Blueberry scorch and blueberry shock have been detected in locations in Michigan, the nation's largest blueberry producer. Among these locations is the Trevor Nichols Research Complex, where much of the blueberry research in the state is conducted. Blueberry scorch is vectored by aphids (likely non persistently), although the potential vectors are unclear. Blueberry shock is a pollen borne virus whose spread is mediated by bees. These viruses have yet to be detected in the southeast, but their movement across the US from the Pacific northwest to Michigan raises concern.
