Disamping itu selain harga yang tinggi, di lapangan cabai merah sering  mengalami gangguan dari mulai benih disemai sampai tanaman cabai menghasilkan, hal ini disebabkan penyakit tular tanah atau pun terbawa benih. Salah satu penyakit yang memprihatinkan pada tanaman cabai merah adalah penyakit layu yang disebabkan oleh jamur Fusarium  oxysporum f.sp capsici,penyakit ini sering merugikan para petani, jika tanaman sudah terserang oleh penyakitini,  kerugian bisa mencapai 80 % pada tanaman cabai merah. Salah satu alternatif  yang digunakan dalam Pengendalian Hama dan Penyakit terpadu (PHPT) dengan menggunakan agensia Trichoderma formulasi pelet. Penelitian ini bertujuan agar mengetahui keefektifan Trichoderma  Formulasi pelet dalam menekan penyakit Layu Fusarium  yang disebabkan oleh Jamur Fusarium  oxysporum f.sp capsici. Penelitian ini telah dilaksanakan di laboratorium Penyakit Tumbuhan Program Studi Proteksi Tanaman dan Rumah Kasa Kebun Percobaan Fakultas Pertanian Unsyiah. Penelitian ini dimulai sejak bulan Agustus sampai Oktober 2017. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) pola non faktorial dengan 9 perlakuan dan 3 ulangan setiap perlakuan terdiri dari 5 unit polibag sehingga terdapat 135 unit polibag. Peubah yang diamati meliputi masa inkubasi, tinggi tanaman, jumlah daun dan persentase serangan.Hasil penelitian menunjukkan bahwa aplikasi pelet Trichoderma harzianum 2,5 g/polibagdan Trichoderma virens 2 g/polibag mampu memperlama masa inkubasi (Tidak terdapat gejala). Aplikasi pelet  T. virens 1,5 g polibag dapat meningkatkan tinggi tanaman cabai merah sampai 16, 80 cm. Aplikasi pelet T. harzianum  1,5 g/polibag dapat mamacu pertumbuhan  jumlah daun sebesar 9,07 helai. Aplikasi pelet T. harzianum 2,5 g/polibag dan T. virens formulasi pelet 2 g/polibag mampu menekan persentase serangan jamur Fusarium  oxysporum f.sp capsici sebesar 13,68 % pada 35 hari setelah tanam.Combination of Several Doses and Species of Trichoderma Pellet Formulations In Suppressing Development Fungus of fusarium oxysporum f.sp capsici in Red Chili Breeding (Capsicum annum L.)Abstract : a red chili (Capsicum annum L.) is one of the largest superior horticultural commodity of vegetables, because it has a high selling price.

Three biocontrol agent viz., Trichoderma viride, Trichoderma virens and Trichoderma harzianum were evaluated to test the antagonism against Fusarium udum under in vitro conditions. All the three biocontrol agents have the potential of parasitizing the growth of Fusarium udum in vitro. The rate of parasitism was found fastest in T. viride (61.12% over growth in 96 hrs) than T. virens and T. harzianum. The volatile compounds from Trichoderma viride suppressed the mycelial growth of Fusarium udum by 43.13% and found effective when compared to Tricho-derma virens and Trichoderma harzianum. Non-volatile compounds or culture filtrate from Trichoderma virens at 15% concentration shows complete mycelial inhibition of the test fungi. The antagonist T. virens was chosen to be the most promising bio-control agent for F. udum.

Abstract A comparison was made of Canadian sphagnum peat (SP) and Philippine coconut (Cocos nucifera L.) coir dust (CD) as growing media components for greenhouse production of Dracaena marginata Bak. and Spathiphyllum Schott ‘Petite’. Three soilless foliage plant growing mixes (Cornell, Hybrid, University of Florida #2 [UF-2]) were prepared using either SP or CD and pine bark (PB), vermiculite (V), and/or perlite (P) in the following ratios (% by vol): Cornell = 50 CD or SP:25 V:25 P, Hybrid = 40 CD or SP:30 V:30 PB, UF-2 = 50 CD or SP: 50 PB. Dracaena root growth was not affected by treatments but there were significant mix × media component interactions that affected plant top growth parameters. In general, the growth and quality of D. marginata were reduced by using CD in Cornell, had no effect in Hybrid, and increased in UF-2. S. ‘Petite’ grew equally well in all growing mixes regardless of whether CD or SP was used; however, plants grew more in Cornell and Hybrid than in UF-2. S. ‘Petite’ roots, which were infested with Cylindrocladium spathiphylli, had higher grades when grown in CD than when the media contained SP.
