A field experiment was conducted to evaluate the bio-efficacy of six different insecticides against
safflower aphids ( Theobald). Dimethoate (0.03%) and imidacloprid (0.004%) were
most effective against safflower aphids; however, thiomethoxam (0.005%) followed by acetamiprid (0.004%),
profenofos (0.05%) and acephate (0.03%) were also effective against the safflower aphids. Highest yield of
safflower was observed from plots treated with dimethoate (0.03%); but, the maximum incremental cost-benefit
ratio was recorded for imidacloprid (0.004%) followed by dimethoate (0.03%).
