8:30 – 9:30 a.m.
Multi-spectral Imaging using Unmanned Aerial Vehicles for Identification of Rose Diseases and Abiotic Issues
Dr. Mathews Paret, Dept. of Plant Pathology, University of Florida
In recent years, the use of Multi-spectral imaging sensors has been increasingly studied to understand the spectral reflectance patterns in plants as a response to diseases and other abiotic issues. These studies have generated useful information on green NDVI (Normalized Difference Vegetation Index), red NDVI, red-edge NDVI and other stress index parameters in many crops. This presentation will present findings from recent studies on standardization of these approaches on roses for early detection of hotspots of diseases and abiotic issues.
9:30 – 10:30 a.m.
Assessing Tree Damage after Storms and Steps to Recovery
Dr. Andrew Koeser, Dept. of Environmental Horticulture, GCREC, University of Florida
Tree damage caused by strong winds and flooding can negatively impact urban tree longevity. The first step of any tree restoration plan is a thorough assessment to determine whether the tree is worth the time and energy. Various factors such as the size and age of the tree should be considered. Dr. Koeser will discuss first-response immediately following the storm, and steps to develop and implement a multi-year restoration pruning plan. Communities should recognize the importance of tree management programs, especially in hurricane-prone areas. As urban sprawl removes forests and plants urban trees, the work of arboriculturists is becoming increasingly important for saving and maintaining this valuable green resource.
