Penelitian ini bertujuan untuk mengetahui : 1) pengaruh agens hayati Fusarium cf. solani dan Bacillus sp. dalam mengendalikan penyakit mosaik virus yang ditularkan oleh serangga vektor aphis, 2) pengaruh agens hayati Fusarium cf. solani dan Bacillus sp. terhadap komponen pertumbuhan tanaman cabai. Penelitian ini dilaksanakan di laboratorium perlindungan tanaman dan screen house Fakultas Pertanian Universitas Jenderal Soedirman. Waktu penelitian dimulai dari bulan Desember 2016 hingga Maret 2017. Penelitian ini menggunakan rancangan acak kelompok non faktorial. Penelitian ini terdiri dari enam perlakuan yaitu 1) penularan virus dan tanpa perlakuan (kontrol), 2) tanpa penularan virus, dan pemberian Bacillus sp, 3) penularan virus, dan pemberian Bacillus sp, 4) tanpa penularan virus, dan pemberian Fusarium cf. solani, 5) penularan virus, dan pemberian Fusarium cf. solani, dan 6) penularan virus, dan pemberian insektisida amitraz. Variabel pengamatan meliputi masa inkubasi, intensitas penyakit, tinggi tanaman, jumlah daun,  jumlah tunas, dan jumlah ranting. Hasil penelitian menunjukkan bahwa agens hayati Fusarium cf. solani dan Bacillus sp tidak dapat menekan intensitas penyakit, menunda masa inkubasi dan meningkatkan jumlah ranting, tetapi dapat meningkatkan tinggi tanaman sebesar 29,40% dan 26,56%, jumlah daun 23,47% dan 32%, serta menekan perkembangan tunas abnormal sebesar 42,4% dan 32,5% dibandingkan kontrol.

This research aims to know : 1) the effect of Fusarium cf. solani biological agents and Bacillus sp in controlling virus mosaic diseases transmitted by vector aphid, 2) the effect of  Fusarium cf. solani biological agents and Bacillus sp to the growth component of red chili. The research was carried out in Laboratory of Plant Protection and screen house of Agriculture Faculty of Jenderal Soedirman University Purwokerto. The research was conducted from December 2016 to March 2017. The research used Randomized Complete Block Design. The research consist of six treatments: 1) virus inoculation and without the biological agens (control), 2) without the virus inoculation and Bacillus sp application, 3) virus inoculation and Bacillus sp application, 4) without the virus inoculation and Fusarium cf. solani application, 5) virus inoculation and Fusarium cf. solani application, and 6) virus inoculation and pesticide application. Observed variables were incubation period, disease intensity, plant height, number of leaf, shoots, and branch. The result showed that the Fusarium cf. solani biological agents and Bacillus sp are unable to suppress the disease intencity, incubation period and the number of branch but could increase heigh of plant 29,40% and 26,56%, number of leaf 23,47% and 32%, and suppress of abnormal shoot 42,4% and 32,5% than control.
