Late Blight on a Tomato Leaf
Late blight is a disease that affects mainly tomatoes and potatoes. Once it takes hold, the spores spread rapidly and great distances. Cool, wet weather encourages the development of the disease.
Using certified seed potatoes will reduce the risk of late blight; if it manifests itself, it may be treated with appropriate fungicidal sprays.
