DIAGNOSIS OF TURFGRASS DISEASES

The role of the professional disease diagnostician has become increasingly important in turf management. Responsible turfgrass disease diagnosis must incorporate the possibility of biotic, as well as abiotic, disorders and should consist of three components: the interview, identification of the stress factor, and a management recommendation. The concept of management groups is introduced to facilitate delivery of the rapid and effective solution required by turf managers. Recent advances in diagnostics, including immunoassay, PCR kits, and distance diagnostics, have had minimal effect on turfgrass diagnostic practices to date. However, continued emphasis on the application of technology rather than knowledge-based diagnostic procedures is contributing to the demise of applied plant pathology. Nevertheless, the demand for turfgrass disease diagnostic services continues to increase, making the future for the applied plant pathologist somewhat uncertain, but full of opportunities.
