Dr. Giesler provides statewide leadership for extension plant pathology programs in soybeans and turfgrass diseases. He is the team leader for the Extension Plant Pathology Team which is a Nebraska group of extension Plant Pathologist responsible for disease management programs throughout Nebraska. His main program focus is in soybeans and has included research projects on Bean Pod Mottle Virus, Soybean Cyst Nematode, Foliar Diseases and seedling diseases including Phytophthora root and stem rot. He conducts disease management studies on soybean to evaluate the efficacy of soybean seed treatment fungicides and foliar products. He served as a national leader for identification of soybean rust, coordinator for national soybean rust sentinel monitoring efforts from 2003 through 2012, and toured South America rust fungicide efficacy trials in 2004 and 2005. Dr. Giesler is currently working on several studies on soybean cyst nematode to improve management programs for this significant pest of soybean. Through continued support of the Nebraska Soybean Board, a free soil sampling program for SCN is operated in his program that provides soybean farmers a way to determine if SCN is present in their fields.
A farmer who is ordering soybean seed this fall asks "At $20 per unit, when does soybean seed treatment pay?" Here's what to consider when deciding whether to order fungicide and insecticide treatments for your soybean seed this year.
Loren Giesler has been named head of the Plant Pathology Department at the University of Nebraska–Lincoln, effective Sept. 1, 2018. A long-time contributor to CropWatch, Giesler is a professor and extension plant pathologist in the department.
Soybean plants are generally able to withstand a fair amount of flooding in the short term; however, diseases favored by wet conditions may become a problem for the rest of the season. Research shows the length of time the soil is wet and the type of soil will affect plant injury and survival.
After recent severe storms that rolled across parts of Nebraska, growers are encouraged to wait 7-10 days to fully assess crop damage and determine next management steps. Research-based estimated yields from replanting now are included.
Symptoms of bacterial diseases can be easily confused with those of fungal diseases in field crops. This article, from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics, reviews some of the common mistakes made in the major field crops and reviews research on the impact of fungicide use after hail events in corn and soybean.
