Efficacy of some inorganic salts on some fungi that isolated from different soils with salinity

الملخص AR

The study includes detect density of fungi in different soils with salinity ,also isolate some fungi and a study effect some salts such as: NaCl , NaCo3,NaSo4 and MgSo4 with concentrations 1000 ,5000 and 10000 ppm on these fungi in culture media .The result showed that colony forming unit (CFU) of fungi in different soils with salinity were correlated reversely with salinity level ,also there were different effect of salts depending on salt type and fungus ,then the salt NaCo3 was more effective on the fungi Alternaria citri and Alternaria alternata in concentrations 1000 ,5000 and 10000 ppm ,but this salt has a little effect on the fungi Aspergillus sp and Cladosporium sp .while the other salts has a slightly effect on the fungi .Therefore ,may using NaCo3 as antifungal against fungal pathogens and alternative substrate to fungicide after studying its side effects.
