Dear Dr. McDonald:
The trees and grape vines I inspected on your property are showing typical symptoms of phenoxy herbicide damage. The leaves are curled, twisted, and distorted. Although I cannot tell with certainty which phenoxy herbicide was involved, I strongly suspect it was 2, 4-D, or some formulation containing 2, 4-D. I verified my diagnosis with th Agronomist from our local extension center.
2, 4-D is a commonly used broadleaf herbicide which tends to volatilize once it has been applied. The damage I observed on your trees and specially your grapes may have been caused by spray drift, but is more likely to have been caused by the drift of volatilized herbicide after it was applied. Grapes are so susceptible to phenoxy herbicides that they can be damaged by herbicides sprayed hundreds of yards away.
There are other, less volatile which are labeled for use on thistles and other broadleaf weeds. The University of Missouri Extension Service would be best able to help you and your neighbors select weed control methods which won't harm your grapes and your trees. You may wish to contasct Elbert Turner, Extension Agronomist.
Sincerely,Lexicon
