Talking Biotech: How will dicamba herbicide-resistant GMO crops fare after contamination fiasco?

Over the last two years, we have heard reports of herbicide damage to Midwestern crops, bearing the signatures of damage from dicamba. Dicamba is an older herbicide, an auxin analog that mimics a plant hormone associated with growth and cell division. This herbicide was made relevant again in soybeans and cotton, which have been genetically engineered to be dicamba-resistant, needed because of the increase in glyphosate-resistant weeds. Since the deployment of these seeds, farmers have seen evidence of herbicide damage, opening endless finger pointing and legal gyrations. University extension experts have weighed in. Companies deny wrongdoing. How to sort this out? This episode features guest Karen Corrigan, an independent agronomist that provides a boots-on-the-ground assessment of the problem, how it happens, and what is likely to occur in the next steps.
