Powdery mildew is a widespread fungus that is carried by the wind. It multiplies rapidly in high humidity so thrives in overcrowded garden beds where the
air circulation is poor. Identify it by the characteristic grey-white, powder-like mildew on infected leaves. Affected foliage withers, become distorted
and dies.
To control its spread start by choosing disease-resistant cultivars, avoid overcrowding plants in shady areas of the garden, don’t use overhead irrigation
late in the afternoon, and keep the area clean of plant debris that may carry the spores. Also try Yates Fungus Gun or OCP’s Eco-fungicide.
