| Abstract/Contents: | "Strategies for mitigating turf injury from hydraulic fluid (HF) spills are lacking. Research was conducted in 2014 to determine if washing HF spills with water reduced injury area (IA) on a hybrid bermudagrass (Cynodon dactylon [L.] Pers. var. dactylon x C. transvaalensis Burt-Davy var. 'Tifeagle') putting green. If washing reduces IA then turf injury should heal faster. To test this hypothesis a split-plot field experiment was conducted. Three mL hot (80° C) petroleum HF (PHO), vegetable HF (VHO), or synthetic HF (SHO) were applied to turf in a single spot. After 75 min spills were washed with water or left unwashed. Resulting IA was determined over 38 d using image analysis. Washing reduced IA for SHO and PHO (p = 0.0198) but not for VHO. Injury area for SHO averaged 2.2 (washed) and 12.6 cm2 (unwashed) at 38 DAT (p = < 0.0001). For PHO it averaged 39.9 and 47.1 (p = 0.0306) and for VHO it averaged 32.1 and 32.5 (p = 0.7678). Fitting a hyperbolic-linear model to IA data over time produced best-fit regression lines for all HF. Modeling indicated the rate of change in IA expansion and contraction differed between SHO treatments (p = < 0.0001). Washing slowed the initial rate of expansion (p = 0.0525) and accelerated the rate of contraction (p = < 0.0001). This was not observed for non-polar HF. Predicted healing time was reduced to 65 d (SHO washed) compared to > 120 d (SHO unwashed). Predicted healing for non-polar HF was > 200 d regardless of treatment. Washing SHO with water reduced IA and hastened turf recovery confirming the hypothesis. This was attributed to SHO being soluble in water. Washing non-polar HF with water was not an effective turf injury mitigation strategy." |
