(Ratoon Crop)


Stage Disease Management
Ratoon initiation Scales, mealy bug, pyrilla, black bug, woolly aphid and army worm Stubble shaving, removal of water shoots and late shoots, burning of crop debris.
Stubble sprouting to June Termites Chlorpyriphos @ 1 kg a.i./ha through irrigation water.
  Shoot borer, root borer, top borer Collection and destruction of egg masses and infested shoots.
  Scales, mealy buds Spraying with Malathion (0.1%) or Dimethoate (0.08%) after detrashing at 4-5 internode stage.
  Black bug Spray with Chlorpyriphos or Quinalphos @ 0.2 kg a.i./ha.
  1. Redistribution of Epiricania melanoleuca cocoons and egg masses from high population bearing fields to low population ones by stapling cocoon/egg masses bearing leaf pieces on lower surface of leaves.
  2. If parasitoid is absent, chemical spray can be undertaken provided chemical does not kill the parasitoid.
  3. Foliar spray of Metarhizium anisopliae @ 106-107 spores/ml.
  4. Release of adults of pyrilla infested with M. anisopliae spores @ 250 adults/ha.
  White fly Spraying with Acephate (0.1%) or Confidor (0.05%).
  Woolly aphid Pockets of infested clumps may be sprayed with Metasystox (0.05%) 2 times at 15 days interval during summer months.
July to August White grub
  1. After first shower of monsoon, adult beetles should be collected from the nearby trees and killed.  For effective collection light trap may be used.
  2. When adult (beetles) emerge, soil application with Quinalphos 5G @ 2.5 kg a.i./ha.
  Woolly aphid
  1. Release of predaots (Dipha aphidivora or Micromus igorotus in infested field where predator activity is absent or low.
  2. In case of stray incidence of the pest, detrash the infested leaves and burn.
July to October Stalk borer, internode borer, root borer
  1. Release of T. chilonis @ 50000 parasitised eggs/ha at 10 days interval.
  2. Release of Cotesia flavipes @ 500 mated females/ha at weekly intervals till November.
  Gurdaspur borer Destruction of infested canes with gregarious stage of the pest.
September till harvesting Stalk borer
  1. Detrashing of dried foliage at 30 days interval.
  2. Removal of late shoots at 15 days interval.
  3. Spray of Monocrotophos @ 0.75 kg a.i./ha on detrashed canes (recommended for ring planted canes).
  Plassey borer Harvesting should be finished by February end.
