What is the review status of the other commonly used lawn-care pesticides?
On September 27, 2000, Health Canada announced the priority re-evaluation of the eight most commonly available lawn pesticides, as part of its Action Plan on Urban Use of Pesticides. 2,4-D was one of these. This re-evaluation uses modern scientific standards to determine their continued acceptability for registration, and whether any changes need to be made to the conditions of registration of these chemicals. Chlorpyrifos Re-evaluation of lawn and turf uses of chlorpyrifos has been completed. All Domestic Class products, with the exception of containerized low-concentration ant baits), and all Commercial Class products with claims for uses in and around residences and other areas where children may be exposed, were phased out in 2001. Diazinon Re-evaluation of dizainon for lawn and turf uses has been completed, and this product has been phased out. Malathion Through voluntary action by the registrant, both indoor and residential broadcast turf uses of malathion have been discontinued.
