Pea and Lentil Disease Update

Scouting of peas and lentils in Burke, Williams, Divide, Mountrail and McKenzie Counties for foliar disease continues as earlier planted crops start to come off the field (Adam Carlson, Crop Scout NDSU). In pea, ascochyta blight is commonplace in fields, with the highest incidence found in Mountrail County, but severity levels remain low as they have for most of the season (Fig 1). We are beginning to see white mold in some fields in Williams and Divide Counties, and powdery mildew has been observed in McKenzie County (Fig 1). Bacterial blight has been identified in all pea fields scouted (Fig 1).                                                                                                                                                                                     In lentils, ascochyta blight and anthracnose were almost universally present in Divide, Williams and McKenzie Counties but severity levels were low (Fig 2).
