FAQ
Frequently Asked Questions
No, spur blight is a plant disease and poses no direct risk to human health. It only affects the vitality and fruit production of the plant.
The fungus Didymella applanata is specific to plants in the Rubus genus (like raspberries and blackberries). It will not spread to unrelated plants like vegetables or flowers.
Spur blight specifically affects the fruiting buds (spurs) and surrounding tissue, often starting as small lesions. Cane blight (caused by a different fungus) typically causes larger, darker cankers that girdle the entire cane, often entering through wounds. Both are serious diseases of brambles.
Look for purplish-brown, oval-shaped spots or lesions on the young green cane, often centred around a leaf or bud stem (node). As it develops, the lesions may turn greyish with black specks (fungal fruiting bodies), and the affected bud may die.
