Curative Control

Physical control

  1. Catch the moth using a sweep net either early in the morning or before sunset.
  2. Cover the vines near the base (the first 15-20 cm from the base) with strips of used lady nylon stockings or any strips of very fine nets to prevent the adults from laying their eggs on them.
  3. Remove and kill the worm. To do so, make a lengthwise slit near the damaged area (on the vine) using a sharp knife. Then cover the vine with slightly moist soil to encourage rooting of the nodes.

  4. Always look for frass (shiny-green or sawdust-like excreta), usually visible on damaged areas, to make sure that the damage is not caused by a fungal and/or bacterial disease.
