Resumen:
Wilting Pseudogynoxis benthamii plants were observed in Buenos Aires (Argentina) during March 2016, at 25% incidence. The aim of this study was to identify the causal agent of the disease. A fungal isolate obtained from sclerotia developed on roots, caused symptoms on inoculated healthy plants in 2 weeks. The pathogen was identified as Sclerotium rolfsii on the basis of morphological characteristics. The rDNA internal transcribed spacer was PCR-amplified and sequenced. DNA analysis revealed a 99-100% identity for S. rolfsii. This is the first report of S. rolfsii on P. benthamii and the first pathogen reported on this plant species worldwide.
