As before, each company will maintain a website that lists approved hooded/shielded sprayers, spray nozzles, and tank-mix partners. Those websites will be:
                XtendiMax): www.xtendimaxapplicationrequirements.com

                Engenia: www.engeniatankmix.com

                Tavium: www.taviumtankmix.com

The EPA also issued a clarification limiting the use of Special Local Needs (Section 24(c)) labels to add additional state-specific restrictions. At this time, it is unclear if the Kansas Department of Agriculture will seek any modifications to the federal label.

In a recent survey, 56% of producers indicated they will plant dicamba-resistant soybeans in 2021, down from 78% who reported planting dicamba-resistant soybeans in 2020. A potential increase in non-dicamba-tolerant soybeans for 2021 highlights the need for extra care when making in-crop dicamba applications.
