Abstract The efficacy of formulations of entomopathogenic fungi, Beauveria bassiana (Bb 112) against Bemisia tabaci in brinjal was evaluated under microplot condition. The best one was evaluated in brinjal under field condition using various delivery equipment in Kumarapalayam village of Coimbatore district and Ambillikai village of Dindigul district in randomized block design. The results revealed that the oil formulation of B. bassiana (Bb 112) gave maximum control (46.10%) when compared to talc (34.34%) and crude formulations (27.77%). Oil formulation of B. bassiana (Bb 112) sprayed with Controlled Droplet Applicator (CDA) gave the maximum population reduction (45.36% in Kumarapalayam; and 38.47% in Ambillikai). Hence, the present study implies that the improved formulations applied using improved delivery systems is effective.
