Talk:List of plants poisonous to equines

message: please. I am uncertain at where this should go: Paterson’s Curse (Echium plantagineum) is a plant that is toxic to horses due to a compound contained in the plant known as ‘pyrolizidine alkaloid’.
Ref: http://72.14.235.104/search?q=cache:lfVlYDODVasJ:www.tams.act.gov.au/__data/assets/pdf_file/0011/13250/patersonscursepdf.pdf+%22patersons+curse%22+and+horses&hl=en&ct=clnk&cd=3&gl=au  
Another source of trouble for horses are some fruits especially (I think) quinces.Cgoodwin (talk) 02:26, 25 April 2008 (UTC)
replies: text: Not an expert on the issue but Echium plantagineum seems to belong to class Magnoliopsida, so List of plants poisonous to equines#Class Magnoliopsida would probably be the correct section.  If you are going to use that as a reference, though, the original PDF would be better than the Google cache.  x42bn6 Talk Mess 02:33, 25 April 2008 (UTC)

thread_title: Other poisons

message: This page may fit the wikipedia format for a list of plants (useful for botanists), but the list is relatively useless for the typical horse owner.  Compare with:
(note that they offer the lists sorted by both common or botanical name)
This page would be MUCH more useful for horse owners if the list were presented in a table sorted alphabetically by common name, with multiple entries if the plant has multiple common names.  It would also be much more useful if the list were color coded so that plants that are especially toxic (and should be removed immediately from horse pastures) are highlighted.  It would also be much more useful if the list had a column indicating where the plant is commonly found so that a person in the UK could quickly skim the list to see which plants are commonly found in the UK etc.
Is there some wikipedia reason to prohibit reorganizing this list in the fashion I describe above?  —Preceding unsigned comment added by 71.135.103.134 (talk) 16:26, 19 July 2008 (UTC)
replies: text: Check the page history of this article.  I think once upon a time someone did go through and change all the common names to scientific names.  It probably would start an edit war if they were all changed back.  And I think there is a "sort of" policy on this (having vague recollection of some discussion on the topic) --  I think all the wikipedia plant articles are probably classified under scientific name, but My personal opinion is that I think it would be useful to add the common name IN ADDITION to the scientific classification.  Your ideas are good ones.  What I would do if I were you is look at other lists out there related to plants as well as the guidelines on creating list-type articles in the first place and just proceed from there.  The best thing to do is to create a "sandbox" off of either your own talk page or this talk page and start to create the content the way you think it ought to be, ask people to comment, and generally once you have a community consensus that your sandbox is an improvement on the existing article, you can swap it in.  Of course, keep in mind that this is a BIG job!  But if you are up for it, I'd get yourself a screen name so we can help you more easily, and give it a shot!

replies: text: Oh, and be sure we have chokecherry, black walnut, and red maple on the "very toxic" list for the USA, as well as lupine, locoweed, and leafy spurge as mildly toxic in the western USA.  Oh man, is this a job, but needed!  Montanabw(talk) 06:59, 21 July 2008 (UTC)

text: What you've been doing works well for me.  Good work, by the way.  I threw in a few USA problem plants, if you could be so kind as to "fix" those too...??  Montanabw(talk) 18:32, 4 March 2009 (UTC)

text: How about a table with sortable columns?  Or, make good use of categories, which is the best way to support browsing by common names, without prescribing which common name to sort on.  Most of these plants have more than one common name.  Redirects can be included in categories.  --Una Smith (talk) 20:59, 11 May 2009 (UTC)
replies: text: Suggest in addition to this list creating a category 'plants toxic to horses' and then tagging all the relevent articles (might be more useful to create category of 'plants toxic to mammals' and then make this a subcategory) - I've never created a category so not sure how to go about it - or perhaps there is one already ? Ah ok I see it's already been created discussed and deleted in favour of this list. In which case the various articles in this list seem to be missing links back to this list. 
if I get some time I may go back through the list and see I can point the articles back at this list. EdwardLane (talk) 09:03, 1 June 2011 (UTC)
replies: text: Seems like there might be a category like this already, but talk with Cgoodwin and Dana boomer, as they are the lead editors on this article.  Montanabw(talk) 22:30, 1 June 2011 (UTC)

*Hoary Alyssium
*Big list of problem plants in the USA (bottom of article) and comment on Ragwort in the UK
*List of poisonous wild plants with scientific names (handy)

message: There are serious errors in this list, possibly due to uncritical use of refs.  Many plants are listed which are either not toxic at all, or not toxic in amounts which a horse could possibly eat in real life.  For example, the following plants are are very common in horse pasture and are all regularly eaten by my own horses without trouble: buttercups (Ranunculus), red clover (Trifolium pratense), male fern (Dryopteris filix-mas), ground ivy (Glechoma hederacea), dandelion (Taraxicum).  Then there is perennial ryegrass (Lolium perenne).  This is one of the most common pasture grasses worldwide, and here in the UK you'd be pushed to find a single horse pasture which did not contain it – or indeed in many cases consist entirely of it!  It is like listing potato as a food toxic to humans.  (is it perhaps vandalism...?)  Some of the listed plants may be toxic if a horse gorged on that and nothing else (eg Brassica, ), but that's a very different form of toxicity to other plants on the list, such as yew (Taraxicum) or cowbane (Cicuta) which can be deadly in small amounts.  There are also plants listed which are potentially toxic but which horses normally avoid (eg Senecio, Rhododendron), and others which they can eat safely in small amounts or at certain times of year (eg Prunus, Ligustrum, Pteridium).  Some are listed by genus, when only certain members of the genus are toxic and others are good forage (eg Centaurea).  One of those listed isn't even a plant but a parasitic fungus (Claviceps).  These are all nuances which are not at all apparent in this list, and so could cause a great deal of unnecessary concern in people using it as a source of practical information – which is after all what we're all here for.
My suggestion is that no plant should be included on this list without some explanation of the form and degree of the toxicity – in the way already done for example for Melilotus and Hypochaeris radicata.  Richard New Forest (talk) 12:03, 20 June 2020 (UTC)
replies: text: I agree that it's a very poor list and hence article. If buttercups, red clover or dandelions were toxic to horse, there would be very few if any pastures in the UK that horses could graze! Listing by genus when only a few species are involved is quite wrong. There's also confusion between the plant itself being toxic and it being toxic when infected with a fungus or other non-plant organism. You might as well list wheat and other cereals as toxic to humans because they can be infected with ergot, which is. The list needs drastic trimming, and what is left re-organizing, with a distinction between the plant itself and when infected with something else. Peter coxhead (talk) 08:05, 21 June 2020 (UTC)
