Cultivating the vines using organic methods means following the community regulations on organic farming, mainly reg. 2092/91.
Chemical synthesis products are not used in defense, but only products of organic origin. To prevent fungal attacks of powdery mildew, sulfur is used and copper is used to prevent downy mildew. At each administration, copper accumulates easily in the soil.
Its presence in the ground creates problems of toxicity for the plants, considerably reduces the biological activity of the soil (therefore the natural contribution of mineral elements to the soil) and is particularly harmful to earthworms (structure improvers). It is also toxic for useful insects (coccinellidae, hymenoptera except bees, crisope). For these reasons, the current legislation limits its use to 6 kg / hectare per year.
In the company, however, there are numerous tests to reduce the quantities of copper well below the limits of the law and therefore we are using BACTERIALS ANTAGONISTS TO THE PERONOSA and we are also testing other alternative products of natural origin based on citrus, which in addition to having a fungal and bacteriostatic action are excellent antioxidants and have an invigorating action on the foliar apparatus.
The defense against harmful insects is done with pyrethrum and bacillus thuringiensis
