Phoma stem canker (blackleg) of oilseed rape (canola) and other Brassica crops [PDF]

open access: yes
Phoma stem canker (blackleg) of oilseed rape, Brassicas and radish is caused by two closely-related fungi, Plenodomus lingam and P. biglobosus (formerly Leptosphaeria maculans and L. biglobosa). Plenodomus lingam is more aggressive but P. biglobosus can

Temporal dynamics of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine interspecific competition and disease development on oilseed rape

open access: yesPest Management Science, EarlyView.
This study provides evidence that the timing of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine the outcome of interspecific competition and disease development on their host oilseed rape. Abstract BACKGROUND Phoma stem canker is one of the most economically damaging diseases of oilseed rape, caused by co‐existing fungal ...
