Robust Citrus Disease Diagnosis: A Hybrid CNN Framework for Multi‐Task Classification, Severity Estimation, and Cross‐Species Adaptation

Engineering Reports, Volume 8, Issue 2, February 2026.
We propose a hybrid CNN–ML approach to accurately classify diseases in lemon and orange leaves and assess their severity. Our model achieves high accuracy and demonstrates generalizability, showing promise for automated disease detection and management in citrus crops.

Huanglongbing: possível ameaça à citricultura catarinense?

Agropecuária Catarinense, 2017
Resumo - O Huanglongbing (HLB) é a principal doença dos citros no Brasil. É causado por bactérias do gênero “Candidatus Liberibacter” e transmitido pelo psilídeo-asiático-dos-citros, Diaphorina citri. Os sintomas do HLB são mosqueamento nas folhas (clorose assimétrica no limbo) e amarelecimento de ramos, além de os frutos mostrarem maturação irregular,

Targeting the “bitterness gene” by genome editing abolishes synthesis of bitter flavanones in citrus; prospects for new varieties and extended climates for cultivation

The Plant Journal, Volume 124, Issue 6, December 2025.
SUMMARY Bitterness in citrus fruit is conferred by flavanone‐neohesperidosides, whose accumulation is catalyzed by a single enzyme flavanone‐7‐O‐glucosides‐1,2‐rhamnosyltransferase (1,2RhaT), expressed in both leaves and fruit. To eliminate citrus bitterness, we used CRISPR/Cas9 genome editing to inactivate the 1,2RhaT gene in grapefruit (Citrus ...

Impact of Soil Chemical Attributes on the Behavior and Spread of Fusarium Oxysporum in Date Palm

Plant-Environment Interactions, Volume 6, Issue 5, October 2025.
Mechanisms by which soil elements affect disease expression. ABSTRACT Fusarium wilt of date palm (Phoenix dactylifera L.), caused by Fusarium oxysporum f. sp. albedinis, continues to threaten oases across the Maghreb. However, the disease has failed to establish in Southeastern Algeria, despite the ongoing movement of potentially contaminated plant ...
