Buckeye rot

Buckeye rot or Fruit rot is caused by the water-moulds Phytophthora capsici, Phytophthora drechsleri and Phytophthora parasitica.

Symptoms
Brown concentric rings around a grey spot on unripe fruit can be seen. Spores are splashed from soil onto fruit.

Treatment
None. Remove and destroy affected fruit.

Prevention
Tie lower trusses up out of splash distance. Apply a peat mulch and water carefully once fruit is forming.
