Grape problems.

[Rickster57]

Newbie at this with only 3 vines. Bought in early June this year in 1/2 gallon pots labeled Catawba grape at a local Lowe’s. They have taken off and nearly completely filled the trellis. But there is something eating them up. I know Jap beetle has done a lot but there seems to be a disease causing leaf curling up. I tried fruit tree spray (neem oil) to no avail. Now I’ve sprayed twice with Captan and Malathion. The beetle’s seem to be gone but something is still causing damage to the new leaves as they start to grow. I’ve included some photos. I’m in zone 7a, Southeast Ky.

You should be ok. The sprays should control mildew and rot. One pic is a leaf miner. Not much you can do about that. One pic looks like a mineral issue.

Which mineral could it be?
