POWDERY MILDEW Rotation Program Powdery mildew can affect a wide range of herbaceous and woody ornamental crops. Knowing which crops are susceptible, coupled with good scouting and a preventive rotation of effective fungicides, can allow you to avoid the unsightly effects of powdery mildew on your plants. The following recommendations help reduce the risk of disease in your operation.
Powdery mildew fungi form white, talcum-like spots called Environmental Conditions Conducive “colonies” on leaves, stems and flowers. Over time, these colonies to Powdery Mildew increase in size and number to cover the plant’s surface. If not controlled, severe infections will cause leaves to turn yellow, brown Powdery mildews are most likely to develop in the spring and then drop, resulting in reduced plant vigor and growth. While or fall when: powdery mildew is often first observed on the upper surface of the • Temperatures are between 62° - 72°F leaves, both sides may develop colonies, so it is important to check • Relative humidity levels are 70 percent or greater both sides of the leaf when scouting. • There is reduced light intensity Moisture on plants from dew or irrigation does not favor the Symptoms development of powdery mildew and can even limit the disease • White powdery spots or coating on both sides of leaves, stems development by inhibiting germination and killing the spores. and young buds • Flower petals and bracts of poinsettia can also be affected Cultural Tips • Yellow or brown leaves • Provide a clean, dry • Keep humidity low • Distorted leaves and flower buds or undeveloped flowers growing environment by heating and venting • Stunted growth • Check incoming plants as needed for disease • Remove diseased plants Powdery mildew can be more serious on woody ornamentals like • Scout fully expanded immediately to limit spore roses and crape myrtles because it attacks new growth including leaves weekly, particularly in production and spread buds, shoots, flowers and leaves. the lower to mid-canopy • Overhead irrigation may where air movement may reduce the spread of powdery be limited mildew as it washes the spores off plants
Susceptible Crops Several different fungi cause powdery mildew and each prefer different plants. The fungi listed below favor the corresponding plant types.
Erysiphe cichoracearum is a common powdery mildew fungus Fungi Susceptible Crop that can infect many plants, including: Erysiphe australiana Crape Myrtle Erysiphe polygoni Hydrangea • Ageratum • Delphinium • Rudbeckia Microsphaera penicillata Lilac • Aster • Gaillardia • Salvia Oidium sp. Snapdragon, Poinsettia • Calendula • Gerbera • Scabiosa Oidium begoniae Begonia (fibrous and tuberous) Oidium longipes/Erysiphe sp. Petunia • Coreopsis • Gloxinia • Verbena Sphaerotheca pannosa var. rosae Rose • Dahlia • Phlox • Zinnia Sphaerotheca macularis Pansy
