L’objectif du plan Ecophyto, lancé suite au Grenelle de l’Environnement en 2008, est de diminuer les applications de phytosanitaires, tout en assurant un niveau de production élevé tant en quantité qu’en qualité.

INFOGM 12/09/19 Oïdium et mildiou : des vignes multi-résistantes... sans OGM

Une des pistes, pas la seule on le verra, pour les semenciers et la recherche publique, mais aussi en théorie pour les paysans, est de sélectionner des nouvelles variétés végétales résistantes à différentes maladies ou parasites.

The 2017 season had very challenging Grape Powdery Mildew conditions at many vineyards on the Central Coast.

UCANR_EDU 12/11/17 Resistance to the QoI (Strobilurin) Fungicides in Grape Powdery Mildew on the Central Coast

Crop losses of 80% or greater were observed at some of the most heavily impacted sites. The wet and overcast conditions in the spring were a primary factor leading to the heavy powdery mildew pressure. However, observed infection conditions were not necessarily uniform within regions; some vineyards suffered heavy infections while other nearby vineyards of the same variety had minimal problems which suggests that some control programs were much less effective than others.

A constant concern is that powdery mildew can develop resistance to certain classes of fungicides that have a higher risk of such resistance occurring. The development of resistance in powdery mildew to fungicides has occurred with previous chemistries.

VITISPHERE 19/05/17 L’Occitanie signe des deux mains pour les cépages résistants (mildiou et oïdium) Ce 18 mai, l’Interprofession des Vins du Sud-Ouest (IVSO) et le Conseil Interprofessionnel des Vins du Languedoc (CIVL) ont signé la convention pour le déploiement de cépages résistants avec l'Institut National de la Recherche Agronomique (INRA) et l'Institut Français de la Vigne et du Vin (IFV).

Mission est ainsi donnée à ces interprofessions occitanes d’accompagner le programme de déploiement expérimental des cépages résistants au mildiou et à l’oïdium. Avec ce partenariat, les deux interprofessions prennent « un engagement collectif pour assurer un déploiement, et un suivi, dans les conditions permettant de garantir la durabilité des résistances portées par les variétés INRA » explique Paul Fabre, le directeur de l’IVSO.

T. acc. Baihe-35-1. The full-length complementary deoxyribonucleic acid (cDNA) sequence of the gene was 1583 bp including 159 bp 5’ untranslated region (UTR), 365 bp 3’ UTR and a 1083 bp ORF which encodes a polypeptide of 360 amino acids with a molecular weight of 38.662 kDa. The deduced amino acid sequence shares an overall 46 to 69.8% sequence similarity with bZIP from other plants. Therefore, we designated this gene as V. pseudoreticulata bZIP (VpbZIP-like).

Abstract : Grapevine requires numerous harmful plant-health treatments, in particular to control downy and powdery mildews, caused by Plasmopara viticola and Erysiphe necator, respectively.

One way to reduce the use of fungicides in viticulture is to create resistant grapevine cultivars. European cultivated grapevine (Vitis vinifera, 2n=38) is susceptible to mildews, whereas related species such as Muscadinia rotundifolia (2n=40) exhibit high levels of resistance. In breeding programs, resistance factors from these related species are introduced into the susceptible elite varieties.

NAFU1 was maintenance on detached grapevine leaves by contact with infected leaves. A quick method to evaluate PM resistance on grapevine was established using NAFU1. Wild Chinese Vitis resistance to NAFU1 was assessed using the established method. Abstract Keywords Abbreviations. J.
