Silver moss likely to thrive this season

Greenkeepers are being warned to be aware that the current conditions are rife for silver moss to thrive.

Greenkeepers are being warned to be aware that the current conditions are rife for silver moss to thrive.

Disturbed areas, with tightly trimmed grass, under high stress can lead to an increased risk of colonisation by silver moss, explains Alan Horgan, Certis’ Technical Officer.

“Greens are generally kept to a mowing height below 3.5mm, and this constant mowing stresses the turf, which favours moss establishment.”

He adds that the thatch is important, as it provides a moisture retentive surface, which is essential for moss to establish and then persist.

“To control moss, and especially silver moss, there is demand for a product that targets the roots,” explains Alan. “However, traditional iron based treatments do not effectively control silver moss in my experience,” he adds. “In trials, Mogeton has shown to be fully effective at controlling this tenacious moss species; it worked well and targeted the moss deep into the roots. This allows Mogeton to fill a niche in the market of moss control on greens and tees - the high value turf.”

Silver moss by its nature develops in dry and sandy turf which tends to mean it’s a real problem on tees and greens, which is the opposite to other moss species, comments Alan. “It is also the case that silver moss tends to form in small patches, again suiting the targeted spot treatment application that is recommended with Mogeton.”

Alan reiterates the importance of careful and responsible use with this much needed product. “Users need to adhere to the label application rate of 1.5g/m2 (15kg/ha). With one application permitted per calendar year, greenkeepers are urged to carefully plan ahead for the strategic use of Mogeton,” concludes Alan.
