Anthracnose of Lupins and Tomatoes Colletotrichum gloeosporioides
Description:
A fungus that attacks a wide range of species and is particularly significant in affecting the ripening fruit of Tomatoes. In Tomatoes small round water soaked and slightly depressed spots appear that develop into sunken, light brown depressions about 12 mm diameter with concentric rings of darker fungal fruiting bodies. These can be dense enough to turn the centre of the lesion black. In warm humid conditions the whole fruit may be rotted.
Species Affected:
Lupins especially White Lupins (Lupinus albus), Tomatoes.
Biology:
Favoured by temperatures around 250C and high humidity.
The disease may be carried on the seed.
Diseased fruit on or in the soil can infect new plants.
