    How long before manure from a wormed horse is safe for dung beetles and earthworms?

    I use my horses manure in our vegie garden (after its appropriately aged) and I treasure my earthworms and dung beetles.

    I've been assuming the fresh manure passed after 48 hours is safe to put on the normal manure pile. I contain the horses after worming for 48 hours and I separately store that "toxic" manure away from the "normal" stuff.

    I'd love to know how long I have to keep the manure away from earthworms/dung beetles until its safe for them.

    Certain wormers have been tested to be dung beetle friendly - I believe Strategy-T is one.

    Promectin Plus is also one of them too!

    Any wormers that contain the 'ectin' drug eg. ivermectin, abectin kill the dung beetle. I do not use these drug during sept to march when the beetles are active. I will use them this time of year to rotate from the other wormers.

    So does anyone know how long wormers remain toxic after having passed through a horse?

    What sort of worms as there are all different ones? or in general

    Just after a general idea jonty - I'm guessing they'll mostly be pretty similar when it comes to the "withholding period" for my earthworms ;)

    I love using the horse poo on the veggie garden, but haven't been game to use the "after wormer" batch and I'm not sure what its half life might be.

    Ah, I recall something about 48 hours, I know it is in sheep worms (ie. black scour worms) but horses dont get them, have to rack my brain a bit more. I have just done a reminder training session on these nastys!!!

    I'm assuming the wormer is out of their system in 48 hours, just wondering how long the poo they passed is nasty too though - the active constituents of the wormers must break down eventually, but no idea when. ???

    I have always burnt or bagged the contaminated worm manure ready for the tip....
