Fungi cause many of the diseases that impact tomato plants, however, there are also bacterial and viral diseases that can impact the growth of the plant. In order to prevent or reduce the number of diseases that impact the tomato plants, it is important for gardeners to understand the codes that relate to the disease resistance of the types of tomato plants that is available for seed purchase.
Each of these code utilize letters to indicate which diseases the tomato plant varieties is resistant to. By purchasing a variety of tomato plants that contain the correct letters associated with the diseases that are common in you growing region, the gardener can ensure that the tomato plants remain healthy and produce tomatoes.

Tomato disease codes and how to protect tomatoes
For instance, the letter V indicate that the tomato plant is resistant to Verticillium wilt, which is an disease that enters the plant through the roots and causes the leaves of the plant to turn yellow. The letter F indicates that the plant is resistant to Fusarium wilt, which affect the vascular system of the plant and causes the plant’s branches to wilt. The letter N indicates that the plant is resistant to root knot nematodes, which are organisms that live in the soil and create galls on the roots of the tomato plant.
The letter TM indicates that the plant is resistant to the Tobacco Mosaic Virus, which cause the leaves of the plant to become mottled and twisted. Additionally, there are codes for diseases that impact the leaves of the plant, such as codes for resistance to Alternaria stem canker, gray leaf spot, and leaf mold. Because some of these diseases are more aggressive then others, some seed packets may include letters to indicate resistance to diseases like Fusarium race 1 and Fusarium race 2.
Within the market for tomato plants, there are many different type of tomato plants that can be purchased. Each type of tomato plant has its own benefit and growing requirements, but there are also differences between each type of plant in relation to their disease resistance. For instance, hybrid tomato plants are often bred specifically to contain a high level of disease resistance, whereas heirloom tomato plants may contain superior flavor but often dont contain the same disease resistance as hybrid tom
Determinate tomato plants will grow to a certain size and all of their fruit will mature at once.

If you live in an area with high humidity, you should ensure that the tomato plants that you grow have resistance to blight, as blight love high humidity levels.
