I have a small vineyard of Concord and Niagara grapes that were subject to what I think is 2,4-D damage . It was in the process of setting fruit when it was subject to two days of 60 mile an hour winds so I am not sure where the drift came from. There are a lot of elongated clusters that are aborting and curled upward leaves. They are now setting on new growth that have clusters on them and they look healthy. My question is should I prune off the damaged vines or leave them alone and just let them grow? Thanks Jeff
