I don’t know if ALS’ers are aware of the problems associated with contamination of manure and mulch from pasture treated with the broadleaf herbicides containing aminopyralid…there have been lots of cases in the UK, and apparently, also cases here in Australia, so it pays to be very careful where you source your mulch and manure.
Aminopyralid is a broadleaf herbicide used to control weeds in pasture, it has no effect on grasses but lingers so hay or straw cut from the pasture or manure from animals that graze on it can have disastrous consequences for your veges(or any part of your garden for that matter)and it can render the garden unusable for as much as two years. :jawdrop:
I know the farmers in my area use Grazon which contains this pyridine…Hotshot is another but there are others….of course there is no way to know if the mulch you buy has been contaminated unless you know the source well!
Lots of info if you Google it!January 15, 2013 at 10:42 am #530517
the shole system is being corrupted through greed of a few.
are you also aware that sorghum growers spray their crop when science tells them their grains are mture enough for market, they spray them with weed killer commonly glypho, so would images all grain growers including corn might also and maybe even neavy beans, baked beans resource.
many of us use grains to feed our chooks and milking goats or cows.
much grains used to feed starving populations. we garden without manure or bought in mulches as much as we can we do buy in spoilt hay and sugar cane mulch along with mushroom compost which now teh farming of use masses of chlorine in producion so even if teh farm uses town water already with chlorine and fluoride, they add more chlorine.
sad place this current world

Thanks for that Lostinthefog. :tup:
Yes it has been brought up on als before but then so has heaps of stuff and it’s often good to raise it again for newbies and to remind the long term alsers. :tup:January 15, 2013 at 11:59 pm #530519
I raised this very concern, Spring of last year, with the school horticulturalist … BEFORE the evidence was in … that the mulch he was planning on spreading might be contaminated.
And it happened (fortunately across only a few small square metres), that a bale of hay was, indeed, contaminated with systemic herbicides. The next crop withered and died … where, right next to it, in exactly the same form of soil, the crop thrived and produced.
Yes … caution in all things manure and hay. How very sad, eh?January 16, 2013 at 9:52 am #530520
I wonder if this may be the problem for a lot of home gardeners (like myself) who are doing the “right thing” & mulching heavily with whatever we can buy, only to find our entire garden either dies off outright or just totally fails to thrive.
Alright, the hot days we’ve had & trying to watch the water consumption isn’t helping either, but this year I’ve mulched the garden more than I have in the last couple, & nothing is doing really well (except for the rhubarb & a habenero bush). I’ve also seen other people from my area on another forum who are saying they are having problems, & from what I’ve read of them previously, they are also mulching heavily.
It may not be “the” reason, but it may be “a” reason.January 16, 2013 at 10:40 am #530521
I have posted about this before ……… we have had most of our property contaminated by using horse manure from the local riding school ……… the farmer who supplied their hay used aminopyralid and it went through the horses ……….. we only found out after using manure on a crop of jerusalem artichokes that grew deformed then read an article by Monbiot in the uk Guardian ……….
have to wonder what harm this also does to the animals that eat it ……. we had to slash all our paddocks that year but there is no way to know if it is still there and if we are now consuming it in the goats milk …….
it is certain that most conventionally grown grain etc will be contaminated plus meat and poultry
but no one wants to knowJanuary 16, 2013 at 11:10 am #530522
we have been told about piles of stall sweepings from race horses at the race track, as much as we could use more organic materila free by the trailer laod, i was hedging a bit but reckon i’ll give it a wide birth teh racing industry noted for using enhancments as well, from the mouth of an owner trainer. like politics hey a lot of tainting.

I first read about it in a RHS magazine, there seems to be little publicity about it in Australia, probably many gardeners have had problems due to this chemical but have written it off as disease or some other problem…it just wouldn’t occur to most that it could be caused by the mulch or fertiliser.
So many gardeners around here buy sacks of sheep manure & there is no way of knowing if the sheep have been grazing on contaminated pasture, my husband works on several of the local properties and at least one uses Grazon…
This is the kind of thing that that twit on Gardening Australia should be publicising….I only found out by accident, many people obviously have no idea. You’re right Ggang-no one wants to know..afraid of upsetting the farmers(who are VERY prickly about chemical use)or the big chemical companies? My husband works as a gardener on the properties…not on the farming side-and he has often been told not to be a sissy when he refuses to use certain sprays without protective gear…they’re all ‘don’t be such a big girl..it’s perfectly safe’!
And lets be honest…some of the farmhands aren’t the brightest bulbs in the pack, and they often mix sprays at the wrong rate, or fail to wash out sprayers between different chemicals, makes your blood run cold…
At the very least commercial outlets that sell mulch and manures should ensure that their products are clear of this particular chemical.January 16, 2013 at 11:41 am #530524
i also think some of our forums should have their finger on the pulse, that is one reason we gather together, over at pri the same.
our food chain is becomming more and more corrupted, i needed some green stuff wo i cut down some weedy shrubs growing among the pines next door, when we get our own chooks that will help a bit.
some tv shows good at plagerising ideas and not much else.

One mulch that the aminopyralid cannot be used on is lucerne (being part of the pea family, it is ruined by both direct spray and soil residues of this chemical.
So, if you can tolerate the expense, lucerne makes an excellent mulch.January 16, 2013 at 3:19 pm #530528
Good to know, ma.
Would that be the same for pea straw then? We’ve used that before only problem with it seemed to be that we had peas growing everywhere and it became a haven for slugs/snails.January 16, 2013 at 3:20 pm #530529
Here’s a list of herbicides that may be used in Lucerne.
Regarding Hot Shot it can cost over $550 for 20 litres, that will cover only about 40 hectares.
Hay growers, well the ones I know and buy hay from, can’t afford to spray pasture grasses with herbicides. There just isn’t enough profit margin in it after fertiliser and fuel costs. I wonder how many pasture grass hay growers regularly use herbicides for broadleaf weeds.
As far as I know Lucerne growers are regular users of herbicides for broadleaf weeds.January 16, 2013 at 3:33 pm #530530
One of the reasons Lucerne growers use herbicides is to control this spiny khaki weed. Bloody awful plant. When an animal gets a mouthful of lucerne with khaki weed the whole contents is spat out.
I always fish around inside some bales for spine before I buy Lucerne.
