Development and Validation of a Standard Area Diagram Set of Leaf Rust Severity in Mulberry (Morus nigra L.)

Journal of Phytopathology, Volume 174, Issue 5, September/October 2026.
ABSTRACT Standard area diagrams sets (SADS) are useful tools to improve accuracy and reliability of the estimates of disease severity in many pathosystems. This study developed and validated a SADS for quantifying the severity of mulberry leaf rust, caused by Cerotelium fici. The proposed scale is composed of eight images representing increasing levels

Contribution of Fallen Leaves to Primary Inoculum and the Progress of Glomerella Leaf Spot in Apple Orchards

Journal of Phytopathology, Volume 174, Issue 4, July/August 2026.
ABSTRACT Glomerella leaf spot (GLS), caused by Colletotrichum spp., persists between seasons mainly in fallen leaves on the orchard floor and in dormant plant tissues, which act as primary inoculum sources for disease initiation in spring. Because early epidemic development is strongly dependent on the availability of primary inoculum, practices such ...
