Nelle annate 2002-2003 in un vigneto di “Moscato bianco” ubicato in ambiente fortemente favorevole all’oidio è stata sperimentata la difesa eradicante, iniziata in presenza di una infezione già diffusa, utilizzando alcuni prodotti in commercio (dinocap, penconazolo, trifloxystrobin) e sperimentali (difenoconazolo+dinocap, spiroxamina). Nel primo anno di prova, intervenendo in presenza di un attacco esteso ad oltre il 70% dei grappoli, due trattamenti ravvicinati hanno limitato in modo consistente l’intensità, ma non la diffusione della malattia. Per penconazolo e spiroxamina si è notata anche una attività indiretta nei confronti della botrite, mentre trifloxystrobin ha contenuto in modo altamente significativo la muffa grigia. Nell’anno successivo, intervenendo più precocemente (meno dell’1% di acini colpiti), si è contenuta l’attività del patogeno, limitando i danni che, comunque, hanno finito per interessare almeno il 50% dei grappoli. è così confermato che in presenza di oidio conviene in ogni caso intervenire, ripetendo l’intervento a pochi giorni, ma un’adeguata difesa preventiva è l’unica possibilità per evitare la presenza di questa malattia e di tutti gli effetti diretti e collaterali negativi che ne conseguono sulla produzione.

SUMMARY
ERADICATING CONTROL OF GRAPEVINE POWDERY MILDEW
During 2002 and 2003 the eradicating control has been experimented in a vineyard of "Moscato bianco" very conductive to the powdery mildew. The trial started with widespread infection, using some commercial (dinocap, penconazole, trifloxystrobin) and experimental (difenoconazole+dinocap, spiroxamine) products. In the first year of the trial, with an attack extended to over the 70% of bunches, two closer applications have notably limited the severity but not the diffusion of the disease. For penconazole and spiroxamine an indirect effect was noticed also against grey mold (Botrytis cinerea), while trifloxystrobin controlled the it very significantly. The following year, earlier applications (less than 1% of stricken bunches), mostly contained the activity of powdery mildew, limiting the damages, that however interested at least 50% of the bunches. This confirmed that in presence of powdery mildew it is however necessary to treat, repeating the application after few days, but a suitable preventative protection is the only possibility to avoid the presence of this disease and all the negative direct and collateral effects on the crop.
