Organocide Plant Doctor is a  fungicide that prevents and cures diseases like root rot, downy mildew, fire blight, and black spot by moving throughout the entire plant, protecting both the leaves and roots.
 
Staggs Garden Center recommends it because its unique dual action works as both a preventative disease treatment and a nutritional boost (containing Potassium and Phosphorous), helping gardeners stop current infections while simultaneously increasing plant metabolism, vigor, and yield.
