Abstract
In the early 1990s, powdery mildew became a recurring problem on chili peppers and bell peppers in all production districts in California. Growers were initially unprepared to deal with the disease. Research has shown that several fungicides can control this disease. Sulfur is most effective as a preventive fungicide. In variety trials, four experimental varieties were significantly less susceptible to powdery mildew than the standard commercial variety. Genetic resistance is likely to eventually be incorporated into commercial bell pepper varieties.
