Évaluation multicritère de systèmes de culture en verger de pommiers dans le cadre du réseau national Expé Ecophyto Pomme

Abstract : Because of new environmental issues in agriculture, the “Ecophyto plan” was implemented in 2008 to reduce the use of phytosanitary products in France for at least 50 %. In this context, the national apple network called “Expé Ecophyto Pomme” was set up in 2012 for 6 years. The objective is to study and propose apple production systems with the aim to limit phytosanitary applications, but also to maintain fruit quality and viability for the fruit farms. For this, multicriteria evaluations are realized with indicators for each of the 24 production systems, located on 6 experimental sites. The difficulty of theses evaluations results from the multisite (national network) and multiannual (several production years) approach but also by the lack of references to measure the indicators. The purpose of this study is to propose evaluation methods for production systems taking into account these elements. A qualitative indicator "the sanitary state of the orchard" is proposed to estimate how pests and diseases have been managed by the production system. Furthermore, according to the technical strategies and methods which have been introduced by the production systems, they were characterized with the Hill and MacRae’s typology of agricultural practices, to give a new way to analyze production system results. Two evaluation methods were studied: a method with no aggregated indicators and an aggregated evaluation method named DEXiFruits. The methodological proposals of this study will constitute the basis of the technical reports and communication of the national apple network “Expé Ecophyto Pomme” for the next years.
