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.

Southern rust has been confirmed in corn in three eastern Nebraska counties this week. Corn fields should be scouted soon and frequently in the coming weeks for this and other diseases in case treatment is necessary.
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.
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.
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.
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.
