Efficacy of using grape cane extracts against Plasmopara viticola under field conditions and their impact on the composition of berries and musts of Vitis vinifera L. cv. Riesling

OENO One
Grapevine downy mildew caused by Plasmopara viticola is a deleterious vine disease currently controlled using synthetic and copper-based fungicides. Environmental concerns surrounding such fungicides necessitate sustainable alternatives like grape cane ...

CRISPR/Cas‐Mediated Gene Editing in Plant Immunity and Its Potential for the Future Development of Fungal, Oomycete, and Bacterial Pathogen‐Resistant Pulse Crops

Plant, Cell &Environment, EarlyView.
ABSTRACT Pulses provide myriad health benefits and are advantageous in an environmental context as a result of their leguminous nature. However, phytopathogenic fungi, oomycetes and bacteria pose a substantial threat to pulse production, at times leading to crop failure.

Volatile organic compounds of hoary stock are responsible for suppressing downy mildew of grape in an intercropping system

Phytopathology Research
Grape downy mildew (Plasmopara viticola) is an air-borne disease and difficult to control. It has been observed that intercropping grapevines (Vitis vinifera) with aromatic plants can effectively suppress the airborne disease and volatile organic ...

Transcriptional Profiling of Resistant and Susceptible Cultivars of Grapevine (Vitis L.) Reveals Hypersensitive Responses to Plasmopara viticola

Frontiers in Microbiology, 2022
Grapevine downy mildew is the most serious disease of grapevine cultivars that affects the rate of resistance/susceptibility to Plasmopara viticola. In this study, we used the susceptible cultivar “Zitian Seedless” and the resistant cultivar “Kober 5BB ...

Phylogenomics of Plasmopara halstedii Reveals Genomic Regions Associated With the Breakdown of Sunflower Downy Mildew Resistance Genes

Molecular Ecology, Volume 35, Issue 4, February 2026.
ABSTRACT Understanding the genetic diversity and evolutionary history of plant pathogens is crucial for effective disease management strategies. Sunflower downy mildew, caused by the oomycete Plasmopara halstedii, is a worldwide threat to the sunflower oil crop.

Susceptibility to downy mildew in grape clusters: New microscopical and biochemical insights

Plant Physiology and Biochemistry, 2012
Grape clusters of different Vitis genotypes, including Vitis vinifera cvs Chasselas and Merlot, and two interspecific grape varieties, Solaris (cvs. Merzling* x (Saperavi severneyi x Muscat ottonel)) and 2091 (cvs. Gamaret x Bronner), are susceptible or resistant to downy mildew.

EVALUATION OF THE EFFECTIVENESS OF NATURAL ALTERNATIVE COPPER PRODUCTS AND LOW RATE COPPER FORMULATIONS AGAINST GRAPE DOWNY MILDEW IN ORGANIC VITICULTURE [PDF]

, 2007
The control of pathogenic fungi, especially downy mildew, represents the main problem in organic viticulture as only few fungicides, above all copper salts, can be used. As the copper causes problems of environmental impact, the Regulation EC n. 473/2002
