| Abstract/Contents: | "Common carpetgrass [Axonopus fissifolius (Raddi) Kuhlm.] is a stoloniferous warm-season turfgrass that tolerates high soil moisture and low soil fertility. Adaptation to reduced light environments has created an interest in carpetgrass as groundcover in solar panel farms and similar low-input environments. However, weeds infesting these areas may provide additional challenges due to canopy height or inflorescence production; therefore, data evaluating carpetgrass tolerance to postemergence herbicides is warranted. Research was conducted on a common carpetgrass rough at the Pine Hills Golf Course in Winder, GA during the summer of 2022. Herbicides were applied with a CO2 backpack sprayer calibrated to deliver 375 L ha-1 at 241 kPa. Treatments were initiated on 24 June 2022 and consisted of MSMA at 2.3 kg ai ha-1, dicamba + iodosulfuron + thiencarbazone at 0.18 kg ai ha-1, metsulfuron at 21 g ai ha-1, carfentrazone + 2,4-D + MCPP + dicamba at 0.34 kg ai ha-1, halauxifen-methyl + fluroxypyr + dicamba at 0.23 kg ai ha-1, penoxsulam + sulfentrazone + dicamba + 2,4-D at 0.34 kg ai ha-1, mesotrione at 0.18 kg ai ha-1, carfentrazone at 25 g ai ha-1, and MCPA + fluroxypyr + dicamba at 1.4 kg ai ha-1. A non-treated check was included. Carpetgrass phytotoxicity was 11 and 73% in response to dicamba + iodosulfuron + thiencarbazone and MSMA, respectively, 2 weeks after treatment (WAT), with corresponding NDVI of 0.68 and 0.37. Phytotoxicity increased to 46% 4 WAT in response to dicamba + iodosulfuron + thiencarbazone and decreased to 56% in response to MSMA. At 8 WAT, phytotoxicity was 19% in response to MSMA with NDVI of 0.72. No other treatment resulted in phytotoxicity or NDVI significantly different than the non-treated throughout the experiment. This research identified several postemergence herbicides that can be safely applied to carpetgrass for broadleaf and grass weed control." |
