Dear Radko Tichavsky,
I have a maple tree that has been sick for a few years. I’ve tried remedies: Thuja, Silica, Psorinum. They did not help. What can you suggest to help to cure the maple tree? Attaching a picture. The Maple tree leaves have white spots. They are dry and curl to the inside. The color of the leaves changed and it’s lighter than it should be. The tree has been sick for a few years. The tree is Japanese Maple. The tree is in Thornhill, Ontario, Canada. ( A suburb or Toronto)
Temperatures vary every year. This Summer: August: night time: 8 – 14 Celsius, daytime: 19 – 22 Celsius. July was a little warmer, June about the same as August. Humid weather, frequent rainfall. I live in the area where a lot of trees are sick. I can’t grow anything. Trees that belong in the city are being replaced often.
The problem in your Acer palmatum seems to be related to the low vitality of the tree and presence of Verticilium sp. fungus, Thuja and Silica are not indicated in this case, so when we look back to Hahnemann’s principle “simila similibus curantur” the best remedy is not the “antifungic” one. In this case the remedy is precisely another fungus similar to Vertiicilium sp. The fungus is sent by the holon because it detects weakness of the tree and is in charge of invading its vascular system, causing the typical spots of discoloration and a kind of death that seems to descend in the plant until its death.
Inoculum of beneficial Trichoderma sp. should be applied in microdoses. It can prevent these attacks since the Trichoderma occupies the space and defends the plant like its vital territory. Another way (don´t combine them together) is to strengthen the vitality of the tree and the circulation of sap in the vascular system of the tree by applying Ganoderma applanatum 12 CH in foliar form, and in the soil, Ganoderma lucidum is also very useful, depending on which of these two remedies is present in your holon.
Dear Dr Radko Tichavsky
I am a regular reader of Ask the Plant Doctor. I have acquired a fascination for your concept of holon. Love you Sir! I undertook a Chili plantation at Wardha, which is in the state of Maharashtra in Western India. Average annual rainfall here is around 1100 mm. Out of this almost 90 % is during the period of June to September. Temperature from June to September varies from 27 to 35-37. Climate tropical.
We make chili beds in the first week of June and plant them around the middle first to second week of July. Besides other organic means like cow manure etc, I try to depend on agrohomeopathy. We face a leaf-curl problem in the early season and dieback later. Last year I had used Thuja 6 with little success. This year I have given one spray of Thuja 7 days back so far. Sending photos.
Farm Healthy plants around 60 % of crop
Plants with wrinkles & curls 40 % of crop Rare 0.5 % stunted plants
Should I continue to spray Thuja, and at what intervals? Are there alternatives? Please guide.
Dear Manish Saryam,
Thank you for your preference and resonance with holohomeopathy. The leave curl problems are related to the presence or viruses generally transmitted by whiteflies. So it is very important to intercalate every 5-6 plants with different accompanying plants, mainly Ruta graveolens, Rosmarinus officinalis, Foeniculum officinalis, Ocymum basilicum, to avoid the whiteflies. (This insect will be increased if you use animal manure fertilization). Sometimes, the agricultural producers are reluctant to intercalate the plants mentioned arguing the lack of space, but high vitality and productivity of the plants will be a fair reward for this extra effort on the part of the farmer.
My homeopathic suggestions are: soil nosode 6 CH at the beginning of the season, Calcarea carbonica 12 CH every two or three weeks foliarly, Ricinus communis (from the seeds) 12 CH when it increases the incidence of insects and application of hydrolate of leaves of Ricinus communis in microdoses foliarly and to the soil as a contribution of nitrogen, instead of cow manure or excrements of other animals. The plants are essentially vegetarian (eat plants in a state of decomposition in the form of compost) and are not mostly excrementivorous. The application of cow or other animal´s excrement in large quantities increases the presence of insects transmitting the virus. So the application of plant compost should be best.
Dear Radko Tichavsky:
I live in the southeastern United States, in a mountainous area. The elevation is 650 meters; annual high temp is 19.4°C; average low is 7°C. Average rainfall is about 0.9 meter. We have a type of hemlock tree named Tsuga caroliniana. It is an evergreen in the pine family (NOT Conium maculatum). A healthy tree can reach 21 meters. For two (human) generations, the trees are increasingly infested with woolly adelgid (native to East Asia). The hemlocks in this part of the country are being ravaged. The insect feeds by sucking sap from hemlocks and spruces.
There are two commonly used control options, one of which is toxic to beneficial elements in the soil and to wildlife (the insecticide is called imidacloprid). The other method is a spray with horticultural oil. Both obviously have their drawbacks; horticultural oil sprays may be effective but have to be repeated often, every year and expensive on large trees. Do you have any suggestion about homeopathic treatment?
Thank you for your help.
Dear Webster Williams,
The Adelges tsugae is a fairly persistent pest not only in Tsuga caroliniana but also in other types of Tsuga sp. Once infected the tree can die within three years. Treatments with neonicotinoids such as Imidaclprid represent an important risk for colonies of bees and other insects and generally produce greater imbalances in the holon. A. tsugae is very sensitive to some fungi that normally reside in forest soils, its pathogenic (maladaptation) action is a result of a disconnection of the holon (in this case between tree crowns and between the soil microbiota) because it is an exotic pest, an introduced organism. Soil fungi such as Lecanicillium lecanii and Beauveria bassiana (commercially available) are especially lethal to Adelges tsugae.
In order to control the insect, a two-stage bionosode application is performed: prepare a hydrolate of mulch from the forest soil in the part of the forest called attractor. Attractors are zones that are distinguished by a specially vitalized growth of the hemlock tree that are not unaffected by the pest. Attractors are places or areas where vitality intensifies and are an important source of beneficial organisms for the rest of the holon.
You can fill a 200-liter jar and add half the volume of the mulch and half the volume of water by adding two kg of brown sugar. Wait for about a week (during hot days it may be less) and then dilute this hydrolate in proportion of 1:100 in water by performing 100 turns with a wooden stick to the right and 100 turns to the left. This remedy is sprayed on the trees affected by Adelges tsugae, in three exposures with two weeks away. Once you observe dead insects, collect them and perform a hydrolate of them, dynamizing all the time in water to the 6 CH potency and apply the remedy by spraying it on the trees with the rest of the pests, finishing the second part of the application of bionosode and healing process.
I live in India (Rajasthan) and do Polyhouse Farming of cucumbers. Nematodes are a very big problem. We use earth in polyhouse. The fertilizer used is dnpk, Zn, mn, mg, copper,fe, etc and before sowing use cow, buffalo natural fertilizer.
Is there a way to solve this?
