The partners of the IPSEELON project gathered in Paris on March 19 for its official launch. 

Led by inov3PT, this PARSADA project brings together more than 10 scientific and technical partners: Arvalis, Terres Inovia, the Technical Institute for Sugar Beets, FNAMS, UNILET, INRAE, Cristal Union, the Nord-Pas-de-Calais Chamber of Agriculture, and GEVES. 

It covers more than thirty plant-pest-pathogen combinations and aims to develop, propose, and promote innovative, effective, and sustainable technical solutions for managing these pests across a range of strategic crops. 

Terres Inovia is participating in this project with planned research on the peach aphid and the ash aphid on rapeseed, the plum aphid on sunflowers, and the green aphid on peas and lentils.

Most rapeseed crops are currently at the E to F1 growth stages. Milder weather could reignite flea beetle activity, as the first flowers are now visible in nearly two-thirds of the fields.
Following an early and nearly widespread arrival of the pest in late February, threats persist in fields with slow growth or in sheltered areas (valleys, wooded edges). 
This year, flea beetle larvae are weakening the crop and reducing its resilience. Weevil pressure frequently exacerbates the situation.
Many fields have already been treated against weevils, but a follow-up treatment may be warranted as long as flowering has not clearly begun. Conversely, on healthy rapeseed that has passed the E-F1 stage, the risk of damage quickly becomes negligible, making insecticide treatment unnecessary.
At this time, treatments must remain strictly targeted at plots with confirmed risk, using solutions based on tau-fluvalinate or etofenprox. Apply under favorable conditions (sufficient humidity, limited wind, avoid hot hours) with a water volume > 200 L/ha and strictly outside foraging periods, in accordance with current regulations.

Six new varieties have been submitted for inclusion in the French Catalogue in 2025.
