A coffee worker Petrona Lopez Chiquival takes rests against a tree on a coffee plantation in Santiago Atitlan, Guatemala, Friday, Feb. 8, 2013. Guatemala's President Otto Perez Molina has declared a national emergency over the spread coffee rust, a fungus that is affecting 70 percent of the country's crop. Molina said Friday that the pesticides will start being applied to coffee plants in April and that two more applications will be needed during the year. (AP Photo/Moises Castillo)
