Rely 280, a more concentrated formulation of Rely herbicide, is now registered by EPA.
This formulation of Bayer CropScience’s Rely is said to provide an effective desiccation while allowing potatoes additional time to add bulk before digging.
Some chemical desiccants kill vines quickly, stopping tuber bulking prematurely, explains Andy Hurst, Bayer CropScience product manager. Rely 280 works more slowly, mimicking the natural senescence process and allowing tubers seven to 14 days of extra bulking time.
In addition to potato vine desiccation, Rely 280 is labeled for several crop and non-crop uses, including apples, tree nuts, grapes, bushberries, and other berries.
