Help with vine leaf drama

Hi

I have a small vineyard and have noticed one of my plants appears to be under the weather so to speak. The leaves are not filling out and appear to be curling under some although I dont think its curling disease. Please take a look at the pictures and any help direction would be great.

Note the nice filled out leaves next to the suspect ones

 

Herbicide injury looks similar.
2,4-D damage.

Hi All

Well, I think I have it figured out now and the reply post pretty much sealed it. I believe a spray between the rows leached into the roots below...:(.

I guess chock up to learning

If you are the El Dorado Hills between Sacramento and Placerville - take a good sized sample down to the wine growing division at U.C. Davis. They should be able to tell you with authority. Is Sams still in business? Barb;))

 

With sprays usually the problem is spray drift blowing onto foliage.

 

HI Barb

Yep, thats the plan this week as UCD is on my way to the bay this week..Sams and Costco still there. Mike

 

Aaaaahhh! The good old days of heat, smog and traffic. Costco must be fairly new. barb
