Nanoparticelle biomimetiche di idrossiapatite drogate con ioni metallici (Cu, Fe, Mg, Zn, K) sono state utilizzate in formulazioni contenenti basse concentrazioni di rame (Cu) e zolfo (S) per controllare la peronospora (plasmopara viticola) e l'oidio (erysiphe necator) della vite. I formulati sono stati testati in campo sulla varietà di vino "Dolcetto" coltivata secondo tecniche di agricoltura biologica, e la loro efficacia è stata confrontata con prodotti commerciali contenenti miscela bordolese e zolfo.
I dati indicano che le formulazioni contenenti bassi dosaggi di rame e zolfo possono essere trasportati in modo efficiente dalle nanoparticelle di idrossiapatite biomimetica e possono ridurre la presenza di micota sulle foglie della vite. Nessun residuo di rame e zolfo è stato rilevato in campioni di vino ottenuti da viti in cui è stata utilizzata l'idrossiapatite biomimetica. Il drogaggio di nanoparticelle di idrossiapatite biomimetica con metalli di transizione è un modo efficiente per fornire micro e macro-elementi alle piante a basso livello di dosaggio. Le formulazioni contenenti idrossiapatite funzionano anche come supporti a lento rilascio di macronutrienti come elementi di calcio e fosforo.
Abstract
Biomimetic hydroxyapatite nanoparticles doped with metal ions (Cu, Fe, Mg, Zn, K) were used in formulations containing low concentrations of copper (Cu) and sulphur (S) to control downy mildew (plasmopara viticola) and powdery mildew (erysiphe necator) of grapevines. The formulations were tested in the field on the 'Dolcetto' wine variety cultivated according to organic farming techniques, and their effectiveness was compared to commercial products containing Bordeaux mixture and sulphur.
Data indicate that formulations containing low dosages of copper and sulphur can be efficiently transported by biomimetic hydroxyapatite nanoparticles and can reduce the presence of mycota on vine leaves. No copper and sulphur residues were detected in wine samples obtained from vines in which biomimetic hydroxyapatite was used. Doping biomimetic hydroxyapatite nanoparticles with transition metals is an efficient way to deliver micro- and macro-nutrients to plants at low dosage levels. Formulations containing hydroxyapatite also function as slow-release carriers of macronutrients such as calcium and phosphorous elements.
