In Europe there is no MRL for fumagilline, so it isn't possible to treat the nosema twins at all. May I ask those two questions: - is there a MRL in the USA or Canada (or elsewhere); - I read several times that it is used in Great Britain . Is there someone who knows on which base (since Great Britain, basically has to apply the European rules in this matter)? Kind regards, Ghislain De Roeck, Belgium. ******************************************************* * Search the BEE-L archives at: * * http://listserv.albany.edu:8080/cgi-bin/wa?S1=bee-l * *******************************************************
