Alternatives to copper-based treatments for the control of grapevine downy mildew (Plasmopara viticola): 5-year synthesis of trials in France and Italy Organic Eprints
Parveaud, Claude-Eric; Gomez, Christelle; Chovelon, Marc; Lambion, Jérôme; Dagostin, Silvia; Pertot, Ilaria.
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). Research on grapevine was carried out by GRAB (Avignon, France) and FEM-IASMA (San Michele all’Adige, Italy). Trials were carried out under natural conditions in order to test reduced doses of copper and copper-free alternatives. Five-year trials proved that copper is the best fungicide. However, the use of new low copper rate formulations and the association of copper-free alternatives with reduced doses of copper or with reduced number of copper applications (limited to the most susceptible grapevine growth stages)...

Apricot susceptibility to blossom brown rot (Monilinia spp.) and leaf rust (Tranzschelia spp.) under low-input production system Organic Eprints
Parveaud, Claude-Eric; Broquaire, Jean-Michel; Mercier, Vincent; Gomez, Christelle; Brun, Laurent; Clauzel, Guy; Guillermin, Armand; Audergon, Jean-Marc.
Production regularity in organic apricot orchards is highly constrained by blossom brown rot caused by Monilinia spp. infections on flowers. Leaf rust (Tranzschelia spp.) development can induce early defoliation, which is detrimental to tree vigour and yield. Copper-based treatments are partially efficient against both diseases but their negative environmental impact should be considered. The choice of cultivars according to disease susceptibility criterions is a key-step towards low-input production systems. This poster presents the susceptibilities to blossom brown rot and leaf rust of 16 apricot cultivars observed during 5 years in two sites.

Assessment of diseases susceptibility of peach cultivars in experimental plots and on-farm for organic and low-input systems. Baseline of French case studies Organic Eprints
Parveaud, Claude-Eric; Brenner , Johanna; Ondet, Sophie-Joy; Gomez, Christelle; Libourel, Gilles; Warlop, François; Brun, Laurent; Mercier, Vincent; Clauzel, Guy; Audergon, Jean-Marc.
Despite a high turn-over of new peach cultivars, their suitability for organic and low-input systems remains unknown for most of them. Diseases susceptibility is an important criteria to consider since diseases control is a bottleneck to peach production in theses systems. Since 2001, 81 peach cultivars were assessed in 2 experimental sites and 7 on-farm plots.

Assessment of the susceptibility to pests and diseases of 36 apple cultivars in four low-input organic orchards in France Organic Eprints
Parveaud, Claude-Eric; Gomez, Christelle; Libourel, Gilles; Romet, Lionel; Warlop, Francois; Simon, Sylvaine; Brun, Laurent; Pouzoulet, Didier; Delebecq, Alain; Tournant, Ludovic; Oste, Sandrine; Laurens, François.
One of the keystones of the organic orchard is the cultivar choice as one element of pest and disease control. However, few exhaustive data sets concerning the cultivar susceptibility to pests and diseases are available for growers. In order to identify cultivars adapted to organic production methods, the susceptibility to scab, aphids and powdery mildew and the agronomic properties of 36 cultivars were assessed in four French sites under different pedo-climatic conditions. Different levels of susceptibility to scab were observed for 23 scab Vf-resistant and 13 other cultivars. In the North of France where Vf resistance is overcome, the Vf cultivars displayed different levels of scab severity. A high variability in the susceptibility to aphids was observed...

Effect of permanent ground cover on agronomic properties and soil fertility in an organic peach orchard Organic Eprints
Parveaud, Claude-Eric; Gomez, Christelle; Bussi, Claude; Capowiez, Yvan.
In conventional orchards, weeds on the raw are mainly controlled with chemical herbicides because of their efficiency, their low cost and ease of use. The most common method in organic orchard to eliminate weeds on the raw consists of tillage operations. However, some drawbacks of these mechanical methods have been demonstrated: (1) the energetic cost (non-renewable energy) is high, (2) this method is time-consuming, (3) tillage interferes with the development of superficial roots and can hurt the trunk, (4) the physical, chemical and biological properties of the soil can be disturb and (5) erosion and runoff potentially increase. Cover crops are interesting alternatives to manage ground cover but the effect on the agronomic properties and the soil...

Effect of White clover (Trifolium repens cv. Huia) cover crop on agronomic properties and soil biology in an organic peach orchard Organic Eprints
Parveaud, Claude-Eric; Gomez, Christelle; Bussi, Claude; Capowiez, Yvan.
In orchards, cover crops are interesting alternative strategies to tillage or chemical herbicides for managing weeds in the tree row. However, little is known about the effect of cover crops on agronomic properties and soil biology in organic orchards. To fill this gap, the effects of two weed managements, a White clover cover crop (CC) versus classical tillage practice (T) on the tree row, were assessed in an irrigated organic Peach orchard. White clover was sown in 2004, 2006 and 2009 in the tree row and ploughed in 2006 and 2008. Root density, earthworm density, water infiltration rate, nitrogen content and water availability were measured in the soil, in the tree row. In 2009, peach root density observed in the superficial layers was higher in CC...

ÉVALUATION DE LA SENSIBILITÉ AUX BIOAGRESSEURS DE 36 VARIÉTÉS DE POMMIERS DANS UN RÉSEAU DE PARCELLES BIOLOGIQUES À FAIBLES INTRANTS Organic Eprints
Parveaud, Claude-Eric; Gomez, Christelle; Libourel, Gilles; Romet, Lionel; Warlop, Francois; Brun, Laurent; Simon, Sylvaine; Pouzoulet, Didier; Delebecq, Alain; Laurens, François; Oste, Sandrine; Tournant, Ludovic.
Les bioagresseurs sont une des principales limites à la production de pomme dans les systèmes conduits en AB et à faibles niveaux d’intrants. Une des clefs du contrôle des bioagresseurs dans ces vergers est le choix des variétés (Trapman et Jansonius, 2008). La variabilité de l’expression de la sensibilité variétale peut être appréhendée grâce à un réseau multi-site pluri-annuel. Quatre parcelles de pommier biologique conduites de manière semi-extensive ont été plantées en 2002 afin d’identifier des variétés d’intérêts pour les systèmes à faible intrants. 36 variétés ont été suivies afin d’évaluer conjointement leur sensibilité à la tavelure, aux pucerons et à l’oïdium.La thématique de cette étude initiée en 2002 se trouve être au coeur des...

Impact of a cultivar mixture on scab, powdery mildew and rosy aphid in an organic apple orchard Organic Eprints
Parisi, Luciana; Gros, Christophe; Combe, Freddy; Parveaud, Claude-Eric; Gomez, Christelle; Brun, Laurent.
The impact of a cultivar mixture within the rows including the cvs Melrouge (low susceptibility to scab) and Pitchounette (Rvi6 resistant) was assessed during 2008e2009 in an organic apple orchard located in Rhône Valley (Drôme, France), on three important pests and diseases: scab, powdery mildew and rosy apple aphid. In this area, the resistance of Rvi6 gene was effective since the orchard plantation in 2004. The impact of the cultivar mixture was assessed per se, but also associated with sanitation practices to decrease the primary inoculum of scab and mildew, and compared to disease development on pure stands of Melrouge. The cultivar mixture showed a good efficiency to decrease the scab incidence on leaves and fruits; a significant effect on scab...

IS LEAF LITTER REMOVAL MORE EFFICIENT THAN LEAF LITTER SHREDDING TO CONTROL APPLE SCAB? A FIRST ANSWER IN A COMMERCIAL ORGANIC ORCHARD Organic Eprints
Parveaud, Claude-Eric; Gomez, Christelle; Gros, Christophe; Asencio, Pedro; de le Vallee, Damien; Brun, Laurent.
In organic apple orchards, sanitation practices are a keystone of a sustainable scab management. Because the suppression of the inoculum by leaf litter removal could be a promising practice, we carried out an experiment to assess the interest of leaf removal versus leaf shredding on disease development and fruit damages. For one of the two cultivars studied, we showed that leaf litter removal can significantly decrease scab damages on fruit and leaf in comparison to leaf shredding.

In France Fruit production is cultivated on 140 thousand hectares, mainly conducted on intensive training system. Very few elements are available on low input training systems while they have to integrate the Global rule under the frame of Ecophyto 2018. In order to evaluate if another system of cultivation will be possible, a project has been developed to highlight the main factors to be integrated in low input training system. A low input multilocal experimental design has thus been investigated on apricot in two main regions of production: Rhone valley and Roussillon. A set of 9 common cultivars with 20 replications each, planted in a complete single-tree randomization design has been established. As already observed in apple orchard, a larger set of...
