Details
This work is part of the ACOMPLI project. The ACOMPLI project
is part of the Strategic Action Plan for the anticipation of the potential
European withdrawal of active substances and the development of
alternative crop protection techniques (PARSADA). It is financed by
ecological planning funds. The French Ministry of Agriculture cannot be
