A survey of indoor cucumbers in the Tripoli region conducted during February–March 1980 revealed that root-knot nematode (Meloidogyne incognita) was inflicting heavy loses in most areas. Most of the plastic tunnels were heavily infested. The disease ranged from mild to severe. In some tunnels this led to total crop failure. Glasshouses were free from infestation where soil was fumigated prior to cultivation.
