  • Potato is an important crop in Mediterranean climates where it can be grown all year round along the coast. The cyst nematodes, Globodera rostochiensis and G. pallida are the most noxious nematodes of potato, with damage and nematode reproduction being more on spring than on late summer or autumn planted crops. Severe tuber infestations by G. pallida have been observed on spring and late summer crops. During the last two decades these nematodes have spread in new areas and the use of resistant cultivars seems to have caused a shift in the nematode species and pathotypes. The most infested areas appear those where non certified potato seed tubers are cultivated in late summer and where potato is cultivated every or every other year. Damage by root knot nematodes Meloidogyne incognita and M. javanica occurs on crops planted late in summer especially in sandy soils after a summer crop susceptible to the nematodes. Control of cyst nematodes is mainly by crop rotation but nematicides and soil solarization are effective. Many cultivars resistant to pathotype Ro1 of G. rostochiensis have been introduced and are cultivated independently of the presence of the nematodes. Usually, no measure is taken to control root-knot nematodes. Screenings of breeding material identified clones of cultivated and wild Solanum spp. resistant to cyst and root-knot nematodes. Interestingly an advanced clone of S. tuberosum was resistant to Ro2 of G. rostochiensis, race 2 of M. arenaria, M. hapla, race 1 and 2 of M. incognita and M. javanica. (literal)
