| Abstrak (Bhs. Indonesia) | Penelitian bertujuan mengetahui antagonisme dan daya simpan formula butiran Pseudomonas fluorescens P60, pengaruh aplikasi formula butiran P. fluorescens P60 terhadap penyakit layu bakteri dan pertumbuhan tanaman tomat in planta. Penelitian dilaksanakan di Laboratorium Perlindungan Tanaman dan Screenhouse Fakultas Pertanian Universitas Jenderal Soedirman dari bulan Oktober 2018 sampai Maret 2019. Penelitian terdiri dari dua tahap yaitu in vitro dan in planta. Penelitian in vitro meliputi pengujian antagonisme dan daya simpan formula butiran P. fluorescens P60. Penelitian in planta menggunakan Rancangan Acak Kelompok dengan enam perlakuan dan lima ulangan. Perlakuan yang dicoba yaitu R. solanacearum + tanpa butiran, R. solanacearum + 1, 5, 10, dan 15 g butiran serta bakterisida (Agrimycin sulfat 20%). Variabel yang diamati meliputi populasi bakteri dalam formula butiran, zona bening, masa inkubasi, kejadian penyakit, intensitas penyakit, nilai Area Under Disease Progress Curve (AUDPC), tinggi tanaman, panjang akar, dan bobot segar tanaman. Hasil penelitian in vitro menunjukkan formula butiran hingga minggu ke-10 masih mempunyai aktivitas antagonisme yang baik dan populasi P. fluorescens P60 yang tinggi. Penelitian in planta menunjukkan perlakuan formula butiran P. fluorescens P60 sebanyak 1, 5, 10, dan 15 g, serta bakterisida, 1) efektif menekan perkembangan penyakit layu bakteri, yaitu mampu menunda masa inkubasi antara 22,77-26,25%, menurunkan kejadian penyakit antara 60-85%, menurunkan intensitas penyakit antara 65-85%, menurunkan nilai AUDPC antara 75,69-86,11%, 2) meningkatkan kandungan senyawa fenol yaitu saponin, tanin, dan glikosida, 3) mampu meningkatkan tinggi tanaman antara 24,85–36,17% dan bobot segar tanaman antara 46,04–57,13%. |

| Abtrak (Bhs. Inggris) | This research aimed to study the antagonism and shelf life of Pseudomonas fluorescens P60, the effect of granular formulation application of P. fluorescens P60 to control bacterial wilt and growth of tomato in planta. The research was conducted at the Plant Protection Laboratory and the screen house, Faculty of Agriculture, Jenderal Soedirman University, from October 2018 to March 2019. The research was consisted of two stages, namely, in vitro and in planta tests. In vitro test include shelf life and antagonism of the granule. Randomized block design was used with six treatments and five replicates for in planta test. The treatments were R. solanacearum without the granule, R. solanacearum + 1, 5, 10, and 15 g the granule, and R. solanacearum + bactericide (Agrimycine sulfate 20%). Variables observed were population of bacteria in the granule, clear zone, incubation period, disease incidence, disease intensity, area under disease progress curve (AUDPC), crop height, root length, and fresh weight of crops. Result of the in vitro test showed that the granular formulation up to 10 weeks still performed good antagonistic activity and a high P. fluorescens P60 population. Result of in planta showed that all the granular formulation and the bactericide 1) Effectively suppressed the disease indicated by lenghtening incubation period of 22.77-26.25%, reducing the disease incidence between 60-85%, decreasing disease intensity between 65%-85%, and decreasing AUDPC value between 75.69-86.11%, 2) increasing phenolic compound (saponins, tannins, and glycosides) content qualitatively, and 3) increasing crop height between 24.85-36.17% and fresh weight between 46.04-57.13%. |
