June 7, 2013 Scouting Report
Undoubtedly everyone is waiting for this weather to end and that includes us turfgrass managers - or maybe not! This week on my way around the courses, meeting with superintendents it became clearly obvious how competitive Poa annua is, if it has the right conditions. The last ten days have been party time for Poa and while you may be scratching your heads, the continuation of what begun last week is far from your control. Temperatures have been around ideal for Poa with no consistent heat to benefit creeping bentgrass (Agrostis stolonifera L.) growth and this is following a long, wet winter - as I said last week - it's not surprising that it has been a tough start on Poa control this year. The weather data again has pointed toward cool conditions with lower light levels over the last week and it seems that until the middle of next week at least it will not let up. Unfortunately we cannot put up an umbrella and turn on the heaters and so communication with members is a key to management at this time of the year. Once the heat returns - the growth of Poa will go into reverse rapidly and lose density unfortunately. The biodiversity of Poa with annual and perennial biotypes and hundreds of others in between which all have adapted to YOUR golf course in some unique way makes them far more competitive than bentgrass - particularly in this weather.
