This could have been because more herbicide was stored in tubers at Inkster and injury was manifested more in Inkster than Oakes. While at Oakes more herbicide was activated within the leaves causing the current season losses. The wide range of results indicate great variability in response to herbicide expo- sure. There is some good news on the new for- mulations and labels to protect potato growers. The new formulations of dicam- ba, Xtendimax and Engenia, have made dicamba much less volatile. Additionally, there is language in the label that says do not apply when wind is blowing in the direction of neighboring specialty crops, including potatoes. There is a large list of things applicators can and cannot do that is written in these labels to ensure a prop- er treatment. (Go to http://www .cdms. net/Label-Database to search for current labels). What can potato growers do to protect their potato fields? Some ideas are: talk to neighbors and let them know you have potatoes and they are sensitive to dicamba, plant borders around fields for added pro- tection, train employees about the sensi- tivity to dicamba and signs of dicamba, scout field regularly and walk field edges, place signs around fields indicating they are sensitive to dicamba and list your potato fields on the sensitive area data- base (for North Dakota go to https://beemap.ndda .nd.gov/ and for Minnesota go to http://www.fieldwatch. com/). Applicators are required to consult sensitive crop registries before spraying the new dicamba formulations. Allowing applicators to be aware of potatoes on these online sensitive crop registries will help prevent off-target injury and down- wind issues.
