After a U.S. District Court vacated the registrations of certain dicamba herbicides, growers must find new ways to manage their weed control through a 3 step process.
The Wisconsin Cropping Systems Weed Science program has conducted several research trials investigating post-emergence weed control in XtendFlex soybean systems (dicamba-, glufosinate- and glyphosate-resistant soybean) without OTT applications of dicamba.
A federal court in Arizona has vacated the Environmental Protection Agency's (EPA) 2020 approvals of dicamba-based herbicides sold by Bayer (XtendiMax), BASF (Engenia) and Syngenta (Tavium).
The study says the data show a rapid falling-off of glyphosate effectiveness against seven major weeds after the first couple of years. The authors conclude that intensive use of any one weedkiller like glyphosate year-after-year serves to speed up evolution in weeds to resist it.
In the Spring, growers may experience challenges when controlling winter annuals weeds or terminating cover crops with glyphosate-based burndown herbicide programs, specifically when glyphosate is sprayed in cool, cloudy weather conditions.
Critics allege the lawsuit is a way to ‘relitigate’ responsibility for millions of acres of damage to crops and natural areas across the Midwest and South.
Bayer is suing four farmers in the Bootheel of Missouri for illegally spraying older versions of dicamba on its genetically-engineered soybeans, as well as doing so after the state’s cutoff date for spraying the herbicide.
With spring soybean planting just a month and half away for many farmers, the U.S. EPA has released new dicamba usage restrictions for the 2023 growing season that apply only to in-season dicamba use in soybeans.
Localized populations of these species found on headlands or field margins likely represent a new introduction. Populations that are distributed throughout fields are likely a sign that these species have gone undetected for more than one year.
This year, ISU Extension field agronomists, commercial agronomists and other stakeholders in several areas of the state have observed a high percentage of non-dicamba tolerant soybeans showing injury symptoms characteristic of dicamba.
