Subsequently
many operations are performed on the green bud (removal of small clusters
of grapes,of secondary branches and pruning the tips of the shoots) to
achieve both, a high and loose as well as a well-distributed foliar wall.
This increases the quality of the grape and also has a strong protective
function against possible attacks by fungi and other diseases. The vines
are safe-guarded from diseases with organic products and this protection
is limited to preventive measures during adverse weather conditions, motivated
above all, by promoting the natural defensive system of the plants and
local fauna. Small doses of elementary sulphur and copper, natural soap,
garlic extract, Bacillus thuringensis, pheromones, potash silicate, alcohol,
yeasts and fennel oil are all applied. The yield is limited to 1 or 1.5
kilos of grapes per vine according
to variety and year (climatology), to achieve an optimum equilibrium between
foliar mass and fruit. |
