Corroborants and Basic substances are products of natural origin, allowed in organic agriculture, which aim to improve the resistance of plants against biotic stresses and to protect them against abiotic damages. Such substances enhance and do not replace agrochemicals and – if correctly used – they allow a reduction in the use of synthetic products and the release of residues.
The products in this category have different mechanisms of action, specifically the corroborants create a physical barrier, have a phytostimulant function (they promote a self-defense and enhance the action of some antiparasitic products), modify the pH (making it hostile to the development of the pathogens), besides having an adsorbent and dehydrating function. The basic substances, on the other hand, have fungicidal, insecticide and elicitor functions. The above-mentioned products represent an active way towards an ever-sustainable agriculture both for humans and the environment.
