Abstract
The ability of Streptomyces sp. and Trichoderma harzianum has been widely tested in controlling pathogenic fungi. In the study by Hakim, L. (2023), it was proven that Streptomyces sp. isolate S6 could suppress Fusarium wilt disease. Meanwhile, in the study by Ummah, R. (2023), it was demonstrated that Trichoderma harzianum isolate TM was able to inhibit the growth of the pathogenic fungus Alternaria sp. Based on these two studies, Streptomyces sp. isolate S6 and Trichoderma harzianum isolate TM were used in this research to control anthracnose disease in bird’s eye chili plants caused by the pathogenic fungus Colletotrichum capsici. This study was conducted at the Plant Health Laboratory, Faculty of Agriculture, UPN Veteran Jawa Timur, and the isolates were collected from Bangeran Village, Mojokerto. The research period lasted from July 2024 to November 2024. The study consisted of two stages: the initial preparation stage, the in vitro research stage, and the in vivo research stage. The in vitro stage included compatibility tests, antagonistic tests, and growth media tests. Meanwhile, the in vivo stage involved testing the effectiveness of Streptomyces sp. isolate S6 and Trichoderma harzianum isolate TM on chili fruits and seeds. The results from the observed variables were analyzed using ANOVA. If significant differences were found, further testing was conducted using the Duncan Multiple Range Test (DMRT) at a 5% error level. The results showed that Streptomyces sp. isolate S6 and Trichoderma harzianum isolate TM exhibited compatibility, as they grew side by side without inhibiting each other. The combination of Streptomyces sp. isolate S6 and Trichoderma harzianum isolate TM was more effective in inhibiting the growth of Colletotrichum capsici compared to individual treatments. Additionally, the combination of Streptomyces sp. isolate S6 and Trichoderma harzianum isolate TM in rice washing water medium proved to be effective in suppressing anthracnose disease in chili plants.
