Abstract The field experiment conducted during rabi 2015–16 at the Agricultural Research Station, Annigeri(Karnataka) for themanagement of safflower aphid through in secticidal seed treatment revealed that seed streated with imidacloprid 70WS@5gkg−1 seeds, imidacloprid 600FS@5ml kg−1 seeds and acetamiprid 20SP@5gkg−1 seeds recorded significantly lowest aphid population of (28.04,32.07 and 33.43 aphids 5cm apical twig−1, respectively) which were superior over other seed treatments and recorded higher seed yield of 9.67,9.38and 9.16qha−1, respectively. The next best treatments were the seeds treated with thiamethoxam70WS@5gkg−1 seeds and fipronil 5SC@5ml kg−1 seeds which recorded aphid population of 35.70 and 35.08 aphids 5 cm apical twig−1, respectively with seed yield of 8.52 and 7.96 q ha−1, respectively which were superior over untreated control. Similarly, imidacloprid 70 WS @5 g kg−1 recorded highest B:C ratio(1:1.95) followed by imidacloprid600FS@5ml kg−1 (1:1.89) and acetamiprid20SP@5g kg−1 (1:1.85) which proved to be good in the management of aphid.
