Abstract

The management of the root-knot nematode, Meloidogyne incognitainfecting cucumber(Cucumis sativus) roots, using the nematicidal activity of chopped fresh leaves as soil amendments such as; Metricaria chamomilla, Olea europaea, Citrus sinensis, Punica granatum, Musa paradisiaca, Datura metal, Eucalyptus globulus, Ricinus communisandFicus benjamina under organic farm conditions was studied. The chopped fresh leaves of the tested plants were incorporated into the soil at the rate of 100 g/plant. Eucalyptus globulusgave the highest reduction of Meloidogynespp. juveniles in soil as well as galls, females and egg-masses in roots since their values averaged 94.54%, 95.04%, 96.38% and 98.00%, respectively,followed by Metricaria chamomilla after 45 days post treatment.Eucalyptus globulus still gave the most reduction and diminishing nematode numbers after 90 days.Olea europaeaand Punica granatumranked statistically in the second and third categories, respectively in number of soil juveniles.All treatments significantly improved infected cucumber growth criteria.
