Laboratory studies revealed that 10% water extracts of sorghum and pearl millet grains and sunRower seeds (all at dough stage), cotton bolls and squares, and tomato fruits (both green and ripe) when added to nuclear polyhedrosis virus of Helicoverpa armigera (Hbn.) (HaNPV) significantly Increased the mortality due to virus in second instar larvae of H. armigera. Probit analysis of time-mortality response showed that the LT50s were also reduced in these treatments. Dust formulations of HaNPV containing extracts of sorghum grain, cotton seed kernel, chickpea flour and sunflower seed kernel were significantly more effective alalnst H. armigera larvae than the virus formulation without any adjuvant. Sorbic acid and methyl parahydroxy benzoate which Were used in the formulations were not responsible for the enhanced efficacy of the virus.
