Pest Management Science, EarlyView.The findings of this study indicate that powdery mildew control achieved with the pneumatic solid set canopy delivery system (PSD‐SSCDS) was comparable with that of a conventional airblast sprayer. These results highlight the PSD‐SSCDS as a promising alternative spray technology. Abstract BACKGROUND In this study, a previously optimized pneumatic spray

Behavior of grape breeding lines with distinct resistance alleles to downy mildew (Plasmopara viticola) [PDF]
Crop Breeding and Applied Biotechnology, 2017 Downy mildew (Plasmopara viticola) is the main grapevine disease in humid regions. In the present investigation, marker-assisted selection (MAS) was used to develop grapevine lines homozygous in loci Rpv1 and Rpv3 for resistance against P. viticola. The

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.

Eucalyptus staigeriana essential oil can control downy mildew in grapevine
Pesquisa Agropecuária Gaúcha, 2021 Downy mildew (Plasmopara viticola) is the primary disease in viticulture worldwide, and your control requires synthetic fungicides applications to avoid quality and yield loss in the grapevines.

Alternatives to copper-based treatments for the control of grapevine downy mildew (Plasmopara viticola): 5-year synthesis of trials in France and Italy [PDF]
, 2010 The objective of the UE-funded program REPCO (FP6) was to identify new alternatives to copper fungicides in organic farming. Two pathogens have been considered: grapevine downy mildew (Plasmopara viticola) and apple scab (Venturia inaequalis).

Factors Affecting the Vineyard Populational Diversity of Plasmopara viticola [PDF]
The Plant Pathology Journal, 2019 Vitis vinifera is very susceptible to downy mildew (Plasmopara viticola). A number of authors have suggested different genetic populations of this fungus exist in Europe, each showing a different degree of virulence. Work performed to date indicates this diversity to be the result of different factors.

Plant Biology, EarlyView.Pre‐treatment of grapevine plants with oregano essential oil vapour alleviates downy mildew susceptibility by accumulation of monoterpenol glycosides. Abstract Grapevine downy mildew, caused by the oomycete Plasmopara viticola, is a destructive disease that causes major economic losses as most elite grapevine cultivars are susceptible to this pathogen.
