| Abstract/Contents: | "Ideally, classroom instruction provides the principles behind proper turfgrass management practices whereas field training exposes students to implementation methods. In turf, where quality is of primary importance, students exposed to wasteful management practices in the field without knowing the reasons behind them could accept these practices as proper. The purpose of this study was to evaluate students with past turf experience on their understanding of diseases and water management strategies using a simulation model. Forty-five students enrolled in turfgrass science were evaluated for comprehension of water and disease management principles using TURFBLIGHT, an interactive turfgrass management simulation model. TURFBLIGHT challenges students to maintain healthy turfgrass by (i) providing adequate moisture through irrigation to prevent turfgrass wilt and (ii) preventing or minimizing the disease damage from anthracnose (Colletotrichum graminicola) and pythium blight (Pythium spp.). The students were asked to develop a proposed budget for disease control and calculate water needed to maintain the turf given a set of daily temperatures and rainfall occurrences. Upon completion, students ran TURFBLIGHT given the parameters they developed in their proposed budget. For anthracnose, student actual fungicide sprays were comparable to their proposed number and the preventative program. In comparison to the ideal simulation, however, the actual number of student sprays was 60% higher, The anthracnose fungicide cost of the students simulation was 40% higher than the preventative program and 112% higher than the ideal simulation. Regarding irrigation, students overestimated the water needs by 91% over what was actually used. The amount of water used was 31% less than the preventative program yet 84% higher than the ideal irrigation program." |
