Near Richmond, IN | Mark, three or four years ago (maybe more, can't remember) I sprayed First Rate on some giant ragweed and for two summers straight it seemed more like it fertilized them than killed them. Co-op said I had resistant ragweeds. I sprayed some fairly large ragweeds about two weeks ago with 1.5 qt. generic round up and it smoked them pretty good. You might want to check with the co-op or Lloyd about the First Rate resistance first. | |
