Damage Symptoms

White, shiny, blistered tissue develops on portion of fruit suddenly exposed to sun. The lesion often becomes sunken and wrinkled. Mature green and breaker tomatoes are most susceptible.


Conditions for Development

Fruits become suddenly exposed to direct sunlight. Such exposure is often due to pruning or harvesting operations, or foliar disease.


Control

Be careful when pruning or harvesting so as to minimize exposure of fruits to direct sunlight. Use trellising methods that protect fruit from sunlight. Fungicide spray programs will protect foliage from disease infection. Use cultivars that provide good foliage cover.
