Pêchers biologiques. Sélection de variétés tolérantes à la cloque adaptées à l'AB

Depuis 1999, un réseau national de parcelles permet d’étudier du matériel français potentiellement intéressant en agriculture biologique, sélectionné pour sa tolérance à la cloque. Des variétés anciennes et des hybrides de l'INRA ont été plantés et conduits en AB ; les principaux bioagresseurs ont été suivis pendant plusieurs saisons

Efficacité et coût de la thermothérapie appliquée au cas de la pêche contre les maladies de conservation

Two-years trials show evident efficacy (usually more than 80%, on most of varieties, and for a 50°C treatment during 2 minutes) of hot water treatments against post-harvest diseases (Monilinia sp. mainly). Growers do hesitate to invest since engines remain expensive, but calculation of the treatment cost shows that the investment is covered after 2 or 3 years, for a medium damage rate

Control strategies for limiting olive fruit fly (Diptera, Bactrocera oleae) populations

Olive fruit fly remains the key pest in organic olive groves. Growers need quick and efficient answers because alternative methods to sprays (such as mass trapping or biological control) have not yet given satis-factory results. Preliminary laboratory trials were car-ried out with several active ingredients in various dosages. Efficacy was then assessed at 24 hour and 48 hour intervals after application. The article presents the encouraging results of the trials

Handbook for designing & managing Agroforestry mixing fruits & vegetables

This 40-pages handbook intends to point out the main decisive aspects to have in mind when creating and designing a diversified agroforestry system : which marketing channels, which competencies, which working capacity and organization... Farmers experiences and feedbacks provide an additional value to this practical guide

SMART PROJECT : Agroforestry systems using fruit trees and vegetables in France

Agroforestry systems mixing fruit trees and annual crops are very well developed and studied in tropical countries, but they have been forgotten or neglected during the last 40 years in France and Europe. Current trends and challenges in agriculture (land access, periurban agricultural forms, inputs reduction through functional biodiversity and crop diversification) lead small farmers in France to combine annual plants and fruits with the aim to increase their field performance on a multifunctional basis. The SMART project identified about 150 projects (mostly all being organic) and further explored 40 of them, to better understand organization and adoption criteria

Codling moth prevention: Preserve antagonists in organic apple and pear orchards (BIOFRUITNET Practice Abstract)

Favourable practices will allow beneficials, such as Mastrus ridens, to better establish in the orchard, and help control codling moths. M. ridens are often found in orchards, but its population could also be increased with releases. Practical recommendations • Reduce plant protection products with negative side effects as much as possible, such as sulphur or insec-ticides, and those with broad spectrum effects like Spinosad and Pyrethrum. • Reduce fertilisation between the rows to decrease grass species and possibly favour dicotyledons. • Reduce mowing or soil tillage to keep a high weed cover – this acts as feed and habitat for beneficials. • Set up flower strips in the alleys and around the orchard to attract insects & spiders. • Maintain or renew surrounding hedges to help beneficials shelter. • Set up bat boxes and/or bird nests (about 10/ha for each type)

Conception participative de systèmes agricoles associant arbres fruitiers et cultures annuelles

Innovation in agriculture is needed to face multiple challenges and reach sustainability. We aim at involving farmers in the design of innovative pilot farms, using agroforestry and agroecology to maximize ecosystemic services and minimize reliance to plant protection products. Projects are designed for long channels or for direct selling, with consequences in term of crop diversity and plot size. They started in 2013 and will be run on a long-term basis

Concevoir et expérimenter des vergers agroforestiers en Agriculture Biologique (VERtiCAL).

The VERtiCAL research project focused from 2013 to 2018 on the spatial and temporal diversification of fruit tree systems as a relevant mean for reducing pesticide use. The project resulted in the design and assessment of two fruit agroforestry systems (AFS), called "TAB" and "Durette", managed in organic farming and with specific technical and economic characteristics. The project allowed co-design experiences and led to the development of a new tool for ex ante assessment of AFS. First results show a 52% reduction of pesticides on the TAB system compared to a conventional reference system while reaching yield objectives, and a very low reliance to pesticides on the Durette system. As for biodiversity, specific richness of birds increased from 12 to 24 species on the Durette system, from 24 to 35 on the TAB system. Spatial planning fulfills the working organization, but does not make it possible to fully control pests yet. Results will be consolidated in the continuing EMPUSA project (2019-2025). Both sites are now important demonstration sites for farmers and agricultural advisors interested in implementing AFS
