| Abstract/Contents: | "The phosphonate fungicides contain the active ingredient phosphite (PO3). Fosetyl-Al was the original phosphonate and is effective for control of certain diseases, but also improves turfgrass quality in the absence of disease activity. Several new phosphonates containing K, Na, or NH4 salts of PO3 are being marketed to turfgrass managers. This research was performed to determine the impact of phosphonates on the quality of creeping bentgrass putting greens when applied alone or combined with contact fungicides. Treatments included two fosetyl-Al formulations (Aliette and Signature) and three PO3 salts (Alude, Magellan, and Magnum) applied at 9.8 kg a.i. ha-1. These were applied alone or combined with chlorothalonil (8.1 kg a.i. ha-1) or mancozeb (19.5 or 9.8 kg a.i. ha-1). Treatments were applied on 14-day intervals from June to August in 0.08 L m-2. The phosphonates did not increase turf quality in 2003. Fosetyl-Al formulations increased turf quality on one date in 2004 and three dates in 2005, and PO3 salts improved turfgrass quality on two dates in 2005. The contact fungicides chlorothalonil (8.1 kg a.i. ha-1) and mancozeb (19.5 kg a.i. ha-1) consistently increased creeping bentgrass quality in all years. While the phosphonates increased turf quality under certain conditions, more consistent benefits were provided by chlorothalonil or mancozeb." |
