In-vitro compatibility studies of B. bassiana (Bb-5a) with ten insecticides were examined on PDA media by poisoned food technique to develop suitable combinations for the control of whitefly in sunflower ecosystem. Out of ten insecticides, nine insecticides viz., imidacloprid, thiamethoxam, acetamiprid, clothianidin, acephate, fipronil, buprofezin, flonicamid and azadirachtin showed compatible with B. bassiana at recommended dose (RD), half of the recommended dose (0.5 × RD) and double the recommended dose (2 × RD) at 14th and 30th DAI. Whereas, diafenthiuron inhibited the mycelial growth and showed incompatible with B. bassiana. Among the compatible insecticides, thiamethoxam, flonicamid, acephate, buprofezin and azadirachtin could be used with B. bassiana against whiteflies in the field condition. Efficacy study revealed that combined application of RD and 0.5 × RD of thiamethoxam, flonicamid, acephate, buprofezin and azadirachtin with B. bassiana showed synergistic effect in controlling the pests than their individual application. Among the compatible combinations, B. bassiana with thiamethoxam and flonicamid showed ≥ 90 per cent whitefly control followed by acephate, buprofezin and azadirachtin.
