Identification of Lipid Markers of Plasmopara viticola Infection in Grapevine Using a Non-targeted Metabolomic Approach [PDF]

Frontiers in Plant Science, 2018
The Oomycete Plasmopara viticola is responsible for downy mildew, which is one of the most damaging grapevine diseases. Due to the strictly biotrophic way of life of P. viticola, its metabolome is relatively poorly characterized.

Hyperparasitism on Plasmopara viticola by Simplicillium lanosoniveum [PDF]

PhytoFrontiers™, 2022
A previously unknown association between Plasmopara viticola, the causal pathogen of grape downy mildew, and the mycoparasite strain F2 is described in this paper. F2 could be consistently isolated from the mildew of diseased spots on grape leaves of Kyoho ( Vitis labrusca × V. vinifera cv. Kyoho) infected with P. viticola but not from the surfaces of

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.

Management of Plasmopara viticola : From the Tradition to the Innovation

Plant Health Cases
Abstract This case explores grapevine downy mildew caused by Plasmopara viticola by examining its life cycle and impact on viticulture. It also briefly discusses the challenges and importance of breeding resistant grapevine varieties.

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola). [PDF]

Pest Manag Sci
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

Origin and pathogenicity variation of <i>Plasmopara viticola</i> in China. [PDF]

Front Microbiol
Grapevine downy mildew caused by Plasmopara viticola (Pv) is one of the most devastating diseases of grapevine in China. To understand the origin and pathogenicity of Chinese Pv, a total of 193 single-sporangiophore isolates were obtained from 14 Chinese major viticulture areas.

THE SUSCEPTIBILITY OF TOKAY VINE VARIETIES TO ERYSIPHE NECATOR SCHWEIN.,AND PLASMOPARA VITICOLA (BERK. M.A.CURTIS) BERL. DE TONI. [PDF]

Journal of Central European Agriculture, 2012
On defined production sites in the closed Tokay region only three varieties (cv. Lipovina, cv. Yellow Muscat and cv. Furmint) were grown for several centuries. Objective of the research from 2005-2008 was to examine whether there is a change in varieties
