Description Two seasons experimentation for management of H. armigera in Virginia tobacco, by integrating trap crop and bio-pesticide, neem seed kernel extract (NSKE) revealed a significant reduction in budworm infestation in Virginia tobacco plots with trap crops + NSKE spray as compared to plots with trap crop and without NSKE spray. All the trap crops planted around Virginia tobacco plots sprayed with NSKE recorded significantly higher number of eggs and larvae as compared to trap crops planted around tobacco without NSKE spray. The natural enemy activity was not affected and was found to be more on tobacco with marigold- mw as trap crop. Conjunctive use of trap crops, marigold- SW or rustica tobacco with NSKE spray was effective for management of budworm, H.armigera in Virginia tobacco and also resulted in better grade index.
