Dr. Giesler provides statewide leadership for extension plant pathology programs in alfalfa, soybeans, ornamentals and trees. Soybean acres are expanding in Nebraska at this time and as a result are where Dr. Giesler spends most of his effort. His research projects in soybean include Bean pod mottle virus, Soybean Cyst Nematode and Phytophthora root and stem rot. Other projects include annual rose fungicide trials for black spot management and other ornamental diseases as they emerge. He is also working on injection studies in pine to manage Pine Wilt Nematode with Dr. Mark Harrell of the Nebraska Forest Service.

Management studies on soybean viruses and germplasm evaluations to find tolerance to Bean Pod Mottle Virus. Efficacy trials for soybean seed treatment fungicides and development of an integrated management program for Phytophthora sojae. Soybean rust fungicide application studies with USDA and national leader for identification of soybean rust. Toured South America rust fungicide efficacy trials in 2004 and 2005.
