Summary, etc. <p>An experiment was conducted in field during 2017-18 for efficiency evaluation of seven indigenous products along with a check (imidacloprid 17.8 SL at 20g <em>a.i</em>/ha) to manage <em>Aphis craccivora</em> Koch on cowpea. In the bio-efficacy study, leaf extract of <em>Polygonum hydropiper </em>at 5% was found to be most effective and efficient in aphid population reduction (up to 77.48%), followed by neem oil at 1% (74.11%), <em>Ocimum sanctum</em> leaf extract at 5% (74.00%), <em>Murraya koenigii</em> leaf extract at 5% (70.96%), ash at 10 kg/ha (68.04%), river sand + neem leaf powder at 10 kg/ha (3:1 ratio) (44.48%) and ash + river sand at 10 kg/ha (5:1 ratio) (42.53%) after 7 days of spraying.</p>
