Propiconazole 14.3 can be used on certain ornamentals to control powdery mildew and leaf spot on certain ornamentals however we would need to know what type of plants, shrubs, etc in order to provide you with a mix rate. Please use the list of Ornamentals of page 7 of the product label for the proper mix rate. The product label does advise not to apply to African violets, begonias, Boston fern, or geraniums. The mix rates are under Table 3 depending on the ornamental type and disease.
