TY - JOUR AU - Addy, Hardian Susilo PY - 2012/12/05 TI - Aktivitas Pseudomonas Pendar Fluor Dalam Mengendalikan Penyebab Penyakit Patik (Cercospora nicotianae) Pada Tembakau JF - Jurnal Pengendalian Hayati; Vol 1 No 2 (2008) KW - fluorescent pseudomonads, C. nicotianae, Biocontrol Activity N2 - 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. UR - https://jurnal.unej.ac.id/index.php/JPH/article/view/25
