Laboratory tests were conducted to assess the insecticidal activity of Alum salt and its formulation, A1 (Alum+ Tween) and A2 (Alum +sodium dodecyl sulphate {SDS}) against Aphis craccivora stages under laboratory condition. The insecticidal effect of Alum was noticed as slight affect at 2, 4, and 6 hours of treatments in case of nymphs, adults and winged stage respectively where as it increased gradually to record the highest activity after 12 hours. Soluble powder formulations of Alum were more effective than Alum alone. This indication was noticed as increasing in effectiveness without any changes in behavior of activity. The effectiveness of formulated Alum soluble powder was affected by the type of wetting agent that used in formulated preparations. A2 formulation (Alum +SDS) was more effective than A1 formulation (Alum +Tween) against all stages at all exposure periods.
