PEREZ-VICENTE, Luis. Moniliophthora roreri H.C. Evans et al. and Moniliophthora perniciosa (Stahel) Aime: impact, symptoms, diagnosis, epidemiology and management. Rev. Protección Veg. [online]. 2018, vol.33, n.1, pp.00-00. ISSN 1010-2752.

Witches’ broom and frosty pod rot of cacao caused by Moniliophthora perniciosa (Stahel) Aime and Moniliophthora roreri H.C. Evans et al. respectively, are two diseases original from South America with a limited geographic distribution and a strong impact on production and quality of cacao. The reports of their presence in Cuba are not exact and the pathogens were not found in the surveys conducted by the author between 2013 and 2016. The previous reports on the witches’ broom presence in Cuba were related to the disease known as green point gall caused by Fusarium decemcellulare Brick. In the present paper, the studies carried out by the author on the symptoms, morphological structures, and colonies of both pathogens in Ecuador, Venezuela, and Costa Rica are documented, and the information on their phylogenetic relationships, epidemiology and management are updated. The spores of both species are disseminated by water, wind, and infected plant parts. Cacao harvesters are important vectors of M. roreri spores being transported on clothes. Prevention and management of both diseases are based on strict quarantine measures; sanitation and destruction of branches, stems, and infected fruits; use of resistant clones and applications of fungicides and antagonists to stems, branches, and fruits. Both species are included in the list of quarantined pests of Cuba. The presence of M. roreri in Jamaica is a threat for the cacao production in the west of Cuba
