FMC Announces EPA Registration of New QuickSilver T&O Herbicide Uses

PHILADELPHIA, Pa. – FMC Corp. today announced that the Environmental Protection Agency has registered new uses on the label for QuickSilver® turf and ornamental herbicide. The revised label covers three new uses of QuickSilver:

1. For golf - on bentgrass putting greens and tees to control silvery thread moss, Bryum argenteum
2. To control broadleaf weeds 7 days after emergence of turfgrass in newly seeded, sodded or sprigged areas
3. To control broadleaf weeds on stone-covered yards. 

Previously of concern only in moist areas receiving low light intensity and mild climates, silvery thread moss is invading intensively managed putting greens in many areas of the United States. This may be due to the removal of mercury based fungicides, lower mowing heights, reduced nitrogen levels, over-irrigation, shade, and poor air circulation.  While some of these contributing factors may be managed, in order to maintain faster greens, chemical control measures, such as the use of QuickSilver T&O herbicide, may be necessary. 
 
The active ingredient in QuickSilver, carfentrazone-ethyl, makes it a powerful yet environmentally sensitive herbicide. FMC says the product does not impact birds or earthworms, and is unlikely to harm honeybees, or predators and parasites.
 
FMC also announced the availability of a new Best Management Practices (BMP) publication, describing the appropriate use of QuickSilver for this golf application. To obtain a copy of this BMP sheet, Silvery Thread (Bryum argenteum) Moss Control on Creeping Bentgrass (Agrostis palustris) Putting Greens and Tees With QuickSilver(R) T&O Herbicide, contact your local FMC representative, or call the FMC Customer Satisfaction Center at 800/321-1FMC, or visit http://www.pestsolutions.fmc.com/.
