The Effect Of Photocatalytic Titanium Dioxide And Ultraviolet B Radiation On Sclerotinia Homoeocarpa Growth And Pathogenicity, Chun Hu
Masters Theses
Photocatalytic TiO₂ [titanium dioxide] generates strong oxidative effects when illuminated with ultraviolet (UV) light with wavelengths of less than 385 nm. UVB has wavelengths ranging from 280 to 315nm. Previous research indicates the oxidative species and UVB radiation can react and cause cellular damage to microorganisms, which may reduce Sclerotinia homoeocarpa growth and help to control dollar spot disease development. The objectives of this study were to investigate the interactions of TiO₂ and UVB radiation, both in vitro and in vivo, on the growth and development of dollar spot. Factorial treatments consisting of five rates of TiO₂ and three doses …
Non-Target Effects Of Strobilurin Fungicide Applications On Creeping Bentgrass Putting Greens During Summer Stress, Jesse J. Benelli
Non-Target Effects Of Strobilurin Fungicide Applications On Creeping Bentgrass Putting Greens During Summer Stress, Jesse J. Benelli
Masters Theses
Previous research has indicated that strobilurin fungicide applications may improve summer stress tolerance of creeping bentgrass (Agrostis stolonifera L.) putting greens. In this experiment, strobilurin fungicides were integrated within a summer fungicide program to evaluate disease severity and plant physiological effects. Fungicide programs were applied on a ‘Dominant Southern’ creeping bentgrass putting green; all of which consisted of five fungicide spray applications from June to August during 2011 and 2012. The 2nd and 5th application in each program consisted of a strobilurin fungicide. Strobilurin fungicides evaluated included pyraclostrobin, azoxystrobin, fluoxastrobin, or trifloxystrobin. The remaining fungicide applications were …
