</style>Nell’ambito dellafrutticoltura la regolazione della produzione rappresenta uno degli interventipiù importanti per garantire al produttore una produzione costante e di buonaqualità. Nella coltivazione integrata diverse sostanze ormonali sostengonoquesta funzione. In agricoltura biologica le sostanze ormonali di sintesi sonovietate e quindi si è dovuto avviare uno studio specifico relativo all’utilizzodi sostanze permesse dal regolamento CE per l’agricoltura biologica, delletecniche di applicazione di questi prodotti, così come di tecniche didiradamento meccanico tramite un’apposita macchina diradante.<link rel="File-List" href="file:///C:%5CDOCUME%7E1%5CBOTARE%7E1%5CIMPOST%7E1%5CTemp%5Cmsohtml1%5C01%5Cclip_filelist.xml"></link>

<p>Diversi sono stati iprodotti messi a confronto. Tra questi quelli che hanno fornito i risultati piùincoraggianti sono il polisolfuro di calcio, il sapone di potassio e gli oliestivi. Oltre a questi prodotti attualmente vengono sperimentati anche deiprodotti alternativi ad essi come ad es. le borlande ed alcuni sali minerali.Buoni risultati sono stati ottenuti anche tramite l’applicazione della macchinadiradante.</p><link rel="File-List" href="file:///C:%5CDOCUME%7E1%5CBOTARE%7E1%5CIMPOST%7E1%5CTemp%5Cmsohtml1%5C01%5Cclip_filelist.xml"></link><!–[if gte mso 9]><xml>
