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.
Be sure to read and follow label directions before using any pest control product.
