Powdery Mildew-Resistant Tomato Cultivars

The following tomato varieties have been bred to be resistant to powdery mildew, a fungal disease that affects tomatoes and many other plants. The primary symptom is powdery white spots on the leaves that get progressively bigger. The disease usually begins on the lower branches and moves up. The fungus likes cool, humid conditions and is more likely to become a problem during cloudy weather. The best way to prevent the occurrence of this disease is by planting cultivars that are resistant to it. I've listed four tomato varieties here.
