Seasonal Development of Ontogenic Resistance to Downy Mildew in Grape Berries and Rachises [PDF]
Clusters of Vitis vinifera and V. labrusca are reported to become resistant to Plasmopara viticola at stages of development ranging from 1 to 6 weeks postbloom. It has been suggested that resistance is associated with loss of the infection court as stomata are converted to lenticels, but the time of onset, cultivar variation, and seasonal variation in

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

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

Epidemiology of grape downy mildew in 2009 and 2010
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.

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

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

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
