Control of cowpea pod borer

  • Then caterpillars bore into the pods and feed on the seeds.    
  • If flowers and pods are not available, larva feeds on foliage.
  • Application of deep plowing and clean cultivation to expose the resting pupae and crop rotation reduce the pest population.
  • Use tolerant/resistant varieties.
  • Fix 3 feet sticks in the field @10/ha as bird parches to attract predatory birds  
  • Spray chlorpyrifos 20% EC 450 ml/ acre or indoxacarb 14.5% SC @ 160-200 ml/ acre.
  • Spray solution of emamectin benzoate 5% SG@ 100 gm/acre.

Control of pod borer in moong

  • Due to larvae being mature, they cause extensive damage by eating pods from inside.
  • After infection by the pod borer larvae, the pod is desiccated and dried in an early stage.
  • Before sowing, make deep plowing of the field and destroy insects eggs and cocoons in the soil.
  • Selection the short duration varieties of moong for sowing.
  • Maintain a certain distance between moong plants.
  • Spray Chlorpyrifos 20% EC 450 ml/ acre or Indoxacarb 14.5% SC@ 160-200 ml/ acre.
  • Spray solution of Emamectin Benzoate 5% SG@ 100 gm/acre.

Management of pod borer in Gram(Chickpea)

Pod borer in Gram (Chickpea):Pod borer is a pest that causes heavy damage to chickpea. In fact, this pest is reported to have caused yield loss up to 21%. The pest is reported to cause about 50 to 60%  damage to the chick pods. Apart from chickpea the pest also attacks pigeon pea, sunflower, cotton, chilli, sorghum, groundnut, tomato and other agricultural and horticultural crops. It is a devastating pest that attacks pulses and oilseeds.

Infestation: The infestation starts usually a fortnight after germination and becomes serious just after the initiation of flower bud coupled with cloudy and humid weather. Female lay several small white eggs. Upon hatching in 3-4 days the caterpillars feed on the leaves for a short time and subsequently attack the pods. A full-grown caterpillar is about 34 mm long, greenish to brownish in colour with scattered, short, white hair and buries itself in the soil to make an earthen cell inside which it pupates. The life cycle is completed in about 30-45 days. The pest completes eight generations in a year.

Management:-  It is advised to plough in summer to expose the hidden stages of the pest to natural predators. Application of HaNPV at the rate of 100 LE per acre along with 0.5 % jaggery and 0.1% boric acid specifically at the egg hatch stage should be done and it should be repeated in 15-20 days. Use of accurate chemicals should comprise 2.00 ml profenophos 50 EC per litre of water. Use of pheromone traps at 4-5 traps/ ha. spraying neem seed kernel extract 5% in the early stage. If the infestation is severe, spraying 0.5 ml Indoxacarb 14.5% SC or 0.1 ml Spinosad 45 SC or 2.5 ml Chlorpyriphos 20 EC can be helpful. Use of 4-5 bird perches to attract birds and sowing bhendi or marigold around the field as trap crops are the most effective way to deal with this pest.

Control of Gram pod borer in Soybean

Control of Gram pod borer in Soybean

Symptoms of damage:-

  • The young larvae feeds on the chlorophyll of young leaves and skeletonize it.
  • They feed voraciously on the foliage in early stage,may defoliate the plant and later they feed on flowers and pods.

Management:-

  • Deep summer ploughing
  • Install pheromone traps at a distance of 50 Meter @ 5 traps/ha for each insect pest.
  • Clip terminal shoots on 100 days of crop growth.
  • Spray with Chloropirifos 20% EC @ 750 ml/acre or Quinolphos 25% EC @ 250 ml/acre
  • Spray Deltamethrin 2.8% EC @ 250 ml/acre or Flubendiamide 20% WG @ 100 gm/acre

Management of Pea Pod Borer

Pea Pod Borer:- The larva of this insect cuts the pedicel of the flower and feeds on the stalk. Single larva damages many flower stalks. The larva feed on the leaves initially stage then bore in to the basal portion of stalks and inter the pod feeds on soft grains.

Management:- Plough deeply, Clean cultivation to expose the resting pupae. Trap cropping with crops likes Tomato and destroying them when the population is high and mechanically remove the adults and larvae from the trap crop. Use of inter crops like maize cow pea and brinjal significantly helps in reducing the pest population. Install the bird perches in the field. Application of HaNPV at the rate of 100 LE per acre along with 0.5 % jiggery and 0.1% boric acid at egg hatch stage and repeat at 15-20 days. Use of chemicals should comprise 2.00 ml profenophos 50 EC per litre of water as ovicides. Spraying neem seed kernel extract 5% in the early stage. If the infestation is sevre, spraying 0.5 ml Indoxacarb 14.5% SC or 0.1 ml Spinosad 45 SC or 2.5 ml Chlorpyriphos 20 EC can be applied.
