The inhibitory action of the five biocontrol strains on R. stolonifer
VBAM1 was also evidentially proved when clear mycelial disintegration
and damage was observed in scanning electron
micrographs of the pathogen upon treatment with either B. cenocepacia
VBC7, P. poae VBK1 or three strains of L. lactis subsp. lactis
(Fig. 7B–F) compared to its untreated control (Fig. 7A) where intact
mycelial structures were observed. Such degradation was probably
due to chitinase or b-glucanase as observed in other biocontrol
organisms
