This note was elaborated by ACTA, Arvalis, INRA, ITB, Terres Inovia, FNAMS and Agrosolutions with the participation of COLUMA (Végéphyl) for field data. In addition to a brief summary of resistance mechanisms and a description of good weed control practices (those that do not facilitate the evolution of resistance!), it is accompanied by 17 technical […]
This classification proposed by R4P makes it possible to assign a unique code to all active substances sharing the same mode of action, regardless of their use. All details here. Files are also archived online at this address, with the classification of insecticides, acaricides and fungicides : https://osf.io/ubhr5/
