The effect of Saccharomyces cerevisiae on antioxidant system of grape leaves infected by downy mildew

BIO Web of Conferences, 2020
In this article, results of the comparative analysis and assessment of resistance of two grape cultivars Vostorg and Muscat blanc against downy mildew disease (Plasmopara viticola) with or without the symbiote Saccharomyces cerevisiae (vine yeast) were ...

Susceptibility of Cold-Climate Wine Grape Cultivars to Downy Mildew, Powdery Mildew, and Black Rot [PDF]

Plant Disease, 2017
Lack of knowledge regarding the susceptibility of cold-climate hybrid wine grape cultivars may be leading to the overuse of fungicides and underutilization of plant host resistance to combat disease in the northern United States. To provide new insights on diseases of cold-climate cultivars and to update management recommendations, disease was ...

Downy mildew is able to carry out its sexual cycle on resistant grape varieties

IVES Technical Reviews, 2020
Previous studies have shown that new resistant grape cultivars limit epidemics caused by asexual reproduction of downy mildew. However, until now, there was a lack of knowledge on the sexual phase of the pathogen.

An annotated image dataset of downy mildew symptoms on Merlot grape variety

Data in Brief, 2021
This article introduces a dataset of high-resolution colour images of grapevines. It contains 99 images acquired in the vineyard from a cruising tractor. Each image includes the full foliage of a grapevine plant. These images display a diverse range of symptoms caused by the grapevine downy mildew (Plasmopara viticola), a major fungal disease.

Marker-assisted pyramiding of resistance loci to grape downy mildew [PDF]

Pesquisa Agropecuária Brasileira, 2018
Abstract: The objective of this work was to use a marker-assisted selection for pyramiding the resistance loci Rpv1 and Rpv3.1 in grapevine (Vitis vinifera), and to evaluate their conferred resistance against Brazilian downy mildew (Plasmopara viticola) isolates. A progeny of 23 plants, segregating for the two resistance loci, was obtained by the cross

IMPROVED DOWNY MILDEW CONTROL IN WINE GRAPES WITH VOSSEN BLUE [PDF]

HortScience, 1992
Downy Mildew, Plasmopara viticola, causes major damage and economic loss to many wine grape cultivars grown in the Northeast. The purpose of the experiment was to test the efficacy of Vossen Blue (VB; iron pigment) in association with fungicides for the control of Downy Mildew disease of wine grapes in New Jersey.

Genome analyses of the sunflower pathogen Plasmopara halstedii provide insights into effector evolution in downy mildews and Phytophthora. [PDF]

, 2015
BACKGROUND: Downy mildews are the most speciose group of oomycetes and affect crops of great economic importance. So far, there is only a single deeply-sequenced downy mildew genome available, from Hyaloperonospora arabidopsidis.

Screening and Validation of SSR Molecular Markers for Identification of Downy Mildew Resistance in Intraspecific Hybrid F₁ Progeny (V. vinifera)

Horticulturae, 2022
Downy mildew is a major disease that severely restricts the healthy and sustainable development of the global grape and wine industry, so there is significant interest in breeding high-quality disease-resistant varieties. In this study, hybridization was

Use of beneficial bacteria and their secondary metabolites to control grapevine pathogen diseases [PDF]

, 2013
Grapevine is one of the most important economic crops yielding berries, wine products as well as derivates. However, due to the large array of pathogens inducing diseases on this plant, considerable amounts of pesticides—with possible negative impact on
