The Canola Council of Canada is strongly urging growers not to treat their bins with malathion before storing canola.


Agronomist Derwyn Hammond says confusion arises because the chemical is registered for use before cereal storage.


He adds at issue is some of our key canola export markets have very strict tolerances on malathion residues, particularly the very valuable Japanese market.


Hammond notes there's really nothing registered for bin treatment before canola storage.

 

Your best bet is to do a thourogh job of cleaning out the bin before adding this year's harvest.
