Agrohomeopathy Course!

RadkoTichavsky is now offering a one semester virtual course in Agro homeopathy (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:

New Book!Oct Plant

Organon de la Holohomeopatía – Six years in the making, it is the latest book by RadkoTichavsky, 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]


Hello Mr.Tichavsky,

I would like to ask about an oak tree with bracket fungus that oozes (see photo below).It started many years ago and then became dormant, and returned during the summer drought this year, at which point the photo was taken.Now the brackets are larger and more slimy. Iam in Sussex, UK where the climate is temperate and this year the summer was unusually dry for a prolonged period.

Thank you


Radko Tichavsky:

Dear Anna,

Pseudoinonotusdryadeus is a parasitic fungus in Quercus, especially in Quercus robur an iconic tree of England. It is of slow pathogenesis, gradually producing loss of growth and loss of ability to accumulate water in the tree. The well-vitalized trees can compensate for the action of the fungus with additional growths and live for many years, but when they are devitalized, for example from prolonged periods of drought, the prognosis of life is limited to only a few years.

What we see in the image is actually only the fruit of the fungus, preparing to produce spores and infect other neighboring trees. When the fruiting fungus is observed, frequently already much of the tree is invaded.The infection of this fungus is usually caused by lesions in the tree´s bark.

The metabolites of Quercus ruber responsible for fungal combat are: Catechin, Chlorine, Iodine, Selenium and Vanillin. In addition to the susceptibility of Quercus ruber to being infected by Pseudoinonotusdryadeus, it also influences the nutritional deficiency of copper and selenium.

The homeopathic plant simillimum of Quercus ruber is Punicagranatum (from the mother tincture made from seeds, fruit peel, and roots). Its application improves the vitality of the tree in general and increases the possibility of new shoots both of roots and in the cup.

Homeopathic remedies should be applied as follows: Cuprum metallicum and Selenium at 6 CH potency, Punicagranatum which is the constitutional plant remedy (it has 28 common metabolites with Quercus ruber) at 12 CH potency and Vanilla planifolia 12 CH.

All the remedies have to be applied with sap of Opuntia ficus-indica (has 5 common metabolites) as coadyuvant.The sap of this cactacea forms a thin nanofilm that decreases the evaporation of water from the tree in periods of drought and forms a kind of nano-bags in the soil that protect and guard water even from periods of great shortage of water.

Dear Mr. Tichavsky

I am a farmer in India inKarnataka state, the town of Sedam. I want to completely avoid the use of pesticides. Our main crops are Green gram, Black gram, Pigeon pea, Split chickpeas and Sorgum.We use lots of pesticides to control caterpillars. Temperature is extreme during summer, sometimes it reaches 48 degrees celsius. During winter it could reach 8 degrees celsius.  We totally depend on rain water.

Thank you



Dear Shankar,

I celebrate your decision to avoid chemical pesticides. All these substances finally deteriorate the life not only of all living beings of nature, but finally and directly of humans themselves.

The period of transition from chemical agriculture to homeopathic agriculture is estimated between 1 and 3 years, since the vitality of the soil must be reestablished. One must increase the resilience of the crops and their capacity of epigenetic response, eliminate accumulated pollution in the holon and increase the biodiversity organisms in the crops.

Catterpillar attacks are almost always related to nutritional excesses and deficiencies in the soil and plants (mainly excess of Nitrogen from animal manure) and also due to the lack of biodiversity. Abundant biodiversity always provides enough natural enemies to control pests.

Vigna radiata (Green gram) and Vigna mungo (black gram) are plants that base their insecticidal strategy on a single secondary metabolite: Rutine. Due to this you must reinforce its little insecticide capacity, for example with the application of Apiumgraveolens (68 common metabolites with mung and with 19 insecticidal metabolites) elaborated for mother tincture of seeds, and with Ginkgo biloba 6 CH (43 common metabolites with mung). The homeopathic remedies are applied in water with sap of Opuntia ficus-indica as adjuvant, applied by spray.

With Pigeon pea (Cajanuscajan) you can apply Daucus carota 12 CH (based on mother tincture made from the seeds) alternated with Rosmarinus officinalis 12 CH (with 52 common metabolites with C. cajan) Regarding Split chickpeas (Cicer arietinum) plant constitutional remedies relating to insecticidal activities in this crop are Allium sativum var. sativum 6 CH and Apiumgraveolens 6 CH (made from mother tincture from the seeds).

The hazardous insects to Sorghum sp. include Ostriniafurnacalis (European corn borer), Chilovenostus(spotted sugarcane borer), Aphis sacchari (sorghum aphid), Leucania separate (armyworm), Phyllotretanemorum (flea beetle), Helicoverpaarmigera (cotton bollworm) and many others. The insecticide activity in Sorghum sp. is based on glycosides. There are three major groups of toxic glycosides in the plant: cyanogenic glycosides, thioglycosides and saponins.

For treatment of insects in Sorghum you can use Aesculus hippocastanum 12 CH (made from the mother tincture from seeds) Borago officinalis 6 CH (containing Dhurrin) and Ceratoniasilicua 6 CH (made from the mother tincture of the seeds)

In all annual crops it is important to maintain permanent mulching on the soil and not to flip the soil layers, to maintain the porous structure and natural shelters for beneficial insects such as spiders that are predators of many insects and also preserve parasitoid abysses that are important predators of pests. Very important is the alternation of crops: do not plant the same crop in the same area consecutively.

Of great use is the application of Ricinus communis 12 CH (prepared from the seeds) with Opuntia ficus-indica sap as an adjuvant.

In addition, the application of homeopathic soil nosode to the potency 6 CH will help to balance the distribution of macro and micro nutrients in the soil.

Dear Mr.Tichavsky,

Thank you for previously providing detailed instructions for me on how to make the remedy to treat tree borer in my grevillea trees. I proceeded with what I hoped were suitable substitutes to what you had advised.As I was unable to find resin for Casuarina Cunninghamiana (Sheoak), I used this tree’s seed pods instead. I visited many trees of this species, but I was unable to find resin on either new or old injury sites on the trunks of this species.

I’ve partially crushed each seed pod & placed them in a brown glass bottle with enough ‘Pure Polish Vodka’, 40%, to just cover the seed pods. I had tried to obtain ethanol 30% as you had advised, but discovered that ethanol is not legally obtainable in Australia, so I’ve used vodka, hoping that this will also be a suitable substitute. I would greatly appreciate any comments you may offer about these substitutes.

I have now made the remedy as per your instructions & sprayed the trees. How often should the trees be sprayed with this remedy? Also, is it appropriate to apply the remedy to the soil in addition to the tree, or is it sufficient to apply to the tree itself only?

Thank you


Radko Tichavsky:

Dear Rhonda,

I congratulate you for your creativity.Sometimes not all the ingredients are obtained depending on the country and its legislations, and the use of vodka is  perfect. The gum or resin of Casuarina cunninghamianacan be obtained easily hurting a little the tree during the high humidity period. The seeds may be a substitute for now, but you should get Casuarina cunninghamiana resin later. You can apply the spray on the tree and also on the soil.


Hello Mr. Tichavsky,

My Cherry tree forms cherries and then a few weeks, later they turn brown and fall off.  What could be going wrong?

Thank you

Diane Hoey

Radko Tichavsky:

Dear Diane,

You don´t say where are you writing from.It is important to identify each problem correctly.The fall of the cherry fruits in this case could be due to one of the species included under the popular name “fruit flies” among others: Anastrepha spp. Ceratitis spp. Bactrocera spp. These small wasps oviposit the fruit propitiating fungal infections and the larva that feedson the fruit and elaborates small gallerias causing its fall. The remedy in this case is Pimpenellaanisum 6 CH (made from the mother tincture of seeds), applied with water and a little sunflower oil as adjuvant, alternated with Ginkgo biloba (with 63 metabolites in common with cherry) once in two weeks, from the formation of fruits time, until their maturity.

Another way to protect the tree is derived from the custom of females of the three species of mentioned wasps, of marking the oviposited fruits with a hormone so that the fruits once oviposited are not oviposited later by another female. Then you would have to capture one female of these small wasps and prepare a mother tincture and apply at 3 CH potency every two weeks in water with a little  sunflower oil (Helianthus anuus) as an adjuvant. In this way the fruits will be protected against the wasp pests, will not fall down and will reach their happy maturation term.The fruits fallen under the tree must be collected and deposited in a 40 cm hole in the soil, sprinkled with lime and covered with soil, to avoid the perpetuation of the plague in the following years.


Dear Dr. Radko,

I would like to know the homeopathic constitutional remedies of Camellia Japonica. For the moment, due to some brown leaves, I’m giving Arsenicum album and Carbo Vegetabilis, alternating every three days.  If possible, I would like a constitutionalforOncydium (attached).

Thank you also for your videos on Youtube!

Roberto Migliorelli

Radko Tichavsky:

Dear Roberto,

Glycine max is the constitutional plant remedy for Camellia japonica.You can apply it at 12 CH potency and alternate it with Taraxacumofficinale 3 CH made from the root of the plant (it has 10 common metabolites with Camellia japonica)
I appreciate very much your questions about the orchids. They are all very stimulating for me, since this area of agriculture is virtually unknown, not only for the holohomeopathy but it also has many unknown issues for growers in general. As for the constitutional remedy of Oncydium sp., this specific orchid has a huge number of secondary metabolites and biotic relations, some known, others little known and many unknown. I will answer your question in the next column, since a larger study is required to determine the constitutional remedy and it will take me more time.

Finally, I want to wish Merry Christmas and Happy New Year celebrations to all the readers of this column, wishing you all health in 2019 and a year with healthy homeopathic crops, free of pests and diseases, producing clean and revitalizing food for humanity.

  • Dear Mr.Tichavsky,
    Thank you for your reply above to my further enquires about treating my grevillea trees for tree borer. I agree that it is probably preferable to use resin rather than seed pods, so I will try your suggestion to do this in the humid weather. In the meantime, whilst the only remedy I have is derived from the seed pods of Causaurina Cunninghamiana, could you please advise how often I should spray the grevillea trees with this if am not seeing any signs of improvement?
    Thank you.

  • Hi Dr Vanakkam,
    We are doing banana forming… Near by our form our another farm land is there..( 1 Acre) . Its been many years, we are unable use the land for banana forming because of salt content in the soils…. How can we change the land in homeopathy way… Pls advise we are living in tropical weather area in Tamilnadu, india
