Chemical Damage...permanent or not?

update: Stan's family thinks chemical guy was being overly optimistic about the herbicide drift from the Atrazine/Halex Gt combo...they came over last night to look at the garden and don't see how it will be OK. They pointed to weeds in the field close to the garden that hadn't even died yet. So...time will tell. Specifically, we should know by June 16 or so. This up and down is really messing with my sanity this week.
