| Abstract/Contents: | "Field experiments were conducted in 1997 and 1998 at the Great Smokies Resort in Asheville, NC, to evaluate the effects of postemergence (POST) herbicide applications on false green kyllinga (Killinga gracillima Miq.) in cool season turfgrass species. Herbicides were applied POST in a randomized complete block design to 5 by 10 foot plots at 32.5 GPA. Herbicide treatments were halosulfuron at 0.62 lbs. ai/a, either as a single application or followed by a four week sequential application, alone or in combination with MSMA at 1 or 1.5 lbs ai/a. MSMA treatments were initial applications of 1 or 1.5 lbs. ai/a followed by a one week sequential treatment at the initial application rate. Bentazon + 1% crop oil v/v was applied at 1 lb ai/a alone or in a tankmix with MSMA at 1 or 1.5 lbs. ai/a. All bentazon treatments received a 1 lb ai sequential bentazon appli- cation seven days after initial treatment. The sites were mixed bentgrass-Kentucky bluegrass-perennial ryegrass fair ways mowed at 0.5 inches. Rainfall was normal in 1997 but conditions were extremely dry in 1998. In 1997, bentazon applications controlled kyllinga>96%. Kyllinga was controlled>85% with halosulfuron and halosulfuron plus MSMA at any rate 6WAT. Treatments containing bentazon were the only applications which adequately controlled false green kyllinga in 1998. Kyllinga control was>92% 6WAT with bentazon alone or in combination with MSMA at 1.5 lbs. No significant turfgrass phytotoxicity was observed in any year. Turf quality declines were due to phytotoxicity imparted by treatments on heavy kyllinga infestations. Halosulfuron adequately controlled false green kyllinga in a year with abundant moisture. However, under drought conditions control was reduced. Bentazon applications resulted in good to excellent control in both years." |
