Figure 4. Mycelial growth (cm) of M. phaseolina growing by itself and in confrontation with different Trichoderma spp strains. 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 exponential growth of M. phaseolina and blue lines indicate the growth of M. phaseolina against Trichoderma spp.
