Permanent covers and service plants in Normandy trial

The document details the 2024 trial at Projet XP MSV Normandie, focusing on Sonchus plants as habitat for Macrolophus, a key biological control agent. With no harvest clearance, plant survival remains uncertain. Seed collection and potting from late December 2024 aim to enhance germination in 2025 through spaced sowings, controlled irrigation, and thermal stability. The goal is to expand and redistribute Macrolophus populations in the greenhouse. A risk of Nezara infestation requires close monitoring. Lobularia, a fragile species, will also be renewed. Sunflowers are grown separately in a greenhouse with concrete pathways, wooden supports, and a transparent roof, surrounded by vegetation.
