Bioprospecting and mechanistic insights of <i>Trichoderma</i> spp. for suppression of <i>Ganoderma</i>-induced basal stem rot in oil palm.

ABSTRACT:

Purpose

Basal stem rot (BSR), with Ganoderma spp. as the principal causative agent, is an important oil palm disease, leading to significant stand loss and reduced yield potential. The use of antagonistic fungi, particularly Trichoderma spp., offers a sustainable approach to disease suppression through hyperparasitism, antibiosis, and rhizosphere competence. However, strain-dependent variability in antagonistic potential necessitates the selection of the most efficacious isolates for integrated BSR management. Here we show that T. afroharzianum exhibits superior antagonism against Ganoderma spp., in dual culture, inverted plate assay as well as cellfiltrate assays.

Methods

From 50 Trichoderma isolates screened, 12 highly mycoparasitic strains (>80
