For the protection of the environment and the safety of personnel, the use of phytopharmaceuticals is limited to strict necessity and regulated by specific authorizations, in compliance with the FSC® Standards and the Italian legislation. Precise rules also involve application modes and distribution procedures: compliance with the quantities defined for active ingredients, spraying carried out in the absence of wind and in the coolest hours, use of low toxicity products, regular maintenance of equipment, and use of protective clothing. The application of phytopharmaceuticals via aerial spraying is prohibited. Any use of phytopharmaceuticals is registered, and only the use of products specifically approved for poplar groves is allowed.
