Home gardeners acquired manure from a horse stable. The manure was added to soil in raised beds as part of the home vegetable gardens. Believe forages (hay) that was purchased by riding stable was treated with a herbicide containing the active ingredient aminopyralid. Reporter has been trying to trace back to find the farm that sold the hay. Reporter called/emailed the sales rep for Corteva, [Name], to explain the incident and to try and obtain information on how long this active will remain residual in manure. Milestone Herbicide has been purchased by farmers in this province. The american label is very specific on instructions indicating that the manure and hay should not leave the farm due to the residual nature of the active and the potential to do harm to susceptible plants. The end users of this pesticide are applying to their forage fields to control dock weed. Many farms are selling the baled hay to other farmers including dairy, horse and goats. The end users are not advising those purchasing the hay that it has been treated with a residual herbicide and that the manure should not be composted/mulched and used near susceptible plants. The Canadian Label states: 'Clippings or hay from vegetation which has been treated with aminopyralid should not be used for composting or mulching. Aminopyralid residues pass through animals unchanged and are still herbicidally active. The manure from animals grazing treated areas or fed treated hay should not be used around susceptible plants.' The American Milestone label states: 'Hay from grass treated with Milestone within the preceding 18 months can only be used on the farm or ranch where the product is applied'.
