migliori risultati nelcontenimento della ticchiolatura. Il rame è risultato essere efficace anche
adosaggi molto bassi. Con questi prodotti è possibile intervenire sia a livellopreventivo che
tempestivo. Il rame ed in particolare il polisolfuro di calciopresentano entrambi anche una azione
curativa, che però non è sufficiente acontenere completamente la ticchiolatura. Il rame risulta
essere fitotossico,provocando rugginosità sulle mele, anche a bassi dosaggi. Il grado
difitotossicità del polisolfuro di calcio è nettamente inferiore rispetto al rameed al bicarbonato
di potassio. </span></span><o:p></o:p></span></p> <br /><link rel="File-List" href="file:///C:%5CDOCUME%7E1%5CMARZAN%7E1.MIR%5CIMPOST%7E1%5CTemp%5Cmsohtml1%5C01%5Cclip_filelist.xml"></link><o:smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place"></o:smarttagtype><o:smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="City"></o:smarttagtype><o:smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="country-region"></o:smarttagtype><!–[if gte mso 9]><xml> <w:WordDocument>
