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

open access: yesJournal 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 ...

Weather‐Driven Ensemble Logistic Models for Predicting Fusarium Head Blight of Wheat in Brazil

open access: yesPlant Pathology, Volume 75, Issue 3, May–June 2026.
Functional data analysis identified key post‐flowering weather variables influencing Fusarium head blight (FHB) epidemics in southern Brazil. Logistic and ensemble models integrating these predictors achieved high discrimination (AUC ≤ 0.84). Economic evaluation showed fungicide use was profitable (NMB > 80%) above 0.45 risk probability, supporting ...

Four Novel Colletotrichum Species Associated With Anthracnose of Ornamental Araceae in Brazil With Insights Into Their Host Range

open access: yesPlant Pathology, Volume 75, Issue 3, May–June 2026.
Five ornamental Araceae with anthracnose symptoms, collected in Brazil, yielded four new species of Colletotrichum. These were described and named. Cross‐inoculations of those species on six aroids showed them to be non‐specific. ABSTRACT Araceae includes numerous flowering plant species that are cultivated as ornamentals in gardens, pots or by the cut‐

Foundation Model‐Assisted Segmentation Enables Robust Field‐Based Severity Estimation: A Case‐Study of Coffee Leaf Rust

open access: yesPlant Pathology, Volume 75, Issue 3, May–June 2026.
Foundation model‐assisted segmentation enables accurate field estimation of coffee leaf rust severity. Using 1285 images and curated lesion masks, we compared SAM3, SAM2, DeepLabV3+ and classical threshold methods. SAM3 achieved the highest segmentation accuracy and best agreement with reference severity, demonstrating reliable, scalable disease ...

Laboratory Protocols for Candidatus Liberibacter asiaticus Transmission Biology and Management Research

open access: yesCurrent Protocols, Volume 6, Issue 4, April 2026.
Abstract Candidatus Liberibacter asiaticus (CLas), the causal agent of Huanglongbing, is transmitted by the Asian citrus psyllid (Diaphorina citri) in a persistent, propagative manner. Reproducible transmission studies require not only controlled inoculation assays but also standardized propagation of citrus host plants, maintenance of D.
