Minnesota registration information for metribuzin and other pesticide products is available through the Kelly Registration Systems or the Minnesota Registered Product Search.

The only official product label is the label attached to the container of the pesticide being used.
The MDA collects pesticide sales data to provide long-term trends in pesticide use. Sales data should not be used as an indicator of pesticide use in a given year as product bought one year may be held over and used the following year or may be returned unused to the distributor.
