Molecular Identification of Fusarium Species Associated With Coffee Plantations in Bolivia

Journal of Phytopathology, Volume 174, Issue 4, July/August 2026.
ABSTRACT Fungal species associated with coffee and their pathogenic potential remain underexplored in Bolivia. This study aimed to investigate the diversity of Fusarium species associated with coffee in the Amazon basin of Caranavi province in the Yungas region of Bolivia and their ability to induce disease symptoms under controlled conditions. A total

Inoculation and Evaluation of Hemileia vastatrix Under Laboratory Conditions

, 2023
AbstractThe coffee leaf rust, a disease caused by the biotrophic fungusHemileia vastatrix, is one of the main limitations in coffee production today as it causes significant economic losses to the coffee production sector. Genetic improvement is an option to solve these problems.

Incidence-Severity Relationships in the Pathosystem Coffea arabica-Hemileia vastatrix [PDF]

Plant Disease, 1999
Incidence-severity relationships for coffee rust were studied to determine if the easily assessed incidence could be used to evaluate host resistance and fungicide treatment. At two locations in each of 3 years, the incidence of rust on 300 leaves was compared with two assessments of severity: (i) the average number of sporulating pustules per leaf ...

Secondary Metabolites of Calonectria hemileiae Inhibit Hemileia vastatrix Urediniospore Germination: Evidence for Chemical Mediation in a Mycoparasitic Interaction

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
Calonectria hemileiae, an antagonist of the coffee leaf rust pathogen Hemileia vastatrix, produces low‐molecular weight secondary metabolites that inhibit urediniospore germination. These metabolites likely mediate interfungal interactions and show potential for the development of biofungicides against coffee leaf rust.
