Work experiments were designed to verify the efficacy of nine medicinal plant extracts against Meloidogyne incognita (root-knot nematode) infecting eggplant (Solanum melongena L.). The tested plants were, Turmeric (Curcuma longa L.), Ginger (Zingiber officinale Roscoe), Peganum (Peganum harmala L.), Thyme (Thymus vulgaris L.), Bitter Melon (Citrullus colocynthis L.), Artemisia (Artemisia absinthium L.), Alpinia (Alpinia officinarum Hance), Thuja (Thuja orientalis L.) and Capsicum (Capsicum annuum L.). Results showed that nematode population and eggplant growth parameters were affected when different plant extracts under different concentrations 1, 2 and 3% were applied. Examination of root system showed that egg-masses, galls and females affected markedly. The P. harmala at 3% gave the highest reduction with second stage juveniles (J2S)/250 cc soil, galls and egg-masses/root system comparing to other treatments applied and nematode alone. No phytotoxicity to eggplant plants appeared at used application rates.
