MATING DISRUPTION ON GRAPE IN TRENTINO

• in Trentino there are 10.000 hectares of grape

• from 2003, MD is applied on ALL the hectares (9.700 hectares)

• … now a little bit of history of mating disruption application in

Mezzacorona vineyards…

MATING DISRUPTION on GRAPE – YEAR 1991

MEZZACORONA SCA - ESAT - ISTITUTO AGRARIO S. MICHELE A/A

• 1991 from field trials to practical application

• small surface (13,7 ha)

• 55 growers were involved, Mezzacorona Winery, ESAT

technician of the area and Istituto Agrario di S. Michele all’Adige

• without cooperatives involvement, the small size of the farms

would had been an obstacle for the practical application of

mating disruption
