DTN staff reporter Emily Unglesbee has ably covered the dicamba-drift crisis over the past couple of years. Her latest is a detailed, three-part series on Palmer amaranth, “possibly the most aggressive weed American farmers have ever faced” (Unglesbee, 2019a). Palmer amaranth is so scary because of its “spectacular reproductive abilities” and it’s extreme adaptability. This […]

Phosphorous is a key nutrient promoting plant growth, and a standard ingredient in many fertilizer blends. But if too much phosphorous ends up in the region’s watershed, it can wreck havoc on wetlands, streams, and lakes, causing harmful algae blooms (like the extreme cyanobacteria algae blooms in Lake Erie last year) and depletion of dissolved […]

My analysis comparing the evaluation of glyphosate, and glyphosate-based herbicide (GBH) genotoxicity by two key agencies — the U.S. EPA and IARC — was published January 15, 2019 in the peer-reviewed journal Environmental Sciences Europe. The full text of the open-access paper “How did the US EPA and IARC reach diametrically opposed conclusions on the […]

The results are in on one of the first, large-scale studies on organic food consumption and cancer risks and they are significant and encouraging. It is widely recognized we need to do much more in preventing cancer, as opposed to treating it, and this study suggests that organic food may be an important piece of […]

In an experiment conducted in Missouri, researchers have identified Palmer amaranth that is resistant to six herbicides. Amaranthus palmerii is a one tough weed. When full grown, at its base, stalks can match the circumference of a man’s wrist. One plant can set over 400,000 seeds. It has a long history of herbicide resistance, and […]

A research team from the Department of Integrative Biology at the University of Texas in Austin has made an important contribution to the body of research seeking to answer this key question: Is the world’s most heavily used pesticide (glyphosate) contributing to the widespread decline of honeybees and other pollinators? Glyphosate is the #1 herbicide […]

Does the excerpt below from the September 10th issue of Politico’s Morning Agriculture e-newsletter sound familiar? It echoes sentiments on Hygeia in an “Endnote” to our August 20, 2018 post on the Lee Johnson verdict and award, which states — Endnote: The first half of August 2018 will go down in the history of pesticide use and regulation […]

Herbicide-resistant weeds are a common topic around here, so we were interested in this new science out of Argentina identifying a new “superweed” resistant to glyphosate, dicamba, and 2,4-D. Plus, the researchers learned more about the mechanism of herbicide resistance in one of the most common weed families – the Amaranths (Amaranthus species). Farmers throughout the croplands of the […]
