abstract
Investigations were carried out to evaluate the efficacy of formulations of Beauveria bassiana (Bb 112) against whitefly, Bemisia tabaci on tomato under microplot condition. Among the different formulations tested viz., crude, talc and oil formulations, B. bassiana (Bb 112) oil formulation was most effective against whitefly on tomato with 45.86 % reduction in population over control followed by talc (29.62 %) and crude formulations (21.63 %). Present study wide open the scope of using an oil formulation of B. bassiana (Bb 112) against other sucking pests also.
