Dual Magnum registered for pumpkins
Editor’s note: This article is from the archives of the MSU Crop Advisory Team Alerts. Check the label of any pesticide referenced to ensure your use is included.
The United States EPA has approved a label for use of Dual Magnum on pumpkins. It is a supplemental label, which is part of the regular Section 3 label. This means that it is not an indemnified label needing special record keeping.
The label allows application of Dual Magnum at 1.0-1.33 pt per acre before the crop and weeds emerge. It should be applied to the areas between the rows and not directly over the crop row. This is to avoid crop injury as the plants emerge. The label mentions broadcast applications and explains the risk for use in that manner, but does not completely exclude it. In my experience, there is very little risk for use of Dual Magnum as a broadcast spray after seeding pumpkins, and also winter squash, which are not on this label. We may be able to obtain a Section 24c (SLN) state label for winter squash in the future.
