Mildew on Parsley and Lovage
I've been growing herbs for years and never had any disease problems until this year. My parsley and lovage plantings seem to have either powdery or downy mildew. The infection is pretty bad on both. I've searched the web for photos of what the mildews look like on each plant but not much is available. I sprayed them with a sulpher spray - no results. I am considering Greencure (potassium bicarb).
Anyone have any ideas??
