Dear Radko Tichavsky,

I have had problem for years with grasshoppers eating all my flowers and leaves causing the death of some fruit trees and bushes. I do not want to spray chemicals. Perhaps you have a suggestion. I would be most grateful.
Karuna Tohow  –  Australian homeopath

Radko Tichavsky:  Dear Karuna, you can apply Thuja occidentalis 100 CH alternated with Sulphur 100 CH. Understood that grasshoppers depend in their  vitality and reproductive vigor directly from the amount of phytoplasmas in plants. That is, the more phytoplasmas (one species of microorganism without a cell wall with characteristic of viruses and bacteria) that are present in the sap of plants, the  more intensely the grasshoppers reproduces.

The grasshopper has important functions in the holon. In fact, they are almost always the symptom of three situations: excess of toxic trace elements, imbalance of C/N equilibrium and presence of phytoplasmas in plants. Besides the grasshoppers can have 6 caecas (issuers enzymes that are similar to human liver functions) and in this regard its role in the holon is to detoxify and chelate toxic substances and accelerate the restoration of balance of nitrogen and carbon in the holon .

Expect from the application of Thuja occidentalis and Sulphur gradual results in decreasing the eggs and larvae in the soil, Concerning the adults, no immediate decrease will be noticed. Then you can apply Tarentula cubensis 12 CH, Pisaurina mira ( “Nursery web spider”) 12 CH, or Latrodectus mactans ( “Black Widow”) 12 CH; in repertorization of remedies it is always preferable to use the remedy made from the spider actually present in the particular holon. In Australia there are a big variety of spider enemies of grasshoppers and you will have no problem in choosing one of them as a source of homeopathic remedy.

It is also recommended to build shelter for spiders such as small bunches of dried grass or rice straw to promote the presence of predatory spiders of grasshoppers and restore equilibrium in the holon.

In case of emergency and only as palliative remedy for the moment, you could use Ricinus communis 6 CH or Lantana camara 6 CH, but always taking into account that the bodies of grasshoppers (although there are farmers who wish to see them dead as well and as quickly as possible) generate proteins which are significantly delaying the decomposition of organic matter in the soil and reduce the vitality of the holon. In this case you have to supplement with additional applications of tea compost and compost.
While my answer may seem much more complex and longer than the question, I would like it to be understood that grasshoppers are not a simple disease or pest to overcome, but are primarily the symptom of the patogenicity of the holon, which indicates certain imbalances to compensate for. Only in this way can we avoid recurrent infestations of grasshoppers in consecutive years.


Thank you for doing such wonderful work! My question is about Cannabis plants with Tobacco Mosaic Virus.  In the past you have recommended Nat. Sal. for strengthening the plant against this virus. Some Cannabis starts we got came down with Tobacco Mosaic Virus.  Should I treat them Nat Sal. , or perhaps with a dilution of Tabacum in water, when watering the plants?

Thank you,


Radko Tichavsky:

Hi Miranda,

The metabolic pathway of cannabis bases its antiviral strategy in two compounds: Tetrahydrocannabinol (non ubiquitous substance only present in Cannabis sp.) and Betabisabolene present in various plants.  Apply Ricinus communis 12 CH which will display more intensely all plant secondary metabolites due to the presence of Shikimic acid, an important metabolic precursor. You can also apply Zingiber 12 CH  and Valeriana 12 CH at intervals of two weeks to strengthen Betabisabolene production in the Cannabis sp.  Remember that there is no such thing as “a universal antiviral remedy.”  Between homeopathic remedies, sometimes Natrium salycicum or Salycilid acid is mentioned as having a magical antiviral remedy on all plants, but the utility of each homeopathic remedy is specific to each plant (for species, it may even be specific for each hybrid) and depends mainly on the metabolic route of each plant, degree of similarity between the remedy and plant, and integration of the plant with the rest of the holon and its members.
Mosaic virus is mainly spread through the contact with infected plants, using vectors such as whitefly or even the humans. Especially you have to be careful with the Solanaceae plants (tomato, peppers, potatoes, eggplant and certainly also the tobacco). It is not a good idea to use any part of Nicotiana tabacum in Cannabis. You have to sterilize cutting tools with alcohol and not allow smokers of tobacco have contact with Cannabis plants. A simple infected leaf fragment, hidden on clothing can quickly become a source of devastating infection. Infected plants must be burned to prevent reinfection.

Dear Radko Tichavsky,

Our first Spinach crop is turning white.  Is there something we can do so the next crop grows healthier?  We are in the Easter United States with moderate temperature and rainfall.

Thank you

Hi Janice. The damage on the image could be a simple nutritional deficiency due to the toxic presence of some trace elements, coupled with the high pH. You can dissolve 5 ml of apple cider vinegar for every 20 L of irrigation water and apply it on the soil routinely to correct the pH.  Also, apply by foliar aspersion Zincum metallicum 6 CH and Magnesia carbonica 6 CH alternated twice a week. Add 10 drops of homeopathy per liter of water and spray it with a little drool of Aloe vera or of Opuntia ficus-indica as an adjuvant.

Dear Plant Doctor

My father is a farmer and he planted a tomato crop in 2 acres. Because of the heavy sun plant grew poorly. We belong to Telangana state Medak district and Atmakur village. There is no rainfall but we have bore in our fields. We can supply 3 hours of water.  Is there a remedy for our tomato crop to help it resist the heavy sun?

Thank you

Nani Hari

Radko Tichavsky:  Hello Nani.  The global warming is stressing plants in practically all countries just now. In fact, this will be one of the main themes of agriculture in the coming years. You can apply plant extracts that help retain water in the soil, for example, sap of Opuntia ficus-indica. Cut into small pieces the cladodes of Opuntia ficus-indica the leave them in water for three days, then  separate the solid part of the plant and you will get a water with slime. Then dissolve it in water 1:20 and apply in irrigation water around your tomatoes’ soil. You can apply the same Opuntia ficus-indica at 6 CH sprayed foliar once a week when the sun goes down.

Dear Plant Doctor,

I want information about how to control the weeds in my Lemon Grass and also Citrus fruit crops using homeopathic remedies. I live in Tenali (Town), Guntur (Dist) , Andhra Pradesh (state ), India. The climate is equal months of heat and cool weather.

Thank you

Sn Lingam

Radko Tichavsky:

Dear Sn. Ligam,

A better way to control weeds is by cutting the plants and leaving them on the surface as mulching. This herb often considered harmful is really a wonderful source of nutrients for your crops. Mulching decreases blows rain on the soil and prevents the soil from becoming compacted. At the same time it helps maintain proper temperature on the soil, holding a high biodiversity of beneficial microorganisms. Observe meticulously the spontaneous plants of your crop. They are often symptomatologies of what happens in the holon and in the soil. They are also a wonderful source of homeopathic remedies for each holon.
