Penelitian ini bertujuan untuk mengetahui 1) pengaruh pemberian agens hayati terhadap pengendalian penyakit oleh virus pada tanaman cabai merah, 2) pengaruh perlakuan agens hayati terhadap pertumbuhan dan hasil tanaman cabai merah. Penelitian dilaksanakan di Experimental Farm Fakultas Pertanian Universitas Jenderal Soedirman, Karangwangkal, Purwokerto Utara. Penelitian ini dilakukan selama lima bulan, mulai September 2020 hingga Januari 2021. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok, dengan 6 perlakuan dan jumlah ulangan 4 kali, jumlah unit percobaan ada 24 dan setiap unit terdiri atas 3 tanaman sehingga terdapat 72 unit tanaman percobaan. Perlakuan yang dicoba meliputi Kontrol, Trichoderma sp lahan marginal, Beauveria bassiana, Bacillus sp rizosfer albazia, formula cair  BioP60, dan insektisida Klorpirifos 400g/l. Variabel pengamatan meliputi, masa inkubasi, intensitas penyakit, serangga vektor virus, jumlah tunas, tinggi tanaman, jumlah buah pertanaman, dan bobot buah pertanaman. Data dianalisis dengan uji F pada taraf kesalahan 5%, apabila nyata, dilanjutkan dengan uji lanjut Duncan’s Multiple Range Test. Hasil penelitian menunjukkan pemberian Trichoderma sp, B.bassiana, dan formula cair BioP60, dapat menekan intensitas penyakit oleh virus, sedangkan perlakuan Bacillus sp. kurang mampu menekan intensitas penyakit oleh virus pada tanaman cabai merah. Pemberian formula cair BioP 60 selain mampu menekan intensitas penyakit oleh virus juga mampu meningkatkan tinggi tanaman, jumlah buah, dan bobot buah berturut turut, 18%, 33%, dan 59% dibandingkan kontrol. Serangga vektor yang menularkan virus penyebab penyakit yang ditemukan pada tanaman cabai dengan perlakuan agens hayati Trichoderma sp, Beauveria bassiana, formula cair BioP60 yaitu kutu daun, sedangkan pada perlakuan Bacillus sp yaitu kutu daun dan kutu kebul.

This research aims to determine 1) the effect of providing biological agents on disease control by viruses in red pepper plants, 2) the effect of biological agents on the growth and yield of red pepper plants. The research was conducted at Experimental Farm, Faculty of Agriculture, Jenderal Soedirman University, Karangwangkal, North Purwokerto. This research was conducted for five months, from September 2020 to January 2021. The experimental design used was a randomized block design, with 6 treatments and 4 repetitions, and each unit consisted of 3 plants so there were 72 experimental plant units. The treatments consisted of control, Trichoderma sp marginal land, Beauveria bassiana, Bacillus sp rhizosphere albazia, BioP60 liquid formula, insecticide Klorpirifos 400g/l. Observation variables include incubation period, disease intensity (%), virus vector insect, number of buds, the height of plants (cm), number of crops (g), and weight of crop fruit (g). Data were analyzed using the F test at an error level of 5%. If the results of the analysis show significantly different results, followed by further tests using Duncan's Multiple Range Test. The results showed that the treatment using Trichoderma sp., B. bassiana, Bacillus sp., BioP60 liquid formula, and Chlorpyrifos 400g/l insecticide was able to suppress intensity diseases by viruses in red chili plants, while the treatment of Bacillus sp. not able to suppress the intensity of disease by viruses in red chili plants. The treatment BioP 60 liquid formula beside able to reduce the intensity of disease by viruses also was able to increase plant height, fruit number, and fruit weight, respectively, by 18%, 33%, and 59% compared to control. Insect vectors that transmit disease-causing viruses found in chili plants treated with biological agents Trichoderma sp, Beauveria bassiana, BioP60 liquid formula were aphids, while in Bacillus sp treatments were aphids and whitefly.
