Figure 3. Mycelial growth (cm) of Trichoderma spp. after inoculation growing by itself and in confrontation with M. phaseolina. The Percentage Inhibition of Radial Growth of M. Phaseolina (PIRGM) was determined as follows: PIRGM = [(R1-R2)/R1] × 100 where, R1 = radial growth of the pathogen and R2 = radial growth of the pathogen against Trichoderma spp; The Percentage of Radial Growth Acceleration of Trichoderma (PRGAT) was determined as follows: PRGAT= [(R2-R1)/R2] × 100 where, R1 = Radial growth of Trichoderma spp. and R2 = radial growth of Trichoderma spp. against the pathogen. Red lines indicate the growth of Trichoderma spp. and blue lines indicate the growth of Trichoderma spp. against M. phaseolina.
