The last factor present is the
hail. Because of it, it is necessary to use a defence on the
crops, the diversification of vineyards and the mesh or anti-hail
nets in the shape of a roof for the horizontal canopy vines or
vertical on both sides of the trellis vineyard. The meshes in
this case are collapsible to allow the harvest. There is also an
improved fighting technique, originally Russian, of rockets fired
from the ground against the clouds. Nowadays, the technology
also consists of throwing silver iodide on the top of the hail
clouds, but with small rockets, guided by meteorological radar,
launched from aircrafts. They make the hailstones melt before
reaching the ground.

Other no less important issues are
the earthquakes, which often occur on a regular basis, but for
them the wine industry is prepared with anti-seismic measures in
their buildings. The pests and plagues are not a major drawback
thanks to the healthy climate and soils. Despite this, new
vineyards are planted on grafted clonal feet, selected from resistant American vines, franc foot, or grafted on
other European varieties feet.
