Growers facing high blackgrass dormancy this season are being encouraged to extend the application of residual chemistry by using ethofumesate in post-emergence sprays, according to the latest advice from UPL. Charlotte Cunningham reports. Although pre-emergence chemistry plays a vital role in controlling blackgrass, due to a predicted extended emergence period, further support may be needed to effectively reduce populations, according to UPL. “Ethofumesate, active ingredient of Xerton, is applied to winter wheat from two to six leaves of the crop,” said Rob Adamson, technical support for UPL UK & IE. “It’s compatible with flufenacet plus diflufenican mixtures such as Reliance, as well as iodosulfuron plus mesosulfuron mixtures, such as Atlantis WG.” Target site resistance According to Rob, post emergence residual choice is even more critical when there is acetolactate synthase (ALS) target site resistance, as alternative strategies will be needed. “There’s no known resistance to ethofumesate in blackgrass, which means that this provides a valuable alternative mode of action in the residual stack. “This is because it belongs to the benzofuran chemical family and its mode of action is similar to that of Avadex, which works by preventing lipid synthesis rather than acetyl CoA carboxylase (ACCase) inhibition.” Flufenacet is regarded…
