Two Penicillium species, viz P. brevicompaetum and P. corymbiferum, were isolated from senescent petioles of cyclamen and from bulbs of lilies, respectively, both samples treated previously with benomyl. The isolates turned out to be very resistant to this fungicide when grown on malt agar, supplied with the fungicide; at a concentration of 2000 ~zg/ml they were less inhibited than randomly chosen isolates of the same species on agar with 1 tzg/ml.The strains retained their resistance at the same level for at least 3 months after repeated subculturing on fungicide-free agar.Resistance to benomyl coincided with resistance to methyl-thiophanate and, to a lesser extent, also to thiabendazole and furidazol.

“…was evaluated on Potato Dextrose Agar (PDA) medium amended with the compounds at increasing concentration (from 5 to 100 µM). The Petri dish method was applied, according to Thanassoulopoulos et al [ 43 ]. Control cultures were prepared amending PDA with equivalent volumes of DMSO (≥99.9%, Sigma Aldrich, St Louis, MO, USA), ranging from 0.25% to 1%.…”

As key players in biotic stress response of plants, jasmonic acid (JA) and its derivatives cover a specific and prominent role in pathogens-mediated signaling and hence are promising candidates for a sustainable management of phytopathogenic fungi. Recently, JA directed antimicrobial effects on plant pathogens has been suggested, supporting the theory of oxylipins as double gamers in plant-pathogen interaction. Based on these premises, six derivatives (dihydrojasmone and cis-jasmone, two thiosemicarbazonic derivatives and their corresponding complexes with copper) have been evaluated against 13 fungal species affecting various economically important herbaceous and woody crops, such as cereals, grapes and horticultural crops: Phaeoacremonium minimum, Neofusicoccum parvum, Phaeomoniella chlamydospora, Fomitiporia mediterranea, Fusarium poae, F. culmorum, F. graminearum, F. oxysporum f. sp. lactucae,F. sporotrichioides, Aspergillus flavus, Rhizoctonia solani,Sclerotinia spp. and Verticillium dahliae. The biological activity of these compounds was assessed in terms of growth inhibition and, for the two mycotoxigenic species A. flavus and F. sporotrichioides, also in terms of toxin containment. As expected, the inhibitory effect of molecules greatly varied amongst both genera and species; cis-jasmone thiosemicarbazone in particular has shown the wider range of effectiveness. However, our results show that thiosemicarbazones derivatives are more effective than the parent ketones in limiting fungal growth and mycotoxins production, supporting possible applications for the control of pathogenic fungi.

“…With F. oxysporum rapid development of tolerance to benomyl was observed by subculturing this fungus on media with successively higher benomyl concentrations (Thanassoulopoulos et al, 1971;Maraite, unpublished data Emergence of tolerance in liquid medium. In liquid MM medium containing more than 1.5 ~g/ml benomyl, germination of conidia was only slightly delayed but germ tubes were enlarged and curled and showed short coiled ramifications.…”

Tolerance to benomyl in Botrytis cinerea and Fusarium oxysporum

In 1974, a field survey revealed a widespread occurrence of benomyl tolerance in Botrytis cinerea. When young mycelium discs were transferred to media with different benomyl concentrations, various tolerance groups could be distinguished, Cultures obtained by hyphal tip isolations from these isolates and replicated by means of a multipin replicator showed only two types of response: inhibition by 0
