Abstract

This study was conducted for tenth month in laboratory and greenhouse of Plant protection
Department of Agriculture Faculty Jember university. This research was coonducted by two step in
vitro including identification and screening in laboratory,and in vivo including induce systemic
resistant and leaf interaction of antagonist against patogen. The result show that activities of
fluorescent pseudomonad in vitro against C. nicotianae was by production antibiotic, proteases and
siderophore. Antagonistic invitro was effective under 20-30OC temperatures. Influence of iron
concentration at 5, 50 and 100 μM was affect on antagonist by siderophore, more high concentration
less ability to suppress C. nicotianae growth. In greenhouse test, all isolate was shown ability to
control C. nicotianae by induce plant resistant and by antibiosis activities.
