Ben,
I'm in SW Okla with L93 Bent on USGA Spec greens constructed in 07. Prior to that we used Scotts goose/crab (as it was then) split rate 6-8 weeks apart Mar and early May on the old push ups with good results, however had some trouble with keeping areas of bent through summer sometimes (could have been other management practices) so we switched to dithiopyr using both the Andersons product with fert labeled for greens and sprayable dimension when it was labeled for greens with good results. Following the renovation was an explosion of goose with the disturbed soils starting from the collar area. Since then we treat 18' out from the green with Andersons Goose / Crab and the green. The collar gets a full rate late Feb and half rate mid May. The greens get a split rate 1st half late Feb and 2nd half end Mar followed by a half rate in mid May that is one lap inside perimeter of the greens as this was the most concentrated area of the goosegrass. Good results with this for the past 2 seasons, however I feel our management practices have improved considerably throughout the years with root deveploment and going into the June, July, August period strong. Water management on bent greens is key for us.
