A 'basic substance" can be described as "active substances, not predominantly used as plant protection products but which may be of value for plant protection and for which the economic interest of applying for approval may be limited".
Criteria for their approval are laid down and specific provisions are set to ensure that such active substances, as far as they do not have an immediate or delayed harmful effect on human and animal health nor an unacceptable effect on the environment, can be legally used in the EU after having been approved as "basic" under Regulation 1107/2009.
Applications for basic substances must be submitted to the European Commission, and an authorisation is issued for the entire EU for an indefinite period.
Basic substances are again included in the EU Pesticide Database on active substances. A summary of the approved uses and conditions of approval, for a basic substance can be found in the Review Report which is available on the page showing the details of that substance.
