Elucidating R‐gene‐mediated resistance to wheat dwarf virus in Triticum aestivum genotypes
Annals of Applied Biology, Volume 188, Issue 3, Page 947-961, May 2026.This study investigates R‐gene‐mediated resistance to wheat dwarf virus (WDV) among different wheat genotypes. Following inoculation with Psammotettix alienus (leafhoppers) and the subsequent appearance of characteristic symptoms such as yellowing and dwarfing, phenotypic responses were evaluated alongside molecular analyses, including quantification ...

Journal of Phytopathology, Volume 174, Issue 3, May/June 2026.ABSTRACT Foliar fungicides are widely used in maize production in southern Brazil, yet their economic justification under low disease pressure remains uncertain. We synthesised yield and economic responses to a fungicide programme using a random‐effects meta‐analytic approach based on 19 multi‐environment trials conducted across the first and second ...
