Abstract Citrus production is a significant agricultural activity in Brazil, the world's largest producer and exporter of orange juice.

The development of this disease is associated with climate conditions, such as temperature and leaf wetness duration (LWD). Citrus production in Brazil has recently migrated to regions with no records of greening disease (ca
