The life cicle of Plasmopara viticola

, 2000
Plasmopara viticola (Berk. & M. A. Curtis) Bed. & De Toni is an obligate biotrophic oomycetous organism which causes downy mildew of grape vine. An understanding of its life-cycle is essential in relation to the pathology and epidemiology, and for the development of better control of the disease. It overwinters as oospores within fallen leaves.

Sensibilità al cymoxanil di Plasmopara viticola

, 2015
NELLE ANNATE comprese tra il 2009 e il 2011 è stato eseguito il monitoraggio della sensibilità al cymoxanil in 25 popolazioni di Plasmopara viticola (Berk. et Curt.) Berlese e De Toni prelevate in diverse regioni italiane. Nelle prove cymoxanil ha inibito completamente la germinabilità delle oospore alla concentrazione di 120 mg/L (dose di impiego ...

STUDI EPIDEMIOLOGICI SU PLASMOPARA VITICOLA

, 2010
Plasmopara viticola Berl. et De Toni è l’agente causale della peronospora della vite. Le epidemie di questo Oomicete pos- sono causare perdite di produzione gravissime e scadimento della qualità in tutte le aree di coltivazione caratterizzate da pri- mavere miti e piovose.

Long-term survival of Plasmopara viticola oospores

, 2011
A research was carried out in order to verify the long-term viability of Plasmopara viticola oospores. It is commonly assumed that oospores may survive across grapevines growing seasons, but no experimental evidence of this assumption has been provided to date. Grapevine leaves were collected from untreated plants in Emilia-Romagna in fall 2004 to 2008.

Occupational sensitization to Plasmopara viticola

Journal of Allergy and Clinical Immunology, 1994
Molds of the class of Oomycetes are of allergologic importance in special cases. However, probes are not commercially available for diagnostic purposes. Our case report is based on the medical history of a greenhouse worker who had atopic syndrome. He handled pure cultures of defined fungi and plants.

Evolution of Qol resistance in Plasmopara viticola oospores

European Journal of Plant Pathology, 2010
QoI resistance in P. viticola was first detected in France and Italy in 1999. Molecular and biological assays have been carried out since 2000 in order to provide reliable methods of detecting and quantifying resistance. Oospores were collected in vineyards located in northern and southern Italy.

Assessment of QoI resistance in Plasmopara viticola oospores

Pest Management Science, 2006
AbstractQoI fungicides, inhibitors of mitochondrial respiration at the Qo site of cytochrome b in the mitochondrial bc1 enzyme complex, are commonly applied in vineyards against Plasmopara viticola (Berk. & MA Curtis) Berl. & De Toni. Numerous treatments per year with QoI fungicides can lead to the selection of resistant strains in the pathogen

An agrometeorological approach for the simulation of Plasmopara viticola

Computers and Electronics in Agriculture, 2008
Agrometeorology can be applied to the analysis and modelling of plant disease development and creating a decision-support system for the operational management of crop protection. An approach for the simulation of grapevine (Vitis vinifera) downy mildew (Plasmopara viticola) is described in this paper. Mathematical models for grapevine leaf area growth

Protease inhibitors decrease the resistance of Vitaceae to Plasmopara viticola

Plant Physiology and Biochemistry, 2012
Plasmopara viticola must successfully infect susceptible grapevine cultivars to complete its biological cycle. In resistant grapevine varieties, P. viticola is blocked by the activation of defense mechanisms; these defense mechanisms produce hypersensitive reactions, which are related to programmed cell death.
