| Judul Artikel | PENEKANAN DUA MIKROBA ANTAGONIS TERHADAP PENYAKIT LAYU FUSARIUM GLADIOL DI LOKAWISATA BATURADEN (Supression of Two Antagonistic Microbes On Gladiolus Fusarium Wilt at Lokawisata Baturaden) |
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui: 1) Antagonis yang paling efektif dalam penekanan penyakit layu fusarium gladiol, 2) Pengaruh gabungan dua antagonis terhadap penekanan penyaakit layu fusarium gladiol, dan 3) Adanya pengaruh terhadap pertumbuhan dan hasil tanaman. Penelitian ini dilaksanakan di Laboratorium Perlindungan Tanaman, Fakultas Pertanian, Universitas Jenderal Soedirman dan Taman Bunga Lokawisata Baturaden, Kabupaten Banyumas, Jawa Tengah pada ketinggian tempat 650 meter dpl, dari bulan Juli - Agustus 2012. Rancangan yang digunakan adalah RAK (Rancangan Acak Kelompok) terdiri dari 5 perlakuan dan diulang 5 kali. Perlakuan yang dicoba meliputi: Kontrol, Fungisida Benomil 5 %, Trichoderma harzianum, Pseudomonas fluorescens P60, Gabungan T. harzianum dan P. fluorescens P60. Variabel yang diamati adalah masa inkubasi, intensitas penyakit, laju infeksi, populasi akhir P. fluorescens P60, T. harzianum, dan F. oxysporum, panjang tanaman, jumlah daun, bobot basah tanaman, bobot basah tajuk, bobot basah akar, rasio tajuk, dan pengkelasan dan standar mutu. Hasil penelitian belum menunjukkan penekanan penyakit layu fusarium gladiol yang nyata dari antagonis T. harzianum dan P. fluorescens P60. T. harzianum cenderung lebih efektif menekan penyakit layu fusarium gladiol terhadap intensitas penyakit, masa inkubasi, dan populasi akhir, masing-masing sebesar 79,64 %; 1,08 hsi; dan 6x106 spora/g tanah. Gabungan T. harzianum dan P. fluorescens P60 mampu menekan masa inkubasi, intensitas penyakit, dan populasi akhir patogen masing-masing sebesar 0,93 hsi; 58,38 %; dan 1x107 spora/g tanah. Perlakuan tidak memberikan pengaruh nyata terhadap pertumbuhan dan hasil tanaman. |
| Abtrak (Bhs. Inggris) | This research aimed at knowing: 1) the most effective antagonist in controling the disease, 2)the effects of two antagonists on suppression of the disease, and 3) the effect the antagonists on growth and yield. This research was caried out at the Laboratory of Plant Protection, Faculty of Agriculture, Jeneral Soedriman University and the Lokawisata Flower Garden, Baturaden, Banyumas Regency, Central Java at 650 m above sea level, from July to December 2012. Randomized Block Design was used consisted of 5 treatments and 5 replicates. The treatments tested were: Control, benomil 5%, T. harzianum, P. fluorescens P60, and Combination of T. harzianum and P. fluorescens P60. Variables observed were incubation period, disease intensity,infection rate,number of late population density of both antagonist and pathogen, length plants, number of leaves, fresh and dry weigth shoot, weigth corms with root, classification and quality standart. Result of the research showed that T. harzianum tend to be more effective in suppression igh and dry weight of shoots, fresh weight bulb w of Gladiolus fusarium wilt with the disease intensity, the disease incubation period of pathogen; and late populations of pathogen, each 79,64 %; 1,08 day after inoculation; and 6x106 spores/soil gram. The combinations of T. harzianum and P. fluorescens P60 could suppress the disease incubation period of pathogen to 0,93 day after inoculation; 58,38 %; and 1x107 spores/soil gram. However, the application of treatment has not been able to give significant effect on suppression of disease, growth, and yield. |
