A survey of incidence and severity of
Ascochyta
diseases on peas in Morocco was carried out in 1992. All the three Ascochyta species of peas are found in the country. Their incidence and severity were higher on the green peas than on the dry peas. This is mainly due to the dry conditions prevailing during the dry pea growing season.
Ascochyta pisi
Lib. was isolated only from leaves and stem,
Mycosphaerella pinodes
(Berk. and Blot) Vestergr. more frequently from the leaves and stem than from the foot region, and
Phoma medicagini var.
pinodella
(Jones) Boerema mainly from the foot region
