Reply to: Aminopyralid contamination is a growing gardening problem Posted June 4, 2022

Caution! I don’t know where Becky’s local dairy farmer is but in the uk and eu the MRL for ap in milk is 20ppb, i think 30ppb in US. A cow can pass a lot of ap through to manure before the milk will be rejected. This low absorption ratio is why dairy pasture is an approved application. Its rather disturbing, but quite typical of the problem, that Becky’s commercial dairy farmer does not seem to grasp this! I would paticularly avoid dairy manure!
