Symptoms:
Numerous fungi cause fruit rots on tomato. Lesions are water-soaked, and may have a white scummy growth in the cracks. Lesions often occur near the stem end scar.

Control:
Fruit should be kept off the soil (if possible), and surface wetting should be minimized. Furrow or drip irrigation is preferred over sprinkler irrigation. Preventative fungicide sprays may be required if a “zero tolerance” for defects production system is needed.
