Cap Zero Phyto (2021 - 2027)

Adaptation of the concept of agro-ecological immunity to crop protection: Rosaceae and Solanaceae, two case studies

The objective of the project is to propose innovative integrated crop protection strategies based on the combined use of immunity levers able to modulate crop defenses. Five immunity levers will be investigated individually and in combination: genetic resistance, companion plants, biocontrol solutions exhibiting PRI (plant resistance induction) action, UV-C flashes and nitrogen supply. Apple and tomato will be used as model crops, with their main pests and pathogens, before transitioning to other Rosaceae (peach and strawberry) and Solanaceae (pepper).

The GAFL unit is collaborating with other partner teams, in the genetic mapping of loci involved in resistance to Botrytis cinerea, Oidium neolycopersici and Tuta absoluta in tomato, and in the analysing of the molecular mechanisms underlying the response of tomato to PRI or UV-C. The efficiency of PRI or UV-C applications to increase the durability of genetic resistance to late blight, will be assessed through experimental evolution. The effectiveness of the best combinations of immunity levers, identified in tomatoes, will be evaluated in pepper, to assess the genericity of these lever combinations.
