Online published on 27 December, 2023. Abstract Laboratory evaluation of different substrates for their suitability in mass production of five isolates of Trichoderma spp. revealed that the potato dextrose broth media providing largest population in isolate 1 (277.7 ×104 cfu g−1), isolate 2 (196.3 ×104 cfu g−1), isolate 3 (247.7 ×104 cfu g−1), isolate 4 (266.3 ×104 cfu g−1), and isolate 5 (237.3×104 cfu g−1) after two months of storage proved the best. Different species’ populations dropped gradually with the pace of loss varying with substrate. The lowest population of all the five species of Trichoderma was produced with rice straw.
