Standard Area Diagram Design Determines Accuracy, Speed and Sampling Efficiency in Coffee Leaf Rust Assessment

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
A new two‐colour 10‐diagram standard area diagram (SAD) for coffee leaf rust was developed and validated in both laboratory and field environments, and compared with previous true‐colour 21‐diagram SAD. Overall, a simplified SAD preserved statistical performance while improving operational efficiency, enabling the same level of precision with reduced ...

Cytological Studies on Germinating Teliospores ofHemileia Vastatrix [PDF]

Caryologia, 1965
SUMMARYMeiosis in the teliospores of Hemileia vastatrix is seen to differ from the rust fungi where the basidium is external. The chromosome number is larger than has been reported for most of the Basidiomycetes. The irregularities recorded under natural conditions suggest some disturbance in the important phase in the life cycle of the fungus ...

Association of Agro‐Morphological Traits With Cup Quality in Accessions of Coffea arabica L. From the INIA Germplasm Bank, Peru

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT In recent years, Peruvian coffee production has increasingly focused on specialty coffees, with cup quality (CQ) as a key criterion. While previous studies have characterized the Coffee Germplasm Collection of the National Institute of Agrarian Innovation (CGC‐INIA), few studies have analyzed coffee cup quality.

Thermal sensitivity and yield of Arabica coffee under climatic variability

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Coffee yield is influenced by climatic factors, with temperature and water availability being key determinants. This study aimed to evaluate the effects of climate variability on the yield of Arabica coffee (Coffea arabica L.) cultivars across phenological phases and to validate an agrometeorological model at local and regional scales using ...

Nano‐Encapsulated Cinnamomum cassia Essential Oil in Combination With Fluconazole Exhibits Synergistic Activity Against Fluconazole‐Resistant Nakaseomyces glabratus and Pichia kudriavzevii

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Nano‐encapsulated Cinnamomum cassia essential oil (nano‐CC‐EO) showed in vitro antifungal activity against fluconazole‐resistant Nakaseomyces glabratus and Pichia kudriavzevii clinical isolates. Checkerboard assays revealed synergistic or additive interactions between nano‐CC‐EO and fluconazole in several isolates, without evidence of antagonism. These
