Damping off is one of the diseases caused by soil-borne pathogens resulting in the death of seedling in a short time. Control of this disease is quite difficult. The study aimed to examine the potential of biofertilizers and the time of application to damping off disease intensity and plant growth on Japansche citroen seedling. This study used a Factorial Completely Randomized Design with two factors: 1). Biofertilizer namely AzzoFor (P1), liquid biofertilizer (P2), a secondary metabolite of Trichoderma asperellum (P3), the mixture of three biofertilizers (P4), and control (P5), 2). The time of application, namely the treatment of biofertilizers first then followed by the inoculation of F. oxysporum . (A1) and the treatment of F. oxysporu first followed by treatment of biofertilizer (A2). The results showed that the lowest disease intensity was found in A1P3 treatment (0%), while in control reached 41.3%. The treatment of A1P2, A2P1, A2P2 and A2P4 showed the same disease intensity. The highest disease control effectiveness found in A1P2, A1P3, A2P1, A2P2 and A2P4 treatments and this was significantly different compared to A1P4, A2P3 and control treatments. The most significant percentage of seeds germinate at 21 DAS was shown in A1P1 treatment (26.7%) and A2P3 treatment (25.3%), while after 28 DAS, it was in A2P4 treatment (73.3%). The lowest plant height at 28 DAS was A1P4 treatment and control. Biofertilizer is useful for controlling the damping-off disease if applied separately.
