A new fungus, named Pseudopestalotiopsis gilvanii, has been discovered to affect guarana plants, causing leaf disease. The fungus was identified through field observations, isolations, and laboratory analyses by Embrapa Amazônia Ocidental's Laboratory of Molecular Biology. It belongs to the pestalotiopsis group, which causes diseases in various hosts. The fungus was also found to affect açaí palms and oil palm but did not affect banana. This discovery highlights the need for monitoring and further research into this new pathogen.

The discovery was made in research based on field observation, isolation of the fungus and laboratory analyzes with morphological and molecular characterization, carried out by the Laboratory of Molecular Biology of Embrapa Amazônia Ocidental (AM). The new species belongs to the group of fungi called pestalotiopsis, which encompasses three genera (Pestalotiopsis, Pseudopestalotiopsis and Neopestalotiopsis) and causes diseases in a wide range of hosts. In guarana, species belonging to two of the three genera that include pestalothioids were identified. Of the six strains analyzed, three were identified as ...
