Phyllosticta citricarpa and sister species of global importance to Citrus

Molecular Plant Pathology, Volume 20, Issue 12, Page 1619-1635, December 2019., 2019
Summary Several Phyllosticta species are known as pathogens of Citrus spp., and are responsible for various disease symptoms including leaf and fruit spots. One of the most important species is P. citricarpa, which causes a foliar and fruit disease called citrus black spot.

Pest categorisation of Elsinoë fawcettii and E. australis

EFSA Journal, Volume 15, Issue 12, December 2017., 2017
Abstract The Panel on Plant Health performed a pest categorisation of Elsinoë fawcettii and E. australis, the causal agents of citrus scab diseases, for the EU. The identities of the pests are well‐established and reliable methods exist for their detection/identification. The pests are listed in Annex IIAI of Directive 2000/29/EC as Elsinoë spp.

Selecting hyperspectral bands and extracting features with a custom shallow convolutional neural network to classify citrus peel defects

Smart Agricultural Technology, 2023
Citrus Black Spot (CBS) causes considerable damage to the Florida citrus industry. Early detection of CBS, especially in the presence of other peel blemishes, would enable better mapping and control of CBS spread, reduce wasted fruit, and permit early ...

A Comparative Study on Application of Computer Vision and Fluorescence Imaging Spectroscopy for Detection of Huanglongbing Citrus Disease in the USA and Brazil

Journal of Spectroscopy, Volume 2013, Issue 1, 2013., 2013
The overall objective of this work was to develop and evaluate computer vision and machine learning technique for classification of Huanglongbing‐(HLB)‐infected and healthy leaves using fluorescence imaging spectroscopy. The fluorescence images were segmented using normalized graph cut, and texture features were extracted from the segmented images ...

Proteomics of Plant Pathogenic Fungi

BioMed Research International, Volume 2010, Issue 1, 2010., 2010
Plant pathogenic fungi cause important yield losses in crops. In order to develop efficient and environmental friendly crop protection strategies, molecular studies of the fungal biological cycle, virulence factors, and interaction with its host are necessary.

Studies on citrus melanose and citrus stem-end rot by Diaporthe citri (Faw.) Wolf. Part 4. Antifungal substance in melanose spot.

Japanese Journal of Phytopathology, 1986
A series of experiments were conducted to clarify the reason why the invading hyphae of Diaporthe citri (Faw.) Wolf is arrested and killed in melanose spot. After a melanose spot on citrus leaf was formed, pycnospore suspension of D. citri with 2% fructose was inoculated onto the melanose spot.

Citrus Diseases Exotic to Florida: Citrus Tristeza Virus– Stem Pitting (CTV-SP)

EDIS, 2006
Citrus is susceptible to a large number of diseases caused by plant pathogens. Economic losses due to plant diseases can be severe, but fortunately, not all pathogens attacking citrus are present in Florida.

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.

Evaluation of Postinfection Control of Citrus Scab and Melanose with Benomyl, Fenbuconazole, and Azoxystrobin [PDF]

Plant Disease, 2000
Citrus scab, caused by Elsinoe fawcettii, and melanose, caused by Diaporthe citri, are serious diseases of citrus in Florida that reduce the exterior quality of fruits produced for the fresh market. The availability of fungicides with postinfection activity could increase the flexibility of growers in managing these diseases.

Advancements in smart agriculture: A systematic literature review on state‐of‐the‐art plant disease detection with computer vision

IET Computer Vision, Volume 19, Issue 1, January/December 2025.
Plant diseases are known to cause negative impacts and financial losses which are usually found on plant leaves and detection using traditional methods is a labor‐intensive process. Smart agriculture applications based on computer vision are being developed to detect and control of plant diseases.
