| Description |
Talc-based formulations of plant growth promoting rhizobacterial strain S2BC-2 (Bacillus atrophaeus) and
strain mixture, S2BC-2 รพ TEPF-Sungal (Burkholderia cepacia), inhibitory to the growth of Fusarium
oxysporum f. sp. gladioli (FOG), were developed for corm dressing and soil application in gladiolus. In
comparison to the individual strain, the strain mixture recorded maximum spike and corm production of
100 and 150%, respectively with less vascular wilt and corm rot incidences of 73.6 and 54.8% reduction
over the pathogen control in greenhouse when inoculated with FOG. Reduction in disease incidence
under greenhouse conditions occurred through induction of defence gene products such as chitinase,
b-1,3-glucanase, peroxidase and polyphenol oxidase. Besides disease suppression, treatment with strain
mixture promoted plant growth in terms of enhanced corm and cormel production and flowering. In
field experiments, the strain mixture recorded less vascular wilt and corm rot incidences of 48.6 and
46.1% mean reduction over the non-bacterised control, and was almost comparable with that of fungicide
(51.5 and 47.1%, respectively). The treatment also recorded increased spike and corm yield with average
increases of 58.3 and 27.4%, respectively, relative to the control.
