ABSTRACT

Ashwagandha or Asgandh (Withania somnifera Dunal.), is an important medicinal plant which is attacked by several insect pests including spotted leaf beetle, Epilachna vigintioctopunctata Fab. The present investigation was carried out to under field conditions. Results revealed that farmyard manure (FYM) (12.5 t/ha) + Azophos (2 kg/ha) + neem cake (1000 kg/ha) was found to be very effective in reducing the damage of spotted leaf beetle by 69.79 per cent. FYM + Azophos + neem cake combination was less preferred for oviposition which recorded 62.00 eggs/plants, coupled with a minimum feeding area of 6.75 cm2.
