Turf Tip: Poa Seedhead Suppression Applications

"As spring emerges, golf course superintendents break their dormancy inside the office and investigate their courses to prepare for the upcoming season. One of their first chemical applications, often the trickiest to accurately time, is their poa seedhead suppression application. There are many schools of thought on when to apply the application for poa seedhead suppression. One is after the first forsythia bloom, using Growing Degree Days (www.gddtracker.net). The other is applying after identifying seedheads in "indicator" areas (South-facing slopes, near cart paths or asphalt). These methods all have merit and it may be wise to take all into consideration. It is vital to continuously check weather forecasts when planning your application. If there is a chance of frost within 48 hours after application, it is recommended to wait for warmer weather before applying. Some growth regulators, especially Embark (mefluidide), will have deleterious effects on turf quality if a frost occurs after application. My advice is to check the weather and use all information you have at your disposal, including past records, to decide when to apply. Also, be patient and use common sense."
