Essential oils for rust control on coffee plants Óleos essenciais no controle da ferrugem em cafeeiro

Ciência e Agrotecnologia, 2012
Rust is considered the most important disease in coffee because it causes severe defoliation in plants and, consequently, reduction in productivity. This study evaluated the in vitro effect of essential oils of cinnamon, citronella, lemongrass, clove ...

Involvement of peroxidases in the coffee resistance to orange rust (Hemileia vastatrix)

Physiological and Molecular Plant Pathology, 2008
Abstract Coffea arabica plants with the S H 5 and S H 4S H 5 genotypes were inoculated with isolates of the coffee orange rust ( Hemileia vastatrix ) races II and VI, in order to establish two incompatible interactions (I 1 and I 2 ) and a compatible one. Both incompatible interactions were characterized by restricted fungal growth associated with

New Races of Hemileia vastatrix Detected in Peruvian Coffee Fields

Agronomy
Coffee leaf rust (CLR), a fungal disease caused by Hemileia vastatrix, represents Peru’s most significant threat to coffee production. The CLR epidemic (2012–2013) led Peru to implement an emergency plan under which coffee plantations underwent renewal using rust-resistant varieties derived from a Timor hybrid (HDT; Coffea arabica × canephora hybrid ...
