STABILITY STUDIES OF SOME ANTIFUNGAL AGENTS ACTIVITIES AGAINST SELECTED PHYTOPATHOGENIC FUNGI SPORES

Fungi infections have been implicated as one source of yam tuber spoilage. The effects temperature, pH and storage duration on antifungal activities selected combined agents were investigated using the agar-well diffusion agar dilution method against Aspergillus niger spores. test combine are: Fluconazole/Sodium propionate (5000/5000?g/ml), Terbinafine Hcl/ Sodium (500/5000?g/ml), ketoconazole / (2000/5000?g/ml), Fluconazole Griseofulvin (2000/5000?g/ml) (500/5000?g/ml). at 25 - 70 ºC varies while neutral & alkaline chemical remained relatively unaffected. There was no significant changes in spores p>0.05 throughout period six months investigation. these finding with relation to stability for preserving tubers is discussed this work.
