Novel Resistances Provide New Avenues to Manage Alternaria Leaf Spot () in Canola (), Mustard (), and Other Brassicaceae Crops.

Alternaria leaf spot () can be a devastating disease in canola () and mustard (), but there are no highly effective host resistances available. Screening of 150 diverse Brassicaceae varieties under glasshouse conditions highlighted important novel resistances. In particular, '4076' and 'Wasabi Rocket' had complete resistance across disease assessment parameters (leaf incidence [%LDI]; severity [%LAD]; consequent defoliation [%LCI]).

Temperature Drives Contrasting Alternaria Leaf Spot Epidemic Development in Canola and Mustard Rape from and .

Recent surveys of canola () crops across southern Australia highlighted that Alternaria leaf spot on canola is not solely caused by but that other spp. are also involved, including . Studies were undertaken into the effects of different temperatures (14 and 10°C [day and night] or 22 and 17°C [day and night]) on development of Alternaria leaf spot caused by as compared with in cotyledons (embryonic leaves) and true leaves (first leaves) of canola ( 'Thunder TT') and mustard rape ( 'Dune').
