Integrated Management of Pigeon Pea Pod Borers
Pigeon pea is one of the most popular pulse crops produced in most of India. This crop is cultivated in several regions as intercropped with maize or cotton. If appropriate care is not undertaken during the reproductive stage, different types of pod borers can cause economic harm. In addition to various pod borers, aphids, termites, mealy bugs, leafhoppers, mites, pod bugs, etc. are also found in this crop.
Among the pod borers, pod fly, blue butterfly, plume moth, spotted pod borer cause major damage during flowering and pod pea formation. The infestation of pod fly and pod borer is more frequent in mid-late and late varieties. In general, the pod borer population is more in bunching type pod’s variety. Pod borer larva enters the pod by making a hole and feeding the developing seeds. While the pod fly larva also entered the pod and fed inside. Initially, the plume moth larva scrapes the epidermal layer of pods and then enters and feeds the seeds.
• Destroy the weed host plants from the bunds and boundaries of the field as they also survive on them.
• The population of pod borers are generally low in non-bunches (scattered pods setting on twig) pigeon pea varieties.
• The infestation is lower in pigeon pea cultivated as intercrop with maize crop.
• Install 5 traps for pod borer (Helicoverpa) on initiation of flowering and if sufficient number of catches are observed, install further more traps
• Install one light trap in the field, if electricity is manageable.
• On initiation of pests, spray neem seed kernel powder 500 g per 10 litre of water (5%).
• Spray HaNPV @ 250 LE per hectare.
• Spray Bacillus Thuringiensis (BT) powder @15 g or Bouveria Bassiana fungus base powder @40 g per 10 litre of water.
• Plan to attract more number of predatory birds in the field.
• At flowering on 50% plants, spray Acephate 75 SP @15 g or Emamactin Benzoate 5 SG 3 g or Indoxacarb 15.8 EC 4 ml or Thiodicarb 75 WP 20 g or Chlorantraniliprole 18.5 SC 3 ml or flubendiamide 480 SC 3 ml or spinosad 45 SC 4 ml or deltamethrin 1% + Triazophos 35% EC 10 ml or Flubendiamide 20 WG 5 g or Chlorpyriphos 50% + Cypermethrin 5% EC 10 ml or Profenophos 40% + Cypermethrin 4% EC 10 ml per 10 liter of water. Change the insecticide at every spray.
• Do not spray Monocrotophos in pigeon pea grown for vegetable purpose.
