Columbia County Pennsylvania
Thank you for your question. Early blight is one of the most common tomato diseases. To prevent it, you should purchase seeds or plants resistant to blight. Do not plant tomatoes or related crops like potatoes in the same place for at least two years. Avoid overhead irrigation or sprinkler systems which create a humid environment favorable for the disease. Mulch your plants to help keep leaves dry. Stake them to improve air circulation. Fertilize properly: do not over-fertilize with potassium; maintain adequate levels of both nitrogen and phosphorus. If your plant becomes infected remove and discard infected leaves as you see them. In the fall remove or bury infected plants. Use fungicides when appropriate, but timing is important and you should follow the label instructions carefully. Call your local Extension Office for information about appropriate fungicides. Please let me know if you need any additional information or have any questions.
