Surfactants, pigments, and PGRs are all valuable tank-mix partners for snow mold sprays. Keep reading to learn more about the benefits they can add to your fall applications.


Surfactants can improve the efficacy of snow mold fungicides. For example, Sync is a fungicide activator that enhances the performance and longevity of contact and systemic fungicides, even when applied at reduced spray volumes. Surfactants also help prevent desiccation in the case of a winter without snow coverage.


Pigments make valuable tank-mix partners for multiple reasons. In addition to improving turf appearance, the color from a pigment like Optimizer Green Shade can help warm the ground and promote darker green turf in the spring. Pigments also serve as spray pattern indicators to promote uniform coverage of your snow mold spray. 


Plant growth regulators are another useful tank-mix partner for preventative snow mold spray. Products like PGR 113 MC can prolong the performance of snow mold fungicides by controlling plant growth, which is especially helpful in the case of a warm winter. PGRs applied in the fall can also help control weed pressure in the spring. For example, Proxy suppresses Poa annua seedheads and makes a good tank-mix partner for snow mold sprays.

Not knowing what kind of winter you’ll have, you can only do your best to prepare for whatever the season brings. Adding tank-mix partners to your fall snow mold sprays is an excellent way to do that. As always, read labels before mixing products. And talk to your ATS rep about which of the above tank-mix partners may benefit your course.
