Fall roses; fungal diseases

Warm days, cool nights and dew in the morning means ideal conditions for fungi to make roses ugly!

Powdery mildew attacks new growth and the stems of buds.

The first sign of powdery mildew infection is curling up of leaflets. The fungi enter the leaflet on the under side.

Another fungal disease, black spot, usually starts at the bottom of a rose, then defoliates the plant if not stopped. Prevention is easier than cure with fungal diseases.
