QuickSilver® T&O Post-Emergent Herbicide by Envu is a selective contact herbicide designed to control silvery thread moss in turfgrass environments. Ideal for golf courses, sports turf, and ornamental lawns, QuickSilver acts fast and is rainfast within just one hour. The product is especially effective on creeping bentgrass and Bermudagrass greens and tees, providing moss control without damaging desirable turf species. Research has shown that QuickSilver can eliminate up to 90% of moss in as few as two applications spaced 14 days apart.
