40 per hectare.
• Also install one light trap, if electricity is nearby.
• Spray HaNPV @ 250 LU per hectare.
• Install T-perches to attract the predatory birds.
• On initiation, spray Beauveria bassiana, a fungus base insecticide @ 40 g or Bacillus thuringiensis, a bacterial base powder @ 15 g per 10 liter of water.
• Do not spray any chemical insecticides if crop is grown for green pods purpose. Instead of it, spray neem based formulations @ 20 ml (1% EC) to 40 ml (0.15% EC) per 10 liter of water.
• Naffatia or ardushi or Kadvi Mehdi or Jatropha leaves extract @ 5% can also be sprayed for the control of pod borer at initial stage.
• If possible, raise marigold as trap crop in and around the field.
• On higher population, spray Fenvalerate 20 EC @ 10 ml or Lambda Cyhelothrin 5 EC @ 5 ml or Lufenuron 5 EC @ 10 ml or Thiodicarb 75 WP @ 20 g or Chlorantraniliprole 18.5 SC @ 3 ml or Emamectin benzoate 5 SG @ 5 g or Flubendiamide 20 WG @ 5 ml per 10 liter of water.
• Bigger larvae may not be controlled by any of the insecticides; it is better to opt for hand picking and destroy them.
