The efficacy of cypermethrin, deltamethrin, dimethoate and malathion was determined against Aphis craccivora on green gram [Vigna radiata] in Assam, India, during 1993-94. The yield was significantly increased by all the insecticide treatments, except malathion, with a maximum yield of 1.16 t/ha for 0.028% deltamethrin.
