What is moss on putting greens?
Moss infestations on creeping bentgrass ( Agrostis stoloniferia L.) putting greens have become an increasing problem. Demand from golfers for a more competitive playing surface, coupled with the restriction of mercury-based pesticides, has made bentgrass putting greens ideal habitats for moss (Burnell et al., 2004; Hummel 1994). Bryum argenteum (Hedw.) (Silvery-thread moss) is a common moss species found on creeping bentgrass putting greens, however, other species such as Byrum lisae, Amblystegium trichopodium and Brachythecium spp. have also been identified on bentgrass putting greens (Happ 1998). Mosses are a member of the Phylum Bryophyta. They are able to reproduce sexually via spores or from displaced fragments (Nelson 2007; Boesch and Mitkowski 2005; Yelverton 2005). They lack vascular systems and can absorb water and minerals throughout the entire plant (Boesch and Mitkowski 2005). This lack of a vascular system prevents systemic herbicides from translocating throughout the plant, making them useless for control (Yelverton 2005).
What herbicides kill moss on bentgrass?
Quicksilver (carfentrazone) is a member of the aryl triazolinone family of herbicides and is labeled for the control of Bryum argenteum (Hedw.) on creeping bentgrass putting greens (Senseman 2007). It was labeled for moss control on creeping bentgrass putting greens in July 2005, and research indicates that carfentrazone provides good to excellent control of silvery-thread moss over a broad temperature spectrum (Anonymous 2005; Boesch and Mitkowski 2005; Nelson 2007; Settle et al. 2006). Junction (mancozeb + copper hydroxide), a bactericide/fungicide, is also labeled for moss control on bentgrass putting greens (Anonymous 2006). Landschoot et al. (2004) investigated Junction and concluded that summer treatments did not control Bryum argenteum, however, fall applications of 5.0 oz. /1,000 square feet applied biweekly with 5 applications provided 100 percent moss control. Cook et al. (2002) concluded that five applications of Junction applied at 0.1 to 0.15 lbs. copper/1,000 square feet biweekly controlled Bryum argenteum for up to two years. However, copper accumulation in the soil medium could potentially induce iron deficiency in turfgrass plants. (Boesch and Mitkowski 2005; Landschoot et al. 2004) Landschoot et al. (2004) observed creeping bentgrass injury with multiple applications of Junction and attributed it to copper-induced iron chlorosis. Bryum argenteum control has also been observed with other chemistries, such as ferrous and ferric sulfates and sodium carbonates. However, control is erratic and appears to be dependent on environment (Boesch and Mitkowski 2005; Landschoot et al. 2004; Turgeon and Vargas 2006).
How was the data from the Moss study analyzed?

Does Quicksilver decrease moss populations?

Is moss control a long term project?
