Products not listed on the SF Pesticide Hazard Screening List may qualify as least toxic, but you’ll need to provide documentation demonstrating equivalency between the products used and the cited standard. Do not assume an unlisted product is least toxic. Further evaluation and documentation is necessary for any product that is not listed.First, if the product is so non-toxic that it is not even classified as a pesticide by the EPA, it should be straightforward to demonstrate that is equivalent to a least toxic pesticide.Second, evaluate the San Francisco Pesticide Hazard Screening List to determine if a product with the same active ingredient and concentration of active ingredient is listed. You can generally assume that your product will have the same classification as a listed product with identical active ingredient information.Finally, try screening your product using the criteria outlined in the “San Francisco Pesticide Hazard Screening Protocol,” which can be found by following the link to the San Francisco Reduced-Risk Pesticide List. Provide documentation of the screening results to confirm that the product meets the Tier 3 requirements.
