Something weird is going on with some of my cab vines.

I apologize for not having any photos right now will update with some tomorrow but I noticed that about 20 cab vines in my vineyard have circular red dots all over the majority of there leaves and the leaves have red veins and a pale sort of yellowish color they are also dropping a lot of leaves and I don’t have much experience with dealing with grapevine diseases or nutrient deficiency and don’t really have anywhere local to get the vines tested so I was hoping someone might have a idea what’s going on before I try and find a place that can test for nutrient deficiency and etc and spend the money.

Thanks

I don't have any idea what's going on but that sure is one hell of a sentence.

Not to interrupt a thread but I have a problem too!? I have a few Concorde vines where for the 2nd year in a row have refused to turn colors? In the past they have always changed from green to dark dark purple but now just stay green?

For about $25 you can have your leaves tested for minerals. I use Agsource in Wisconsin, they have a website that explains how to mail the leaves. Usually about a three day turnaround

Thanks, I have black Munuka and muscadine planted right beside them with no problems. The concord has beautiful big green bunches they just don’t change any longer!
