Abstract

Colletotrichum sp. are significant plant pathogens that cause anthracnose,
leading to severe crop yield losses in various agricultural sectors. This study aims
to characterize the morphological diversity of Colletotrichum sp. isolated from five
districts in Yogyakarta Special Region (DIY). The research conducted in
Yogyakarta in January to June 2025. This research started with market explorations
in Yogyakarta therefore the isolate inoculated in a disposable PDA, hence that it
morphologically observed. Continued with in-vitro antagonism assay of
Trichoderma sp. against the Colletotrichum sp. isolates. This method started with
the classified sample taken then be put into antagonism PDA plate. Therefore
macroscopic parameters identification based on aerial and reverse view, texture,
growth rate, colony characteristics, and conidiomata. Microscopic parameters
include conidial shape, size and microscopic capture. The study results distinct
morphological groups among Colletotrichum sp. isolates showed three (BT, KP,
and SL) similar red coloured reverse view and white mycelium then two isolates
(YG and GK) with grey reverse view and white mycelium. (BT-KP, YG-GK, and
SL). The in vitro antagonism test result weak resistance to Trichoderma sp. The
mechanism of in vitro test between Colletotrichum sp. and Trichoderma sp. is that
Trichoderma successfully suppress the growth of Colletotrichum of all samples
with > 90% suppression.
