Abstract

L'invention concerne l'utilisation d'un mélange de matières valorisables d'origine au moins essentiellement organique pour la culture et les soins de plantes utiles et décoratives par activation de la rhizosphère et/ou phyllosphère, et par conséquent aussi bien pour stimuler la croissance qu'améliorer la santé des plantes afin de les protéger contre des pathogènes, notamment contre les mycoses, les bactérioses et/ou les viroses, mais aussi contre les parasites s'attaquant aux racines et aux parties des plantes en surface. Ces mélanges contiennent: (a) de la chitine et/ou du chitosane à structure oligomère et/ou polymère en combinaison avec les composés suivants, appliqués de manière simultanée et/ou décalée dans le temps: (b) composés tensioactifs écocompatibles issus de la classe des alkyl(poly)glycosides de type huile dans l'eau (composés APG) et (c) radicaux hydrocarbures lipophiles saturés et/ou oléfiniquement insaturés avec des composés organiques dégradables par voie aérobie et anaérobie, présentant une structure grasse. De préférence, on utilise également (d) un ou plusieurs constituants qui se distinguent par des composés de P et/ou de N présentant des radicaux au moins partiellement lipophiles et qui sont le cas échéant appliqués dans la zone des racines et/ou sur la partie des plantes en surface, avec d'autres substances nutritives macroscopiques et/ou microscopiques servant à la croissance végétale.
