Organic vineyard processes
First of all, at Domaine de la Grange, organic vineyard processes mean a traditional culture of the vine, listeni,g and observing the behaviours of the nature and seasons.
Fertilizers The fertilizers used on the estate are exclusively organic fertilizers.
LABOR - INTER CEP
The plots are^plowed with a frame supporting interceps, i.e. special device working between each vine.
PHYTOSANITARY ISSUES - ANSWER: ALGA MARINE
Phytosanitary treatment of vines: The organic vine standard allows up to six (6) kilos of copper sulphate per hectare. We only use one (1) kilo per hectare, which means 6 times less.
To achieve this result, we work to strengthen the natural defenses of the vine by using seaweed foliar fertilizers that stimulate and strengthen the vine.
PARASITE: OÏDIUM OF THE VINEYARD - ANSWER: SWEET ORANGE
We prefer a treatment based on "sweet orange essential oil" to fight against OÏDIUM, parasite fungus typical in Mediterranean vineyards. These sprays on leaves are associated with wettable sulfur whose slow and sustainable action contributes to the protection of the vine .
OTHER PARASITE: THE EUDÉMIS - ANSWER: SEXUAL CONFUSION
Originally from southern Italy, this parasitic butterfly lays its eggs in the grapes, the larvae consuming the grapes from the inside and producing their excrement. This parasite is now ravaging the entire world.
4 close villages have joined forces to fight against this parasite, in the logic and the Organic approach. These are the villages of Fitou, Leucate, Roquefort, and La Palme.
Since 2017, at the beginning of March, on organic plots of vin growers, pheromone diffusers are positionned.
This pheromone is characteristic of the process of sexual seduction of the female. Each diffuser is placed by hand on the vines to drive males crazy as they do not know where to go for reproduction.
For each hectare, there are 500 diffusers to position under the leaves for a long lasting efficiency.
Diffusers are composed of a small aluminum wire (taken away at the end of the harvesting for recycling) on which the diffuser of the péronome is attached. The heat allows the diffusion and dissipation of the pheromone. The efficiency is spectacular.
