The coffee leaf rust pandemic: An ever‐present danger to coffee production
Plant Pathology, 2023Abstract Coffee leaf rust (CLR) is caused by the biotrophic pathogenic fungus Hemileia vastatrix . Despite being the most researched coffee disease, mysteries still exist relating to its epidemiology and biology.

Coffee Leaf Rust Detection Using Genetic Algorithm
2019 XV Workshop de Visão Computacional (WVC), 2019In Brazil, most of the productive coffee plants is susceptible to rust, a severe disease caused by a pathogenic fungi which attacks the leaves of coffee plants, thus causing a drop in coffee production of up to 45%. To address this problem this paper proposes a genetic algorithm-based solution to identify rust in coffee leaves, thus contributing to a ...

Application of Genome Studies of Coffee Rust
2014The coffee rust, caused by the fungus Hemileia vastatrix, is the most serious disease of this crop worldwide. In Colombia the pathogen causes a reduction in production of up to 30% in susceptible varieties of Coffea arabica, if not controlled mild epidemics can occur and complete crop losses in strong epidemics.

Weather-based coffee leaf rust apparent infection rate modeling
International Journal of Biometeorology, 2018Brazil is the major coffee producer in the world, with 2 million hectares cropped, with 75% of this area with Coffea arabica and 25% with Coffea canephora. Coffee leaf rust (CLR) is one of the main diseases that cause yield losses by reducing healthy leaf area.

Incomplete Resistance to Coffee Leaf Rust
1983Incomplete resistance to Hemileia vastatrix Berk. et Br. has been studied in Brazil under field, greenhouse, nursery and laboratory conditions. The following coffee populations were studied: breeding lines and cultivars of C. arabica, and c. canephora cultivars Kouillou, Icatu andCatimor.

Modelling coffee rust (Hemileia vastatrix)
2009Plant disease epidemiologists have built models in order to describe, explain or predict development of epidemics, taking into account the multiple factors that can affect a disease. Indeed, the existence and severity of a disease are determined by the effects of a host, a pathogen, an environment, a cropping system and their interactions.
