Abstract
Culture filtrates, chloroform and ethyl acetate extracts of nine isolates of Aspergillus spp. (A. niger, A. terreus, A. flavus and Aspergillus sp.), isolated from soil and compost, were tested for antifungal activity against Pythium ultimum the causal agent of the potato Pythium leak. Culture filtrates showed a significant antifungal activity at the different tested concentrations. Total inhibition of the pathogen was induced by the filtrate of CH8 of Aspergillus sp., used at 10% (v/v) and those of CH12 (A. niger) and MC8 (A. terreus), applied at 20% (v/v). Chloroform and ethyl acetate extracts of isolates CH12 of A. niger, CH2 and MC8 of A. terreus and CH8 of A...
