2.ZERHO : Des combinaisons de leviers et un outil numérique en horticulture pour approcher le pilotage en zéro pesticide

In the 2.ZERHO project, “zero pesticide” experiments were carried out on 3 horticultural systems: a succession of potted plants in the South-West region, cut-flower roses in the tropical region and cut-flower gerbera in the Mediterranean region. Various combinations of levers (macro-organisms, natural defense stimulators, biocontrol products, misting and aeration, etc.) were tested on the three experimental station sites over the six years of experimentation. In all the systems studied, the introduction and conservation of beneficial insects to regulate pest populations are central to crop protection. The results show a significant reduction in IFT (Indices de Fréquence de Traitement). The use of a co-designed digital tool (Baco) enables the effectiveness of interventions to be assessed.
