"If you've got it severe enough it can be devastating and if not it can be managed... it just depends on where you are and what weather conditions you've had in the past and the amount of peas or lentils you've grown on those fields before."
"Aphanomyces pressure is often highest in wetter parts of fields, such as low areas or along waterways where moisture persists. The disease can also appear alongside other root pathogens, further weakening plants and increasing the risk of yield loss."
"Crop rotation remains one of the most effective tools for managing the disease. On his own farm, Auch typically spaces pulses about five years apart in the rotation, though some recommendations suggest even longer intervals."
Aphanomyces root rot significantly impacts peas and lentils, with severity varying by location, field conditions, and crop history. The disease concentrates in wetter field areas and low-lying zones where moisture persists, often appearing alongside other root pathogens that compound plant stress and yield losses. Crop rotation remains the most effective management strategy, with five-year intervals between pulse crops recommended, though longer spacing may be necessary in some cases. Alternative pulse crops like faba beans or chickpeas offer additional rotation options. Despite root disease risks, pulses provide substantial agronomic benefits including yield advantages for subsequent crops. Management requires diverse crop rotation, careful field monitoring, and practical profitability considerations.
