EPPO Reporting Service (2020/184) : in 2011, a serious disease of nutmeg (Myristica fragrans) was observed in several districts of Kerala. It was first attributed to Phytophthora ramorum (Mathew and Beena, 2012), but further investigations have shown that other Phytophthora species were causing this disease. Nutmeg isolates were found to be hybrid species: P. citrophthora x P. meadii and P. citrophthora x P. tropicalis for which the names P. citromeadii and P. citrocaptalis have been proposed, respectively (Anandaraj et al., 2020).
