Fi g.1. Methods of inoculation of PBM in host plan
The seed inoculation technique is the most applied method
(Simon et al. 2011). Advantages and
disadvantages of each inoculation method depend on the tool
accessibility, inoculum and seed type (e.g., size, shape, and
fragility), the presence of inhibitory components in the seed (e.g.,
fungicides, micronutrients, and PBM), and costs (Table 2).
