Designed for selective postemergence control of silvery thread moss (Bryum argenteum) on golf course greens and tees. Ideal for maintaining moss-free, high-quality playing surfaces. Safe for use on most creeping bentgrass varieties and annual bluegrass. Research has shown QuickSilver™ herbicide reduces up to 90% of moss in just two applications when used at labeled rates according to label directions.

QuickSilver rapidly penetrates into plant cells for fast-acting control. Effective under both cool and warm environmental conditions combined with minimal risk of damage to desirable turfgrass species. When it comes to silvery thread moss control, nothing works quite like QuickSilver. QuickSilver can control silvery thread moss in just two applications and is effective in both cool and warm temperatures, ensuring year-round moss control as needed. QuickSilver, with the active ingredient carfentrazone, works by effectively inhibiting a key enzyme in moss chlorophyll production and is formulated to be gentle on turf.

Key Benefits

• Fast-acting control: Visible symptoms in as little as 24 hours
• Rainfast: Within one hour
• Selective and turf-safe: Controls moss while preserving turfgrass health
• No residual activity: Allows reseeding or overseeding within one day
• Works in various climates: Effective in both cool and warm weather conditions

• Application Rate: 4.9 mL/100 m2 per application
• Maximum per year of 19.6 mL (44 grams a.i. per 100 m2)
• Minimum application rate is 1.46mL/100 m2
• Minimum retreatment interval is two weeks
• Control Over Longer Periods: If necessary applications may be repeated every two weeks at a rate no less than 146mL/ha
• Adjuvants: Use of a nonionic surfactant at a rate of 0.25% volume/volume
• Application Method: Use a spray system ensuring thorough and uniform coverage. Avoid spray drift onto non-target plants
• Spray Volume: Apply using 748-935 L/ha to maximize coverage, especially in dense moss populations
• Tank Mixing: Ensure spray equipment is clean before use. Mix with water and maintain continuous agitation
• Turfgrass Safety: QuickSilver is safe on most creeping bentgrass varieties
• It is recommended to make a test application before use. Some varieties have not been tested. Penncross and Crenshaw are safe — no need to test
• Restrictions: Not for aerial application or irrigation system application

QuickSilver allows for fast reestablishment of bentgrass, enabling quick replanting to break the moss opportunity cycle
