Thiram treated seed not acceptable anymore

News publication date: 30 April 2019

As from January 30, 2020, it is not allowed to sow seed treated with thiram. Therefore, from now it is forbidden to send in treated seed for a DUS examination.

Also for maintenance control and Naktuinbouws’ internal list treated seeds are no longer allowed.

All these types of samples have to be sown (also) after January 2020. Until now Naktuinbouw has not had such strict policy regarding treated seeds, as thiram treatment appeared not to have an influence on storability nor on plant development. EU commission implementing regulation 2018/1500 makes an end to this tolerance.

The exact requirements for samples for DUS examinations can be found on our website (Healt and treatment of seeds).
