For a durable protection of horticultural crops

Our research focuses on the bacterial, fungal and viral diseases affecting fruit and vegetable crops  grown in the Mediterranean Basin. We study the biology and evolution of these microbial pathogens as well as their interactions with host plants, the environment and agricultural practices, to understand better the epidemiological processes and to propose the most suitable control methods with low inputs and no negative impact on the environment or human health.

Guttation phenomenon on a young Gariguette strawberry leaf. In nature, the sap droplets exuded by the hydathodes benefit many insects that hydrate from them. Photo taken as part of the CASDAR project “PRICE”, which aims to study the effect of fertigation as a lever to reduce the risk of powdery mildew and aphids in strawberry crops.
