Pest of the month: Anthracnose
Month: November
Fungus: Anthracnose – Colletotrichum spp.
Importance: Common nursery pathogen
Symptoms: Symptoms vary with host, but spots often initially appear as small water-soaked circular lesions on leaves, stems or fruit. With time, spots enlarge and become tan to dark brown or black in colour. Sometimes leaf spots may be surrounded by a bright yellow halo. Lesions may become sunken and produce concentric bands of tiny black fruiting bodies on the dead tissue in the centre of spots. Salmon-coloured spore masses may exude from fruiting bodies under conditions of high humidity. More
