Doktor Doom Fungicide, 500-mL

Doktor Doom Fungicide controls powdery mildew and other plant diseases thanks to its low concentrations of copper. When used as directed, this fungicide decomposes into forms that plants and microbes can use, meaning you don't need to worry about applying it right up to the day before harvesting your crops. Applied at the first sign of disease, this biodegradable fungicide helps protect your plants from infections that could stunt their growth and impact yield.
