A total of 93 field pea crops were surveyed in Alberta for root rot and mycosphaerella blight. Root rot and mycosphaerella blight were present in all regions, and in 99% and 30% respectively of fields surveyed. Roots with symptoms of aphanomyces root rot were observed in all regions surveyed, but confirmation of the pathogen with PCR tests is ongoing. Root rot incidence and severity were lower in 2015 compared to 2014 for crops in east and west central Alberta.
