The 1957 Legislature expanded The Florida Hyacinth Control Program to a Noxious Vegetation Control Program. This made testing of herbicides for the control of other noxious plants necessary. A convenient field test of herbicides was developed. These herbicides were tested using disel oil and/or water as a carrier. The herbicides tested were Atlas "A" (sodium arsenite), Amino Triazole (3 amino-l,2,4-triazol), Aquaherb (orthodichlobezene and aromatic salt), Aqua San (trichlorobenzene and aromatic petroleum distillate), Ammate (ammonium sulfomate), Atlacide-2,4-D (sodium chlorate-2,3-dichoroxyacetic acid), Granulated Chlorea (sodium chlorate, sodium metaborate and 3- (P-chlorophenyl)1, I-dimethylurea), Dowpon or Radapon sodium salt of 2,2 dichloropropionic acid), Esteron (2,4,5-trichlorophenoxyacetic acid, propylene gycol buytol ether ester), HCA (hexachloroacetone), Kuron, propylene glycol butyl ether ester of 2(2-4,5 trichlorophenoxy) propionic acid, M-502 (invert immulsion butoxy ethanol, ester of 2,4-D), Simazin-lOG (2-chloro-4,6-bis- (ethylamino) -S-triazine), TCA (sodium salt of trichloroacetate), Veon-IOO (dimethylamine salt of 2-4 dichlorophenoxyacetic acid-dimethylamine salt-2,4,5-trichlorophenoxyacetic acid), 2,4-D Pellets (iso-octylhexyl) (ester 2,4-D attac1ay granules), 2,4-5T Pellets (iso-octyl ester of 2,4-5T), 2,4-D Ester (isopropyl, 2,4-5T (iso-octyl ester) . Several herbicides were used on separate plots of alligator weed, cattails, maiden cane, Najas, pickerel weed, spatterdock and water lettuce. Preliminary results of these tests indicate an aquaherb and 2,4-D combination, 2,4-5T pellets or M-502 gave some control when used on alligator weed. Kuron, 2,4-D Ester or RCA gave good results on pickerel weed. Dowpon, Radapon or 2,4-D Ester gave excellent results on cattails. M-502 gave good results on water lettuce. None of the herbicides used on Najas or maiden cane gave the desired results, although Dowpon, Radapon and Amino Triazole showed some promise of control on maiden cane. Kuron gave a good indication of control of spatterdock.
