Abstract

The herbicide 2,4,5-T [(2,4,5-trichlorophenoxy) acetic acid], at concentrations of 10 −4 and 10 −6 M in nutrient media, was more inhibitory to the growth of soybean ( Glycine max (L.) Merr. “Acme”) tissue culture than dicamba (3,6-dichloro- o -anisic acid) or picloram (4-amino-3,5,6-trichloropicolinic acid). Dicamba (10 −6 and 10 −8 M) and 2,4,5-T (10 −8 M) stimulated growth of soybean tissue. Mixing equimolar solutions of 2,4,5-T + dicamba, 2,4,5-T + picloram, or picloram + dicamba at 10 −4 , 10 −6 , and 10 −8 M did not increase phytotoxicity over that of the most phytotoxic herbicide of the pair.
