Abstract

Ceratocystis sp. is an important pathogen in acacia plants. This pathogenic fungus causes stem rot disease which can cause the death of mature plants within 4 - 7 years with a disease attack percentage of nearly 80%. The common controlling technique is carried out by using chemical pesticides, for that we need another alternative to reduce its negative impact, namely the use of Trichoderma spp. endophyte. This research aimed to determine the potential of the Trichoderma spp. endophytes in suppressing the development of the Ceratocystis sp. The study was conducted experimentally using a completely randomized design (CRD) consisting of 7 treatments with three replications, namely without Trichoderma sp. endophytic (E0), two isolates of T. virens endophytic of oil palm plants (E1-E2), one isolate of T. harzianum endophytic of rubber plants (E4), three isolates of Trichoderma sp. endophytic of acacia plants (E5-E7), and one isolate Trichoderma sp. endophytic of eucalyptus plant (E14). The parameters observed were the antagonistic ability, colony diameter, growth rate of Trichoderma spp. colonies, and its inhibition mechanism against Ceratocystis sp. Based on the results of this study, Trichoderma sp. endophytic E074 isolated from 4 years old Acacia crasicarpa had the highest antagonistic ability (30.76%), diameter (90 mm), and growth rate (33.33 mm.day-1) compared to other isolates with hyperparasitic entrapment type.
