Abstract/Contents: | "Research on primary nutrient nitrogen (N), phosphorus (P) and potassium (K) ratios have suggested that maintaining the proper balance of the nutrients is critical to disease mitigation. However, research on N, P, and K ratios relevant to annual bluegrass and Microdochium patch is not available. The objective of this research is to evaluate the effects of fall through spring monthly applications of N (9.8 & 4.9 kg N ha-1), P (0 & 1.22 kg P ha-1), and K (0 & 4.9 K ha-1), on Microdochium patch development within an annual bluegrass putting green in the absence of traditional fungicides. Field research was initiated in September 2018 on a 100% USGA sand-based putting green which was constructed in 2009 at the Lewis-Brown Horticulture Farm, Corvallis, OR. Experimental design is a 2 by 2 by 2 factorial randomized complete block design with four replications; factors include nitrogen rate, phosphorus rate, and potassium rate. To reduce the disease pressure, all of these treatments received monthly applications fall through spring of phosphorous acid (Duraphite 12 applied at 3.7 kg H3PO3 ha-1) and sulfur (Sulfur DF applied at 12 kg S ha-1), fungicide alternatives that have shown promising results for control of Microdochium patch. Traditional fungicides will not be applied to this experiment for the duration of the study, except for summer anthracnose control. We found that the high rate of N resulted in more disease than the low rate of N. Potassium applied at a rate of 4.9 kg N ha-1 reduced percent disease when compared to treatments that did not receive K. The main effect of P rate and the interactions between N, P and K were not significant." |
