Many gardeners have been puzzled by the sudden wilting and death of tomato plants. Possible causes of wilting include lack of water, vascular wilts, tomato spotted wilt virus, walnut toxicity, or stalk borers. Tomato plants require approximately 1 inch of water per week.
What causes tomato plant leaves to turn yellow? Yellow leaves that have purple, distorted veins are a sign that psyllids have infested the tomato plant. Treatment involves looking on the bottom of leaves for insects, removing them and applying a pesticide to the growing area. Tomato plants that stop growing and turn yellow all over may have the curly top virus. The beet leafhopper transmits this disease by jumping from plant to plant.
