AMECAFE said exports through the first 10 months of the current 2012/2013 harvesting season totaled 2.9 million bags, up 7.3 percent compared to the same ten-month period during the previous 2011/2012 season.
Meanwhile, coffee exports from Nicaragua rose 13.2 percent in July compared to the same month a year ago, reaching 166,155 60-kg bags, the country's national exports council Cetrex said on Friday.
Cetrex said shipments through the first 10 months of the 2012/2013 season totaled 1.7 million bags, up 28 percent compared with the same period the previous season.
Aggressive roya outbreaks have been reported this season in Mexico and each of Central America's major coffee-producing nations, threatening sharply reduced yields and export revenues this season and beyond.
Roya, or coffee leaf rust, is a wind-born fungus spread by spores that kill or significantly weaken trees once infected.
Last month, Mexico's agriculture minister said 25,000 farmers were receiving fungicides to combat roya, part of a plan that would expand to cover about 250,000 hectares of coffee plantations in Chiapas, Mexico's top-producing state.
The coffee season in Central America and Mexico, which together produce more than one-fifth of the world's arabica beans, runs from October through September.
