Nettle
In addition to the way it stimulates the vine’s natural defenses, when used in an infusion, nettle is a growth activator and insect repellent. It promotes photosynthesis, acts as a powerful fertilizer and anti-fungal treatment to protect against powdery mildew and blight. It also promotes strong root development.
We combine it with every sulfur or copper treatment used on our plots.
Lavender
Lavender is used for its insecticidal properties.
Comfrey
Comfrey leaves are used in an infusion. It is a natural insecticide and is a stimulant that is very rich in nitrogen, iron, potassium, silica and rare trace elements like zinc, manganese, and boron.
Its name comes from the Latin word consolida, meaning “consolidating”. It is used as an anti-stress and healing agent after hail or extreme weather events before flowering. It also helps fight powdery mildew, allowing us to limit how much sulfur we need to use. Applied before leaf fall and after harvest, it encourages the plant to lay down reserves for better budding the following year.
Oak
The majestic oak is the king of the forest and can live up to a thousand years in Europe. This incomparable longevity and its great vegetative powers and extraordinary vigor produce a vegetal calcium in its leaves and bark that is very good for helping the vines resist fungal infection.

Tansy
When used in an extraction or an infusion, the flowering parts of the tansy plant make it an excellent insect repellent. It is a perennial, and as such, forms vigorous new shoots each year. These can measure up to 1.5m, with multiple stems, abundant flowers, and a strong scent that is hated by many insects but not by all, such as the aphid-devouring ladybird. We grow it on our grassland where it tends to be invasive.

The valerian-based biodynamic preparation 507 helps extract phosphorus in the soil and forms a kind of protective coat around the compost – essential to any organism.
Absinthe
A natural insect repellent and insecticide to protect against aphids. It is particularly effective against butterflies and leafhoppers aphids when used in a liquid form.
