Curly top virus on tomatoes
A viral disease that attacks vegetable crops such as tomatoes. To prevent, control the aphids that spread the disease. Use shiny material such as silver Mylar under plants. Drench soil with natural organic products. Spray plants with 3% hydrogen peroxide - it really works but can burn plants during hot weather. Spray during the coolest part of the day. A quality commercial product is PureGro Disease Stop.
