The inoculated Petri dishes were sealed with masking tape and incubated at 28˚C - 32˚C for five days in
alternating cycles of 12 hours light and darkness to induce growth of P. grisea. Radial growth of P. grisea was
then recorded after every three days for up to 21 days after inoculation by measuring mycelial growth diameters
along two diagonal lines previously drawn on the reverse side of each Petri dish to serve as a reference, using a
30 cm plastic ruler to determine the effectiveness of plant extracts
