One question that bounces around in my head is what happens after you spray? Does the 2,4-D wash into streams or water table? I remember when Roundup first came up it was supposed to "bind to the soil particles", this doesn't make me overly comfortable, but perhaps it prevents it from washing into streams or the water table.

It's been a long time since my college days, but if I remember correctly, 2,4-D degrades pretty rapidly in the environment - pretty well played out after about 21 days - UV rays degrade it pretty rapidly.
Its 'badder big brother', 2,4,5-T(Agent Orange), on the other hand, persists for quite a while. I've got a small 16 oz can of 2,4,5-T that I found in the basement when we moved my mother-in-law out of her home several years back. I'm saving it for use as a stump treatment in the event that any Ailanthus, wisteria, or sweetgums ever show up here on the place - though I'll probably use Pathway(Tordon)RTU first.

As to the oral-route preventing allergies, that seems to go against part of what allergists are saying about children and too early exposure to certain allergans like peanuts.
I'm not an immunologist by training, so can't comment on all the nuances of allergy development. There may be some significant differences in the composition of the peanut allergen and urushiol.
