| Abstract/Contents: | "Research has shown that macronutrients such as nitrogen (N), phosphorus (P), and potassium (K) can have an effect on Microdochium patch development individually; however, no research is available on the effect of N, P, and K ratios on Microdochium patch. A 3-yr field study was initiated in September 2017 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 on an annual bluegrass putting green. Treatments were arranged in a 2 by 2 by 2 factorial design with four replications; factors include nitrogen rate, phosphorus rate, and potassium rate. Nitrogen applied alone resulted in greater Microdochium patch severity, compared to N applied in combination with P and/or K, regardless of N rate. The main effect of potassium was significant in both year 1 and 2; with K applied at 4.9 kg ha-1 reducing disease severity compared to no K. Phosphorus rate and the interaction between N, P, and K did not have an effect on disease severity in either year of the study." |
