The groundsel myth. It isn't better than ragwort!

This is one of my blog entries where someone has said something on twitter and it requires a longer response than can be posted on twitter.

It started with a very nice tweet.

    Potting up #ragwort for the cinnabar #moths and #solitarybees . I’m going         plant it all along the path in my lawn next spring, I’ll have a 9 metre ragwort         hedge ohh controversial #londonwildlifegarden #pollinators

In the replies was this tweet which contains a number of suspect claims.

Replying to

    maybe try Senecio vulgaris? same family, feeds the cinnabar moth and its             native too. Ragwort is a lovely plant but as you say controversial ( my                     daughter's pony died after ingesting ragwort )
 
Senecio vulgaris is groundsel and  the claim that his his daughter's pony was killed by ragwort is highly questionable. It is actually something that cannot be known scientifically.


Let's start out with this, "Cinnabar moths do well on groundsel" myth. It is a myth and we know the apparent source. Guess what? It is Professor Derek Knottenbelt again.Regular readers will know he is a source of a lot of the nonsense about ragwort.

Groundsel is a much smaller plant than ragwort. It can't support many caterpillars. It is also a more ephemeral plant. The issue about ragwort ISN'T the cinnabar moth it is all the other wildlife it supports. Groundsel is not a good nectar source. Ragwort is one of the best.

Some years ago there was an article in the Daily Post, a Welsh newspaper which said, 
 
        "Prof Derek Knottenbelt, of Liverpool University, believes everyone has a                 responsibility to tackle the “hooligan weed” – and said conservationists may             be wrongly sheltering the plant to protect the cinnabar moth.

        His own studies have shown populations of the rare moth have plummeted as     ragwort spraying has fallen, and suggests the moth feeds better on groundsel."

As I've said the moth isn't the issuebut what studies? It is really annoying when a newspaper assumes because someone is  a professor they are supremely intelligent about everything and always know what they are talking about. He is NOT an expert on insect ecology!

I've already posted a debunk on my website here in my debunk of one of Knottenbelt's awful articles, which was full of errors!.

I will quote the debunk.

A research paper in the journal Entomologia Experimentalis et Applicata [3] studied the effects of three plants on the cinnabar moth. These were ragwort (S. jacobaea) groundsel (S. vulgaris) and coltsfoot (T. farfara) Here are the relevant results:-

Larval batches reared on S. jacobaea had significantly lower mortality (<1%) than those on either S. vulgaris (approx. 4%) or T. farfara (approx. 15%, which was also significantly greater than S. vulgaris)

So the caterpillars do better on ragwort. The paper goes on to talk about the egg laying preference of the adult moths.

Adults showed the same hierarchy of preference as the larvae, however they never oviposited on T. farfara.

This research clearly identifies ragwort as the best and most important foodplant. 

 Now let's deal with  the claim that a pony was killed by ingesting ragwort. First of all, the scientific literature is clear. Animals avoid the living plant unless they are cruelly starved into eating it.  Horses do get poisoned by eating contaminated hay but that is the responsibility of the hay maker and horse owner to deal with . It certainly isn't grounds for telling people not to grow the plant in a garden.

Secondly, it is well established that vets have been diagnosing any case of liver poisoning as ragwort poisoning without properly investigating. The British Horse Society once gave an account of a vet doing just that in their members magazine.

 In any case there is no test which can establish ragwort poisoning reliably. There are toxins that occur in mouldy food which cause exactly the same chemical damage. Their effects are indistinguishable.

Ragwort poisoning is actually rare.  Research by Professor Andy Durham showed that only a small minority of liver problems could fit the ragwort/mould catagory. He is the country's leading expert on this and he believes that we should stop talking about ragwort poisoning. Here is a short audio only video clip of him saying this. It is just 1 minute and 48 seconds long.

Ragwort Control Act - A falsehood enshrined in law.

 The Ragwort Control Act, is one of the most peculiar acts of parliament. It does almost nothing. All it does in essence it is explained in the first line of the Act.

The Minister may make a code of practice for the purpose of providing guidance on how to prevent the spread of ragwort (senecio jacobaea L.).

Anyone who knows how government works in the UK will know this power already existed and didn't need an act of parliament (and also the line is based on a falsehood.)

We got this peculiar law because of a fudge. The ironically misnamed John Greenway MP brought in anti-green private members bill sponsored by the British Horse Society (BHS) and the aim was to force the control of ragwort. The government didn't want to do that but there was so much pressure generated by the campaign that they had to do it. It was therefore fudged and a law that did very little was passed.

The BHS had been campaigning against ragwort with well-proven falsehoods for several years. In fact they admitted it in their 2001 newsletter!

To begin with it was difficult to get the media interested. Their first question was always ' how many horses die of ragwort poisoning every year?' The answer of course was we don't know. We couldn't even come up with an owner whose horse had died of ragwort poisonings- The necessary 'case study' that is so vital for any media story.

They then in effect used made up statistics and did a series of statistically bent surveys to establish that ragwort was a problem. These led to a series of commercial ads repeating their claims to be the subject of action by the Advertising Standards Authority.

 Coming back to the Ragwort Control Act itself, we can then see that falsehood in the line of that Act was the phrase, "the spread of ragwort."

As part of their campaign the BHS et al had been promoting the nonsensical idea that ragwort was spreading for several years and MPs got the idea that it was increasing like a triffid. 

We know about the attitudes of MPs in Parliament because there was an Early Day Motion (EDM) in Parliament. For those not familiar with what an EDM is, it is is a motion, expressed as a single sentence, tabled by Members of Parliament that formally calls for debate, "on an early day". In practice, they are rarely debated in the House and their main purpose is to draw attention to particular subjects of interest.

This was absolutely atrocious. It was factually inaccurate about ragwort poisoning. It was bizarrely wrong about the laws that applied and even the English was bad. You can read my full analysis here Ragwort Early Day Motion.

Just to show the awful start, . It said:.

That this House is concerned that 500 horses died from liver damage due to ragwort poisoning in 2001 and that 1000 deaths are predicted in 2002;

This was complete and total nonsense! There is no evidence at all to support it. Surely someone should have checked that a native wildflower with all the ecological checks on it wouldn't double in a year, which is what this implies.

This is how the falsehood that there was a "spread of ragwort" got applied to the Act. 

And where do you think they got those daft figures from? 

Well we do know who was going around saying it and regular readers of this blog will not be surprised to see that the name of Professor Derek Knottenbelt is associated with this claim. This is the man who claimed that ragwort was responsible for the decline of the cinnabar moth when ragwort is the moth's main natural food!

Was ragwort spreading? Did we need a Code of Practice enshrined in law to stop that spread? Of course it wasn't spreading! Some years later in 2007 there was a government survey of plants and it showed that during the period all this nonsense was being talked, and a falsehood placed in an Act of Parliament, ragwort had significantly declined.

I am unaware of any other law in the UK that was so badly processed as it got a falsehood written directly into the text!

We really need better critical thinking from our law makers.

Ragwort Toolkit British horse Society's shameful behaviour.

The ragwort season's upon us again and with it we have a surge of the usual anti-social behaviour encouraging ecological damage by exaggeration or telling plain untruths about the plant to scare people or force people in other ways to control the plant. It is one of our most ecologically important plants.

We are seeing tweets pointing people to their notorious Ragwort Toolkit. True to form the British Horse Society are telling an untruth about the law. They have form for this. The Advertising Standards Authority took action over their joint leaflet with Warwickshire Council some years ago, but it hasn't stopped them.

Let's get it straight. The Weeds act 1959 allows for orders to be made to control certain weeds. There is no obligation on the government to make orders and unless you are subject to an order there is no requirement to do anything.
It is crystal clear. I cover it on my website.

But the British Horse Society tell this falsehood in their  Ragwort Toolkit.
"Under the Weeds Act 1959, landowners and occupiers are obliged to control ragwort in risk areas."
That is obviously not true!

They tried some years ago to get the law changed with this in a Private Member's Bill in parliament, which originally said:-

 A relevant occupier must take all reasonable steps to remove ragwort from relevant land occupied by him and to prevent the growth or regrowth of ragwort on such land.
Parliament decided against this and this has not become a legal requirement.
The BHS's  tactic seems to be to keep telling people the law says what they wanted it to say, regardless of the truth and they are doing this via their Ragwort Toolkit.

The BHS's and their officers have a long history of putting out dodgy information. One of their specialisms seems to be the rigged survey.  I cover the story they used for one of them where they falsely portrayed that a vet could just turn up to see a horse and just diagnose ragwort poisoning on my website


Then there has been the man who has been their Scottish Chairman, Professor Derek Knottenbelt.  He claimed that it was a problem in South Africa. It isn't!
It took a lot of work, reading papers, and books, but eventually the experts in South Africa were able to tell me that it had never been recorded there!

I've also covered his awful article in a magazine. I document seventeen problems. Including his crazy, mad claim that ragwort is responsible for the decline of the Cinnabar Moth. It is its main natural foodplant!

Now let's get it straight. Being a professor doesn't make him right. Only the evidence does that. Also he isn't a moth scientist. It is blindingly obvious or he would not say such daft things about them.

It is not unknown for people to criticise me just for going against a professor. Well I am really entitled to do this. Nonsense is nonsense never mind who says it. I tend to view such people, on the evidence, as not the brightest and that is being kind about it.

Alastair Stewart, abuse, his fall, and ragwort.

As I keep saying I don't blog too often now, but I have found myself involved in the maelstrom surrounding the ITN Newsreader Alastair Stewart and his resignation. There is an article about me  in the Daily Mail.
The story around is that Alastair Stewart was in effect sacked for a racist tweet where he compared a black person (Martin Shapland) to an ape. This was with a Shakespearean quote.
 
My take on this, my honest opinion, ( and I'll be giving lots of those honest opinions in this particular blog entry) is that it isn't actually the whole truth of the matter at all. I believe that ITN would have looked at his other tweets possibly including those aimed at me and concluded that Alastair Stewart was being unacceptably abusive towards others on Twitter and that he was bullying people.

I should say however, that to a man of obvious African descent like Martin Shapland being compared to an ape like that is a different matter than it would be to me. His experiences and therefore degree of upset will be radically different to mine. I have every sympathy with him.

There is a fake petition on change.org  to get Alastair Stewart reinstated.  I say this is fake, because from the evidence, in my honest opinion, the claims are false. It claims that Alastair Stewart never interacted directly with Martin Shapland, when a credible witness says he did and says it was all about racism which again that witnesses testimony and my experience shows is not likely at all.

The important thing to note is that I actually have copies of a lot of the tweets to or about me that came from Alastair Stewart and I know where they fitted in the conversations that are still available. He has deleted his account so therefore I think it is important that I publish what I have.

First of all, I should clarify that the Daily Mail has it right. I am well known to the staff at Friends of the Earth and I am white. I am Welsh and all my grandparents and great-grandparents were Welsh, I am even one of the 19% of Welsh people that according to the last census can speak the Welsh language.  I am as white as they come.

However,  I don't think it is about race. As I said, I think it is about abuse. I don't think that I am important enough for it to be about me. It is quite likely from what we know about his interaction with Martin Shapland that it  was enough for him to lose his job. I document it below in a twitter thread from another journalist who witnessed it.

However, it is possible that when ITN would have questioned Alastair Stewart that he would have offered up the fact that he had  used the same quote on another occasion against me. Even if he didn't the conversations with me have stuck out to other people. The Daily Mail found them relevant. I also think that any reasonable person would have realised that his behaviour in attacking me was unbecoming to someone of his supposed status. I think it is also quite likely that I am not an important example of this and ITN would have undoubtedly have found other examples of abuse.  In any case, since I have been named in the press as involved I should at least explain what I know.

I realise that I have a number of readers from outside the UK. So I should perhaps explain who Alastair Stewart is. The best way I have to explain is this. If the queen died, Independent Television News ( ITN) who employed him would undoubtedly televise the funeral and prior to his departure his voice would have been the one that I would have expected that we would have heard commenting and explaining what was happening. He is, or was, a very senior TV news presenting journalist.

I am a conservationist and I write and tweet about the issue of a poisonous plant called ragwort. Let's make it absolutely clear, it is poisonous. However, as anyone who studies ecology knows lots and lots of wild plants from oaks to bluebells are poisonous. Ragwort has been subject of a campaign that largely consists of made up falsehoods which make out that it is far far more dangerous than it is. It is also one of the most ecologically important plants and much damage is being done by the misinformation, which I debunk.

The excellent writer Isabella Tree came to the same conclusion in her marvellous, prize winning  book, Wilding when ragwort hysteria nearly sabotaged her wonderful rewilding scheme. I have reviewed her book on this blog.

I can prove my claims. I have the evidence. Much of it is on my website Ragwortfacts.com . Anyone can look at the registration details and they will see that it was first registered 18 years ago. I have worked very, very hard at this for years. I have read hundreds if not thousands of articles and scientific papers. One set of newsletters from an anti-ragwort organisation alone numbers about 150 editions all of which I have scoured for the misinformation they have been producing. I have been and am still scouring the scientific literature to improve my understanding of the issue.

Now let's get on to my interactions with Alastair  Stewart. It started back in 2013 with this tweet.

At this stage it was again all very polite. This is what I expected from a professional journalist of high standing. You can read the open letter here. http://ragwort-hysteria.blogspot.com/2013/08/ragwort-open-letter-to-alastair-stewart_21.html

From the letter you can see I don't have a good opinion of Professor Knottenbelt's claims. I actually went rather easy on the professor. I  knew that he had been making far wilder statements than the ones I used there, but I am a stickler for evidence and chose to use just what we know the professor had written himself rather than press quotes, which might be misrepresentations.

Since then I have obtained some far better material on the professor's claims, in the form of an article that he wrote in a magazine. The magazine put its old contents pages on its website and I just knew I had to have a copy. It would be full of complete and utter nonsense about ragwort!
My debunking is on my website. https://www.ragwortfacts.com/professor-derek-knottenbelt-country-illustrated.html
The professor is undoubtedly a very excellent veterinary surgeon, but if you notice most of the time the things he gets wrong are not veterinary knowledge. They are things about ecology, where he is a layman, and it really shows.

His claims about the cinnabar moth, especially in the book quote which I use on that page, are completely insane! They are utterly bonkers! The cinnabar moth uses the plant as a food. It is absolute lunacy to claim the plant is poisoning it! I have a page giving more technical details.
https://www.ragwortfacts.com/ragwort-cinnabar-moth.html
Unfortunately, as you will see from the page, the story has been repeated and even got into a veterinary magazine!

Incidentally, this is how hard I work at this. I needed this paper from Country Illustrated. I located a copy in a library. I went to get it. I set my alarm clock for 4 am and set off. I got back just before 10PM .  That is 18 hours later.

As I said, things were polite and I had hoped that Alastair Stewart would have had the ability to realise that things were not as black and white about ragwort as he had believed, but alas, this was not the case.

We now move on several years. This is 2018 where Stewart retweeted a tweet from Landrover. You will note this is his customary manner of commenting on a tweet. He retweets it with a comment on top rather than replying. It is of course a form of reply, the author still sees it, but it also means that all his followers see the original tweet. The original tweet includes a picture of a landrover, which I have left out for clarity.

At this point I ought to explain a well-known phenomenon from psychology, which  is called The Dunning Kruger Effect. This term is derived from the work in 1999 of two Cornell University psychologists, David Dunning and Justin Kruger. It is a cognitive bias whereby people who are incompetent at something are unable to recognise their own incompetence. Part of this is that not only do they fail to recognise their incompetence, they’re also likely to feel confident that they actually are competent.
No one is immune from this, which is one of the reasons I am so careful with my evidence, and their research broadly indicates is what is done by more expert people, in that they are cautious. I know  this subject is complicated. My opponents think it is simple.  I would contend, that this effect certainly applies to several of the people in the next set of tweets. They followed directly on from the one above from Alastair Stewart. The Dunning Kruger Effect is the prime piece of evidence that I am quoting when I talk about research and arrogance.

I'll comment between the tweets.

Bill is a debunker. This is a standard answer he has to anyone who posts what he regards as ragwort hysteria or silly things about ragwort. He also debunks poor information about Aneurin Bevan and the NHS, about which he has a really encyclopaedic knowledge and also other things like "Burglar chalk marks". This is the panic that chalk marks in the street are information left about houses by criminals. They are actually done by utility companies!

Have you ever seen a pony die from liver disease due to Ragwort poisoning Mr Ellson?. It may be pretty, it may be critical to the Cinnibar Moth, but it kills, slowly. The only reason Sheep and Cattle do not have symptoms is due to them being slaughtered before they show.
******
Now this is a  classic example of the Dunning Kruger Effect. From my point of view, as someone who has studied the subject long and hard, she is very clearly not competent in the subject, but she is extremely confident that she is correct.
Sheep can be poisoned. It  has little to do with slaughter time, but poisoning them is rather difficult, they have a very high immunity. There is quite a bit in the scientific literature some of which I still have to write up for my website. It is a combination of bacteria degrading the toxins and differences in the enzymes that metabolise them.

Bill is actually correct here. There is really good evidence and we even have the country's leading veterinary expert on ragwort  telling people we shouldn't be talking about ragwort when it comes to liver disease in horses and that it is pretty rare.

Bill is questioning the diagnosis for two reasons. One we know, as we have evidence, that vets  just say liver damage is ragwort when it is established by research that it is only possibly a low percentage. He also knows that there is no definitive test for it, even a biopsy or a post mortem cannot tell the poisoning apart from damage by fungal toxins or other substances. It is covered here, with evidence from world leading veterinary experts. https://www.ragwortfacts.com/ragwort-poisoning-no-test-can-confirm-ragwort-poisoning.html 
The evidence on the page is not the only evidence I have looked at to confirm the facts.

Now this from John Burns irritated me. It is nonsense. It is obvious to me that Alastair Stewart, which is who he is referring and replying to, doesn't have superior knowledge..  We have established that Lisa Rakovic,(@lisarevell) doesn't have it either. It is Dunning Kruger again and especially with regards to critical thinking. Being a respected journalist doesn't make Stewart an expert on anything other than journalism. Thinking that he must be an expert on ragwort just because of him being famous is an example of one of the biggest errors in critical thinking called, "Argument from false authority." Even if the authority isn't entirely false arguing from authority is a risky enterprise. Look at Professor Knottenbelt, a fine vet, but with some insane claims. You don't look for authority to make a case in debate, but you use evidence. If you don't your argument is very weak.

Of course I am talking about the Dunning Kruger Effect here. Their research does indeed tell us that you need the superior knowledge to know if you or someone else has that knowledge.

Am I being arrogant? It is a very robust debate. I am being called a troll, but I have a good response. I have evidence for everything I say.  I am really entitled to be certain , often from first principles of the rules of critical thinking, that my opponents are wrong! You do notice though that she can't answer the question I pose? I am questioning someone who, as I say above, is forming bad conclusions by using a well-known logical fallacy.


Here comes my response, which caused all the trouble. I think this is completely justified given the science. Remember I am talking about research. I would have expected someone of Alastair Stewart's experience to ask me what was the evidence.

Incidentally, there is also more stuff about people with a romantic and inexact grasp of what is true and accurate, regarding people who are more logic orientated as arrogant. There really isn't space to go into it or the time for me either. It is rather complex and this blog entry is going to be long anyway.

Now this is where Alastair Stewart retweets my tweet with the ape quote.



This goes out to all his followers. My honest opinion is that this is an abusive personal attack. He doesn't make any attempt to deal with the issue. Instead he just makes an ad hominem attack to belittle me in front of his many followers. It is just a misuse of his authority.

There was also another tweet like the ape one where he attacked me in the same way by retweeting me to his followers while name calling.

The civil servant who wrote that page does NOT understand the law or is deliberately misstating it. Similar claims in adverts have been stopped by the Advertising Standards Authority and a claim in a magazine has been forced to be retracted after action by Press Complaints Auth.
10:22 AM · Jun 27, 2018·Twitter Web Client

The simple  issue here is that I am criticising a civil servant for getting the law wrong. Ask yourself this, I have a large website on this issue, a blog, and I am consulted for my expertise on this issue by a several large conservation organisations. I have won cases with the Advertising Standards Authority, and the Press Complaints Commission over this issue. I have been thanked by the equivalent Welsh minister when I corrected a similar problem. I believe therefore that it is very reasonable for me to assume, because I have the evidence, that my beliefs on what constitutes the law to be accurate.

 Alastair Stewart implies strongly and, I honestly believe, rather haughtily and dismissively ,that I cannot be right and does this without question and without offering any counter evidence . So who is being arrogant here?

I don't propose digging out the Defra page, which has now changed to be more accurate about the law, but I do know that it confused the law on foreign invasives with the law on native plants considered weeds. It said, as I recall, for instance that you shouldn't plant ragwort. You are legally quite entitled to do so.

What I haven't given in here is all the side threads where Bill Ellson was attacked in the same way  with Alastair Stewart retweeting him calling him stupid and encouraging others who attacked him by retweeting. I have the tweets, but there isn't space or time to include them all.


One of the important things as far as I am concerned as a conservationist,and   which really perturbs me, is a later set of tweets. I do wonder if ITN could possibly have picked up  on this as well, but  I doubt it. It seems that Alastair Stewart may have been encouraging people to break the law protecting our wildlife here in the UK. I don't imagine it would have been intentional, but this is what happens when you don't listen and act dismissively.

 It is illegal in the UK to uproot any wildflower, including ragwort, without permission from the owner or occupier of the land. There are exceptions for certain officials. I cover this here:https://www.ragwortfacts.com/ragwort-uproot.html   ( Incidentally, I had guidance on writing that page from a very, very senior person in a leading conservation organisation. I don't just do things without checking them.)

Someone called Katika Vivuli tweeted that they pull up ragwort everywhere they go, which is, as I said, against the law in the UK. Alastair Stewart retweeted it in his customary manner with a comment and liked the original tweet. You'll also see a response from Bill Ellson in his customary manner. Alastair Stewart had also somehow got the law wrong on  control of the plant, which I am not surprised at.


I have screen grabs here.


And a second picture which shows Alastair Stewart liking the original tweet.


Bill Ellson did tweet that this was illegal. If you look carefully you can see this. It is mostly hidden but it is another of Bill's standard responses so I recognise it.  It is actually still on-line anyway. Katika Vivuli's tweets have since been taken private and are protected from public gaze. Ask yourself, should Alastair Stewart have been more careful?

At this point I want to refer to two twitter threads that I have found. This one is by journalist Kate Maltby You can read about her on her website here

OK, so I'm probably going to regret sticking my oar in. But, Alastair Stewart:

I've admired Alastair Stewart for years, and really enjoyed getting to know him a bit on here.

BUT: I watched the actual exchange in REAL TIME, because I also follow and like his interlocutor. And it was much, much nastier than has been reported. It wasn't just the 'ape' quote.

I was surprised. As I say, I like Alastair and watching this exchange didn't change that, in so much as it made me think this intemperate bullying was totally, TOTALLY out of character. Maybe he'd had a bad day. Maybe he was tired and emotional. There's no way to know.

Most of the tweets have now been deleted, so people now commentating think it's *just* 'the ape thing'. As I recall, AS went on a rant about Martin's education level, dismissed the possibility he could have a degree, really picked on him by quote-tweeting & encouraging a pile-on.

I still wouldn't have sacked AS. Partly because I'm a free speech fundamentalist, partly because we all make mistakes on social media. (I've made lots!)

But we don't know if there were other incidents that ITN took into account. There's lots we don't know.

I'm selfishly sad, because Alastair leaving Twitter means me losing a fun person I enjoyed engaging with here. And the lesson I'm taking from this is that we should all de-escalate and step away from the keyboard more. But please, call off the pile-on onto Martin Shapland.

And on the ‘there’s lots we don’t know’ point, this is now doing the rounds. I do wonder still how on earth ITN let it come to this - in my experience there are constructive ways to guide & warn your staff on social to avoid precisely this type of mess.

And this thread where I have limited things to people who seem to be professional journalists.

The errr irony of Alastair Stewart "stepping down" for social media "errors of judgement" was he spent a lot of time on this website lashing (often young) broadcast journalists about impartiality with awful lecturing quote-tweets.

Comes for us all, I guess.

He was not a fan of me on Saturday Live and used to tweet about it. That was fun. Hey ho.
I  honestly believe that this is a matter of Alastair Stewart having got over confident about himself, as we say, having got to big for his boots. He took on someone else rather in the manner he took on me.  This behaviour escalated and  was unbecoming of someone in his position and led to his resignation.




Ragwort Hysteria latest entries

Horse nutrition bible ragwort nonsense.

As it is the new year I have been doing something which I do every few months.
I scour the internet and various sources and archives for information relating to ragwort.

This is a useful activity to do, as quite frequently new things appear. Often  they are really old things which somehow have been put on-line or archived somewhere or other. This happened last year when I found out about the old article by Professor Derek Knottenbelt. I have just updated my article on it again. This time I number the problem issues in it in my debunking on my website. There are SEVENTEEN of them.

http://www.ragwortfacts.com/professor-derek-knottenbelt-country-illustrated.html

If we had only had this kind of information back in 2004 we could have really stopped a lot of the hysteria, because we would have been able to establish very clearly that the information being circulated was nonsense.

In the process of doing this searching process for this new year. I came across some text from a book. It is called The Horse Nutrition Bible : The Comprehensive Guide to the Feeding of Your Horse and it was published in 2003.

It contains the following text, which I will deal with piece by piece.:-
Of the many plants poisonous to horses, the one they are most likely to consume is ragwort.
Do we really know this? Is it provable? I don't know of anything in the scientific literature that substantiates it.

This and other toxicants, such as heavy metals and some mycotoxins, can cause liver damage.
This is true. Indeed, the damage done by the breakdown products of the compounds in ragwort, that actually produce the toxic effect, cannot be distinguished  from damage done by mycotoxins. They produce the same damage on a molecular level, by cross linking DNA molecules.

Then there is this well-known falsehood.

 In the case of ragwort poisoning, the poisonous principle,
pyrrolizidine alkaloids, accumulates in the
liver and halts its regeneration. 
Oh no it doesn't!  The alkaloids do not accumulate, indeed they are destroyed in the process of cause toxicity, as I say above!  The damage indeed can be cumulative, but there are repair mechanisms and small doses will not cause problems.  We know this from the biochemistry and is an important difference.
If it were to accumulate then every bit would count. With damage accumulating every bit isn't important, because the repair mechanisms prevent damage for small doses. This text in this "Bible" exaggerates the risk.

Incidentally, I blogged recently about people believing that civil servants and government departments were infallible. This error was also made by Scottish civil servants in an official publication some years ago.

And here we go again, another false claim.

Liver disease is becoming increasingly common,
mostly due to the rapid increase in the
amount of ragwort in and around horse
pastures in Britain.
As I point out in the debunking of the Knottenbelt article which I link to above. there was a survey of plants done by the government that covered this period. It showed that ragwort had decreased at this time.

This is yet another example of a horse textbook with poor information on ragwort.

Finally as it is the new year I will once again post the video of the current lead expert in the UK Professor Andy Durham. He has actually done research. Here are some quotes Ragwort poisoning is  "pretty rare really" "I do think we
need to stop talking about it so much." ,  "In reality there really is no evidence it's a common cause of liver disease  in horses."
It is an audio only video of the relevant part of a longer podcast with a small segment added to explain a point which he made at a  meeting that a colleague attended explained with reference to other experts' writing. It lasts just 1 minute 48 seconds in total. Listen to it!

Oh and just in case some ragwort basher tries to say I am taking things out of context, here is the original podcast which lasts 33 minutes.

The video below is shorter but contains the relevant piece.
