It has been brought to the attention of the IR-4 Project by Bayer CropScience LP that the active ingredient fenamidone (Reason® 500 SC Fungicide, EPA Reg. No. 264-695) will not be renewed by the European Commission in the European Union (EU).
The consequences for this action are as follows:
The EU import tolerance will be set to a default value of 0.01 ppm effective November 14, 2019. Also, EU member states were instructed to withdraw registrations of products containing fenamidone by February 14, 2019.
Reason® 500 SC Fungicide will stop being produced for the US market before December 31, 2019. However, distributors and retailers may continue to sell and distribute existing inventory in the US. Also, growers may continue to use fenamidone on labeled crops that will be used for domestic consumption, exported to non-EU countries or exported to EU countries with a final residue level of less than 0.01 ppm.
This change impacts the following residue studies conducted by IR-4 that were registered on the Reason® 500 SC Fungicide label:
· PR 10120 Basil (downy mildew; field and greenhouse use)
· PR 08895 Snap bean (Pythium pod decay)
· PR 09530 Lima bean (Cottony Leak)
· PR 08524 Carrot (Pythium damping off and forking)
· PR 09800 Ginseng (Phytophthora foliar blight and crown root rot)
· PR 07999 Sunflower (downy mildew)
Please note that at this time Bayer CropScience LP is reviewing options to divest fenamidone in the future.
