Three international groups inform about
PPP and their management for each type of
pest:
However, even taxonomically distant pests such as weeds, fungi and insects may have common biochemical targets. Therefore, it seems logical to consider insecticides, herbicides and/or fungicides acting on the same target as having the same mode of action. In addition, just like “classical” PPPs, biocontrol products can be confronted with the evolution of resistance in targeted pests, which implies considering them as a mode of action in their own right and integrating them into this nomenclature.
R4P therefore proposes a unified classification of PPPs that takes these particularities into account and groups under the same code substances or biocontrol agents registered against pathogens, insects/mites and/or weeds.
