During the 2014 growing season, the University of Tennessee Cotton Variety Testing program was given an opportunity to evaluate several of the new Monsanto Bollgard II® XtendFlex™ cotton varieties. Given the recent de-regulation of this trait, many may find this data of interest. (De-regulation of dicamba applications to these varieties is still pending.) Continue reading

The following is an updated version of an older article … The next 4-5 weeks is the time to consider making a foliar application for aphids in wheat. I’ve discussed the potential value of managing aphids to prevent the spread of barley yellow dwarf virus (BYDV) in a previous article. A late-winter, foliar insecticide application, at least on wheat not having an insecticide seed treatment, has shown a consistent yield benefit in my testing over the last five years (figure below).

This stems from a recent “benefits assessment” released by the EPA (http://www2.epa.gov/pollinator-protection/benefits-neonicotinoid-seed-treatments-soybean-production). This is the first step towards the banning of neonicotinoid seed treatments in soybean, mostly stemming from concerns about how these treatments affect pollinators. My response below in rather lengthy, but I wanted to get on the public record. Continue reading
