Tomato late blight is a rapidly spreading fungal disease that can ruin a tomato or potato crop. This is the disease responsible for the Irish Potato Famine.

It occurs later in the tomato growing season than early blight and mainly during cool, wet weather. Greasy gray spots will appear on the tomato skin and leaves. Portions of the stems will turn black. The gray spots will eventually dry up and become papery.


Late Tomato Blight Solutions

Late blight tomato disease can overwinter in zones 10 and 11. It can survive inside seed potatoes in colder zones.

If blight has been a problem in your area during the previous growing season, remove all potato plant parts from the soil at the end of the season. Do not compost any of it, bag it and place it in the trash. Do not save seed potatoes.

To control late blight on tomato plants, spray them with a copper fungicide every 7-10 days. This is not a cure for blight but it will slow the progression of the disease.

  • Mulch is the best way to treat soil for blight. It will keep the plants cooler and less stressed. But, more importantly, it will prevent contaminated soil from splashing up onto the lower leaves and stems of the tomato plants.
  • Pruning tomato plants and growing them on a tomato support like a cage or trellis will keep the foliage up off the ground.
  • Use drip irrigation when watering tomatoes to prevent splashing.
  • Do not save seed from infected plants.
  • You will likely have a bigger problem with tomato plant blight when growing heirloom tomatoes . The newer tomato varieties are more resistant.
