Root lesion and stem nematodes associated with faba bean in North Africa

A. Troccoli, M. Di Vito


A survey of root lesion nematodes associated with faba bean was undertaken in 1999 in Algeria, Morocco and Tunisia. Pratylenchlls penetrans and Zygotylenchus guevarai occurred in each of the countries. Pratylenchus tharnei was common in Morocco and Tunisia. Pratylenchus neglectus and P. pinguicaudatus were found in Algeria and Tunisia, respectively, the last being a new record for that country. Several stem and leaf samples of faba bean were heavily infested by the stem nematode Ditylenchus dipsaci, often associated with tissue necrosis and distortions.
