The efficacy of insecticides extracted from two different plants such as Allium sativum L. (Amaryllidaceae) and Capsicum annuum L. (Solanaceae) was tested as alternative insecticides.The effect of insecticides obtained from ethanol extraction from three plants was investigated using M. persicae . For bioassays two different methods were used with different concentrations. Experiments were conducted using 3 cm diameter leaf disk from untreated radish [ Raphanus sativus L. (Brassicaceae)]. The effects of four concentrations of extract were studied. All of experiments were repeated 10 times. As a result of the investigation, in leaf dipping method; the extract of C. annum the highest concentration showed the highest mortality in nymph and adult stages. The mortality of nymphs and adults at the same concentrations were 88% and 88% respectively. The mortality of adults at the same concentration of A. sativum 12% was 84% and 83% respectively. For the spraying method, mortality of adults at the same concentration of 12% was 82% and 86% respectively.}, number={4}, publisher={TARIM VE ORMAN BAKANLIĞI EĞİTİM VE YAYIN DAİRESİ BAŞKANLIĞI}
