ABSTRACT
Tomato, Solanum lycopersicum, is an important economic crop in India. Agrohomoeopathy contribute to the control of plagues and diseases, directly promoting increased production. In agriculture, homoeopathy helps to control the diseases of the plants by promoting the physiological activity of the plant. The Homoeopathic preparations can influence the growth, secondary metabolites production, essential oil yield and phytochemical profile when applied in the plants.
This study is to know the effect of homoeopathic medicine in controlling pests and effect on yield by Ocimum basilicum and Sambucus nigra on the most used crop Solanum lycopersicum. The potencies are 30CH and 200CH for each medicine.
It is observed that the medicine Sambucus nigra-200CH has shown greater increase in growth of the plant and also control in pests. Next to this is Ocimum basilicum-30CH where it shown the better yield than the other group of plants when compared with the natural growth of tomato plants and with fertilizer and pesticides use of other group of plants.

INTRODUCTION
The extensive use of synthetic fertilizers in agriculture is causing environmental problem. In this situation it is desirable to find out suitable agents, which would increase plant growth without compromising with the quality of plants and of soil. In homeopathy a substance, which produces morbid symptoms at high doses on healthy individuals, ameliorates the disease in a patient showing similar symptoms at ultra low doses.
In plants, the low potencies are to be applied for acute symptoms and damages in plants [6CH, 9CH] whereas the medium potencies for problems with the tendency to certain fruit trees [12CH,30CH] which are harmless for the user. This is important, due to the fact that use of agrochemicals and especially pesticides, frequently causes injury and sometimes death of farm workers. It is inhumane to use these chemicals if it is known that a poison can be inhibited by the same poison when it has been prepared homoeopathically and therefore one can avoid injury and death of many plants. It do not contaminate land or people and help support the regeneration of the ecosystem. The potencies do not injure micro flora and fauna or the aquifer mantles.¹
Agrohomoeopathy can also reverse damage already present in the ground because of the use of fertilizers or pesticides or excessive salinity. There is already scientifically verified evidence supporting the relevant of applying homoeopathic medicines to plants before and during sowing or directly on the ground.¹
Tomato plants are used in various experiments in order to know about the stress levels in it and also insect tolerance transgenic tomato plants are also been made. Through ages pests and plant diseases have remained a constant threat to the quantity and quality of overall crop production. Once correct disease is identified, by symptoms, proper control measures can be applied. Few diseases that usually occur in tomato plants are Late blight; Grey spot and bacterial canker.
Tomato leaf curl virus (ToLCV) causes 30-100% yield loss, this had stimulated research to find a suitable remedy. Use of Homoeopathic medicine psorinum in agriculture was to validate the potential of agro-homoeopathy in viral infection. Even the post harvest quality of tomato treated with high dilution preparations. The ultra dilution of homeopathic medicines can be used safely for various purposes. But precautions are to be taken before the use of these drugs. Proper selection of the potency of required drug this can be very cost effective alternative that can increase farmers income by lowering the input cost of chemical fertilizers and insecticides.²
Plants that help each other are grown together since ancient times, like tomato and basil, beans and potatoes, corn and potato and other plant and herbs. Ultra high dilution of homoeopathic medicines can be used safely for various purposes (Seed germination, betterment of soil health, growth of seedlings, flowering, fruiting and protection against diseases and to overcome environmental stresses). But precautionary measures (proper selection of homeopathic drugs and its potency, proper dilution of drug with water) must be taken before use of these drugs. Wrong drug selection can show detrimental effects on crops and it is believed that higher dilution of drugs (1: 500 or 1: 1000) with water is more effective for plants. If there is proper selection of drug and its potency, agrohomoeopathy can be an efficient and very cost-effective alternative that can increase farmers income by lowering the input cost of Chemical fertilizers and insecticides.²
Homoeopathic preparations are being used efficiently for increasing active principles in medicinal plants, plant detoxification for metals, increasing plant growth rate and productivity, plant metabolism and control of diseases.
The extensive use of synthetic fertilizers in agriculture is causing environmental problem. It is desirable to find out suitable agents which would increase plant growth without compromising the quality of plants and of soil. In homoeopathy a substance which produces morbid symptoms at high doses on healthy individuals, ameliorates the disease in a patient showing similar symptoms at ultra low doses.
Dynamisation or potentization (by process of trituration or succession) is unique aspect of the science of Homoeopathy that in comparison to simple dilution, even at higher levels, is more effective. It is a fact that the high potency of a drug is sometimes the best antidote for the effects of the crude drugs.
The main objective is to know about the effects of homoeopathic preparations Ocimum basilicum and Sambucus nigra on plant Solanum lycopersicum (tomato) as the medicine naturally improves the plant resistance against pests and helps to improve natural immunity of the plant and promotes growth without actual use of pesticides.
PREPARATION OF HOMOEOPATHIC DILUTIONS:
Direct use of homoeopathic drugs may lead to negative outcomes in agriculture. Drugs must be diluted with water and mixed properly before application. Drugs can be diluted with water at various ratios :100, 1:200, 1:500, 1:1000, 1:5000 etc. It was reported that at higher dilution there is no effect of vehicle (alcohol) remains. Sukul et al., (2012) reported that at 1:1000 dilution the effect of alcohol was eliminated but the main component of homoeopathic drug was active.³
DESCRIPTION ABOUT THE PLANT:
SOLANUM LYCOPERSICUM (TOMATO)4
Solanum lycopersicum is the edible berry commonly known as a tomato plant. It is originated in western South America and Central America. Tomatoes are significant source of Umami flavor. Various varieties are widely grown in temperate climates. They grow to 1-3 meters i.e., 3-10ft in height. The size of tomato varies according to the cultivator, ranging 1-10cm in width. The leaves are 10-25cm long, odd pinnate, with five to nine petioles.
Scientific classification
Kingdom: Plantae
Division: Magnoliophyta
Order: Solanales
Family: Solanaceae
Subfamily: Tracheobionta
Genus: Solanum
Species: Solanum lycopersicum
Binomial name: Solanum pimpinellifolium, Solanum cerasiform.
Effects of four homoeopathic medicines for human use were assessed in two centesimal dynamizations. (7CH and 13CH)
[Silicea terra (SiT), Natrum muriaticum (NaM), Zincum phosphoricum (ZiP) and Phosphoricum acidum (PhA)], and a control treatment (distilled water) on tomato plant germination, emergence, and initial development.5
Significant differences were observed in all the morphometric variables assessed in function of the different development stages, homeopathic medicines, and their different dynamizations. During germination, greater growth in stem length was observed with ZiP-7CH (5.5 ± 0.98 cm) compared to the control group (4.3 ± 1.10 cm).5
The tomato plants can also be homoeopathically treated by some mother tinctures in order to grow them in low sunlight region.5
SAMBUCUS NIGRA:6
Sambucus (samb)
Common name: Elderberry
Family: Adoxaceae
Synonyms: Elder, Black Elder, European Elder, European Elderberry and European Black Elderberry.
It is treated for Night shades (solanaceae)
Family- Caprifoliaceae/Adoxaceae. Tincture of fresh leaves and flowers.
GENERAL:
The leaves of sambucus have an unpleasant odor when bruised, which is offensive to most insects, and a decoction of these leaves is some used by gardeners to keep caterpillars from delicate plants. Sambucus was confirmed in the field after its description in the companion plant manuals. They grow in hedges in moist places. It was the favorite medicinal plant of Hippocrates. The active ingredient in its crude form is hydrocyanic acid.
Edematous swellings occur especially in twigs, stems and leaves. Inside the leaf the capillaries do not give passage to sap, and water logging results in these places. The plant can take up carbon dioxide but cannot release oxygen. Evaporation is increased during the day, but ceases entirely at night.
CLINICAL:
It is a general insect repellent particularly against caterpillars. Budworms, army worms. sawflies. Diamondback moth, web worm, cut worm, potato moth, cluster caterpillars, spitfire fly, strike and rot in sheep aphids.

OCIMUM BASILICUM: (BASILICUM)8
Basilicum
Common name: Great Basil
Family: Laminaceae
Synonyms: Osmium Basilicum
OCIMUM BASILICUM;
Treatment of Nightshades (solanaceae)
Basil- Ocimum is the companion to tomato, and which will protect the tomato against all pests and which will protect the tomato against all pests and diseases pertaining to it.
Basil Family: Laminaceae/ Labiatae. Tincture of the whole plant.
Previous studies on tomato plants with ocimum basilicum have shown that, with the dilution D6, C30, C200 and 1M four concentrations there is an increased content of beta – carotene, lycopene in tomatoes.8
GENERAL:
Basil, as a companion plant, protects tomatoes from both pests and diseases (almost as if giving them a wrap-around shield).For those who grow tomatoes as a commercial crop, and who have little space, making companion planting impractical, homoeopathic remedies can solve the problem.
Thus, bud worm, russet mite, whiteflies, tomato mite, red-legged earth mite and also the two-spotted mite can all be treated with ocimum basilicum. Anthracnose bacterial canker, fusarium wilt, spotted wilt, mosaic virus and blossom end rot can also be treated. It may not be suited to the treatment of other plants, because it is a companion plant to tomatoes. Ocimum basilicum is a constitutional remedy for tomatoes because of its special affinity. In companion plants, this phenomenon is frequently encountered, and can provide new insights into the relationships between the different remedies in the context of human treatment. From further study, much can be learned about the internal relationships between many different remedies that to date have not enjoyed such extensive scrutiny.
Other varieties of ocimum like ocimum canum, ocimum gratissimum and others are equally efficacious and maybe substituted for ocimum in their native countries such as India, Japan, Indonesia, Malaysia, Persia and Africa or South America.
Basil will also improve the taste of the tomatoes.7
CLINICAL:
All pests and diseases of tomatoes – Budworms, Russet mite, flies, mosquitoes, tomato mite, red-legged earth mite, two-spotted mite.7
EFFECTS OF PESTICIDES AND INSECTICIDES:
Farmers are at risk for airways diseases resulting from exposures which include organic agents and chemicals on the farm. Few data on airways disease and farm exposures are available from population based studies. Insecticide use has been linked to increased risk of non Hodgkin lymphoma (nhl).⁹
During their foraging activity, honey bees are often exposed to direct and residual contacts with pesticides, especially insecticides, all substances specifically designed to kill, repel, attract or perturb the vital functions of insects.⁹
Tomato hornworms are one of the most aggressive and troublesome pests to a farmer’s tomato crop and removed manually in many cases where only organic practices are allowed.7
Neural effects of insecticides that have repercussions on (a) cognitive functions, including learning and memory, habituation, olfaction and gustation, navigation and orientation; (b) behavior, including foraging and (c) physiological functions, including thermoregulation and muscle activity.⁹
The drug Basilicum, as a companion plant, protects tomatoes from both pests and diseases. For those who grow tomatoes as a commercial crop, and who have little space, making companion planting impractical, homeopathic remedies can solve the problem. Thus, bud worm, russet mite, whiteflies, tomato mite, red-legged earth mite and also the two-spotted mite can all be treated with ocimum basilicum anthracnose, bacterial canker, fusarium wilt, spotted wilt, mosaic virus and blossom end rot can also be treated.
The drug Sambucus nigra, in general the leaves of Sambucus are of very offensive odor this naturally repels the insects which contributes to pest free growth of plant. It particularly acts on caterpillars.
This contributes to increase in tomato yield. This makes to strengthen the plant to fight against these insects in which there’s increase in immunity of the plant and there will be no use of pesticides.7
DISEASES CAUSED TO TOMATO PLANT:
1. Tobacco Mosaic Virus, the only important example, remains active and viable even up to 3 years on tomato seeds derived from diseased plants.¹⁰
2. Phytophthoraparasitica produces oospores and causes brown to blackish discoloration of stem, which is termed as foot rot, which decays and rotten the plant.¹¹
3. Tomato wilt caused by fungi, verticillium, tends to be more severe at high nitrogen levels. It causes epinasty of the leaf petioles, wilting and yellowing of the leaflets.¹²
In Tomato, yellow leaf curl view infection was apparent in most control plants and a large portion of the nano gro product treated plants. The nano gro treated plants seem to be less infected, but it is impossible to tell if any resistance to this virus was impacted by the Nano gro treatment since infection was so widespread, and more time would have been needed to test this possibility. This gemini virus is spread by whitefly and is major problem for tomato growers. Overall, the results of Nano Gro treatment demonstrated a moderate effect on plant health and yield in tomato.¹²
