Assessment of ascochyta blight on faba bean

Assessment of ascochyta blight (Ascochyta fabae) on faba bean

This protocol presents a sampling and an assessment method to assess the ascochyta blight development on leaves and pods in field experiments on faba bean. A disease scale is given for the calculation of a disease index on pods and leaves.


This protocol could be used for instance to distinguish cultivars according to their resistance to ascochyta blight.
