OMAFRA’s Vegetable Crop Protection Guide (Publication 838) is the source of pest control information for commercial field vegetable production in Ontario. Easy-to-read tables provide information on pest control products for managing insects, diseases, and other pests of Ontario vegetable crops.  Watch ONvegetables for updates on pesticide registrations.  Updates are also summarized in a supplement published in the years that the Vegetable Crop Protection Guide is not rewritten.  Up-to-date publication and supplement information can be found at http://www.omafra.gov.on.ca/english/crops/vegpubs/vegpubs.htm.

1. Control = The product, when applied in accordance with the label directions, consistently reduces pest numbers or pest damage to a commercially acceptable level. Suppression = The product, when applied in accordance with the label directions, does not consistently reduce pest numbers or pest damage to a commercially acceptable level. Under such situations, the level of performance offered by the product must still have value in a pest management program.
2. What about partial suppression? Health Canada states “For non-conventional products, in addition to claims of control or suppression, when efficacy is demonstrated to be below what is considered to be suppression for that pest, other label wording reflective of the product’s actual performance may be considered, such as “partial suppression”. Some non-conventional pest control products provide lower levels of efficacy compared to conventional products. However, considering that there may be a need for these types of products such as in organic production, the label claims may be supported by the PMRA as long as the value is acceptable for the use.”
