Online published on 24 October, 2019. Abstract Field experiments were conducted to evaluate the efficacy of certain insecticides and botanicals against rice whorl maggot Hydrellia philippina Ferino at the RWRC Malan, Himachal Pradesh. Three insecticides viz., monocrotophos, dinetofuran and chlopyriphos were compared with four botanicals viz., eupatorium, The results revealed that the monocrotophos 36 SL sprayed 15 days after the second spray at 850 ml ha−1 was the best. The plots sprayed twice (25 and 45 days after transplanting) with dinotefuran and chlorpyriphos followed next. The results revealed that dinotefuran can be recommended. Among the botanicals, eupatorium (2500ml/ha) showed significant activity, and its spray formulation was superior.
