The country has prohibited avocados from a number of countries including the State of Florida in the United States to protect against a disease called Sunblotch.
This is a disease that is caused by viroids, small strands of genetic material much smaller than a virus.
The disease reduces plant yield and can be passed on by grafting or through pollen. Other forbidden imports come from Australia, Spain, Ghana, Guatemala, Israel, México, South Africa and Venezuela.
Costa Rica has 2,000 hectares in avocado trees and produced 2,000 metric tons a year, said the Servicio Fitosanitario del Estado.
The agency also said that a survey of the country’s trees showed that the disease was not present.
