Abstract

Studies were conducted to potentiate 'NPV of Spodoptera litura by biochemical adjuvants for maximisation of control of the pest in FCV tobacco 'nurseries and field crop. The studies established that addition of tannic acid 0.25% and boric acid 0.35 % gave maximum efficacy. The significance of this finding is that boric acid and tannic acid, the com;nonly used chemicals in tobacco culture, are not only compatible with NPV but also potentiate it thereby satisfying the basic concept of compatibility of entamoviruses with agricultural chemicals.
