Firm round lesions, slightly sunken, initially orange or tan in colour. These lesions turn brown, then black with age and produce salmon-coloured spore masses. Used with permission from Univ.
Spores can also spread by movement of workers, animals and equipment.
Warm, humid weather, splashing rain, plasticulture. Do not plant strawberries after strawberries. Fungicides registered for use on strawberries do not provide adequate control of this disease. The lesions have no distinct border. They produce powdery spores that are easily airborne.
