Characterization of the horizontal resistance of coffee (Coffea arabica) to yellow rust (Hemileia vastatrix) in the field and laboratory por Paredes Espinosa, Richard, Mansilla Córdova, P. J., Abad Romaní, Yudi Gertrudis, Gutiérrez Reynoso, Dina Lida, Guerrero Abad, Juan Carlos, Egoávil, G.

“…The objective of the study was to evaluate the incidence and severity of epidemic conditions in the field and characterize the components of horizontal resistance, using the method of inoculations of H. vastatrix in separated coffee leaves in the laboratory. The epidemiological results collected from the field indicate that 12.43 and 20.71% of the genotypes showed complete and incomplete resistance, respectively; 66.86% showed high susceptibility to the pathogen. …”

First Molecular Evidence of Theileria and Anaplasma Genospecies in Subulo gouazoubira Exhibiting Clinical Symptoms from Entre Ríos Province, Argentina por Sebastian, Patrick, Vaschalde, Paula Josefina, Pelosi, María Celeste, Flores, Fernando Sebastián, Yedro, Julio, Tarragona, Evelina Luisa

“…However, the pathogenicity of these strains and specific role of S. gouazoubira in their enzootic transmission cycles remains unclear. To improve epidemiological understanding, assess risks and develop targeted control strategies, future studies should prioritize the isolation, characterization and cultivation of these genospecies and the assessment of vector competence.…”
