Sustainable agriculture to preserve the environment

Les Vignerons de
la Noelle
are committed to the "fight for sustainable agriculture" with
the objective of preserving the environment. The principle is to define
more precisely the type, date , frequency and quantity of phytosanitary
products to be applied so that maximum efficiency can be obtained using
the least amount of products.
The fight against the grape-worm is a perfect illustration. Butterflies
mate in the vineyard. Once the female butterfly is impregnated, she
lays her eggs which later become larva that destroy the grapes. Up until
the present, the butterflies were killed with a chemical substance in
order to stop them from laying their destructive offspring.
Today, Les Vignerons de la Noelle is using a new technique called "sexual
confusion". The male butterfly is aware of the female because of
the sexual pheromones she produces during the mating season. Containers
placed regularly in the rows of vines diffuse the pheromones over all
the parcel. The effect is to make the female very hard to locate. There
are no fertilisations and therefore no larva. The harvest is preserved
without the use of any toxic products.
