my grapes are sick!
Hi I have a couple grape vines for kitchen use and one of them I'm having problems with. I have pics of some of the infected leaves. last year I lost all my grapes. this year so far I have a lot of buds but the leaves are browning and curling. It seems to start at the edges and on the new growth. I would like to take care of it if I can. I think it's a concord variety grape if that helps. I would appreciate any help you can give me!
I wonder if the canes were damaged by cold temperatures during the winter months. Healthy canes should be more grayish. Yours look more blackish in the photos.
There may have also some herbicide drift damage. New leaves do not look right. You might want to take a sample to Union County Extension office for more information. Grapevines also need to be sprayed every 7-10 days for disease and insect control. Refer to OSU Extension bulletin 780 for more information.
