A review of Phaeoacremonium species involved in Petri disease and esca of grapevines
Phytopathologia Mediterranea, 2006 The current status of Phaeoacremonium species involved in Petri disease and esca is reviewed. The taxonomical position and classification of Phaeoacremonium as well as its teleomorph, Togninia, are discussed. The review also provides the currently known distribution and host range of Phaeoacremonium species.

First Report of Phaeoacremonium krajdenii Causing Petri Disease of Grapevine in Spain.
Plant Disease, 2007 In September 2009, symptoms of grapevine (Vitis vinifera L.) decline were observed on 3-year-old grapevines in a vineyard in Roquetas de Mar (Almeria Province, southern Spain). Affected vines were weak with reduced foliage and chlorotic leaves. Black spots and dark streaking of the xylem vessels could be seen in cross- or longitudinal sections of the ...

First Report of Phaeoacremonium mortoniae Causing Petri Disease of Grapevine in Spain.
Plant Disease, 2007 In May 2006, symptoms of grapevine decline were observed on 4-year-old grapevines (cv. Cabernet Sauvignon) grafted onto 110 R rootstock in Daimiel (Ciudad Real Province, central Spain). Affected vines had low vigor, reduced foliage, and chlorotic leaves. Cross or longitudinal sections of the rootstock trunk showed black spots and dark streaking of the

FIRST REPORT OF PHAEOACREMONIUM ALVESII ASSOCIATED WITH GRAPEVINE PETRI DISEASE IN IRAN
Journal of Plant Pathology, 2015In June 2013, a survey was conducted for grapevine decline in Abadeh (Fars province, south-western Iran). Branch and trunk samples were collected from grapevines showing Petri disease symptoms, i.e. stunted growth, chlorotic leaves, and necrosis in cross-sectioned wood. Isolations were made from symptomatic wood tissue on malt extract agar (MEA).

First Report of Phaeoacremonium scolyti Causing Petri Disease of Grapevine in Spain. [PDF]
Plant Disease, 2008 In May 2007, a survey was conducted to evaluate the phytosanitary status of grapevine propagating materials in a commercial nursery located in Valencia Province (eastern Spain). Fungal isolation was performed on 25 grafted plants (1-year-old grapevines cv.

Evaluation of fungicides to control Petri disease pathogens in the grapevine propagation process
Crop Protection, 2009 The efficacy of fourteen selected fungicides against Phaeomoniella chlamydospora and Phaeoacremonium aleophilum was evaluated in vitro by mycelial growth and conidial germination assays. Azoxystrobin, carbendazim and tebuconazole were the most effective fungicides against P. chlamydospora, while carbendazim and didecyldimethylammonium chloride were the

Sensitivity of Petri disease pathogens to hot-water treatments in vitro
Annals of Applied Biology, 2008AbstractPetri disease pathogens (Phaeoacremonium spp. and Phaeomoniella chlamydospora) are able to colonize the vessels in the xylem of grapevine propagating material. Hot‐water treatment (HWT) protocols at 50°C for 30 min have been applied in grapevine nurseries to control these pathogens with variable results.

Petri net models and non linear genetic diseases
2010 IEEE Fifth International Conference on Bio-Inspired Computing: Theories and Applications (BIC-TA), 2010Understanding how an individual genetic make-up influences their risk of diseases, is a problem of paramount importance. Although machine-learning techniques are unable to uncover the relationships between genotype and disease, we can still build the best biochemical model automatically with the help of methods that identify the DNA sequence variations

In order to improve our understanding of directly transmitted pathogens within host populations, epidemic models should take into account individual heterogeneities as well as stochastic fluctuations in individual parameters. The associated cost results in an increasing level of complexity of the mathematical models which generally lack consistent ...
