Abstract/Contents:"Bellfontaine location, Metsulfuron, Imazapic, and Pinolene ® were applied to newly mowed hwy. Turf on April 19, 2000. On the same day we made an apllication to an unmowed section of turf. In these two tests we wanted to see if the turf quality was effected by mowing, Vs turf not mowed. We also wanted to know what kind of growth regulation we could achieve, along with weed control, and seed head suppression. The plots consisted of KY Bluegrass, Rye, Fescue. Weed control was in the 90%. Growth regulation was dramatic on both plots holding the turf to almost no growth for the first 6 weeks, and at 12 weeks it was still holding the growth. Seed head suppression was very good in the 80% range. The quality of the turf remained good in the 80% range. The quality of the turf remained good on both plots but we did notice a darker green color to the turf that was not mowed. My conclusion is that the turf that was not mowed was able to withstand the dry period better. Both plots had a better color than the untreated areas, and the turf quality was better. The turf along this hwy was very rough turf that had not been mowed on a regular basis, with a lot of high and low areas, which in turn put stress on the turf from the standpoint of dry areas, and areas that held too much moisture. Van Wert location; The same three products were applied at this location on the same day April 19, 2000. This area was not mowed, but it did have a better quality turf consisting of Blue grass, Fescue, Rye, and some native grasses. Weed control was excellent in the 90% range. The plot was checked every 2 weeks and after 8 weeks we had very little growth. Seed head suppression was very good in the range of 85%. After 12 weeks the growth was still being held back to the point where you still wouldn't have to mow and it would look acceptable for a roadside. We did experience some native grasses that came out of growth regulation within 4 to 5 weeks, and at 12 weeks the clumping of native grasses was evident. Summary, The Metsulfuron, Imazapic, Pinolene, combination gave outstanding turf growth regulation, seed head suppression, and acceptable weed control on hwy right-of-way for 12 weeks. The quality of the turf remained good, and we noticed an enhanced green color."
