The purpose of this study is to find out the type of antagonistic rhizobacteria and their capability in F. acutatum growth suppression on in vitro and in vivo condition. The study was conducted by selecting of rhizobacteria isolated
from Shallot’s rhizosphere which was taken from 4 regions; they were Bantul district (Yogyakarta), Nganjuk (East
Java), Cirebon (West Java) and Brebes (Central Java) district. Characterization was taken based on physiology and
biochemist, PCR based on 16S rRNA and Rep-PCR (BOX-PCR and ERIC-PCR). The in vivo test was carried out by
factorial experiment with 2 trials using completelly randomized design i.e., 1) soaking shallot seeds into rhizobacteria
suspension for 1 hour before planting and 2) watering plants with rhizobacteria suspension in once 2 weeks.
