First Report of Twig Dieback Caused by on Highbush Blueberry in the Continental United States.

Highbush blueberry (Vaccinium corymbosum) is an important fruit crop for pick-your-own agritourism farms in the Midwest. Declining or diseased plants are a major concern for pick-your-own farms, as consumers prioritize healthy plants and organic practices (Norby and Retallick 2012). In August 2023, leaf spot and dieback symptoms were observed sporadically on the current year's growth throughout an organic berry agritourism farm in Eastern Iowa.
