Abstract

ABSTRACT Malathion 57EC, Dimilin 25WP and Atabron 5EC were tested for their efficacy against Piesmopoda obliquifasciella in the field. Trials were conducted in randomized complete block design with three replications. Malathion @ 0.05%, 0.1% and 0.2% gave 58.32, 78.52 and 82.59% and 71.2, 86.49 and 87.50% mortality after 24 hours and two weeks of spray, respectively against zero percent natural mortality (corrected mortality after Henderson and Tilton�s formula) Dimilin caused 47.29, 66.94% and 84.54, 88.14% mortality after one and two weeks of spray at 0.025 and 0.05% concentrations, respectively. Similarly 58.16, 73.17% and 80.38, 89.36% mortality was recorded against Atabron at 0.025 and 0.05% concentrations after one and two weeks of treatment against zero percent natural mortality. On the basis of these findings, Malathion @ 0.1%, Dimilin and Atabron @ 0.05% concentrations are suggested for effective and timely control of P. obliquifasciella.
