Abstract: The first location where the frequency ratios of the isolated fungi were 73.78% - Aspergillus niger, 66.87% - Aspergillus flavus, 34.69% - Alternaria sp., 22.99% - Fusarium sp., 15.65% - Rhizopus sp., 11.54% - Penicillium sp. and Cladosprium sp. - 5.87% was in the north of Al-Diwaniya city. Whereas the percentage of fungi frequency in the air before the rains occurred in the same location was 41.77% Aspergillusniger, 43.56% Aspergillusflavus, 11.56% Alternaria sp., 8.95% Fusarium sp., 4.64% Rhizopus sp., 4.55% Penicillium sp. and Cladosprium sp. was 0% (while the frequency ratio for fungi isolated from the air after the rain was 3.45% Aspergillus niger, 2.63% Aspergillus flavus, 0% Alternaria sp., 0% Fusarium sp., 0% Rhizopus sp., 0% Penicillium sp. and Cladosprium sp. was 0%). In the second location in the south of Al-Diwaniya city the frequency ratios of isolated fungi was 77.45% Aspergillus niger, 71.64% Aspergillus flavus, 40.18% Fusarium sp., 30.24% Rhizopus sp., 23.85% Alternaria sp. and Penicillium sp. was 14.74%, respectively, while the fungus Cladosprium sp. did not appear. The results showed that the percentage of fungi contamination was more in the southern region of the city. Whereas the percentage of fungi frequency in the air before the rains occurred in the same location was 50.43% Aspergillus niger, 48.54% Aspergillus flavus, 22.36% Fusarium sp., 18.19% Rhizopus sp., 13.54% Alternaria sp., 11.67% Penicillium sp. and Cladosprium sp. was 0%. While was the frequency ratio for fungi isolated from the air after the rain was 3.46% Aspergillus niger, 3.53% Aspergillus flavus, 0% Alternaria sp., 0% Fusarium sp., 0% Rhizopus sp., 0% Penicillium sp. and Cladosprium sp. was 0%).
