Influenza dell’altitudine e di due tecniche agronomichesull’infestazione e i danni indiretti causati da Lobesia botrana(denis et Schiffermüller) (Lepidoptera, tortricidae)

Risultato della ricerca: Other


Two years (2008-2009) field observations were carried out to evaluate the effects of altitude, of kaolin application andof early leaf thinning practice on the infestation level and damages caused by grape moth Lobesia botrana. The differenceof 80 m. a.s.l. significantly influenced the infestation level of grape moth, which was lower, of about 20%, at the higheraltitude. The early leaf thinning practice did not influence the grape moth infestation nor the presence of sour bunch rotand grey mould on grapes. On the other hand, kaolin sprayings significantly reduced the infestation level in both altitudes(from 11 to 22%) as well as the presence of sour bunch rot and fungi. However, the percentage of grapes damaged by sourbunch rot, grey mould and aspergilli was significantly lower than the infested grapes in both years.
