摘要：Field tests were conducted to evaluate the effect of Spodoptera litura (Fab.) nuclear polyhedrosis virus (NPVS)
alone and in combination with endosulfan and neemarin (neem seed kernel extract) against S. litura in cabbage.
Treatment with NPV-S (500 LE/ha) + Endosulfan (625 ml/ha) was better in reducing the larval population and
increasing yield than other treatments. However, considering cost benefit ratio (CBR), treatment with endosulfan
(1250 ml/ha) alone was found to be the most beneficial as compared with other treatments.
