Always read and follow label directions.  This is not a complete list of registered products.  Resistance to some registered products has been seen in Ontario.  Dip tests before field spraying help to reduce costs by avoiding ineffective sprays.  See http://www.omafra.gov.on.ca/english/crops/facts/pbeetletst.htm for more information.
