Pulse School: Diseases, Root Rots and Wet Conditions

Ample moisture availability, combined with the price incentive to move to tighter pulse crop rotations, has resulted in high disease pressure for many of this year’s pea and lentil acres.

In this episode of the Pulse School, Allison Friesen joins Kelvin Heppner for an overview of which diseases to look for in peas and lentils, fungicide timing and the impact of root rot:
