Abstract
Wettable powder and dust fonnulations of nuclear polyhedrosis virus @ 4.6 × 106 POB/pot were as effective as chlorpyriphos 0.04% spray or carbaryl 5% dust against thIrd Instar larvae of Spodoptera litura (F.) on groundnut plants in pots. The virus formulations however were inferior to the unformulated virus. At higher doses, the wettable powder (0.8 × 103 POB/pot) and dust (1.2 × 108 POB/pot) formulations gave control equivalent to unformulated virus (0.8 × 108 POB/pot). The leaf damage could be significantly reduced in all the treatments.
