| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui keefektifan beberapa agensia pengendali hayati dalam mengendalikan penyakit utama pada tanaman cabai, serta meningkatkan pertumbuhan dan produksi tanaman cabai. Penelitian ini dilaksanakan dari bulan Desember 2013 sampai dengan bulan April 2014 di Lahan penelitian Laboratorium Pengamatan Hama dan Penyakit Temanggung di Desa Salamsari, Kecamatan Kedu, Kabupaten Temanggung. Penelitian menggunakan Rancangan Acak Kelompok dengan 5 perlakuan dan 5 ulangan. Perlakuan yang dicoba meliputi: kontrol, disiram P. fluorescens P60 sebanyak 6 kali (20 mL/tanaman), ditaburi jamur Mikoriza saat tanam (100 g/tanaman), disiram Trichoderma harzianum isolat jahe sebanyak 6 kali (20 mL/tanaman), serta disiram dan disemprot larutan pestisida kimia sintetis setiap 2 minggu sekali. Variabel yang diamati meliputi masa inkubasi, intensitas penyakit, tinggi tanaman, bobot segar dan kering tanaman, bobot segar dan kering akar, serta bobot buah. Hasil penelitian menunjukkan bahwa penggunaan agensia hayati P. fluorescens P60 dan T. harzianum isolat jahe efektif untuk mengendalikan penyakit layu fusarium dan virus kuning karena mampu menekan intensitas masing-masing penyakit sebesar 60-70,28% dan 86,46-87,5%, namun belum efektif untuk mengendalikan penyakit antraknosa. Penggunaan agensia hayati berpengaruh terhadap komponen pertumbuhan, penggunaan P. fluorescens mampu meningkatkan tinggi tanaman, bobot segar dan kering akar masing-masing sebesar 10,71, 14,08 dan 16,83%, mikoriza mampu meningkatkan bobot segar dan kering akar 14,89 dan 17,45%, namun penggunaan agensia hayati belum mampu meningkatkan komponen hasil produksi buah cabai. |

| Abtrak (Bhs. Inggris) | This research aimed at determining the effectiveness of several biological control agents in controlling the primary chili diseases and increasing the chili growth and yield. The research was conducted from December 2013 to April 2014 in the experimental field at the Laboratory of Plant Pests and Diseases Observation, Salamsari Village, Kedu Sub-District, Temanggung Regency. Randomized block design was used with five treatments and five replicates. The treatments tested included control, pouring P. fluorescens P60 for 6 times (20 mL crop-1), dusting mycorrhiza at planting time (100 g crop-1), pouring Trichoderma harzianum ginger isolate for 6 times (20 mL crop-1), and pouring and spraying synthetic chemical pesticide every two weeks. Variables observed were incubation period, disease intensity, plant height, fresh and dry weight of plant, fresh and dry weight of roots, and fruit weight. The results showed that the use of biological agents P. fluorescens and T. harzianum isolates P60 ginger is effective for control of Fusarium wilt disease and the virus is able to suppress the yellow because each disease was 60 to 70.28% and from 86.46 to 87.5 %, but they were not yet effective for controlling anthracnose disease. The use of biological agents affect the growth component, The use of biological agents affect the growth component, P. fluorescens were able to increase plant height, fresh and dry root weight respectively 10.71, 14.08 and 16.83%, mycorrhizae can improve the fresh and dry weight of roots 14 89 and 17.45%, but the treatment of biological agents have not been able to increase component production chilies. |
