  • Is Aminopyralid contaminated manure still a problem?

    I thought that Aminopyralid was no longer legal? I have read, however that it's use is now allowed.
    Clearly any heaps left over might still be contaminated, but is the new stuff likely to be OK?

        I unwittingly picked up a load of contaminated stuff in 2014... always test before use!

          Still widely used on arable (straw) crops if not grassland (comes out in poo). Unless you know the straw used for bedding and the pasture grazed has not been treated you have to assume the worst or do the bean test.

            The hoss muck we get is sawdust based and has weeds growing on it so it seems to be ok. The manure is a problem for some who reckon it is full of weed seeds. As lomg as they are annual weeds, as far as I am concerned it is just green manure!

              I think they still sell clopyralid too which turns up in municipal-type compost. That wiped me out a few seasons back. (Clopyralid was/is used in lawn weed'n'feed).

                  Hi Moreteavicar and welcome to the Vine.
                  To test for amino or clo pyralaid sow a handful of (broad) beans in the muck or compost and see how they grow. Tomatoes are susceptible to it too. In the case of toms they either don't grow or curl up like melted wax and die.
                  It'd be worth sowing a benchmark batch too at the same time in a different medium, just to confirm the seed is viable.

                    Sow a few broadbean seeds in a pot of half manure/half compost. If the manure is contaminated then the beans will grow curly or fern-like leaves.

                      Does aminopyralid affect more/all plants? Would bindweed roots be a good sign that there's no problems with the manure?

                        It affects all broad leaves plants as I understand it. It is used in a broad leaves weed killer commercially.
