That another glyphosate-resistant weed has been documented in Michigan? Glyphosate (originally marketed as Roundup) is a widely used herbicide, and its extensive use was predicted to lead to selection for varieties of weeds that can resist the deleterious effects of the chemical. Indeed, genes that confer resistance have been deliberately introduced into the genomes of crops to allow use of glyphosate on fields of growing crops. That there would be natural genetic variations that confer resistance and that those would benefit from the selection process of extensive herbicide use is not surprising. So enough on the lecture – why bring this up? Because I learned about this at the Agriculture/Agribusiness news website, http://www.news.msue.msu.edu/! The specific story was written by crop and soil sciences associate professor Christy Sprague, and the article refers to Extension educator Dan Rajzer or Dr. Sprague for answers to further questions. I continue to find the news site helpful and impressive, and even if the information it’s offering on a particular day isn’t of interest to a particular viewer, it’s still impressive to see the breadth of expertise and information that Michigan State University Extension provides for farmers, agribusiness operators and landscape managers. It tells our story much more effectively than anything I can write in the MSUE Spotlight.
Hear Dr. Sprague talk more on the subject in the following video produced by MSU Agriculture and Natural Resources Communications.
