Several waxes and plastic polymers were evaluated as protectants from foliar pathogens on maize (Zea mays), sorghum (Sorghum bicolor), and wheat (Triticum aestivum). These products reduced anthracnose, leaf blight, rust, downy mildew, and powdery mildew in varying amounts. The potential of these products for disease control is reviewed and discussed.
