Agent Orange is Round-Up. Same chemical - only difference is the toxicity of the PCB by products. When they manufacture this plant killer there are some very nasty by products. If the level is too high in these by products it is not allowed to be sold in the US. So it goes to other places.

The thing that made Agent Orange/Round-Up so bad is the high levels of carcinogenic material in them that was used in Viet Nam and other places. Really messes you up. Take a look at what makes up Agent Orange and then look at Round-Up - same stuff.
