Abstract

Gross autoradiography showed that translocation of C14-labeled 3-amino-1,2,4-triazole (amitrole) from the leaf of quackgrass (Agropyron repens (L.) Beauv.) was retarded over 12 hr by ammonium thiocyanate applied as a spray or as a spot. While considerable export of C14 from the treated leaf occurred during 12, 24, and 96 hr after C14-amitrole was applied, C14-NH4SCN as a tracer was largely restricted to the treated leaf over the first 24 hr and showed only slight export over 96 hr. It was concluded that the synergistic effect of NH4SCN on amitrole is exerted in the treated areas and not at the ultimate site of amitrole action.
