Brandon:

That could well be too much spray. But whatever it doesn't look serious.

Thanks for your help!

Any herbicide (weed killer) used *anywhere* in the vicinity, including somewhere you consider too far away to affect the grapes?

i think you just have new father paranoia ...

crimminey.. its august.. leaves look battered ... and there is nothing to do about it ...

and frankly.. your leaves do NOT look battered ... and i see little or no JB damage ....

put down the sprayer.. and walk away ...

your new vines.. are growing roots .. so as to mature .. and eventually fruit... they .. nor i .. really care about their leaves ...

frankly.. you need to take a course on IPM this winter ... contact your local extension office and see if a class is offered in your area .... otherwise.. i fear you are on the road to excessive chemical usage leading to pollution ... BEEN THERE ... DONE THAT .... do as i say.. not as i used to do ...

ps: same goes for the lawn.. if jean is right ....

Here is a link that might be useful: i used to be the same way ....
