What to do if you have Aminopyralid Contaminated Manure?
It is important to check before using farmyard or stable manure
that it does not contain the agricultural weed killer
Aminopyralid has been used on farms to control weeds in
grasslands. Where treated grass was eaten by livestock their manure
may contain residues of the weed killer.
There may still be some affected manure and, while there are no
concerns for human health, its use can cause poor distorted growth
in many crops including beans, peas, potatoes and tomatoes, which
will reduce harvests.
Therefore, ask the supplier to confirm that the manure does not
contain aminopyralid. Stable owners may not be able to offer this
assurance, so be very cautious about using stable manure.
If you have already used manure and now suspect that it might
have contained aminopyralid…..
If it has been used on empty beds in preparation for planting,
dig or rotavate it thoroughly into the soil and leave it for
several months to allow soil bacteria to break down the
aminopyralid. If it has been spread around plants, remove as much
as you can as plants may be affected by the remaining manure.
It is best to dispose of unused or removed manure by asking:
- Supplier of manure
- A local farmer
- Local Council at household recycling centres
Please check before travelling and in all cases you must explain
that it may contain residues of aminopyralid.
