Grace from Eugene, Or writes,
My husband sprayed trumpet vines 3 -4 ft from grapes with Crossbow, how can I stop it from getting yellow and wilting?
I noticed the yellow leaves are more under and not on top of the grape vines
As long as Crossbow is not applied directly to the grapes or the drift did not contact the grapes that would not be the cause of the yellow and wilting leaves. It would be best to further examine the grape vines to confirm if a disease or other issue could be the cause.
