FIG 3.

Relative isolation frequency (%) of fungal pathogens involved in young grapevine decline from grafted plants treated with different endophytic and rhizosphere actinobacteria with respect to untreated plants. A value of 100 was arbitrarily assigned to the total number of fungal pathogens of a particular species (P. chlamydospora or P. minimum) or Dactylonectria sp.-Ilyonectria sp. group analyzed once the plants had been removed from the field. The relative frequency for each type of pathogen analyzed in the plants treated with the different actinobacteria was calculated as a percentage (%) compared against the value of 100 assigned to the control plants. Data shown correspond to the average of 3 batches of 25 plants in 3 experimental nurseries (2013, 2014, and 2015 growing seasons).
