Abstract
Chili peppers (Capsicum annuum L.) are an important horticultural commodity in Indonesia with high market demand, so production must be maintained to ensure stability. However, chili pepper production is often hampered by bacterial wilt caused by Ralstonia solanacearum. Chemical control methods are still widely used. Therefore, more environmentally friendly control alternatives are needed, one of which is through the use of biological agents such as Trichoderma sp. The formulation of Trichoderma sp. in the form of granules made from rice bran and rice husks is expected to improve stability, viability, and ease of application in the field. This study aims to determine the effectiveness and potential of Trichoderma sp. granules made from rice bran and rice husks in inhibiting the growth of Ralstonia solanacearum. The study was conducted from June to December 2025 at the Plant Health Laboratory of the Faculty of Agriculture, UPN “Veteran” Jawa Timur, and Kebun Bibit Wonorejo. In vitro test results showed that at 24 hours, the TG and KT treatments exhibited the highest inhibitory activity, while at 48 hours, there was no significant difference. Between 72 and 120 hours, inhibitory activity increased across all treatments, with KT showing the highest activity, and the density of Trichoderma sp. spores also increased during the observation period. In vivo test results showed that TG was able to delay symptoms until 37 day after sowing, with the highest disease intensity in K0 starting at 44 day after sowing. At 51 day after sowing, TG (14%) differed significantly from K0 (43%), whereas at 58 day after sowing, all treatments did not differ significantly but remained lower than the control.
