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.

Corn Disease Update: Southern Rust Confirmed in 10 Nebraska Counties
July 29, 2016
Southern rust has been confirmed in samples from 10 Nebraska counties — Adams, Butler, Clay, Fillmore, Lancaster, Nuckolls, Pierce, Polk, Thayer, and Valley. All were from fields with a low incidence of disease at the time. Growers should also be scouting for rust as well as gray leaf spot, common rust, and physoderma brown spot.
Corn Disease Updates Aug. 4-5; Samples Welcomed
July 28, 2016
Corn Disease Updates, hosted by Nebraska Extension and sponsored by the Nebraska Corn Board, will be held at three more sites in the next two weeks.
Corn Nematodes: Scout Sandy Soils Now, Other Soils Any Time
June 7, 2016
This year nematode damage in some Nebraska fields may be masked by the ample rainfall we’ve received, but rest assured, these plant parasitic nematodes are still there in almost every field. Their impact ranges from no obvious sign to severe crop injury and tremendous yield loss.
Seedling Diseases Continue to Develop in Nebraska Corn
June 2, 2016
Following several weeks of rainy conditions, seedling diseases are becoming more apparent in corn. See what symptoms to look for when scouting fields.
Seedling Diseases Developing in Corn
May 20, 2016
With cool wet conditions favorable for corn seedling disease development, growers are urged to scout for inconsistent stands and disease pressure. This week seedling diseases were documented in 10% of surveyed fields in Dodge County in eastern Nebraska, mostly in corn-after-corn fields in river valleys. Be sure to monitor seedling emergence and stand establishment across the state during the coming weeks so that if problems occur they can be detected as early as possible.
Wet Conditions Favorable for Seedling Diseases in Early Planted Corn
April 28, 2016
Wet field conditions and cool soil temperatures across Nebraska may put early planted corn at added risk for seedling diseases. Be sure to monitor seedling emergence and stand establishment in the coming weeks so that if problems occur they can be detected as early as possible.
