When I first read about agrohomeopathy (i.e. the use of potentised preparations for the health of plants and soils) I thought that it must be a hoax. Then I realised that it was entirely serious (a Google search returns ~28 000 hits for ‘agrohomeopathy’) – serious but nevertheless too weird for words. Because it is so utterly unbelievable, I cite (in italics) the key parts of an article on the subject.

What’s better than ORGANIC or BIODYNAMIC farming? AGROHOMEOPATHY! What is Agrohomeopathy? It’s the specialized area of homeopathy used to treat your garden and crops. Agrohomeopathy is the most chemical free, non-toxic method of growing food and other crops that you can get. Agrohomeopathy makes your plants resistant to disease and pests by strengthening them from the inside out. In nature, it is the weakest of organisms that are attacked and destroyed. Agrohomeopathy helps build up the plant’s basic structure and gives it optimum health, thus reducing and sometimes even eliminating it’s susceptibility. And the skeptics can’t blame THESE effects on placebo, can they?!….

Homeopathic treatment for your crops is a win-win situation. It is backed by decades of research and practice. Try it for yourself and see. And if you have problems or need help, there are experts in the field who are eager to help, who want to get your feedback & experience…

If you think this is far-fetched, rest assured that other sources go even further. Look at this statement, for instance:

Agro-Homeopathy not only treats the disease symptoms of the plant and performs preventive actions, but can also treat traumas retained in the biological memory of the plant, which resulted from conditions such as forced hybridization, moving to places outside their natural habitats , or exaggerated fertilization that maximizes production to the extreme.

So, plants have a ‘biological memory’ that is able to retain information of a past trauma! Fascinating, this gets more fantastic by the minute.

And there is plenty of practical advice too; just consider this helpful hint, if you are a keen gardener: the effects and benefits of homeopathic Silicea are so numerous that an entire article has been devoted to them at: Homeopathic Silica – The Gardener’s Friend. Needless to say, Silicea is one remedy no gardener or farmer should be without…

According to this website, homeopathic silica is a miracle cure; it

  1. Aids germination of seeds
  2. Reduces transplant shock
  3. Strengthens weak and spindly plants
  4. Increases vigour and resistance of plants to pests, moulds, and mildew
  5. Aids water retention in plants growing on arid soils
  6. Stimulates flower growth, both in number and size
  7. Assists seed generation and development
  8. Improves fruit-setting when applied after flowering
  9. Stimulates premature flowering and prevents seed formation when applied in overdose to weeds
  10. Changes the ionisation of soil particles so that water-repellent soil readily absorbs moisture … and more!

The sceptics can indeed not blame ‘THESE effects’ on placebo. Nobody needs to do that because they do not exist! I could not find a single piece of reliable evidence to demonstrate that highly diluted homeopathic remedies can cure diseases of plants.

I hope that a few agrohomeopathic readers of these lines will correct me by showing me solid data – but somehow I doubt it.

27 Responses to Agrohomeopathy: one couldn’t make it up!

  • Here’s a link to a wonderful German website that will excite you: it’s Neudorff, the producers of gardening products like fertilizers and herbicides. They also do agrohomeopathy, and their products are everywhere in all gardening centers I’ve recently been to here in the greater Hamburg area, one of the biggest regions of plant nurseries in the world… that are not exactly famous of respecting EU directives about pesticides in groundwater.

  • At least no humans harmed this time

  • This is hilarious! If a mineral were missing from the soil that a plant needed…why would you add a homeopathic version of that mineral instead of the actual mineral?

  • Selectively eliminating weeds with a homeopathic overdose. I love it. Let’s see. This must be a potentiated dilution of something that originally had the opposite effect. Or has that doctrine been left by the wayside?
    I don’t want to look at the original articles lest I realize that they were only satire.

  • Is agrohomeopathy more effective or less effective than talking to the plants (the latter method is advocated by a royal authority on matters of both horticulture and homeopathy)?

  • Notice how every condition it is claimed to benefit is subjective and not measurable. A characteristic feature of pseudoscience.

  • So the plants have a memory – mmm, is that because they contain molecules of water that has a memory?

  • All products making health benefit claims for crops have to be approved in the UK under EU Regulation 1107/2009 (or its predecessors). The active component of the preparation MUST also be approved at the EU level, no matter how benign. The full list can be found here http://ec.europa.eu/sanco_pesticides/public/?event=activesubstance.selection

    Agrohomeopathy is almost certainly completely ilegal. Someone should report them to the Chemicals Regulation Directorate branch of HSE who regulate such things in the UK.

    • The only problem is, is that I think its legal to sell water to put on you plants. And that is exactly what they are doing. save money and get it straight from your local water authority. It’ll have memory of fertilizer that should kill your weeds, and weed killer that should make your desired plants grow nicely.

  • I’ll ask my ficus to discuss this with its therapist next week.

  • All the snide remarks aside – here is an experiment you can carry out at home.

    Buy a sundew plant.
    Buy a homeopahtic remedy called ammonium carb. liquid form.
    Put some drops of tap water on the leaves of the plant…. Nothing will happen.
    Put some drops of the remedy on the leaves…. the leaves will contract at once (reacting to the remedy).

    • what potency do you recommend?

      • “either 6C or 12C”:

        “Why dont you try the Darwin experiment yourself? Saying it is not homeopathy doesnt really answers the question. If you do as per my (or Darwins) instructions you will see that a homeopathic remedy in either 6C or 12C will effect the leaves of the sundew plant.”

        Unfortunately the experiments Darwin conducted on Drosera using dilute solutions of ammonium carbonate found that the effect becoming weaker as the concentration got lower, and vanishing at concentrations that were still far higher than these remedies, and he made no mention of having used homoeopathic remedies. See his book Insectivoruos Plants, which reports the experiments in chapter 7.

  • Well I misread Darwins instructions and used a 6C potency, whereas it should have been only something like 7X. However, the plant reacted to 6C as well.

    • nobody disputes that solutions which contain molecules can have effects on biological systems. homeopathy is disputed because of the use of ultra-molecular remedies and the ‘like cures like’ principle. your experiment does not test either of them.

  • Interesting, the plant reacted to a 6C (which is 1 to 1.000.000.000.000). I have tried with a higher potency (12C) on a different plant (the flytrap) with so-so results. Only when the plant was fresh the leaves reacted. But I am sure you are aware of the many on-going experiments with ultra-dilute potencies – not only on plants.

    I was not aware that my experiment should prove the likes-cures-like principle?, but again I am sure – if you have read the Organon by Hahnemann – you should know what is meant by this principle and how often you see this principle in nature.

    And are you saying you would be ok with homeopathy if only they sticked to low potencies and used a book like Clarkes Presriber as a guide?

    • I would not trust anything Clarke has written: “Clarke was a leading advocate of anti-Semitism and served as chairman of The Britons from its formation in 1919 until his death as an associate of Henry Hamilton Beamish. He wrote several articles on Christianity that have a militant bent. When Beamish became a fugitive and fled England, Clarke became the head of The Britons. In fact, he even formed and joined, with two others, its splinter organization, the Britons Publishing Society” [http://www.wikidoc.org/index.php/John_Henry_Clarke]

  • Do you know the book The Prescriber? What does your comment has to do with that book? It is a therapeutic guide and was meant as an example as such and I could have mentioned Tyler, Raue, Boericke, Jahr, Lillientahl, etc.

    I am much more interested in getting a reply to my question – are you saying homeopathy is ok in low potencies using a therapeutic guidebook as guidance?

  • So to understand you correctly, as long as homeopaths sticks to lower potencies (like in France) you are ok with it?

    • no!
      you still have to show that the treatment you give/promote is effective and safe.
      all I was saying was that remedies which contain something might actually work

    • this article seems to be about the development of a methodology to measure effects; what do you want to say by quoting it?

  • Well, with agrohomeopathy it is so easy – you just have to try it and that’s all. I have tomatoes which are growing outside in rainy and quite cold dutch climate. They still have no brown spots thanks to homeopathy (beginning of september).
    I had full garden with snails. Thanks to Helix tosta, I do not have any of them anymore. The same goes for aphids and ants. I haven’t used a lot of homeopathy in my small garden but every time I use I am surprised. But you need knowledge and it is quite complicated.
