| 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. |

| 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. |

| 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... |

| Ascospores produced on scabbed leaves in the leaf litter are the main source of scab primary inoculum, causing scab infections in apple orchards. The purpose of this experiment, carried out during two years in a commercial organic orchard, was to assess the combined effect of removing leaves from the alleys and ploughing in leaves within the row on scab primary inoculum and therefore on scab epidemics. Scab lesions were monitored on leaves and fruits by assessing scab incidence and scab severity. In 2003, scab severity was monitored at different distances from the unremoved leaf area, in order to estimate ascospore spreading. At fruit harvest, during two years with low (2003) and high (2004) levels of scab development, the leaf litter ploughing in /... |

| 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... |

| 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... |

| 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... |
