The exsperiment was conducted to analysis enzyme activity of  onion plant that induction with rhizoplant indigenous bacteria to control bacterial leaf blight (Xanthomonas axonopodis pv allii). The aim of the exsperiment was analyze defense enzyme activity on onion plant that resistance to bacterial blight disease. The onions was introduction with rhizoplant bacteria and after 14 day planting the onion plant inoculation with Xanthomonas axonopodis pv allii. Enzym activity analyze on 0, 1, 3, 5, 7, 10 and 25 days after inoculation. The result of the exsperiment showed that  activity of 3 enzym  (Perocsidase, Pholyphenol Oksidase and Phenylalanin Lyase) was increase from 0 day  until 25 days after inoculation. Phenylalanin lyase and Polyphenol Oksidase was the highter activity. 

Key words: Bacterial leaf blight, Rhizoplant bacteria, Xanthomonas axonopodis pv allii,
                    Perocsidase, Polyphenol Oksidase, Phenylalanine Lyase
