Talking Turf: Bayer Green Solutions Team Helps You Plan Now to Maximize Snow Mold Control

Published online: Aug 15, 2017 Sod

It’s time to start planning snow mold applications. Here are quick points on maximizing control of snow molds.

* Check calibration and spray coverage – A full season of applications may wear out or plug nozzles and the impact won’t be visible until next season.

* Consider an early application – While snow mold symptoms typically appear in the spring following snow melt, sclerotia begin to germinate in the fall at air temperatures of 50-65°F. Controlling the first stages of disease development with a fungicide application will help limit snow mold severity in the spring. 

* Protect young turf – Fall-seeded turf is usually heavily fertilized to hasten establishment, but this also makes it succulent and especially susceptible to snow mold in the late fall. Be extra cautious with young turf and protect it with preventative snow mold applications.

* Protect compromised turf – Shaded areas, compacted clean-up and traffic areas, under-fertilized, and otherwise somewhat compromised areas may be more susceptible to snow molds.

* Use multiple active ingredients – Two or more active ingredients in a fungicide application consistently provide better snow mold control than applications with only a single active ingredient.

* Consider reapplying after heavy rain  If two or more inches of rain falls between the final fungicide application and snow cover, consider making an additional application to maximize disease control and ensure a successful start to the 2018 season.

* 2017 Bayer solutions – Use combinations of Interface Stressgard, Mirage Stressgard and/or Tartan Stressgard, which provide effective control of snow molds.
