Summary: | In 1997 a study has been undertaken about a kind of wood decay of Actinidia deliciosa, observed in Piedmont from 1994, similar to those recorded in other Italian regions (Emilia-Romagna, Latium) and in France and considered analogous to esca disease of grapevine. Cultures obtained from infected wood have given quite inconstant results; anyway, the microorganisms most frequently isolated have been Fusarium solani and Phomopsis sp.. Control trials carried out by means of fosetyl Al applied to foliage and foot of infected plants didn't give significant results. Good results have been on the contrary attained carrying out prophylactic measures such as ensuring well balanced supplies of water as well of nitrogen fertilizers and making in course of pruning correct cuts, immediately covered with protective mastic
Nel 1997 e' stato avviato un progetto di studio su un deperimento del legno di actinidia (A. deliciosa), osservato in Piemonte dal 1994, simile a quello segnalato in altre regioni italiane (Emilia-Romagna, Lazio) ed in Francia e considerato affine al mal dell'esca della vite. Gli isolamenti da legno infetto hanno fornito esiti piuttosto incostanti; comunque, i microrganismi riscontrati piu' frequentemente sono risultati Fusarium solani e Phomopsis sp.. Prove di lotta effettuate con l'impiego di fosetil Al somministrato alla chioma ed al piede di piante infette non hanno conseguito risultati significativi. Esiti apprezzabili si sono invece conseguiti adottando misure di profilassi quali la somministrazione di equilibrati apporti idrici ed azotati e l'effettuazione di tagli di potatura corretti, immediatamente ricoperti con mastice protettivo |
