The bio-agent, Beauveria bassiana was found to reduce 39.7 to 72.6% of white fly population in cotton. However, it was ineffective against jassids, as it could reduce only 10–14% of population. Neem oil was more effective against jassids (20.4–42.5% reduction) than that of NSKE. However, both the neem products tested (neem oil & NSKE) were found to reduce more than 50 % of whitefly population.
