At Cazebonne, we only treat with copper and sulphur, two natural elements found in nature

However, copper is toxic in soils when the quantities used are too high. That is why the Demeter (biodynamic) certification only permits the use of 3 kilos of copper per year (we will remain well below this limit). To achieve an effective treatment, a high-performance sprayer is essential. Here is a photo of the nozzles that spray fine droplets onto the foliage.
