Abstract/Contents: | "Creeping bentgrass (Agrostis stolonifera L.) is a major weed problem in home lawns, athletic fields, and golf course roughs. The influence of mesotrione and triclopyr were assessed for their ability to selectively remove creeping bentgrass from Kentucky bluegrass (Poa pratensis L.). This study was conducted at the University of Connecticut Plant Science Research and Education Facility located in Storrs, CT. An average of 39% creeping bentgrass was present when the study was initiated. Triclopyr and mesotrione each were applied at two rates on a 14-day interval for a total of two, three or four applications. All treatments were applied using a CO2 pressurized sprayer calibrated to deliver 467 l/ha water. Regardless of herbicide rate, all plots treated with triclopyr and mesotrione exhibited significant injury with 4 and 7 days following treatment, respectively. Three months after the initial treatment (19 September), creeping bentgrass populations within all herbicide-treated plots were reduced when compared to the untreated control. On most rating dates, excellent control (<= 5% bentgrass) was achieved within plots receiving >= 3 applications of mesotrione (0.125 and 0.187 lb ai/A) and three (1.0 lb ai/A) or four (0.5 and 1.0 lb ai/A) applications of triclopyr. Plots treated with two applications of mesotrione (0.187 lb ai/A) resulted in moderate levels of creeping bentgrass control. On the final rating date, there were no differences in creeping bentgrass cover among plots treated with two (0.5 and 1.0 lb ai/A) or three (0.5 lb ai/A) applications of triclopyr or two applications of mesotrione (0.125 oz lb ai/A) and the untreated control. Unlike triclopyr, mesotrione did not appear to inhibit regrowth of Kentucky bluegrass into areas void of turf." |
