Disease symptoms on whole cassava plants following transmission by chip bud graft inoculations. (A) CMD symptoms on cultivar 60444 – non-inoculated plant (left) and plant grafted with a bud carrying EACMV-K201 nine weeks after graft initiation (right) (B and D) healthy non-inoculated control plants of cultivars TME204 and 60444 at 10 weeks of age and (C and E) CBSD symptoms on leaves of cultivars TME204 and 60444 at six weeks after grafting with a chip bud carrying CBSV. Leaf symptoms are restricted to leaves within a zone of 4–6 nodes situated 10–12 nodes above the graft site.
