How likely is my manure to have aminopyralid residues in it?
34 million tonnes of farmyard manure are produced annually from housed animals. Only 1.8% of this will leave the farm and be used by others. 93% of the farmyard manure generated from farms will have come from grassland that would not have received any herbicide sprays. In fact the amount of farmyard manure that may contain aminopyralid herbicide residues is less than 2.3%. As a proportion of all farmyard manure produced, the amount that leaves a farm of origin and may contain aminopyralid residues is less than 0.02%.
