Ethephon (Proxy; Bayer) was mixed with common snow mold fungicides, Interface Stressgard and Mirage Stressgard (Bayer) or Instrata and Banner Maxx II (Syngenta), and applied at two winter timings of pre-snow cover and post-snow melt. This was done to evaluate the compatibility and safety of these mixtures on greens because preceding spring seedhead programs with winter ethephon applications has improved annual bluegrass seedhead suppression – and the timing coincides with fungicide applications for snow mold protection.
