title: Translocation of Streptomycin from Coleus Leaves and Its Effect on Rhizosphere Bacteria.
abstract: Autoradiographs showed that when streptomycin is applied to leaves of coleus plants (1000 to 3600 micrograms per plant) the antibiotic or some by-product is translocated laterally and downward. The translocated material does not alter rhizosphere microorganisms quantitatively. Gram-negative rhizosphere bacteria, however , are suppressed through the 8th day after treatment.
