Plant Doctor and Holohomeopath Radko Tichavsky answers questions about rhynchophorus on Palm trees, yellow rust on garlic and onions, Anthracnose in Chilies, and a houseplant turning yellow. Send your questions to [email protected]

Radko Tichavsky is a Czech born Mexican Agrohomeopath. He is a co-founder and director of Instituto Comenius in Mexico and author of Handbook of Agrohomeopathy, 2007 (Spanish) and Homeopathy for Plants, 2009 (Spanish), Organon de la Holohomeopatía and creator and teacher of Holohomeopathy.

He is now offering a one semester virtual course in Holohomeopathy (in English). You can learn how to define and analyze holons and how to repertorize the specific homeopathic treatment beyond just disease or pest names. You can find out more here:


Organon de la Holohomeopatía

Six years in the making, it is the latest book by Radko Tichavsky, researcher on the application of homeopathy in agriculture. This Spanish language book covers homeopathic interventions in agriculture from the holistic view, allowing greater certainty in repertorizations. It addresses a novel concept of metabolic similarity, not only among plants, but also among different species of the animal and plant kingdom. It studies the formation and dynamics of attractors, areas of greater vitality within the holons and coexistence units of different living organisms.  Holohomeopathy is a fascinating contribution to the application of homeopathy to plants.  It allows one to discover a universe of surprising relations in vital dynamism. It puts into the hands of the agricultural producer a valuable tool for the successful handling of pests and diseases in crops of any size.  For ordering or information: [email protected]


Dear Mr. Tichavsky,

The place is South East of France. It is on the hills of the French riviera. The climate is Mediterranean mild in winter (it might ice in the early morning but then the sun will come and heat the atmosphere. Palm trees are being infected by this rhynchophorus f. that lays its eggs in the trunk and the larvae then eat the trunk and the tree dies.

Thank you

Radko Tichavsky:

Dear Sophie,

The Rhynchoporus ferrugineus is a beetle, parasite of many species of palms of the Arecaceae family, and responds to recent climatic changes, which cause the devitalization of palms.

Numerous investigations have been carried out, for example, to eliminate it by means of entomopathogenic fungi, Metarhizium antisolplae orBeauveria bassiana. However, this type of treatment does not ensure the permanence of healthy palms and only works as a contact insecticide.

Biological control treatments such as bacteria, viruses, fungi, antagonistic insects, entomopathogens have so far been ineffective, because they consider the physical existence of the insect as an enemy to be overcome.

Additionally, attractants such as Eucalyptus globosum essential oil, made from tree leaves and mixed with pine resin or Boswellia sacra resin extract (incense) have been used to lead the beetle into traps. However, the deal in this case is not how to kill the insect itself, but how to re-balance the bacterial community within the plant.

When the gram negative pathogenic bacterium Pseudomonas aeroruginosa is transmitted by Rhynchoporus ferrugineus, this causes the vital descent and death of the palms.The homeopathic treatment is specific for each type of palm, since the homeopathic treatment is done on the basis of metabolic similarity and not directly to the plague, that is to say, the treatment will be different depending on the species of the family Arecaceae,

Homeopathic intervention does not concentrate on the direct elimination of insects (this is carried out by their natural enemies), but rather seeks the establishment of acquired systemic resistance (SAR) in palms and the reduction of the virulence of Pseudomonas aeroruginosa and microorganisms metabolically associated with it.

The remedies used are Ganoderma applanatum, Silicea terra, Acidum salycicum and Acidum ascorbicum in doses between 3-6 CH. Curcuma longa 6 CH is used as the main remedy as it decreases and finally inhibits the virulence of the metabolic complex of Pseudomonas eruginosa in palms.

Dear Mr. Tichavsky,

Here in New Zealand we have a problem with Leaf Blotch on on Barley leaf.  Also, yellow rust on alliums such as garlic and onions.  We are in Leeston, Mid Canterbury New Zealand.

Thank you

Radko Tichavsky:

Dear Carrie,

One of the causes of Rhynchosporium secalis fungus in barley is the susceptibility of the variety, early sowing of sensitive varieties, lack of crop alternation (since the spores of this pathogenic fungus can remain in grass plants and soil for more than 12 months) and is very directly related to the excesses of nitrogen in fertilization (either by early applications of nitrogen of synthetic origin or by the massive application of animal manure).

The homeopathic means used is Silicea terra in different dynamizations (12, 30, or 200 CH), Camellia sinensis 12 CH (elaborated from the essential oil of the tea leaves), Achillea millenfolium 6 CH, and finally Equisetum arvense 12 CH, in case of clayey soil and a bad drainage.

As far as the garlic and onions are concerned, the cause of the rust is a complex of fungi among them Puccinia sp. (P. allii et al.) and Uromyces sp., (Uromyces appendiculatus et al.). Iit is important to maintain a good spacing between plants because maintaining the space between plants of 20 cm drastically decreases the disease.

For homeopathic applications we use Nigella saliva L. (black cummin) in potency 6 CH and Laurus nobilis 6 CH alternated with applications of Sulphur 6 CH with the sap of Opuntia ficus indica as an adjuvant in hot days and oil of Helianthus annus in cool days.

Greetings Mr. Tichavsky,

We have large garden in Sarasota, Florida, U.S. (zipcode 34237) and we planted numerous vegetables. The Bell Peppers were affected by the fungi anthracnose and we lost most of them.  For next year, we’d like to prevent that problem. The weather this year has been warm and damp. We are grateful for any suggestions.

Thank you

Cynthia Davis


Radko Tichavsky:

Dear Cynthia,

Anthracnose in Chilies is caused by a set of fungi Colletotrichum capsici, C. gloeosporioides, C. coccodes, C. acutatum. The appropriate temperature for the development of anthracnose is 20 and 27 °C. Ambient humidity is necessary for infection and fog and dew facilitate the development of disease, spreading pathogenic spores in plants.

It is important to sow bell peppers in well-drained soil, not to water the plants by spraying and to pay good alternation to crops, avoiding repeating the sowing in the same soil for one year.

For homeopathic treatment we use Cuprum metallicum 12 CH combined with Cymbopogon citratus 6 CH (main remedy) elaborated from the mother tincture made in oil.

Hello Mr. Tichavsky,

The leaves of my indoor plant are turning yellow.  Can you suggest a solution to this?

Thank you,

Vidhya Udare


Dear Vidhya,

The plant in the image apparently suffers from a nitrogen deficiency. In this case you can apply a little compost tea accompanied by one application of Silicea terra 100 CH on the leaves. (Compost teas is created by steeping compost in water.)

  • Dear Mr. Tichavsky,
    Our last 2 crops of wheat have been plagued by fusarium, despite conventional preventative pesticide.
    As a homeopath, I would love to apply homeopathy to agriculture.
    1) Do you have any recommendations for fortifying plants against fusarium?
    2) In what areas of cash crop farming have you seen benefit from homeopathy?
    Thank you so much for sharing your wisdom with the community.

    • Dear Brigitte,

      In order to issue a recommendation on the responsible wheat, more information is needed, such as the variety of wheat, the agricultural management of the soil, the type of soil, and the surrounding plants and organisms.
      Fusariosis sometimes occurs, but not always, due to applications of animal excrements (composted or not), other times by low permeable soil and conditions of escessive moisture.
      Among other homeopathic remedies can be used Alumen, Alumina silicata, some mushroom remedies such as Ganoderma lucidum, Ganoderma applanatum, Coriolus versicolor, but as I say each case must be repertorized and often there are great differences from place to place.
      The experience of human homeopathy can help you a little, but agrohomeopathy and holohomeopathy are specialties where among other things you learn to repertorize crops based on metabolical similarity index (it is very different from humans), to prepare homeopathy in large quantities (they are not simple dilutions of granules in large amounts of water as recommended in the books of popular agrohomeopathy), to make some measurements, all this to ensure a good result after the intervention.
      Evaluate the possibility of training in agrohomeopathy, we offer an online course in English for one semester so you can learn, and form skills to perform in agrohomeopathy in a professional manner. You can register in or write to [email protected] to get detailed information.

      best regards Radko
