Key Messages

• The new faba bean cultivar, PBA Amberley, is provisionally rated MR to chocolate spot (CS). Additional field trials are required to determine whether foliar fungicides are needed to control CS in this variety.
• A foliar spray of tebuconazole at grass spray timing is still the most effective way to control cercospora leaf spot on faba bean. Uniform® in-furrow and Systiva® as a seed treatment were included in the trial but only had a small or no effect on controlling this disease.
