The series of negative seasonal weather patterns which occurred during the 2009-2010 crop year made several interventions necessary in order to defend wine grapes. In total 2.7 million treatments were carried out, an average of 12.3 treatments per hectare of area treated.
To carry out these interventions 19.1 million kilograms of plant protection products were used and an average of 26.6 kilograms was distributed per hectare of area treated.
From a comparison between the various crop years in which the survey was conducted on wine grapes (1998-1999, 2004-2005 and 2009-2010) a decrease in the quantity used of active ingredients emerges (-8.6 per cent compared with the 1998-1999 crop year), as well as an increase in area treated.
