Sour odor is evident
Rot begins at stem scar followed by whitish fungal growth; can occur on mature green and ripe tomatoes;The sour-rot pathogen, Geotrichum candidum, is a type of yeast. Its growth on lesions on fruit resembles a thick, gelatinous mass similar in appearance to cottage cheese. The lesions themselves may initially be watery but later become coated with pathogen growth and remain relatively firm unless a secondary infection by a soft rot bacterium occurs. However, the odor of these lesions is similar to that produced by lactic acid bacteria, hence the disease name, sour rot.
