The fungicides for Sclerotium rolfsii control are not available for homeowners to purchase at retail centers . These organisms may affect stems , leaves , bud scales , and flower petals . Since the beetles are strong flyers and can readily move into the garden ; continual vigilance throughout July may be necessary . Sclerotia produced by white mold are brown-black , resemble rodent droppings , and are usually found on the inner stem of infected plants . Several fungal organisms are capable of causing spots of varying sizes and colors on peony . All of these disease organisms will cause iris leaf tips to brown and iris plants to senesce , mimicking symptoms caused by iris borer . ‘ Liberty , ’ ‘ Redfree , ’ and ‘ William ’ s Pride ’ are all scab resistant .
