The spray inoculation and F113rifpcb ⁄seed co-encapsulation techniques were equally effective at establishing high
inoculum counts on the roots of plants, resulting in c.

root tissue. Bashan et al. (2002) found similar colonization levels when microalginate beads were used
to inoculate tomato and wheat plants with the PGP strain
A. brasilense. However, Young et al. (2006) found that
encapsulation of their inoculum leads to enhanced plant
root colonization 10 compared
with free cell inoculation 10
