This article is the first in a series reviewing unique or updated label requirements for key herbicides. Certain dicamba products were approved for post-emergence control of weeds in Xtend Soybean in 2017. The labels for these products include some additional requirements intended to reduce the potential for non-target injury caused by herbicide drift.
Face-to-face dicamba application training opportunities, sponsored by agrichemical companies, are available at various locations throughout Kansas in the coming months. Dates and locations are listed in this article from Sarah Lancaster, Weed Science Extension Specialist.
For producers that intend to use Xtend cotton or soybean in 2020, you will need to have an additional dicamba-specific certification to apply dicamba-containing products labeled for use in these crops. Online training is available.
On June 3, the Ninth Circuit Court of Appeals in San Francisco issued a decision that nullifies the current labels for Engenia, FeXapan, and XtendiMax herbicides. Weed Science Specialist Sarah Lancaster discusses this decision and what is known at this point.
This article briefly outlines new information from the EPA concerning the cancellation order of dicamba made by the Ninth Circuit Court of Appeals. More information will be coming as it becomes available.
On Wednesday, June 10, the Kansas Department of Agriculture provided clarification of the impact of the EPA cancellation order for Engenia, FeXapan, and XtendiMax product labels.
It is that time of year again for post-emergent applications of Engenia, Fexapan, and Xtendimax on dicamba-resistant soybeans. In light of the recent court ruling, it is vital that application restrictions are followed closely to prevent non-target dicamba injury to conventional, Enlist, and Liberty Link soybeans.
XtendFlex soybeans gained approval for use in the U.S. for the 2021 season. XtendFlex soybeans allow over-the-top application of glyphosate, specific dicamba-containing herbicides, and glufosinate (Liberty).
On October 27, 2020, the EPA issued approval for three labels for over-the-top dicamba application. The labels will be effective until 2025. More details are included in this article.
The article has been updated slightly from the original version published on October 30. Stay up -to-date on the recent EPA ruling concerning certain over-the-top dicamba products.
Game theory is an economic tool that can be used to understand decision making in circumstances where uncertainty exists. This article examines the outcomes when applying game theory to farmers' decisions related to soybean weed management.
This article covers frequently asked questions associated with paraquat and dicamba trainings for the state of Kansas in 2021.
Don't forget that the 2021 labels for over-the-top applications of herbicides containing dicamba have cut-off dates. For soybeans, this cut-off is just around the corner. Applications to cotton have a few weeks longer. Read more in this short article from Sarah Lancaster.
Anyone spraying XtendiMax, Engenia, or Tavium is required to have training each year prior to using these products. These products are restricted use pesticides and can only be applied by certified applicators.
Farmers planning to apply XtendiMax, Engenia, or Tavium to their dicamba-resistant soybean have about two weeks remaining to make those herbicide applications. These are the only dicamba-containing products labeled for over-the-top use in dicamba-resistant soybean and cotton. The last day these products can legally be applied to soybean is June 30. The cut-off date for cotton is July 30.
