Epidemiology of grape downy mildew in 2009 and 2010

Gradus, 2020
Plasmopara viticola is one the most important diseases of grapevine in Hungary. It is present in all grape yards, and growers have to spray regularly if they want to have a healthy crop. Downy mildew can cause epidemic depending on the environmental factors of the year. In this paper I compare the disease occurrence in an epidemic and an average year.

Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca

PLANTS, PEOPLE, PLANET, EarlyView.
The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

Sensitivity of Irish Pyrenopeziza brassicae populations to methyl benzimidazole carbamate (MBC), quinone outside inhibitor (QoI) and succinate dehydrogenase inhibitor (SDHI) fungicides

Pest Management Science, EarlyView.
For three collections of Irish Pyrenopeziza brassicae populations fungicide sensitivity status to methyl benzimidazole carbamate (MBC), quinone outside inhibitor (QoI) and succinate dehydrogenase inhibitor (SDHI) fungicides was determined using sensitivity screening in vitro. Molecular mechanisms of insensitivity have been identified for MBC and QoI in

Results from new fungus-tolerant grapevine varieties for Organic Viticulture [PDF]

, 2000
Two red and three white new fungus-tolerant grape varieties were tested within a period of five years. REGENT, RONDO, JOHANNITER and Gf 48-12 show a better wine quality than PINOT NOIR or SILVANER and can be recommended for Organic Viticulture as well ...

A Novel Grape Downy Mildew Resistance Locus fromVitis rupestris [PDF]

American Journal of Enology and Viticulture, 2020
The viticulture industry needs advanced grape cultivars with genes that enhance disease resistance and environmental stress tolerance to meet the challenges of a changing climate. To discover beneficial allelic variants of grape genes, we established an F1 mapping population from a cross between two North American grapevines, Vitis rupestris Scheele ...

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

Pest Management Science, EarlyView.
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 ...

Evaluation of electrolyzed water to control fungal trunk pathogens in grapevine nurseries

Pest Management Science, Volume 81, Issue 4, Page 1740-1751, April 2025.
Electrolyzed water treatments could have promising applications in the grapevine nursery process to prevent or reduce infections caused by fungal trunk pathogens on grapevine propagation material. Abstract BACKGROUND Grapevine producers demand solutions to control fungal trunk pathogens (FTPs) in nurseries.

Response of hybrid grapes (Vitis spp.) to two biotic stress factors and their seedlessness status

Open Life Sciences
Grape varieties belonging to the Vitis vinifera species are widely grown worldwide, and many of these are susceptible to powdery mildew and downy mildew. However, wild Vitis species are pretty resistant to these diseases.

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 ...
