Looking for Grape Scions Resistant to Black Rot

Asked March 5, 2018, 12:53 PM EST

Losing a 20 year battle with Black Rot on two Concord and two Niagara grape vines. Roots still seem good, so I want to graft on the most resistant scions there are and that way I won't have to waste good roots. Do you know where to find a Maryland vineyard that could sell me 4 cuttings that resist anthracnose?

Black rot can be a very difficult disease to combat for sure. But a black rot resistant scion such as you are looking for does not exist to our knowledge. Please see our information on grapes and also the information on preventative spraying for black rot https://pubs.ext.vt.edu/content/dam/pubs_ext_vt_edu/456/456-018/section3-home-fruit.pdf

One note about applying fungicides it is best to apply them before a rain event (allowing sufficient time for them to dry) so the
leaves are protected before the rain.
