First Report of Alternaria Brown Spot of Citrus Caused by Alternaria alternata in Peru

Plant Disease, 2006
Alternaria brown spot, caused by Alternaria alternata (Fr.) Keissler, causes leaf, twig, and fruit lesions and reduces yield and fruit quality of many tangerines (Citrus reticulata Blanco) and their hybrids (3). In 2003, characteristic symptoms of brown spot were observed on young leaves and fruit of ‘Minneola’ tangelo in the Satipo Province of Peru ...

Endopolygalacturonase Is Essential for Citrus Black Rot Caused byAlternaria citribut Not Brown Spot Caused byAlternaria alternata [PDF]

Molecular Plant-Microbe Interactions®, 2001
Alternaria citri, the cause of Alternaria black rot, and Alternaria alternata rough lemon pathotype, the cause of Alternaria brown spot, are morphologically indistinguishable pathogens of citrus: one causes rot by macerating tissues and the other causes necrotic spots by producing a host-selective toxin.

First Report of Alternaria Brown Spot of Minneola Tangelo in Turkey [PDF]

Plant Disease, 1997
Minneola tangelo, a hybrid of Dancy tangerine and Duncan grapefruit, is widely grown in Turkey for export to Europe. In 1995, 2,000 ha of diseased Minneola tangelo trees were observed in the Cukurova region. Ninety percent of orchards in this region were diseased but disease severity depended upon the location and the disease control strategies ...

How does leaf age affect performance? A comparative study of essential oils from young and mature Eucalyptus globulus leaves in crop protection

Pest Management Science, EarlyView.
Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.
