Analyse d’un système de culture visant à se passer de l’utilisation de produits phytosanitaires en production de Mandevilla et Impatiens de Nouvelle-Guinée en pots, hors-sol, sous serre en verre, dans le cadre du projet DEPHY EXPE HORTIPOT 2

Abstract : As part of the Ecophyto plan, the DEPHY EXPE HORTIPOT 2 project aims to develop innovative cropping systems that make it possible to dispense with phytosanitary products in ornamental pot crops, above ground, while ensuring a good quality of production and a decent income for the producer. The system analysis is chosen for this new version of the HORTIPOT project. The analysis of the first part of the crop cycle for the year 2019 (production of Mandevilla and Impatiens) is conclusive. The IFT is zero, the green IFT is 0.92. 72% of the plants are marketable. The gross margin is around € 21,700 and the direct margin € 10,900. The main issues encountered this year were the aphids on Mandevilla and Botrytis cinerea on Impatiens, causing the biggest production losses by decommissioning affected plants. Biological control against aphids on Mandevilla is complicated to put in place. The prospects are mainly to improve the biological control by conservation (establishment of relay plants), and to study the surroundings of the greenhouse and the flows of insects between the inside and the outside of the greenhouse.
