Expert Bio

Andrew Kniss is an Associate Professor of Weed Ecology & Management in the Department of Plant Sciences at the University of Wyoming. He has a PhD in Agronomy with a minor in Statistics. Andrew's research program focuses on developing weed management programs in agronomic crops, especially sugarbeet, winter wheat, corn, and dry edible beans.

He has authored or co-authored 20 peer-reviewed journal articles and 1 book chapter. He teaches undergraduate and graduate level courses including Ecology of Plant Protection, Weed Science & Technology, and Applied Dose Response Analysis. He recently received the Outstanding Weed Scientist – Early Career award from the Western Society of Weed Science, and serves on the Board of Directors of the Weed Science Society of America. He grew up on a small farm in Nebraska. His interest in weeds began early in life after being forced against his will to pull nightshade berries out of dry bean windrows prior to harvest (he now thanks his dad for that experience).

Genetically Engineered Herbicide-Resistant Crops and Herbicide-Resistant Weed Evolution in the United States

By Andrew Kniss - Jan 09, 2018

The following is an abstract from a study by weed scientist Andrew Kniss about the correlation between GMO crops and weed resistance.  Genetically engineered (GE) herbicide-resistant crops have been widely adopted by farmers in the United States and other countries around the world, and these crops have caused significant changes in herbicide use patterns. GE crops have been blamed for increased problems with herbicide-resistant weeds (colloquially called by the misnomer “superweeds”); however, there has been no rigorous analysis of herbicide use or herbicide-resistant weed evolution t [...]
