That means an application that may have persisted only a few weeks during summer heat can remain active considerably longer during fall. <\/span><\/p>\n

GreenKeeper\u2019s wetting agent models account for these changing temperatures, making this a good time to stop relying on fixed calendar intervals and use the <\/span>Wetting Agents<\/strong><\/span><\/em><\/a> view in Program Builder<\/strong><\/span><\/em><\/a> to determine when another application is actually needed.

Prepare for winter while turf is still growing<\/span><\/h5>\n

There is another reason not to simply shut down the wetting agent program when summer ends. Fall is an important period for both cool- and warm-season turf to enter winter with adequate plant-available water. Applying a wetting agent while turf is still actively growing can improve soil-water uniformity before cold weather arrives and may become especially valuable if winter brings extended periods without dependable precipitation or snow cover. That deserves extra consideration this year as a strong El Ni\u00f1o continues to develop and shifts the probability of winter weather patterns across North America.\u00a0<\/span><\/p>\n

Wetting agents are important tools for all turf managers to save water, improve turf health and aid survival during tough winter weather. Use GreenKeeper App’s proprietary GDD models to help schedule these applications as the weather cools. <\/span><\/p>\n

Wetting models are currently available in GreenKeeper for <\/span>Brilliance<\/a><\/span>, CounterAct Firm<\/span><\/a>, CounterAct Retain<\/span><\/a>, Rely III<\/span><\/a>, Revolution, TriCure AD, and Pervade \u2013 Push Water<\/span><\/strong>. Be sure to select these products from the <\/em><\/span>Public Product list<\/strong> when scheduling the application so GreenKeeper knows to display the wetting agent performance model on the page.<\/em>\u00a0<\/span><\/p>\n
