Should I be worried about this vine?

[sparkplug]

I planted 3 vines this year for the first time.

Two seem perfectly OK but I have one which has a few spots and a few malformed leaves. I'm not sure if this is something to be worried about?

I did have some whitefly earlier in the year but they have now been dealt with - I don't know if it could be related.

Any ideas / opinions / advice greatly appreciated

Thanks

Looks like some form of fungal infection, you could try googling images of vine leaf problems to narrow it down.

I would pick off the worst leaves and pick up all the leaves in autumn and burn, to get rid of any spores. If signs show next year I'd consider something like Bordeaux mix.

Can vines suffer from black spot like roses,ive had many roses with blackspot.

The bottom leaf with the brown edges is definately mildew. Not sure about the dark spots but it's probably mildew too & the curled deformed leaves have probably been sucked by some critters such as thrips. I don't think you have much to worry about & vine leaves at this time of year can look pretty tattered & stained anyway. Clear up all the fallen leaves later on
If you want to treat the mildew, next year when the leaves start to grow spray with Bordeaux mixture (copper sulphate & lime) & respray everytime the rain washes it off. There are other fungicides you can use but I prefer the "Bordo mix" as it's non toxic for us & the enviroment. It's even allowed to be used on organic crops.
What variety(s) have you planted ?

Not sure what the proper name is but it looks definitely like grape vine blackspot. It's very common in newly planted vines and particularly common after wet springs. I had it on a vine I planted in my place in Greece as I didn't want it to infect my mature vines I pulled it up and burnt it my neighbour then treated the mature vine with copper sulphate ( I think). All this was frankly a bit over the top. I can't remember what the treatment is now but I'm sure a google search on the wine sites will give the cure. It's a fungal infection which is transmitted by wind and insects so you will need to treat the other vines as well. Certain types are more susceptible than others. I am in no way an expert but I would act quickly.

Just had a looksee at black spot (anthracnose) & looking again at the little dots on your leaves it could well be. It can also distort the leaves. There's nothing you can do now but next spring, it might be a good idea to start treating all 3 vines with a specific fungicide. especially as it doesn't look too far advanced & you won't be eating grapes for another few years yet. Don't forget the mildew either. Always clear away dead fallen leaves & burn or bin them, don't put them on the compost heap.
There's a lot of work & worry in growing grape vines but when it all comes together,............yummy

Well spotted Gaudette, no pun intended.

Thanks to all - will get some appropriate fungicide and treat all 3 as suggested.

Might not have had grapes yet, but did stuff a few leaves with brie and crushed almonds and black pepper and did them on the BBQ - yum!
