To assess (1) yield loss from disease infection in lentil and, (2) economics of disease management control strategies
Botrytis grey mould and ascochyta blight in lentil were infrequently reported in SA in 2023. No disease infection occurred in lentil at Riverton in 2023. July conditions were conductive to disease progression. However, canopy closure was not reached until late August, followed by a dry spring, slowing any disease progression. For this reason, there was no yield response to fungicides applied to control disease (P=0.195). There was a grain yield response to variety (P=0.011, LSD=0.2566), with PBA Jumbo2 (3.74 t/ha) yielding more than PBA Highland XT and PBA Bolt (3.41 t/ha and 3.37 t/ha, respectively).
