Paraquat, or gramoxone as it's called now, has always been a restricted use herbicide, as far as i know. Have sprayed many many gallons of it in peach orchards. I believe gramoxone is a watered down version of paraquat. Like most everything else, you pay more for it each year & have to use more per acre to get the same effect. I can remember using guthion, parathion, thiodan & other really effective insecticides that the epa has banned in America, yet other countries still use these chems & then ship their produce here. Epa has no problem with that- has always been run by liberals of course, until recently anyway. Always about the money & they'd sure like to see roundup go extinct- after the deep pockets have been emptied. Hopefully the SC just ended that.
