Lucerne seed dressed with orthocide (75% captan) and inoculated with Rhizobium meliloti developed into healthy seedlings with normal root nodules, although the fungicide is toxic to R. meliloti in culture. Dressing seeds with orthocide, agrosan-GN (an organomercurial) and fernasan (thiram) after inoculation gave slightly higher lucerne yields than did dressing before inoculation, but not sufficiently to warrant a change in the normal commercial procedure.
