Abstract

Trichoderma sp. is a saprophytic fungus found in various environments, one of which is in the rhizosphere of oil palm plants which can be used to control Ganoderma and increase the resistance of oil palm plants from stem rot disease. This study aimed to characterize the morphology of Trichoderma spp. origin of peat land in oil palm plantations in Kampar Regency and screening the potential in controlling Ganoderma sp. Trichoderma spp. from oil palm rhizosphere was collected from the smallholder oil palm plantations in Deli Makmur Village, Kampar, Indonesia. This research was conducted by several observations, such as the hypovirulence test; identification of the morphology of Trichoderma spp. fungus; growth and diameter test of Trichoderma spp. fungus; test of the inhibitory ability of Trichoderma spp. fungus against Ganoderma sp. LPTUNRI-Gan002 isolate; test for hyperparasitism of the fungus Trichoderma spp., which has high antagonistic power against Ganoderma sp. isolate. Six Trichoderma spp. isolates had morphological characteristics similar to two species, i.e., Trichoderma harzianum (LPTUNRI-Trc001, Trc004, Trc005, and Trc006 isolates) and Trichoderma asperellum (LPTUNRI-Trc002 and Trc003). LPTUNRI-Trc003 had the highest diameter (90 mm), growth rate (32.66 mm/day), and the highest ability to suppress Ganoderma sp. LPTUNRI-Gan002 (91.03%) compared to the other five isolates.

Abstract

This research aimed to determine the potential of endophytic Trichoderma sp originated from oil palm plant tissue as a biological control agent and its molecular identification. The potency assay was carried out using a completely randomized design consisting of three isolates of Trichoderma sp. from different plant tissues (TR01 from root tissue, TS01 from stem tissue, and TM01 from midrib tissue) with inhibitory ability parameters. The inhibition of the growth of G. boninense was performed at the concentration of 15% and 20%, and the molecular identification of Trichoderma sp. endophyte isolates was analyzed using BLAST software. The results showed that Trichoderma sp. TM01 isolate had larger inhibitory than the other isolates on days 3 and 4 by 60% and 68%. TM01 isolate also showed inhibition to the growth of the G. boninense at 15% and 20%, with the percentage of inhibition reaching 71.79% and 82.05%. Based on phylogenetic analysis, the three endophytic isolates of Trichoderma sp. were closely related to Trichoderma virens.
