The tomato is an easy-to-grow, low-maintenance crop that presents few challenges to home gardeners. Although tomato plants are hardy, they are susceptible to a variety of diseases. Fusarium wilt, verticillium wilt and tobacco mosaic virus are common diseases that cause major damage to tomato plants. When purchasing tomato plants, check the plants' identification tag for letters indicating that the plant you're buying is a disease-resistant variety of tomato.
