Abstract/Contents:"Microdochium patch, caused by Microdochium nivale, occurs in cool-humid regions like the Pacific Northwest. Fungicide applications suppress Microdochium patch although alternatives to fungicides are desired where pesticide restrictions occur. Previous research has shown that 97.7 kg FeSO4·7H20 ha-1 applied every two weeks in a 814 L ha-1 water carrier suppressed Microdochium patch, however unacceptable turfgrass thinning was observed. The objective of this research was to quantify the effects of four different water carrier volumes of 97.7 kg FeSO4·7H20 ha-1 applied every two weeks on the suppression of Microdochium patch, percent green cover, and turfgrass quality on an annual bluegrass putting green in Western Oregon. A seven-month field experiment was conducted on an annual bluegrass putting green in Corvallis, OR from September 2015 through April 2016 and repeated from September 2016 through April 2017. The study was arranged as a randomized complete block design with four replications. The experimental plots were 1.5 m2 and the total experimental area was 30 m2. Golfer traffic was replicated by walking over the plots with golf shoes. The treatments consisted of 97.7 kg FeSO4·7H20 ha-1 applied every two weeks in four different water carrier volumes (1019, 2037, 3056, and 4075 L ha-1) and a non-treated control. Treatments were applied using a handheld boom with four XR80015 nozzles attached to a CO2 pressurized backpack sprayer using a boom pressure of 280 kPa. Response variables included turfgrass quality on a 1 to 9 scale, percent disease, area under disease progress curve, and percent green cover. This research demonstrated that 97.7 kg FeSO4·7H20 ha-1 applied every two weeks suppresses Microdochium patch to equivalent levels regardless of carrier volumes ranging from 1019 to 4075 L ha-1. Higher carrier volumes resulted in higher percent green cover compared to lower carrier volumes. No treatment reduced turfgrass thinning to acceptable levels."
