A field experiment was conducted to evaluate insecticides against the whitefly Bemisia tabaci Genn. in potato at the Agricultural Research Station, Kota, using variety K Bahar during 2018-19 and 2019-20. Based on pooled data, results revealed that two sprays of diafenthiuron 50WP 350 g a. i./ha mixed with castor oil @ 0.05% at 10 days interval gave maximum mortality (82.0%), maximum tuber yield (24.7 t/ha) with incremental cost benefit ratio (ICBR 1:2.1) which was at par with two sprays of diafenthiuron 50WP 350 g a. i./ha (without mixed castor oil) at 10 days interval (78.0%) with tuber yield (23.8 t/ha).
