Penelitian ini bertujuan untuk mengetahui keefektifan dua isolat Trichoderma sp. dalam formula padat dan cair organik terhadap penyakit karena virus pada tanaman cabai besar, dan pengaruhnya terhadap pertumbuhan dan hasil tanaman cabai besar. Penelitian dilaksanakan di Lahan Petani Cabai Desa Banteran, Kecamatan Sumbang, Kabupaten Banyumas pada ketinggian tempat 600 mdpl, mulai Desember 2014 sampai dengan Maret 2015. Digunakan Rancangan Acak Kelompok, dengan 5 perlakuan dan 5 ulangan terdiri atas Kontrol, Trichoderma sp. isolat Jahe, Trichoderma sp. isolat Bawang Merah, Trichoderma sp. Gabungan isolat jahe dan bawang merah, dan insektisida (sipermetrin 1 mL/L). Variabel yang diamati yaitu masa inkubasi, intensitas penyakit dan laju infeksi, kepadatan akhir, tinggi tanaman, panjang akar, bobot akar segar, bobot akar kering, bobot tanaman basah, bobot tanaman kering, saat berbunga pertama, bobot buah per tanaman, jumlah buah per tanaman, dan analisis jaringan. Hasil penelitian menunjukkan bahwa aplikasi dua isolat Trichoderma sp. dalam formula padat dan cair organik belum mampu menekan penyakit virus serta meningkatkan pertumbuhan dan hasil tanaman dan kandungan senyawa fenol pada tanaman cabai besar.

This research aimed at knowing to determine the effetiveness of two Trichoderma sp. isolates in solid and liquid organic formulation to viral disease on chili, and the effect on growth and yield on chili. This research was carriedout at the screen house, and the chili field at Banteran Village, Sumbang Sub-District, Banyumas Regency at altitude of 600 m above sea level started from December 2014 to March 2015. Completely Randomized Block Design was used with 5 treatments repeated 5 times. The treatments were control, Trichoderma sp. ginger, onion, and combination of onion+ ginger isolates, and insecticide with active ingredients of sipermetrin1 mL/L. Variables observed were incubation period, , disease intensity and infection rate, Trichoderma sp. late density, crop height, root length , fresh root weight, dry weight of root, fresh weight of crops, dry weight of crops, fruit weigh, number of fruits, and phenolic compoundsanalysis. Results of the research showed that application of two Trichoderma sp. isolates in solid and liquid organic formulation wasn’t effective to suppress the viral disease and to increase on chili growth and yield and phenolic compounds.
