Tamra Jackson-Ziems, Extension Specialist and Professor, joined the faculty of the Department of Plant Pathology at the University of Nebraska-Lincoln (UNL) in April 2005 after completing her graduate degrees at the University of Arkansas and University of Illinois-Urbana. Her appointment is split between extension, research, and teaching 80/10/10%, respectively, with statewide responsibility for diseases of corn and grain sorghum. Her extension activities encompass educating clientele about disease identification, prevention, and management. And her research projects encompass a broad range of topics, including bacterial leaf streak, Goss’s bacterial wilt and blight, use of fungicides for disease control, and plant parasitic nematodes of corn. During her time at UNL, she has delivered more than 180 invited presentations in 16 states and is the 2016 recipient of both the Nebraska Cooperative Extension Association’s Award for Outstanding Creative Programming (for an individual) and the Nebraska Ag Business Association’s Education and Research Person of 2016 Award.

It is a busy time of year as harvest begins across the state, but this is the perfect time to collect soil samples for soybean cyst nematode while waiting in the field in a grain cart or truck as the combine fills.
Following identification of southern rust, Phytophthora root and stem rot, and frogeye leaf spot in areas throughout the state, producers are encouraged to scout and be prepared to apply the appropriate fungicide treatments.
Now is the perfect time to think about how you can minimize diseases next growing season. Planting disease-resistant hybrids and varieties may be a more economical way to manage certain diseases, reduce disease severity and reduce dependence on pesticides.
Poor stalk quality can cause stalk lodging and breakage, leading to harvest difficulties. This could cause yield loss and create issues of volunteer corn for next year's crops due to ears lost from lodged corn.
Time spent waiting in a grain cart or truck on the edges of fields while the combine fills may feel like wasted time and lead to frustration. Why not make the most of that time by using it to collect soil samples for soybean cyst nematode (and other) analyses?
Patches of yellowing or dying soybeans have been observed and are a cause of concern across many areas of Nebraska. Some of these areas are due to several diseases described here, but other conditions may impact the development of these spots.
