New study confirms herbicide use changed after adoption of GMO corn and soybean 

But, once again, we are left to wonder whether that’s good or bad.  A new paper was just published in the journal Science Advances that analyzes pesticide use data for farmers in the U.S. between 1998 and 2011. The authors (Edward Perry et al.) are currently agricultural economists at four different universities (Kansas State, Virginia, Michigan State, and […]

Dead plants are probably bad for earthworms

I’ve gotten a number of questions recently about a new study titled “Glyphosate-based herbicides reduce the activity and reproduction of earthworms and lead to increased soil nutrient concentrations” that was recently published in the online journal Scientific Reports. Although the title seems pretty straightforward, there are some flaws in the study design that preclude any broad conclusions from this research. […]

Using ethofumesate when irrigating for emergence

by Andrew Kniss & Abdel Mesbah At a recent meeting in Powell, I was asked how to best use ethofumesate (active ingredient in Nortron SC and other herbicides) in fields that must be furrow irrigated for sugarbeet emergence. This is a difficult question. Ethofumesate (and almost all soil applied herbicides) require soil moisture to be […]

Herbicides for sainfoin

We continue to get quite a few questions about weed control in sainfoin. Unfortunately, there are very few herbicide options currently registered for use in sainfoin (only 6 different active ingredients). We are investigating some additional herbicides in ongoing research trials. Although several herbicides look promising in our trials, these potential options will not be […]
