When Does Fungicide Use Pay Off in Maize? Evidence From Low Foliar Disease Pressure Environments in Southern Brazil

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 ...

‘Candidatus Liberibacter asiaticus’ Effector SDE4250 Targets Citrus Proteasome Protein RPN10 to Inhibit Salicylic Acid‐Mediated Citrus Immunity

Molecular Plant Pathology, Volume 27, Issue 5, May 2026.
SDE4250 suppressed 26S proteasome activity by targeting CsRPN10 and enhancing its degradation via the proteasome pathway. This impairment of proteasome function subsequently attenuates SA‐mediated defence responses, thereby increasing citrus susceptibility to promote CLas infection.
