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

Reducing copper inputs through integration of essential oil‐based formulations: laboratory and 2‐year vineyard evaluation against Plasmopara viticola

Pest Management Science, EarlyView.
Combining an essential oil (EO)‐based formulation with copper effectively controls Plasmopara viticola. Field trials showed a 92–99% protection with lower copper inputs, achieving a 45% copper reduction without compromising efficacy. This approach supports EO‐based products as sustainable alternatives for grapevine downy mildew management.

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 ...

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

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

Antimicrobial properties of tannin extracts against the phytopathogenic oomycete Plasmopara viticola

OENO One
Downy mildew (Plasmopara viticola) is one of the most devastating diseases for European grapevines (Vitis vinifera L.), requiring extensive use of copper-based or synthetic pesticides.
