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.

What’s New in Plant Pathology: Changes in the Plant & Pest Diagnostic Clinic
January 8, 2018
New to the Plant and Pest Diagnostic Clinic is Kyle Broderick, who became coordinator after working as an extension technologist in a University of Nebraska soybean pathology lab for six years. An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics.
Differentiating Corn Leaf Diseases
June 29, 2018
Symptoms of various corn leaf diseases can look very similar in the early stages. Here's how to differentiate one from another of those recently reported in the state.
Flooding and Ponding in Corn
June 22, 2018
Ponding or flooding of fields affects corn differently at different stages, depending on duration of flooding and other factors. Growers should assess the potential for nitrogen loss and increase scouting for corn disease in these fields.
Severe Storms and Hail-Damaged Crops: Steps for Making the Right Decisions
June 14, 2018
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.
Conditions Right for Development of Corn Diseases
June 7, 2018
Severe weather and wet conditions across much of Nebraska this week may favor increased development of diseases in corn, particularly bacterial leaf streak and Goss’s bacterial wilt and blight. For assistance in correctly identifying diseases, submit samples to the Plant & Pest Diagnostic Clinic.
Fungicides are for Fungi
January 8, 2018
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.
