Pest, disease or weed control involves PPPs, of natural or synthetic origin. Independent classifications of PPPs have been proposed according to their category but they do not take into account the fact that highly different organisms may share common biochemical targets that can be inhibited by substances with the same modes of action.
Furthermore, biocontrol solutions are often partially represented in these classifications, whereas many are registered in France and their use will gradually increase in the coming years. Some of them may face the adaptation of targeted pests, which justifies their inclusion in the nomenclature of PPPs.
The unified classification of PPPs presented in this document takes these characteristics into account and assigns one single code to the modes of action registered against pathogens, pests (insects and mites) and / or weeds.
