- Catch the moth using a sweep net either early in the morning or before sunset.
- 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.
- 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.
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.
