| Description: |
This issue follows on from the “Carrefour de l'innovation agronomique” dedicated to the results of DEPHY EXPE 2 projects - Systems using pesticides as a last resort: results and lessons from 6 years of experimentation. ; International audience ; An increase in biodiversity, either cultivated or associated to crops, is a way to foster ecosystem services, especially pest regulation. The ALTO project (2018-2023) developed within the Ecophyto national program to reduce pesticide use is a transdisciplinary project aiming at the design of diversified agroecosystems to produce fruit in pesticide-free or very low-input orchards. Three diversified orchards in three sites of Southern France were co-designed according to this objective considering agronomic, ecological, technico-economic and organizational dimensions. The first system investigated resource sharing in an agroforestry system. The second one was redesigned 'step by step' from stone fruit and olive orchards with agroecological infrastructures into a diversified production area. The last one was a young highly diversified circular orchard with a pest suppressive design. Three main questions were shared by one, two or all sites: (1) What is the effect of agroforestry on apple tree architecture and functioning? (2) Can diversity and spatial arrangement limit fruit damage by pests? (3) How does diversification impact work in the orchard? To share the approach with farmers, and because knowledge was missing, scattered or just being built, exchanges among researchers and stakeholders in the food sector were organised as thematic 'Cafés Agro' to share experiences and questions about orchard diversification. Agroforestry negatively affected the vegetative/productive balance of apple trees with fewer flower clusters in the shade, while the total tree volume was similar to the control, leading to the consideration of other spatial and temporal assemblages that achieve the trade-off between the need to maintain production and to provide shade during heat waves to reduce ... |
