Abstract/Contents:"Field studies were conducted to assess the influence of nozzle type on the control of Sclerotinia homoeocarpa, causal agent of dollar spot on creeping bentgrass (Agrostis stolonifera). Studies were conducted on golf course fairways located in Connecticut and Pennsylvania. Plots consisted of 1.5 × 3 m plots and were arranged as a randomized complete block design with four replications. Nozzles were selected to produce droplet sizes that are extremely coarse (TTJ11004), very coarse (AI11004; air induction), coarse (TJ11003), medium (XR11004), and fine (XR11003). All nozzle types were used to apply chlorothalonil (4.5 kg ai ha(-1)), propiconazole (0.23 kg ai ha(-1)), or a tank-mix of the two. All fungicides were applied at 44 gal H(2)O per A on a 14-d interval. Disease severity was assessed by counting the number of dollar spot infection centers. Regardless of nozzle type, all fungicides reduced dollar spot, when compared to the untreated control. Superior disease control, however, was provided when fungicides were applied as a tank-mix rather than alone. Dollar spot suppression generally was improved when fungicides were applied with XR11004, XR11003, and AI11004 nozzles. Moderate and poor dollar spot suppression was achieved with TJ11003 and TTJ11004 nozzles, respectively. Results indicate that the efficacy of fungicides applied in low water volumes can be improved through the selection of proper nozzles."
