Screening of the Trichoderma isolates for their cadmium tol- erance revealed that the isolates varied significantly in their levels of tolerance, irrespective of the cadmium concentra- tions tested (Table 3). There was a significant reduction in the mycelial growth of the Trichoderma isolates upon exposure to cadmium (Fig. 3). At a cadmium concentration of 40 ppm, the maximum mycelial growth was shown by IBT-II (73.4 mm), which was significantly higher than that of UBT-18 (66.6 mm), followed by MT-4 and MT-24 (62.6 and 62.2 mm, respectively). The degree of tolerance of the Trichoderma isolates, irrespective
