UNL WEED SCIENCE EDUCATION

Undergraduate Classes

AGRO220: Principals of Weed Science
This course is taught every spring semester at UNL. The course provides a background on weed identification and biology; weed interference in crops; weed control by preventive, cultural, biological, mechanical, and chemical means; herbicide terminology and classification; equipment calibration and dosage calculations.

Graduate Classes

AGRO896: Interplant Competition in Managed Ecosystems
This course is taught in alternate (odd) years during the spring semester. This course will focus on whole plant physiological response to solar radiation, water, and nutrients, and on interplant competition for these resources. Quantitative relationships useful for integrating the interactive affects of these factors on plant growth and interplant competition will be stressed. The course will be a mixture of lecture, discussion of relevant literature, and homework sets.

AGRO823: Herbicide Action In Plants
Herbicide Action in Plants is designed to provide graduate students and agribusiness professionals with a broad understanding of how herbicides kill plants and factors that influence herbicide efficacy. It is presented as a two day workshop followed by internet-based learning activities, and is available for graduate credit or as an extension workshop. Participants will learn how herbicides are absorbed into and translocated within the plant. They will explore seven common herbicide modes of action to learn what enzyme systems are disrupted by the herbicide, or what factors allow the plant to survive the herbicide. They will also acquire skills to identify herbicide injury symptoms and to troubleshoot ineffective herbicide applications. 

AGRO896: Sprayer and Spreader Technology
Sprayer and Spreader Technology will provide graduate students, agribusiness and landscape professionals with an in-depth understanding of ways to more effectively apply pesticides and granular fertilizers. It is presented as a hands-on two-day workshop followed by internet-based learning activities. Participants will explore key working components of agricultural and turf sprayers and spreaders. The most current nozzle technology will be demonstrated and discussed. Students will also learn about different formulation technologies and learn what impact they can have on applying pesticides effectively. Participants will gain skills in calibrating sprayers and spreaders, troubleshooting misapplications. They will also be challenged to think about application from the perspective of the pest or crop to insure that the application delivers the product to where it will do the most good. 

AGRO896: Pesticide Resistance Management
Resistance management is of paramount importance for preserving valuable pest control technologies. This multidisciplinary class overviews the mechanisms conferring resistance to herbicides, fungicides, and insecticides. Presented as a series of on-line lectures and internet-based learning activities, it will enable the student to develop skills to assess the value of different resistance management strategies. A key component of the class is gaining an understanding of population genetics and how a resistant gene is influenced by selection pressure and its initial frequency in the population. Students will also gain insight into currently advocated resistance management strategies and the models and studies that were used to develop them. This is a valuable class for anyone associated with the chemical or seed industry. 

AGRO410/810: Turf and Landscape Weed Management
This online mini-course provides a comprehensive, in-depth study of weed biology and control as applied to turfgrass and landscape management. The course examines the specifics of weed management and related control strategies, including non-chemical methods. Along with basic terminology and concepts, students learn why weeds appear, persist and dominate in turf and landscapes. Students also acquire skills to assist in weed identification; develop cultural programs to limit weed invasion and persistence; and develop knowledge to maximize herbicide efficacy and minimze environmental impacts. 

AGRO412/812: Crop & Weed Genetics
This online mini-course is designed to provide agronomy students and agribusiness professionals with an understanding of the genetic basis for variation observed in the field among crop varieties and weed populations, and provide insights into the development of new traits in crop varieties. Students learn how to apply classical and molecular genetic principles to explain variation observed in plant families and populations, and to interpret information gathered from whole-plant trait observation and molecular analysis. Examples from genetic studies on both crop and weed species are presented for student evaluation, and relationships between crops and weeds are discussed. 

AGRO411/811: Crop Genetic Engeneering
This course is designed to provide upper-level undergraduate and graduate students, as well as agribusiness professionals, with an introduction to genetic engineering, one of the most rapidly integrated and intensively scrutinized technologies applied to crop production in the United States. Students will learn the basic steps required to produce a genetically engineered crop, with emphasis on procedures used to develop current crops and innovations that will lead to future products. Students will become familiar with the genetic engineering process, learn how to predict how changes in the different steps of the process influence the final crop, and apply their knowledge of genetic engineering technology to plan the development of new genetically engineered crops. 

AGRO822: Integrated Weed Management (IWM)
This course begins with a one-day workshop consisting of lecture and discussion. The course is designed to provide graduate students and agribusiness professionals engaged in production agriculture with a working understanding of Integrated Weed Management (IWM) principles as a basis for understanding weed control issues. IWM, which is based on a multidisciplinary approach to weed control, provides information on the need for and timing of weed control, the effective and environmentally sound use of herbicides, and alternatives to herbicide use, including new techniques, such as "weed flaming."

Extension Education

Crop Protection Clinics (CPC)
This series of one-day clinics is held at 12 locations throughout Nebraska during the month of January. The clinics provide information beneficial for crop consultants, custom applicators, dealers, farmers, and professional agriculturalists. Insect, plant disease, and weed science topics will be addressed.

Crop Management Diagnostic Clinics (CMDC)
Held at a site developed exclusively for the clinics, the expertise of University and industry agricultural specialists and professionals is drawn upon to provide the latest, most up-to date information. Presentations include hands-on-activities or field demonstrations in small groups to encourage interaction between presenter and participants.

Soybean Management Field Days (SMFD)
Soybean Management Field Days offer producers unbiased and research-based information to improve their soybean profitability. The event consists of four field stops across the state, each with demonstration plots, lunch and time for questions. Producers can obtain ideas and insight about the challenges they face in producing a quality crop at a profitable price in today's global economy.

The field days are sponsored by the Nebraska Soybean Board in partnership with Extension in the Institute of Agriculture and Natural Resources and are funded through checkoff dollars.

Crop Scout School
Crop scout training is a comprehensive, hands-on day intended to get individuals the skills they need to identify insects, plant pathogens, and weeds in agronomic crops. Classes are held at the Agricultural Research and Development Center (ARDC) near mead, in March and May.
