Plant pea fields further away from a previous crop of peas, as Ascochyta spores do travel by wind. Use a recommended seed treatment. These conditions favour growth of the disease mycelium. After the incubation period the trained analyst identifies the disease colony by its white mycelial growth which is generally full of brown or reddish brown pycnidia. The percentage of Ascochyta infection is reported on the Certificate of Analysis.
Lentils tend to have higher levels of Ascochyta infection than peas.
There is no legislated standard for Ascochyta infection levels.
