PCNB, the active ingredient in Turfcide® 400, is a multi-site contact fungicide with a unique mode of action that has been used for snow mold control for over 50 years, and for good reason. PCNB is widely recognized as the most effective single active ingredient for control of all three major snow mold pathogens, Microdochium nivale (pink snow mold/Microdochium patch), Typhula incarnata (gray snow mold) and Typhula ishikariensis (speckled snow mold).
Historically, PCNB has been used as a stand-alone fungicide treatment for snow mold control at application rates of 12 – 16 fl. oz./1,000 sq. ft. More recently, snow mold treatments have evolved to include mixtures of two or more active ingredients that usually include both systemic and contact fungicides.
Today, chlorothalonil is a commonly used contact fungicide in mixtures for snow mold control. Yet, PCNB consistently outperforms chlorothalonil in snow mold field trials, when evaluating PCNB and chlorothalonil as stand-alone treatments or when comparing them as differing components in otherwise identical fungicide mixtures.
Use Turfcide 400, powered by PCNB, as the contact fungicide component in your snow mold program this fall. You will get substantially better protection from Turfcide 400 than from chlorothalonil against all three major snow mold pathogens. Chlorothalonil is good for dollar spot. Turfcide 400 is better for snow mold.
