Abstract

An experiment was conducted in randomized block design at KVK Bhilwara, Maharana Pratap University of Agriculture and Technology, Udaipur to evaluate the efficacy of carbosulfan 25% EC at 250, 312.5 and 375 g a.i./ ha in comparison thiamethoxam 25% WG at 25 g a.i./ha, imidacloprid 17.8 SL at 25 g a.i./ha and acetamiprid 20% SP at 10 g a.i./ha against aphid (Myzus persicae) in cumin during Rabi, 2013-14 and 2014-15. The results revealed that two sprays of carbosulfan 25% EC at 375 g a.i./ha were effective against aphid. It caused maximum mean reduction in aphid population after second spray at 10 days after application, which was 87.52 and 88.45 per cent during 2013-14 and 2014-15, respectively. It was followed by carbosulfan 25% EC at 312.5 g a.i./ha. The highest yields were recorded in case of carbosulfan 25% EC at 375 g a.i./ha, which were 622.3 and 456.7 kg/ha during 2013-14 and 2014-15, respectively and incremental yield of 358.6 kg/ha over untreated control.
