Three plant materials: two synthetic botanical materials, camphour and citric acid and one fixed oil; castor been oil were formulated as concentrated emulsion: (EO) for castor and EW for camphor except citric acid formulated as soluble liquid (SL) formulation. Toxicity of the prepared formulations was determined against aphid, Aphis craccivora (Koch) using slide -dip technique and their Pesticidal efficiency was determined against sucking pierce pest infested bean plants, which was: Aphids Aphis craccivora according to Ministry of Agriculture protocol but under small scale.
Results of the tested formulations against aphid, A. craccivora indicated that all the tested formulation showed suitable toxicity against aphid as indicated by LC50's values; Citric acid showed the highest toxicity against aphids followed by camphour, and castor oil.
Semi-field experiment indicated that fixed oil, castor oil; synthetic botanical materials; camphor and citric acid at concentration 2% (v./v.) showed successful results against sucking-pierce pest: aphid A. craccivora as showed suitable initial and residual effects at this concentration according to Ministry of Agriculture Recommendation.
