| Abstract/Contents: | Presents a preliminary study with the following objectives: "(1) to determine if three levels of white grub infestation in greenhouse turfgrass can be discriminated using a non-imaging spectrometer and (2) to determine specific wavelengths or vegetative indices that are more sensitive to damage resulting from white grub injury in turfgrass." Results include that "no significant differences among treatment means were found seven days after grub introduction for any of the wavelengths or indices tested. Sixteen days after infestation, the treatment 3 stress index mean was significantly different rom the treatment 2 mean. Thirty-one days after infestation, treatment 3 was significantly different from treatments 1 and 2 for all wavelengths tested in the 650-700 nm range and for all growth and stress indices." Concludes that "high level grub damage can be clearly distinguished from zero and intermediate damage four weeks after infestation, using wavelengths in the 650-700 nm range and using growth and stress indices. Growth indices such as NDVI, and stress indices appear to be more sensitive to grub-induced damage in turfgrass than do individual wavelengths or bands. Differences between treatments could not be separated using neaer infrared wavelengths (800-950 nm) on any of the sampling dates. An index of stress may be more effective at differentiating early grub damage than other indices. Field studies with additional levels of grub infestation are needed and will be conducted during the summer of 2001." |
