Herbicide Action in Plants workshop December 5-6

 Understanding how different herbicides affect crops and how to differentiate plant injury from various herbicides will be among the topics discussed at a two-day University of Nebraska–Lincoln workshop this December.

Alex Martin and Mark Bernards, professors in the Department of Agronomy and Horticulture, will present Herbicide Action in Plants, a two-day workshop at the UNL East Union, December 5-6. The workshop, consisting of lecture, discussion and “hands-on” problem solving, is designed for individuals working in production agriculture. The conference will cover herbicide mode-of-action and provide participants a working understanding of plant herbicide interactions as a basis for understanding in-field herbicide performance.

The mode of action and plant response of all major herbicide families will be presented, with live plants used to demonstrate principles and serve as examples for problem-solving exercises. Participants will learn the symptoms caused by common herbicides, how rapidly they develop and what plant parts express the symptoms. The workshop will explain why herbicides with different modes of action may result in similar plant symptoms.

Herbicide selectivity will be examined, enabling participants to understand why herbicides kill weeds, but not crops. Participants will learn why some herbicides have greater crop safety than others; how crop safety and weed control are influenced by environmental conditions; and why herbicide-resistant crops and herbicide-resistant weeds are resistant to herbicides. Participants will also learn how safeners and common spray additives work.

The workshop, which is available for graduate academic credit, as well as noncredit (professional development) and CEU credit, is recommended for graduate students, certified crop consultants, certified professional agronomists, crop production and pest management industry personnel, producers, Extension educators, and science and vocational agriculture teachers.

Regular UNL admission procedures, tuition and fees apply for graduate students. For noncredit and CEU-credit participants, the cost is $250, if paid no later than November 28 and $300 thereafter. Individuals taking the workshop for noncredit or CEU credit can register online at: https://estore.adec.edu. The fee includes all course-related materials, parking permit, lunch and refreshments both days.
