Tomato Diseases: Soil Rot (Rhizoctonia solani )
Tomato Diseases: Soil Rot
This disease can attack your tomato plants no matter where you have your garden. It is caused by the same organism that causes damping-off. The first symptom is a brown, slightly sunken spot on the fruit, with sharply outlined (not smooth) concentric markings close together. It enlarges and often breaks open.
Soil rot can invade either through wounds in the tomato or through uninjured skin. It usually occurs during wet periods and on moist soils where plants cover the ground; or when the fruit has been splashed by rain. Avoid poorly drained soil, use a good mulch, and use varieties of tomatoes suitable for staking.
