The spatial distributions of grape plants with symptoms grapevine leafroll in nine vineyards the Galician wine-growing region Rías Baixas (northwestern Spain) were analyzed. In five, significant aggregations diseased and/or disease gradients toward one borders plots constituted indirect evidence vector transmission by a nonflying vector. From 1991 to 1995, vines from two tested for associated virus 3 (GLRaV-3) enzyme-linked immunosorbent assay. these vineyards, which had been virus-free when...
Abstract Experiments were carried out in the laboratory to assess insecticidal effect on Myzus persicae Sulzer of different oils applied alone or combined with imidacloprid pirimicarb. The tested a horticultural mineral oil, refined rapeseed soya oil and raw fish oil. When sprayed pepper plants infested M. , caused highest mortality aphids (over 80%). Applied before aphid infestation leaves mixture low doses (at one‐fifth dose recommended by manufacturer) pirimicarb one‐tenth manufacturer),...

SummaryMineral oils are widely used to control non-persistently transmitted viruses by aphid vectors, but mineral cause a number of problems including significant phytotoxicity. This study comprises three series assays compare oil, fish oil and four vegetable for: a) insecticidal effects on the Myzus persicae; b) inoculation cucumber mosaic virus (CMV) M. persicae oil-sprayed pepper plants; c) acquisition CMV from plants. The tested were raw refined rapeseed soya oil. showing strongest...
Arabis mosaic virus (ArMV; genus Nepovirus, family Comoviridae) is one of several nepoviruses responsible for infectious degeneration disease grapevines in Europe (3). The first occurrence Spain, the summer 2007, was found Val de Salnés, Rias Baixas appellation, Galice on 25-year-old vines Albariño variety grafted onto an unidentified rootstock and showing leaf yellowing. second finding spring 2008 Barriobusto, Rioja Basque Country 30-year-old Tempranillo 41B rootstock. In this case, no...
Grapevine leafroll disease (GLD) is caused by one or more of the leafroll-associated viruses (GLRaVs). GLD’s symptoms are expected to be evident in indicator cultivars, regardless GLRaV(s) involved. In present study, incidence (I) and severity (S), before veraison (Sy < V), a index (DSI) an earliness (EI) (2013–2022) were recorded order examine factors affecting evolution GLD Pinot noir graft inoculated with scions infected GLRaV-3 that, origin, showed diversity symptoms. Strong...
Grapevine leafroll‐associated virus 3 ( GLR aV‐3; Ampelovirus , Closteroviridae ) isolates from Galicia in northwestern Spain were selected to characterize their genetic diversity according different factors (age, origin, location, variety, etc.). The vines belonged either local white and red varieties autochthonous or other Spanish regions but widely used Galicia. These aV‐3 came vineyards located coastal inner areas. Multiplex RT ‐ PCR allowed the detection of belonging groups I, II, III–V...
Abstract The mealybug Planococcus ficus is one of the main vectors Grapevine leafroll associated virus-3 (GLRaV-3), which was commonly detected in cv “Albariño” planting material before certified stock available. Mealybug infestations were rare vineyards southern Galicia (NW Spain) during 1990s (2.2% surveyed) and are still inland zones. However, have spread since 2000, with 15% surveyed infested 2004 80% 2016. spatial temporal distributions plants infected GLRaV-3 quantified over a 30-year...
The effect of leaf removal treatments around vine cluster zones on must quality were tested during 2003 and 2004 in Rias Baixas (Spain) two Albarino vineyards infected by GLRaV-3. As expected, the main virus damage was decreased sugar content (2.1 Brix 0.9 2004) musts compared with leafroll-free plants. Leaf improved decreasing titratable acidity between 0.5 1.9 g L-1 tartaric acid, depending experiment; it also increased grape an average 1 Brix. In high incidence GLRaV-3, partial...
Protected geographical indications (PGIs) share health problems related to plant propagation material. The PGI “Faba de Lourenzá” encompasses a 1660 km2 area in northern Galicia, Spain, renowned for its Galaica” (FG) and Faba do marisco” (FM) bean cultivars. lack of certified virus-free seeds poses challenge. From 2019 2023, from 60 lots were tested BCMV. Plants several plots periodically develop disease progress curves (DPCs). Control methods (plots out zone, seedlings, rogueing, corn...
Laboratory, greenhouse and field experiments were performed on vegetable, fish mineral oils to evaluate their phytotoxic effects grapevine effectiveness in the control of powdery mildew. None tested showed detectable at concentrations 2% or less applied up to 4 times per week. In trials, efficacy paraffin oil, refined rapeseed oil partially against powdery mildew was similar that obtained with standard fungicides (tebuconazole colloidal sulphur). In field three (paraffin crude soya oil:...
Grapevine trichovirus A (GVA), a flexuous, filamentous, phloem-limited virus with an approximately 7.3-kbp RNA genome, is widespread in grapevines showing symptoms of leafroll and/or rugose wood. The can be mechanically inoculated to Nicotiana benthamiana and N. clevelandii. field survey diseased Vitis vinifera white red cultivars was carried out Pontevedra (northwest Spain) during the autumn 1993. We detected presence GVA vines by immunocapture-reverse transcription-polymerase chain...
