  Twenty isolates of potato-associated fungi belonging to genera Aspergillus, Penicillium, Colletotrichum, and Trichoderma and recovered from healthy potato organs (stems, roots, and tubers) were screened for their antifungal potential toward Fusarium sambucinum and F. solani the major agents of dry rot disease in Tunisia. Tested using the dual culture method, all the potato-associated isolates had significantly lowered pathogen growth, noted after 7 days of incubation at 25°C as compared to the untreated control, but with a variable range depending on isolates used and targeted Fusarium species. F. sambucinum and F. solani were inhibited by 23.4 to 71.5% and by 29.2 to 62.1%, respectively, depending on antagonistic treatments tested. The percentage of Fusarium spp. inhibition ranged from 30.1 to 47.2% using Aspergillus spp. and from 30.1 to 67.3% with Penicillium s.. View More»
