Mansour, A.M.A.
The field experiment was carried out in a turfgrass farm located at Menofia Governorate during 2006 year. Six insecticides and three mineral oils were evaluated for their efficacy as aphicides on wheat aphid insect, Schizaphis graminum (Rondani) infesting Seashore paspalum, cv Sea Dwarf turfgrass. All treatments gave satisfactory results, whereas Malathion 57% EC, Reldan 40% EC, Deltan 40% EC and Sumithion 50% EC gave highly superior effect. The residual toxicity of these insecticides were 97.7, 97.7, 97.4 and 92.4%, respectively. Folk oil 2% EC gave the least aphicidal effect with a residual toxicity of 63.68%.
