Tomato blight, in its different forms, is a disease that attacks a plant’s foliage, stems, and even fruit.

Early blight (one form of tomato blight) is caused by a fungus, Alternaria solani, which over-winters in the soil and infected plants. Affected plants underproduce. Leaves may drop, leaving fruit open to sunscald.

Plus, it’s ugly!

Take these precautions to keep early blight at bay in your tomato plants.

  • Plant tomatoes in a raised bed to improve drainage and provide better air circulation. Extra space lets air move around plants and lets leaves dry quicker.
  • Treat plants organically with copper spray to slow onset. Apply on a regular schedule, once a week and after rain.
  • Control symptoms with a biofungicide. Once blight is present and progresses, it becomes more resistant, but you can lessen and slow symptoms with a biofungicide like Serenade. Treat it as soon as possible and on a schedule.
