Efficacy of Newer Insecticides against Bud Fly (dasyneura Lini Barnes) in Linseed

Experiments on newer insecticides viz., imidacloprid @ 0.0045%, acetamiprid @0.004%, thiomethoxam @ 0.005%, abamectin @ 0.0009 %, fipronil @ 0.01%, thidicarb @ 0.075%, spinosad @ 0.0096 % and indoxacarb @ 0.006 % were carried out to test their efficacy against bud fly on linseed during Rabi 2008-09 and 2009-10. Results revealed that spinosad @ 0.0096 % gave significant lowest bud fly infestation i.e. 9.4 per cent with higher per cent reduction (80.2 per cent) over control. The highest yield (1889.6 kg/ ha) was obtained in spinosad @ 0.0096 % treated plot followed by thiomethoxam 0.005 % (1632.00 kg/ ha).
