Target Crops: Potatoes & Tomatoes.
Challenges
Tomato or potato plants that have lost their leaves to late blight are poor producers. When tomato plants survive and go on to produce fruits, the fruits often have leathery patches that do not ripen properly. If not dug up early, blight spreads to potato tubers causing red-brown decay which will eventually rot and prevent them storing well.
Prevention
Avoid watering from above: Using soaker hoses or drip irrigation keep foliage dry, which makes it more difficult for late blight and other diseases to spread. Avoid overhead watering techniques (sprinklers).
