INDUKSI RESISTENSI MENGGUNAKAN SENYAWA ACIBENZOLAR-S-METHYL SEBAGAI PENGENDALIAN PENYAKIT Ceratocystis PADA TANAMAN DUKU (Lansium domesticum Corr.) DI SUMATERA SELATAN

---

The duku plant (Lansium domesticum Corr.) is a leading horticultural commodity in South Sumatra, but in recent years it has experienced a decline in productivity due to wilt disease caused by the Ceratocystis pathogen. This study aims to evaluate the effectiveness of the compound Acibenzolar-S-Methyl (ASM) as a resistance inducer in suppressing the development of Ceratocystis disease in duku plants through in vitro and in vivo approaches. The study was conducted with five ASM concentration treatments (0–4 mg/L) using a completely randomized design. The in vitro test results showed that all ASM treatments significantly inhibited mycelium growth with a lower colony area than the control, where the treatment without ASM produced the highest mycelium area of 43.51 cm², while the ASM treatments ranged from 28.33 to 32.23 cm². In vivo testing showed that low to medium concentrations of ASM reduced disease intensity by up to 27.5% and suppressed plant mortality to 0% in several treatments, compared to the control, which reached 80% attack intensity with 50% mortality. Additionally, ASM application also influenced plant physiological responses, as indicated by increased chlorophyll (CHL) and leaf nitrogen levels at several concentrations, which play a role in maintaining plant vitality. However, the highest concentration (4 mg/L) shows phytotoxic tendencies in the form of increased disease attacks and decreased physiological parameters. Overall, this study proves that Acibenzolar-S-Methyl has the potential to be an effective systemic resistance activator in suppressing the development of Ceratocystis disease in duku plants, especially at low to medium doses, thus providing an environmentally friendly control alternative in the field.
