Chemical Methods of Moss Control on Golf Course Putting Greens
2005
Boesch, Brian P. | Mitkowski, Nathaniel A.
Many golf courses throughout the United States are perennially affected by moss encroachment. Unfortunately, moss control products must often be applied at regular intervals throughout the season and can be very phytotoxic. In addition, application timing impacts efficacy. Copper in the form of copper hydroxide + mancozeb (Junction) can control moss when applied on a biweekly basis at 0.2 lb/1000 ft² with minimal phytotoxicity. Season-long application may be required on heavily infested greens and fall applications are often most effective. Higher rates can severely damage turf. Silver nitrate is extremely effective at eliminating moss infestations in 1 to 2 applications at 0.275 lb/1000 ft² without phytotoxicity. However, silver is currently not labeled as a pesticide. Carfentazone (Quicksilver) has been labeled for use against moss and appears to be very effective in reducing up to 90% of moss when applied twice at a 14-day interval of 6.7 oz/acre [* see erratum]. Terracyte applied at 14-day intervals at no more than 8 lb/1000 ft² can also successfully combat a moss infestation but season long application may be necessary and higher rates can cause dramatic turf injury. Other products that have met with limited success include iron, lime, chlorothalonil and soap-based products, which often fail upon repeated trials.
