Hemileia vastatrix in Coffea spp.: Distribution of Urediniospores Grouped by Size and Insights into Morphological Structures [PDF]

Journal of Fungi
Hemileia vastatrix coffee leaf rust reduces Mexican coffee production by 51%. We aimed to analyze the size and distribution of H. vastatrix urediniospores among coffee plantations, as well as the morphological structures of the uredinium.

The Big Rust and the Red Queen: Long-Term Perspectives on Coffee Rust Research [PDF]

Phytopathology®, 2015
Since 2008, there has been a cluster of outbreaks of the coffee rust (Hemileia vastatrix) across the coffee-growing regions of the Americas, which have been collectively described as the Big Rust. These outbreaks have caused significant hardship to coffee producers and laborers. This essay situates the Big Rust in a broader historical context.

Interactive effects of altitude, microclimate and shading system on coffee leaf rust [PDF]

Journal of Plant Interactions, 2019
Shade effects on coffee diseases are ambiguous because they vary depending on the season and environment. Using Coffee Leaf Rust (CLR) as an example, we demonstrate relationships between the environment and shading systems and their effects on disease ...
