dc.description.abstractAbstract Potency of Indigenous Endophytic Bacterial Isolates as Biocontrol Agent for Bacteria Bacterial Blight of Rice. An experiment to study the potential of endophytic indigenous bacterial isolates of ICABIOGRAD microbial germplasm collection against bacterial blight (BLB) on rice caused by Xanthomonas oryzae pv. oryzae has been conducted. Results revealed that the bacterial endophytic isolates were slightly reduced the length of BB lesion. The lowest length of BB lesion was obtained when the endophytic indigenous bacteria were sprayed prior the development of the disease, whilst the slower effect was obtained when the endophytic indigenous bacteria were sprayed at 1 week after inoculation (WAI). Spraying the rice leaves with E 65 and E 95 of endophytic bacteria at the bacterial concentration of 10 cfu/ml prior the development of the disease decreased the length of BB lesion by 34.37 and 30.67%, respectively, meanwhile at 4 WAI only isolates E 65 and E 66 reduced the length of BLB lesion by 16.16 and 13.89%, respectively. Abstrak Percobaan telah dilakukan untuk mengkaji potensi keefektifan agen biokontrol isolat bakteri endofitik lokal terhadap penyakit hawar daun bakteri (HDB). Hasil penelitian menunjukkan bahwa aplikasi bakteri endofitik mengurangi panjang gejala penyakit HDB Panjang gejala penyakit HDB terendah diperoleh kalau bakteri endofitik disemprotkan sebelum infeksi terjadi, sementara efek yang lambat terjadi kalau bakteri endofitik disemprotkan setelah terjadi penyakit untuk maksud penyembuhan (kuratif). Saat 1 minggu setelah inokulasi (MSI), bakteri endofitik isolat E 65 dan E 95 pada konsentrasi 10' cfu/ml dapat menekan perkembangan HDB pada padi varietas IR64 berturut-turut sebesar 34,37% and 30,67%, sementara pada 4 MSI, isolat E 65 dan E 66 mampu menekan panjang gejala HDB berturut-turut sebesar 16,16% dan 13,89%.
