Extension of use and extension of product authorisation for minor use

Extension of use

The authorisation holder may ask for the uses of an authorised plant protection product to be extended, provided that the requirements set for approval are still met. For example, the preparation Källi has been approved for weed control for beetroot and the applicant wants to extend the authorisation to weed control use for fodder beet, carrot, caraway and turnip rape. This is a case of extension of use to multiple intended uses.

Applying for an authorisation for extension of use

  • Fill in the application form
  • Include in the application:
    • draft label text in Finnish and Swedish
    • the GAP table concerning the use and application doses (GAP (Good Agricultural Practices) table on the uses for which the authorisation is asked for in DOC format)
    • research material on biological efficiency and usability
    • research material on residues
    • if necessary, research material on health and environmental effects

Submit the application to Tukes at the address ppp (at) tukes.fi.

Extension of product authorisation for minor use

The authorisation holder, official or scientific bodies involved in agricultural activities, or professional agricultural organisations may ask for the authorisation of a plant protection product already authorised to be extended to minor uses not yet covered by that authorisation.

Tukes may extend the authorisation provided that

  • the cultivated area of ​​the crop is no more than 8,000 ha or the pest itself (target) meets the same minor use definition and

  • the general conditions for approval are satisfied and
  • the extension is in the public interest.

In deviation from ordinary authorisation, Tukes may extend the authorisation without extensive testing to measure biological efficiency and usability. In practice, authorisations of plant protection products for minor use concern crops that are farmed on small land areas (maximum 8000 ha) but are nevertheless of high significance and economic value. 
With caraway (Carum carvi), the definition of a minor use authorisation in terms of cultivated area is only met if the use of the product is applied for only on the year of establishment.


Applying for extension of product authorisation for minor use

    • all data available on residue studies and maximum residue levels (MRL) in particular
    • all documentation available on assessment of risks caused to users, employees and third parties
    • before submitting the application, contact the authorisation holder of the product or his or her representative to obtain any documentation to support the application. Deliver a letter of consent from the authorisation holder with the application.
