dc.description | Anyelir (Dianthus caryophillus L.) merupakan salah satu jenis tanaman hias yang mempunyai nilai ekonomi tinggi. Penyakit utama yang menyerang tanaman ini ialah layu Fusarium yang disebabkan oleh Fusarium oxysporum f. sp. dianthi dapat menurunkan kualitas dan kuantitas produksi tanaman sekitar 20-60%. Pengendalian yang selama ini dilakukan oleh petani bertumpu pada penggunaan pestisida kimia sintetik. Namun penggunaan bahan kimia tersebut tidak mampu mengeradikasi patogen secara sempurna, terutama pada lapisan tanah yang agak dalam. Salah satu cara pengendalian berwawasan lingkungan ialah menggunakan musuh alami. Penelitian ini dilaksanakan di Laboratorium dan Rumah Kaca Balai Penelitian Tanaman Hias (1.100 m dpl.), sejak Mei sampai Desember 2009. Penelitian bertujuan mengetahui pengaruh Bacillus subtilis dan Pseudomonas fluorescens yang diformulasi dalam bentuk biopestisida organik cair dalam pengendalian layu Fusarium pada tanaman anyelir. Rancangan yang digunakan ialah acak kelompok dengan 10 perlakuan, yaitu 10% ekstrak kascing + 10% molase + B. subtilils + P. fluarescens (BP) dan 10% ekstrak pupuk kandang kuda + 10% molase + BP masing-masing konsentrasi 0,1, 0,3, 0,5, dan 0,7%, dazomet 0,2%, serta kontrol (air ledeng), dengan empat ulangan. Hasil penelitian menunjukkan bahwa populasi bakteri antagonis setelah dilakukan proses fermentasi selama 3 minggu, meningkat dibandingkan sebelum fermentasi. Rerata populasi awal sebelum fermentasi bakteri antagonis 107-109 cfu/ml meningkat menjadi 1010-1012 cfu/ml pada 3 minggu setelah fermentasi. Populasi kedua agens biokontrol tersebut setelah penyimpanan selama 2 bulan cenderung stabil berkisar antara 1010-1011 cfu/ml. Perlakuan B. subtilis dan P. fluorescens yang disuspensikan ke dalam ekstrak kascing + molase pada taraf konsentrasi 0,5% kemudian difermentasikan dalam biofermentor selama 3 minggu secara konsisten dapat menekan serangan F. oxysporum f. sp. dianthi pada anyelir. Implikasi hasil penelitian ini dapat meningkatkan daya saing komoditas tanaman hias melalui pemanfaatan sumber daya alam nasional secara optimal berkelanjutan untuk mendukung industri tanaman hias yang berdaya saing tinggi.Carnation (Dianthus caryophillus L.) is one of the most economically important cut flowers in Indonesia. The crops is commonly cultivated in the highland areas of the country. Cultivations of the crops in the production center areas have faced various problems, especially wilt disease caused by Fusarium oxysporum f. sp. dianthi as the most important one. Based on the field observation it is known that the disease could reduce plant production and its yield quality up to 20-60%. To control the disease, farmers usually use a synthetic chemical pesticides. However the control measures are not sufficiently effective to overcome the diseases problems. Therefore, an alternative control measures which are more environmentally friendly is necessary. The use of biocontrol agents is nowdays bring popular to be recommended to control the disease. A study on the control of fusarial wilt disease on carnation was carried out in the Laboratory and Glasshouse of Indonesian Ornamental Crops Research Institute (1,100 m asl.) from May to December 2009, using Bacillus subtilis and Pseudomonas fluorescens formulated in the liquid organic pesticide. The study was arranged in a randomized block design, with 10 treatments i.e. 10% vermi compost + 10% molase + BP and 10% horse manure + 10% molase + BP consentration 0.1, 0.3, 0.5, 0.7% resfectively, dazomet 0,2% and control with four replications. The results showed that population of antagonistic bacterial was increased from 107-109 to 1010-1012 cfu/ml after 3 weeks fermentation in the organic carrier. The population of two antagonistic bacteria was likely stable on 1010-1011 cfu/ml after storing 2 months. The treatments of B. subtilis and P. fluorescens suspended in the vermi compost extract and molases on the concentration level of 0.5% and formulated in the biofermentor for 3 weeks were consistenly effective in reducing Fusarium wilt on carnation. The implication of research results could be increase commodity competitive ability of ornamental plants by using national nature resource on a continuity for support the ornamental plants industry with high competitiveness. | en-US |
