Host: Lycopersicum esculentum Mill. (tomato)Disease name: Sour rotPathogen name: Geotrichum candidum Link
Sour rot is a common decay of tomatoes everywhere they are cultivated, especially when temperatures are above 30°C. The decay can start in cracks, cuts, or insect bites in the skin of the fruit or at the brim of the scar of the stem. The disease develops rapidly, and the affected tissues become soft and watery. The skin in the affected area cracks, and a white, gaseous scum with a sour smell forms. At this stage, there is a proliferation of fruit flies, Drosophila melanogaster, which distribute spores and fragments of mycelium to other fruit with lesions of the skin. Sour rot can be diminished with careful management from the field to the shelf.
