| Abstract/Contents: | "Dollar spot, caused by Sclerotinia homoeocarpa, is one of the most intensely managed diseases of turfgrass. Measurements of dollar spot severity have traditionally been in the form of visual estimates which do not maximize accuracy and precision, along with preventing minor differences in severity from being recognized. Furthermore, visual assessments may be labor intensive, time consuming, and affected by environmental changes during a rating period. Digital image analysis and mutispectral radiometry were evaluated for their ability to accurately assess dollar spot severity in the field. Data were compared with severity assessments obtained via qualitative visual assessments and a grid rating method. Significant differences existed among the four rating methods with digital image analysis providing the most accurate measurements. A study to further investigate the use of digital image analysis and multispectral radiometry is underway." |
