Agrohomeopathy Course!

Radko Tichavsky 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!

  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]

Dear Mr. Tichavsky

I have an Adenium obesum plant for about a year. In the summer months I brought the plant outdoors on the balcony between EST and Dendrobium Brassocattleya. It prospered well with the morning sun growing healthy leaves of a beautiful dark green color. In September, when night temperatures in Rome declined by 4 degrees, and after my “irrational” administration of Lentinula eidodes 6DH and Azadirachta indica 1DH, the leaves, developed brown dry ends surrounded by a black halo and they fell off. I brought it back inside and every three days alternated, Arsenicum album 6CH and Carbo Vegetabilis 6CH with nebulization, but the plant does not give real signs of vegetative growth.

Now I’m thinking of Rauwolfia serpentine, as a remedy possible with secondary metabolites in common (?) And I’m also considering the Oleander. Thank you so much!

Radko Tichavsky:

Dear Roberto,

Adenium obesum is a tropical plant sensitive to low temperatures. Under 10 degrees Celsius it loses the leaves. The homeopathic applications that you made had nothing to do with the fall of the leaves, as this was produced by low temperature. You can make a light fertilization with tea compost. Apply Silicea terra 6 CH only once and wait for a new regrowth of the leaves, with the plant located inside the house.

Dear Mr. Tichavsky,

Can you please suggest a remedy for bacterial wilt in my tomato plants?

Thank you

Radko Tichavsky:

Dear Abdul Salih,

The gram-negative bacterium Erwinia tracheiphila is the cause of bacterial wilt in tomatoes. The disease is transmitted by insect suckers and cutters (for example by Aphids and Diabrotica sp.). In this case it is necessary to control the insects in the plantation with applications of Ricinus communis 6 CH and Larrea tridentata 6 CH alternated for a week, and applied as a spray with Opuntia ficus indica sap as an adjuvant. Preventively, apply Acidum salycicum 12 CH, homeopathic remedy that increases the defensive response of tomato plants.

Dear Radko Tichavsky,

My roses turn brown inside and out.  New growth may appear, but soon it shrivels and dies. I live in Kerala India.

Thank you

The damage that appears in the image seems to correspond to canker of roses, a fungic affection caused by Coniothyrium fuckellii. First of all we must ensure a well drained soil for the plant that does not allow water to accumulate in the root system. For example, you can add sand from the river to the soil to increase the correct drainage. You can apply Allium sativum 4 CH alternated with Vanilla planifolia 6 CH (elaborated from the fruits) with olive oil as an adjuvant. All pruning must be done with strict disinfection of the cutting tools with alcohol and subsequent application of Ledum palustre 6 CH.

Dear Mr. Tichavsky,

We’ve had problems with Apple Scab disease, which we learned is a fungal disease (Venturia inaequalis ).  We live in Edison, New Jersey (U.S) where we’ve gotten a lot of rain this season. Zip code is 08906.  The weather is generally moderate.  Can you make any suggestions?

Thank you

John McGee

Radko Tichavsky:

Dear John,

The Apple scab is a complex of ascomycetes fungi, including Venturia inaequalis and Spilocaea pomi. There are two critical periods of the disease: during flowering and after the leaves fall, and the condition becomes more intense during unusually long rains. During flowering you can apply Thymus vulgaris at the potency 6 CH, applied as a spray with olive oil as an adjuvant. In the spring before flowering apply Ganoderma lucidum 6 CH with a little olive oil as an adjuvant, and after the fall of leaves, Origanum vulgaris at 12 CH with olive oil as coadyuvant.
