Active ingredient Trifluralin Alpha, Alpha, Alpha-Trifluoro-2,6-Dinitro-N,N-DIPROPYL-P-Toluidine (C13H16F3N3O4) Called Scott's and the gals I talked with muddled through the label and were very confused as I am also. Can't be used after transplant, can be used up to 10 weeks prior to planting up to 1 day prior to transplanting. So what's the difference between 1 day prior to transplant and after transplant? It isn't going to dissipate in 24 hours. My son used this product last year 2 or 3 times in his vegetable garden after the plants were established. He grows squash, beans, chiles, tomatoes, etc. He had a huge harvest. Now what is the deal on this stuff? What is it really and will it harm my plants? It doesn't hurt bees. Mary-Anne
