Weed killer may cause yellow leaves on pomegranate

Q: Eleven of my 50 young pomegranate trees have leaves yellowing and dropping off. I water this area once a week by flooding. I sprayed a weed killer, 2, 4-D, near the pomegranates, but I protected each one with plastic to avoid damaging the trees. Where did I go wrong here? If the weed killer is the problem, is there any way to save them?
