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 pests in a global world

, 2020
Citrus pest management has evolved from a primarily biological approach to dependence on chemical control, followed by more integrated systems. More recently, the spread of huanglongbing (HLB) or citrus greening disease in Asia and both Americas has ...

Studies on Citrus Melanose Disease of Satsuma Orange

Japanese Journal of Phytopathology, 1973
In October 1969, the perithecia of citrus melanose fungus, Diaporthe citri (Fawc.) Wolf, were found in the orchard of Satsuma orange in Kanagawa Prefecture. The author conducted experiments to know the time and environmental conditions on perithecia formation, and also to ascertain the virulence of ascospores against citrus fruits comparing with that ...

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.

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.
