Essential Oils and Antagonistic Microorganisms as Eco-Friendly Alternatives for Coffee Leaf Rust Control

Plants, 2023
Coffee leaf rust (CLR) is caused by the biotrophic fungus Hemileia vastatrix Berk. & Br., a disease of economic importance, reducing coffee yield up to 60%. Currently, CLR epidemics have negatively impacted food security.

Isolation and identification of antagonistic fungi on coffee leaf rust in the Dieng highlands of Banjarnegara, Indonesia

Egyptian Journal of Biological Pest Control, 2023
Background Coffee is an important plantation crop in Indonesia. The coffee cultivation process was disrupted due to the fungus Hemileia vastatrix which causes rust disease. Biological control has the potential to suppress disease development.

Infection by Hemileia vastatrix [PDF]

Nature, 1967
RAJENDREN1 has recently published observations on the nuclear life cycle of Hemileia vastatrix in which he describes penetration of the leaf as occurring by means of a “bifid infection peg” produced from an appressorium, which he considers does not lie over a stoma.

Isolation and selection of Hemileia Vastatrix antagonists

European Journal of Plant Pathology, 2014
Organic coffee growing is rapidly increasing in Brazil, and many diseases, especially coffee leaf rust (Hemileia vastatrix), are threatening its production. This study is a first step towards a biocontrol program for coffee rust on organically grown plants.

Correlation Between Secondary Metabolites of Leaf and the Resistance to Leaf Rust (Hemileia vastatrix) on Several Arabica Coffee Clones

Ilmu Pertanian (Agricultural Science), 2019
Indicator of coffee resistance to leaf rust attack (Hemileia vastatrix) is needed to select superior coffee plants resistant to biotic stress. This study aims to find the relationship between the content of secondary metabolites and the intensity of leaf

Leaf Fungal Microbiome Is Modulated by Interspecific Hybridization Events Between Coffea Species. [PDF]

Physiol Plant
ABSTRACT Increasing attention has been given to the host phylogeny and domestication roles in shaping plant‐associated microbiomes. However, the interspecific effects of hybridization on microbial communities remain poorly understood. We investigated the effects of interspecific hybridization on the composition, diversity, ecological organization, and ...

Transcriptome Analysis Uncovers the Gene Expression Profile of Hemileia vastatrix (Race XXXIII) during the Interactions with Resistant and Susceptible Coffee

Agronomy, 2022
Coffee leaf rust is caused by Hemileia vastatrix Berk. and Broome and is the most important coffee disease in all regions where coffee is cultivated. Here, we sought to sequence the transcriptome of H.
