3.1.1. Isolation and phenotypic identification
Isolates of biocontrol agent were examined macroscopically and
microscopically. They were found to form colonies with white
mycelia, becoming green when forming conidia and conidiophores.
There were conidia formed densely over the center and undulating
concentric rings toward the edge. According to Kubicek and
Harman (2002), they were identified as Trichoderma spp. Also,
growth of the pathogenic isolates on PDA produced aerial (dense
and floccose) whitish mycelia. Observation through the bottom
of Petri dishes showed production of yellowish/cream-white pigmentations by some isolates at young age. These colours either
remained with time or changed into purple or whitish. The growth
