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.

Nebraska Plant Pathology: A Culture of New Diseases
January 23, 2019
Though relatively small, UNL's Department of Plant Pathology has played a significant role in the discovery of many economically important plant diseases, including most recently, a new fungal pathogen causing Fusarium head blight of wheat. This article is from the 2019 Nebraska Crop Management Conference Proceedings.
What’s New in Plant Pathology
January 9, 2019
This article, from the Proceedings of the 2019 Crop Production Clinics, addresses new and updated product labels for disease management, a report from the Plant and Pest Diagnostic Clinic, changes in the Department of Plant Pathology, and the initial US finding of Fusarium boothii on wheat in Nebraska.
Soybean Disease Update
January 11, 2019
In 2018 an array of weather conditions led to the development of several soybean diseases. Excessive early season moisture and heavy rains during the season resulted in many fields being impacted by Phytophthora root and stem rot. Frogeye leaf spot developed early in some areas and continues to build in the state with more fields being affected.
Corn Disease Update
January 9, 2019
The 2018 crop season got off to a slow start with cold, wet conditions delaying planting in much of the state. Some seedling diseases developed in early planted corn, but with ample heat units the corn caught up quickly and most of the crop finished ahead of schedule. High relative humidity and rainfall drove the development of several leaf diseases mid-season.
Stalk and Grain Quality Likely to Decline During Wet Weather
October 12, 2018
Stalk and ear rot diseases continue to become more evident in many cornfields across Nebraska where prolonged periods of wet weather have delayed corn harvest.
Cercospora Purple Seed Stain and Blight in Some Nebraska Fields
September 19, 2018
High humidity and warm temperatures created conditions optimal for development of Purple Seed Stain and Blight in some Nebraska soybean fields.
Stalk Rot Diseases in Nebraska Corn Fields
September 13, 2018
Knowing the risk factors for stalk rot can help you evaluate those fields first and prioritize your harvest schedule accordingly. Submitting plant samples and determining which stalk rot is present can help you better prevent or manage it in future years.
Crop Disease Update
August 10, 2018
Plant pathologists report on the corn and soybean diseases they're seeing. Bacterial leaf streak has now been confirmed in 70 counties and Southern rust was confirmed in three more counties.
