Improving the resilience of lavender plantations through agroecological recycling of residual biomass from distillation processes

RésiLav aims to increase the resilience of lavender plantations to abiotic stresses, such as drought, and biotic stresses, such as the presence of pests (Resselia lavandulae and Hyalesthes obsoletus). Global warming amplifies these stresses: increased periods of heat waves and droughts, and expansion of the geographical range of pests. These stresses are already responsible for lavender decline, leading to early uprooting of plots and therefore high economic losses. The installation of a mulch (from residues of parfume, aromatic and medicinal plants that are still poorly valorised) could make it possible to improve the soil humidity rate and act in a combined manner on the life cycle of harmful insects and on the environmental stresses suffered by lavender plantations.

RésiLav therefore aims to evaluate the effectiveness of soil cover by mulching to

1) limit the emergence of pests and
2) improve the survival of plants in periods of drought; as well as to
3) evaluate the economic and technical feasibility of these practices and
4) disseminate them to producers.
