The Mexican approach to face the recent coffee rust epidemic outbreak was to establish a
Regional Surveillance System operated by specifically trained personal at state level and
centrally coordinated by phytosanitary officials. The System integrates in a web platform field
monitoring and restricted-moving sampling with spatial and temporal data analysis based on
simple algorithms. In 342 sites, a total of 12 variables are weekly/biweekly measured related
to disease intensity, plant phenology and clime. Upon these variables, 12 indexes are
estimated to define early warnings at county level. Restricted spatial interpolations to coffee
growing sub-regions and four related indexes are also generated to identify risk-management
areas. In addition to the official scheme, spore trapping and disease assessment are also
conducted in selected areas using a research approach for purposes of data validation and
forecasting modeling. The web platform allows certified official to generated customized
graphics at all time to establish the epidemic status at state, county and site level. In addition,
indexes per county are weakly estimated to alert officials and state policy makers. In 2014,
nine additional coffee pests were included in the surveillance system.
