Resumo

Fungal endophytes were isolated from 12 Artemisia species. 57 strains were evaluatedfor their antagonist traits against Sclerotinia sclerotiorum and 33 of them were consideredbioactive. Almost all strains in Aspergillus taxa (3 of 4 species) performed as rapid colonizers ofthe substrate in the dual culture interaction. Both strains identified as Epicoccum nigrumdetained pathogen growth at > 2 mm. Of 19 endophytic fungal solvent extracts two strainsidentified as Alternaria alternata and Stemphylium sp. inhibited mycelial growth in biometricassay with 42.40% and 81.41%, respectively (at [C] = 1%). Almost 4 times more strains werefound as potential antagonists than as bio - sources of solvent extracted active metabolites (33strains versus 8).
