Powdery mildew is first noticed on older leaves as a yellow spotted appearance, that upon closer inspection has a whitish-gray powder on the surface. The leaves will eventually die, but usually remain attached to the stem. The disease is worse under warm, dry conditions.

Sulfur dusts or wettable sulfur sprays are effective preventative controls. The established disease will require one of the labelled mildew fungicides.
