Using Copper in Organic Viticulture: Doing it best with less? [PDF]
, 2007 For many years, applications of copper fungicides have been used to control downy mildew on grapes. Nowadays, its intensive use is under consideration due to ecotoxicological aspects, especially in organic viticulture.

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.

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

Development of an Organic Table Grape Production and Market in Switzerland [PDF]
, 2008 In Switzerland there is an increasing consumer demand for residue-free, organic table grapes. The organic cultivation of table grapes, however, is very delicate in humid climates and experience to advice organic growers is still lacking.

Pest Management Science, EarlyView.RNA interference (RNAi) technologies, host‐induced gene silencing (HIGS) and spray‐induced gene silencing (SIGS), potentially offer sustainable crop protection. However, efficacy, costs, regulatory clarity, and socio‐environmental impacts require further evaluation for broader use.

Efficacy testing of novel organic fungicides and elicitors: from the lab to the field [PDF]
, 2006 Novel organic fungicides and elicitors against downy mildew on grapevines were evaluated on grapevine seedlings in a series of indoor screening experiments under controlled conditions and, if they have shown a good efficacy indoors, in a screening ...

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 ...
