“…Survival and viability of fungal spores is solely dependent on the prevailing environmental conditions of which temperature, humidity, moisture, water activity (a w ), and gas tension forms major part. Findings made from this work revealed that: while almost all the fungal species identified infecting sorghum thus far were also found in the previous work of [16,17,18,19,20,21] in Nigeria, and in Burkina Faso [22,23], Sudan [24,25] Cameroon [26], Zimbabwe [27], South Africa [20,28], Tanzania [29], Americas [26,27] Brazil [30], Argentina [22] India [27,31], South east Asia [32], Europe and Oceania [33] and Australia [22], what is of major concern is the very high viability of the fungal spores in the studied areas. This is clearly indicative of the fact that, the storage facility currently in use in almost all the Agro ecological zones in Nigeria have very little impact in creating an unconducive environment for proliferation of fungal spores.…”
