Pengendalian Layu Fusarium Menggunakan Mikrobe Antagonis dan Tanaman Resisten pada Lili

Lili merupakan tanaman hias penting dan bernilai ekonomi tinggi. Budidaya lili di Indonesia menghadapi kendala utama yaitu penyakit layu Fusarium. Aplikasi bahan kimia sintetik untuk mengendalikan penyakit ini berdampak negatif terhadap kerusakan lingkungan. Aplikasi organisme antagonis dan kultivar resisten merupakan alternatif pengendalian penyakit ramah lingkungan, berdampak positif terhadap kelestariannya, dan meningkatkan produktivitas lili. Penelitian bertujuan untuk mendapatkan informasi mikrobe antagonis, mikrobe nonpatogenik, dan klon lili yang dapat menekan penyakit layu Fusarium. Penelitian dilakukan di Laboratorium Biokontrol dan Rumah Sere, Balai Penelitian Tanaman Hias pada bulan Januari sampai dengan Desember 2007. Tata letak percobaan disusun berdasarkan rancangan acak kelompok pola faktorial denga tiga ulangan. Faktor pertama ialah klon lili yang terdiri dari klon No.1, No 2, No.3 (tahan), dan No.4 (rentan). Faktor kedua ialah perlakuan mikrobe antagonis (1) Gliocladium sp. 107 spora/ml, (2). Trichoderma sp. 107 sel/ml, (3) Fusarium a virulen 107 spora/ml dan, (4) kontrol (tanpa mikrobe antagonis). Hasil percobaan menunjukkan bahwa penggunaan mikrobe antagonis Gliocladium sp. dan klon resisten paling efektif mengendalikan penyakit busuk umbi Fusarium pada lili. Hal ini dibuktikan dari persentase tanaman layu pada perlakuan aplikasi mikrobe dan penggunaan tanaman resistant dibandingkan dengan tanpa perlakuan. Penanaman tanaman resisten diikuti dengan aplikasi Gliocladium paling efektif menekan layu Fusarium dibanding perlakuan lainnya. Lilium is one of the most important and the heigest economic value of cut flower in Indonesia. Cultivation of Lilium faces major constrain, that is wilt disease caused by Fusarium. Application of synthetic chemicals to control the diseases is not recommended, because its impact is dangerous for environment and human life. Therefore other control measures that are move environmentally friendly and more effective/efficient have to applied. The use of antagonistic microbes and resistance varieties are the most promising control measures to be recommended in the field. The study was aimed to find out of antagonist and nonpathogenic microbes and plant resistant that were effective to control Fusarium bulb rot on lili. The experiment was conducted at Laboratory and Glasshouse of Indonesian Ornamental Crops Research Institute (1,100 m asl.) on January to December 2007. Factorial experiment was arranged in a randomized block design with three replications. The first factor was Lilium clones i.e. No.1, No. 2, No. 3 (resistant), and No. 4 (susceptible clone as control). The second factor was antagonism microbes i.e. (1) Gliocladium sp. 107 spora/ml, (2). 107 Trichoderma sp. cel/ml, (3) Fusarium nonpathogenic 107 spora/ml, and (4) control (tap water without antagonist microbe). The results indicated that the use of Gliocladium sp. and resistant clone of Lilium i.e. clone No.3 was effective to control Fusarium bulb rot of Lilium. This proven from lower percentage of disease occurance on the treatment of antagonistics microbes and resistance varieties compared both to those of without treatment (control). The use of resistance plant followed by application of Gliocladium was known to be most effective to control fusarial wilt disease compared to the other treatment combinations.

This research was conducted in Pante Cermin, Padang Tiji Subdistrict, Pidie District. in March to August 2015, with the aim to know the use efficienci of Trichoderma sp on the growth of several types of Banana seedlings (Musa Paracica L.) This research using Randomized Block Design (RAK) factorial pattern with the factors studied is the type of banana and trichoderma dose . Both factors consist of 4 levels: Banana Barangan (J1), Ambon banana (J2), Banana King (J3) and Geupok banana (J4). While the dose of Tricoderma sp is: TO = 0 g / seeds T1 = 15 g / seeds T2 = 30 g / seedlings and T3 = 45 g / seedlings. So there are 16 treatment combinations and repeated 3 times, which resulted in 48 experimental units.To determine the influence of each treatment and its interaction on the growth of banana seedlings, the analysis of variance (Test F) and continued with the test of Beda Nyata Jujur (BNJ) at 5% level.The results showed that the growth of good banana seedlings among 4 species studied was shown by Barangan bananas, but not unlike bananas. However, trichoderma administration until the age of 4 months has not shown the growth and intensity of different attacks. So it should be extended the study period to 6 months. After 6 months of research there has been a difference in growth and intensity of attack, where the intensity of the greatest attack is shown by T0 (without trichoderma). Medium intensity of smallest attack is shown by T3 (Dose trichoderma sp 45 gr / banana seedlings). The type of banana does not affect the growth and intensity of fusarium wilt attack. and the interaction of these two factors had no significant effect on the growth of banana seedlings and the intensity of Fusarium wilt disease.

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.

This study was undertaken to examine the herbage accumulation dynamics and structural characteristics of digit grass subjected to different defoliation frequencies in the period of January 2015 to February 2016. Four defoliation frequencies [very high (25 cm), high (35 cm), medium (45 cm), and low (55 cm)] were evaluated in two periods of the year [greater insolation (September to March) and lesser insolation (April to August)]. The experiment was set up as a randomized-block design with four replicates. Overall, the decreasing defoliation frequencies increased the cutting interval; leaf area index; total-herbage, stem, and dead-herbage accumulation rates; and percentages of stems and dead herbage. This reduction in defoliation frequency also resulted in a lower leaf accumulation rate and percentage of leaves. In overall terms, digit grass showed higher total-herbage, leaf, and stem accumulation rates; percentages of stems and dead herbage; stem volume density; and tiller density in the period of greater insolation. In the period of lesser insolation, however, digit grass exhibited a lower dead-herbage accumulation rate and a lower percentage of dead herbage. Less frequent defoliations increase the herbage accumulation rates of digit grass, but result in a less desirable morphological composition.
