Although a fungus is technically a small plant, it cannot make its own food and therefore survives by being a parasite-living off other plant hosts. A common fungus, southern blight, affects many vegetables, including tomatoes and potatoes. It appears as a fuzzy white growth on the plants stem near soil level. When the plant is infected with the blight, it wilts and then dies. The fungus may spread to the soil, where it can survive for years.

When the plant is infected with the blight, it wilts and then dies. The fungus may spread to the soil, where it can survive for years. Because a fungus can survive for years in soil, the best way to control such a disease is to remove and destroy the infected plants, as well as six centimeters of soil around them. Avoid spreading disease by washing off your tools and your shoes when you go from an infected area to a healthy part of your garden. At the end of the gardening season, do a complete cleanup. You can also keep disease away by rotating crops. Crop rotation can be effective in preventing soil-borne disease, especially when the disease is caused by a fungus that likes specific plants. For example, the fungus that causes southern blight is attracted to tomatoes. Once this fungus is present, it will thrive in the soil from year to year, at
