Penelitian ini bertujuan untuk mengetahui pengaruh lama perendaman benih mentimun dalam metabolit sekunder Trichoderma harzianum terhadap penyakit virus dan pertumbuhan tanaman mentimun. Penelitian dilakukan di Laboratorium Perlindungan Tanaman dan Rumah Kaca Fakultas Pertanian Universitas Jenderal Soedirman, Purwokerto selama empat bulan mulai Desember 2017 sampai dengan Maret 2018. Penelitian menggunakan Rancangan Acak Kelompok dengan 4 perlakuan dan 6 ulangan. Perlakuan yang dicoba meliputi: Kontrol (perendaman benih mentimun dengan air steril selama 30 menit), perendaman benih mentimun dalam larutan metabolit sekunder T. harzianum selama 30 menit, 60 menit, dan 90 menit. Variabel yang diamati meliputi masa inkubasi, intensitas penyakit, kejadian penyakit, AUDPC atau luas area di bawah kurva perkembangan penyakit, tinggi tanaman, bobot basah tanaman, fase awal berbunga, jumlah daun, dan kandungan fenol. Hasil penelitian menunjukkan bahwa perendaman benih mentimun menggunakan metabolit sekunder T. harzianum selama 30 menit mampu menekan patogen virus dengan menekan masa inkubasi sebesar 9,82%; intensitas penyakit sebesar 24,24%; kejadian penyakit sebesar 33,22%, meningkatkan pertumbuhan tanaman dengan meningkatkan tinggi tanaman sebesar 11,3% dan bobot basah tanaman sebesar 7,65%, dan meningkatkan kandungan fenol.

The aim of this research was to observe the influence of cucumber seed soaking time in secondary metabolite of Trichoderma hazianum against disease virus and to the growth of cucumber. This research was conducted in plant protection  labolatory and  green house of Jenderalsoedirman University, Purwokerto for 4 months, from desember 2017 until maret 2018. Randomized Block Design (RBD) was used for this research using 4 treatment and 6 replication. The treatments were: control (soaking  the cucumber seed in sterile water for 30 minute), soaking the cucumber seed secondary metabolite of T harziarum for 30 minute, 60 minutes, and 90 minutes. The variable observed were incubation period, disease intensity, the incidence of the desease, AUDPC or area under disease progress curve, plant height, fresh weight of the plant, early flowering period, number of leaves, and phenol content analysis of cucumber. The result of this research showed that seed soak treatment by secondary metabolite T. harzianum for 30 minutes could suppress the growth of virus by suppress incubation period 9,82 %; disease intensity 24,24 %; the incidence of the disease 33,32; increased the growth of plant by increasing the plant height 11,3 % and fresh weight of plant 7,65 %, increased the phenol content.  
Key word : T. harzianum, secondary metabolite, virus, cucumber, seed soaking
