This was done by cutting the damaged portion of the cocoyam tubers and blend with diluents (water) to have even distribution of the microorganism and ensure ease of plating out. This done with the sample and inoculation was done from the 4th test tube on SDA medium and incubated for three to seven days at the temperature 0f 270c. The isolate with the highest population was Fusarium species, which was found to be 38%, followed by Rhizopusspecies 25%, ... Continue Reading
