Just to draw your attention to a report in the Telegraph yesterday on the death of a 43 year old vigneron Yannick Chenet whose death from leukaemia has been linked to the pesticides he sprayed on his crops including vines.
The report claims that over a quarter of the pesticides that are used in Europe each year are used in France and that a fifth of that amount goes onto vineyards despite the fact that they only account for 5% of France's agricultural land.
I've read that elsewhere although the figures vary. In Jean-Charles Botte's Le Guide des Vins Vivants (2007) he quotes microbiologist Claude Bourguignon who used to work for the French National Institute of Agronomic Research (INRA). Bourguignon claims that vines only represent 2% of farmed land in France but use 30% of the pesticides, resulting in a loss of biodiversity as well as a hazard to the health of those who handle them.
