Ambrosia is an annual or perennial plant of the genus Asteraceae (Asteraceae). The plant is listed as a quarantine herb. It grows abundantly in the chernozem zone. Consider what a weed looks like and what methods you can get rid of.

Ambrosia polynnolistnaya - spring one-year weed, greenish in color with attractive, filigree leaves. In height, the grass can grow from 180-250 cm. The root system is well formed, especially the rod is able to sink to a depth of 4 meters.

The weed is distinguished by the highest vitality. The initial shoots occur in May, and in the period from July to August starts to bloom. Pollen plants adversely affects the well-being of people, which can cause allergies.

During the formation of flowers, the plant looks like a spike inflorescence. From 1 plant per year, about 40 thousand seeds fall out, which germinate the next year and infect the soil.

The high fertility of the weed, as well as its resistance to weather conditions, adversely affect crops.

Most grass grows in the south. In Russia, ambrosia grows in the Krasnodar and Stavropol Territories, the Volga region. But even in these parts, ambrosia is growing unevenly. For example, you will not see it on the Black Sea coast, it is widespread in the rest of the Krasnodar Territory. As ambrosia blooms, and the photo of the plant is presented below.

The weed expands more in the agrarian territory, in the fields, in the kitchen gardens, in the summer cottages, since it is easier to fight in populated areas with ambrosia.

The plant includes a sufficient set of biologically active elements, allowing the use of ragweed as a healing tool for the full range of diseases.

Leaves and inflorescences are fraught with a large number of secrets and the necessary qualities, namely:

  • it can be used in place of antihelminthic drugs, and it is one of stronger and more reliable drugs,
  • helps in the treatment of dysentery and diarrhea, disorders of the digestive tract,
  • acts as a means to relieve inflammation,
  • can reduce the temperature
  • it helps to treat malignant cancer cells, in particular, in the mouth and in the nose,
  • ambrosia is part of the contraceptive
  • the leaves can be used to heal wounds, cuts, ulcers, various lesions of the skin,
  • treats sciatica and osteochondrosis.

However, regardless of the benefits, the plant does a lot of harm. Let us analyze in more detail than this grass is dangerous.

Features and harm from plants

The characteristic of ambrosia is that it not only lowers the yield of agricultural crops, competing with them for the use of nutrients and moisture, but also causes great damage to people's well-being, activating pollen allergies.

When getting into the soil, the ambrosia seeds start to “take out” everything that is necessary, including moisture, for this reason, many other plants and agricultural crops instantly die near the ambrosia, dry out and do not form. Almost all landowners say “if a weed has grown on the ground is a tragedy”, since the ambrosia roots fall into the earth to a greater depth, the seeds that have fallen into the soil, keep their germination for many years. At the same time one shrub of ambrosia can produce up to 200 thousand seeds.

Particular damage to ambrosia in its pollen, being in the mucous membranes of the respiratory system, generates a powerful irritation and allergies, a characteristic feature of which is allergic rhinitis. Moreover, the impact on the respiratory tract can be so strong that it will cause asthma attacks. For this reason, it is not recommended to use ambrosia for treatment. To create products on the basis of ambrosia can only experienced herbalists or homeopaths using small doses of the plant.

In the presence of allergic reactions, especially to plants and their pollen, it is best to eliminate contact with the allergen. Here is how this weed plant can harm nature or man:

  • overdries the soil
  • creates a shadow by another plant, which as a result suppresses their formation,
  • if a cow eats this grass, then milk can taste bitter,
  • pollen causes severe allergies in humans.

On the ground, where only one shrub of ambrosia arose, after 3 years, it is absolutely possible that there will be thickets of this weed. Spores of plants can move at great distances, for this reason, the weed does not necessarily increase in the villa area, in order to cause allergies.

On the fields of grass ambrosia agricultural equipment efficiency, making it difficult to clean. In the mowing, she throws out the necessary plants, which leads to a reduction in the number of harvested grass.

If a person predisposed to allergies will inhale the aroma of ambrosia during the flowering period, such unpleasant signs will appear:

  • red eyes,
  • increased secretion from the nasal cavity and eyes,
  • heat,
  • there is a continuous sneeze,
  • rashes form on the skin,
  • it is difficult for man to take a breath.

However, in this “severe” weed, people found positive features. In alternative medicine, grass is used for bruises, diseases of the spinal column, disorders of the gastrointestinal tract, and even to reduce the heat. In addition, it is used to create substances that allow to determine the allergic response to pollinosis.

Fight plant

At home, Ambrosia has more than 600 natural enemies who are holding back its growth. Of these, there are both plants and insects. In our conditions, which are quite suitable for the weed, the enemy practically does not encounter obstacles. Ambrosia is not terrible drought, it is very fertile. As you already understood this plant is very stable.

Consider how we can get rid of the weed and whether it is possible. When you identify an ambrosia bush in the neighborhood, destroy it before the seeds appear. A small number of weed thickets can simply be mowed, but when you are late with this, and the ambrosia seeds wake up on the territory, you will be ready for a serious, long struggle, in which you need to use all possible methods.

Grass need to mow. This variant of the destruction of ambrosia is effective only in the period of the appearance of buds: when to mow the weed during the period of intensive growth, it will form 2-3 times more processes than you destroyed. For this reason, it will be necessary to mow again the growing ambrosia 3-5 times per season, not allowing it to bloom and form seeds.

Digging or removal with the root. The destruction of ambrosia with this method provides a good effect, however, you will need to tear off a weed a couple of years, as young sprouts will appear on the plot for a long time.

Chemical method You can’t destroy a weed on a wide terrain by hand, so gardeners often use a variant with the use of chemicals. These include water-soluble compounds of glyphosate: Prime, Tornado, Loren. Weed processing liquid is prepared in exact coordination with the management, but in resort areas, on pastures and in populated areas, the use of chemicals to destroy vegetation is prohibited!

Pushing by other plants. Experts advise to fight with ambrosia her own instrument, displacing the weed with grass for lawns and perennial plants. On pastures, it is possible to form the planting of long-term cereal grasses. For 2-3 years, such landings can completely silence ambrosia. The grasses that can conquer terrain from a weed include a plant, a foxtail, fescue, grains, sainfoin, wheatgrass. The grassy annual plant Sarepta mustard perfectly cleans fields from ambrosia.

Use of natural enemies, insects. In 1978, the ambrosia leaf beetle, a close relative of the Colorado potato beetle, was brought from America to China, Yugoslavia and Australia to fight against ambrosia. This is a dark beetle with longitudinal white stripes, eating not only ambrosia.

Despite this, while the results of the struggle are not very impressive, the experts do not give up: in the Rostov region, experience began, releasing 4,000 leaf beetles in the sunflower field. The selection of effective methods of dealing with ambrosia does not stop.

Methods of struggle

To combat ambrosia, three main methods are used:

The mechanical method is the most effective today. The plant is mown, dig up the roots and level the ground. It is impossible to completely remove the weed from the site in one year, it will take much longer.

The soil should be constantly inspected, as the ambrosia seeds can be brought into it again.

Mow the shoots should be before the emergence of seeds. Otherwise they will fall into the soil and you will need to carry out the procedure again. In this situation, you can mow many times, until the very end of the season. You should also repeat the procedure of pulling out and digging.

The chemical method of treating the plant with herbicides is used only when the weed is widespread on the plot, it is simply physically impossible to remove thick growth of plants by hand. Nowadays, you can find a lot of tools in stores that are used to combat ambrosia, but they all have certain restrictions on use (resort area, settlements, pastures).

The biological method is used for the gradual displacement of the weed from the site with the help of other plant species, natural enemies of ambrosia. In the place of weed can be planted:

  • alfalfa
  • fescue,
  • lawn grass
  • perennial cereals and legumes.

These plants within 3 years will naturally reduce displace ambrosia.

The use of insects to fight against ambrosia in our conditions is still experimental, since, for example, the ambrosia leaf beetle feeds not only on the leaves of the weed, but also on the shoots of other crops grown not far from the weed.

What kind of plant - ambrosia, and where it came from

Previously, ambrosia grew mainly only in North America. At the end of the 18th century, seafarers with red clover seeds brought it to Europe.

The first mention of ambrosia in Ukraine was recorded in 1914. A German doctor, Cricker, used her as a substitute for quinine. A little later, Denikin's army delivered it to the southeast. After World War II, ambrosia seeds spread throughout the territory of Ukraine by truck wheels - “Studebakers”. Over the next hundred years, ambrosia spread throughout Europe.

At the beginning of our century, ambrosia spread to the Volga region and the Black Sea region. From the south of Russia ambrosia confidently migrated to the north and east of the country. Due to the warming of the climate, the weed completely matures almost throughout the entire territory of Russia, which is why an allergy to ambrosia is a fairly frequent case.

Ambrosis damage

Despite the beautiful name, ambrosia brings a lot of trouble to landowners and ordinary people. Let's first understand what ambrosia is. Ambrosia is an allergen that can be fatal. During the flowering period, its pollen irritates the respiratory tract and makes breathing difficult. This is one of the main reasons why ambrosia was added to the list of quarantine objects.

Ambrosia also causes serious damage to garden and garden crops. The powerful roots of the plant suck up a colossal amount of water from the soil, depriving moisture of fruit trees and various shrubs. As a result, they gradually fade.

If ambrosia begins to grow on the field, then after a few years it will completely replace legumes, cereals and other forage crops. If ambrosia gets into the hay, its quality deteriorates. If you feed cows with such hay, their milk will have a sharp, unpleasant smell and taste.

Medicinal properties of ambrosia

Ambrosia, with its entire negative component, contains many different essential oils, vitamins, trace elements, beneficial compounds that help in the fight against certain diseases. It is often used to treat hypertension, febrile conditions, in the fight against diarrhea and dysentery. Also Ambrosia allows you to get rid of worms (harmful parasites), accelerates the healing of bruises and wounds. Research confirms that bactericidal activity is present in ambrosia. The plant helps to fight oncology zero and first degree. Of course, the harm from it is significant, however, and the benefits of proper use of ambrosia is great.

First Aid for Ambrosia Allergy

Allergy to ambrosia can be suppressed with the help of folk remedies or using antihistamines, which have many side effects and contraindications. Folk remedies that use only natural products with herbal ingredients, allow you to get a result that is absolutely identical to antihistamines, but the treatment will bring much less harm to the body, which plays an important role in the treatment of pregnant women and children.

Medicinal herbs are used, such as a series, nettle, yarrow, elecampane, and natural products, in which only one contraindication is individual intolerance.

If allergic reactions to ambrosia are found in oneself or one's loved ones, appropriate measures should be taken immediately. Allergies are accompanied by the following symptoms:

  • runny nose
  • eye redness and itching
  • tearing
  • itchy skin
  • hoarse and coughing
  • sore throat and sore throat.
Having found these signs, immediately take a pill of Aleron, loratadine, suprastin or another antihistamine. Next, choose how you will be treated for allergies to ambrosia, and, following it, heal yourself.

It is important to understand that allergies to ambrosia can lead to death. If you are prone to allergies, try to avoid weed accumulation sites, always carry an antihistamine with you and at the first sign of an allergic reaction, contact an ambulance.

Unrequited love in the vast expanses of Russian lands

As early as the last century, the seeds of ambrosia of the wormwood were imported to Russia by grain merchants from North America. And at that very hour, a one-sided romance of the weed and the Russian mother earth broke out.

At first, ambrosia got accustomed on the southern frontiers of our homeland (Krasnodar Territory), which, in terms of climatic features, approximate to American realities. Then, having shown enviable vitality and fecundity, as well as using the help of global warming, the weed began a victorious march throughout the territory of the Russian Federation.

Polynolifolia ambrosia is classified as a quarantine weed. Therefore, if in any raw material (seeds, wheat, rye, etc.) the presence of ambrosia is detected, it is forbidden to export it outside the region and the country. Having shown miracles of viability, the weed continues to cause irreparable harm to human health, causing persistent allergic reactions. The main allergen is the abundant pollen of ambrosia, which during the flowering period of the plant causes pollinosis and hay fever in sensitive people.

Ambrosia wormwood: general information

Annual plant recognized as spring weed. The color of ambrosia varies from light shades to dark green. There is a resemblance to the medicinal plant - wormwood.

Under favorable climatic conditions, a weed reaches the size of 180-250 cm in height. The ragweed ambrosia has a well-developed root system and the main taproot, which goes deeper into the ground by 3-4 m. Shows high vitality and germination of seeds (resistant to mowing, flooding and drought). The seed of ambrosia lying in the ground is capable of further development even after 40 years of oblivion. Weed shoots in large numbers appear in May throughout the entire growth area.

Ambrosia blooms in July-August, highlighting a lot of allergenic pollen. It contains a large amount of ambrosytic acid, which causes the strongest allergies in humans. Inflorescences of weed have an elongated spike shape. The period of flowering and fruiting in our latitudes is extended until October. The weed propagates only by seeds - self-sowing. One adult plant can produce up to 30-40 thousand seeds per period. Such fecundity and high resistance of ambrosia to the natural conditions of varminae is the main reason for placing it on the list of quarantine plants that carry a biological threat to the land areas of the Russian Federation.

Ambrosia wormwood - harm to nature and man

Where a beautifully named weed grows in large quantities, it is impossible to underestimate the damage caused by it to the surrounding nature and agriculture. Growing up, ambrosia develops a powerful root system that literally “clogs” the nearby cultures.

Сильное, высокое растение потребляет из почвы огромное количество воды и полезных веществ, чем сильно угнетает растущие по соседству культурные посадки. After the ambrosia, a dried and depleted land remains, on which nothing will grow without additional agro-measures. This weed can be called the "locust" of the plant world, because after it it leaves the "scorched", "dead" land.

Attention! A high strong plant of ambrosia of the wormwood protects small sprouts of cultivated plants from sunlight, thereby reducing or even destroying the future crop of gardeners and gardeners.

On the fields of agricultural use, this weed is the reason for the decrease in the productivity of agricultural machinery, seriously complicates the harvesting and at times worsens the quality of the field work.

On the territories intended for grass mowing and active pastures, ragweed ragweed replaces useful fodder grasses, thereby reducing the quality of harvested hay. If cattle eat ambrosia, the quality of milk decreases, and it also gets an unpleasant bitter taste.

For a person, ragweed is harmful due to its abundant allergenic pollen, which is released in large quantities during the weed bloom. If a person is prone to allergic reactions several times inhale the "magic" scent of this plant, the consequences will not take long to wait:

  • severe nasal congestion and heavy discharge,
  • tearing and redness of the eyes,
  • temperature rise,
  • agonizing sneezing,
  • itching around nose and eyes,
  • skin rashes,
  • difficulty breathing, in severe cases - pulmonary edema.

Ambrosia - useful properties and application

An inquisitive human mind even in such a formidable weed as a ragweed found in the forest, found positive moments and a real use. It contains a large amount of essential oils, vitamin and mineral salts. In folk medicine, leaves and stems, roots and plant seeds are used:

  • as a febrifuge
  • as a remedy for bruises and bruises,
  • with radiculitis and other diseases of the spine,
  • used to restore the activity of the gastrointestinal tract,
  • Some homeopaths have noted the positive effect of an ambrosia extract on cancer,
  • as a remedy for diarrhea and several types of parasites (worms).

The main positive property of ambrosia can be safely called the treatment of allergic reactions caused by it. The crippled, the and treat. On the basis of the plant ambrosia created drugs against pollinosis.

Basic countermeasures

Despite the identified positive properties, the damage caused by this weed is immeasurably great. Therefore, it is still necessary to ambrosia wormwood in their garden plots ruthlessly destroy. Let her place be in greenhouses and botanical gardens.

There are several methods of dealing with ambrosia:

  1. Manual method. If the struggle is conducted in a limited area of ​​the garden or garden plot, the best way to get rid of the weed is to uproot. It is a rather laborious method, but if you hold it before the start of flowering and fruiting ambrosia (when the super-viable seeds do not fall into the ground yet), then its effectiveness is very high.
  2. Chemical method The modern chemical industry provides a wide range of herbicides that can completely destroy both young and adult ragweed plants. However, it should not be forgotten that it is irrational to use this method of struggle on the territory of pastures and agricultural lands.
  3. Substitution method. You can fight a weed with his own weapon. It is necessary to sow the occupied territories with mixtures of perennial leguminous and cereal grasses (vetch, alfalfa, mustard, rape, etc.). For several years, these plants are able to completely expel ambrosia from plots and fields.

Under natural conditions of growth (North America) in ambrosia of the wormwood there is an enemy from the world of insects - the leaf beetle ambrosia. This bug with pleasure eats young sprouts of a plant. In Russia, this insect does not inhabit, but scientists are conducting research to study and create opportunities for the life of this "medic field".

Appearance history

On our continent, this plant came from North America. This event has occurred. at the end of the XVIII centurywhen it was brought to us along with seeds of red clover. Found it on the territory of Ukraine in 1914. At that time, ambrosia was used as a medicinal plant, instead of quinine.

After World War II, this plant was brought from Europe on truck wheels. As a result, for the last century, ambrosia spread over more than 5 million hectares. At present, the grass stubbornly spreads to the north and east of Russia from the Black Sea and Volga regions. Due to the changing climatic conditions, the seeds of this grass are fully ripe to ripen in central Russia.

Types of ambrosia

In nature there three kinds this grass:

  1. Ambrosia tripartite. This is a one-year weed species with branched stems and broad leaves. It begins to grow in early spring, quickly displacing other plants, both cultivated and wild. This species very quickly drains the soil cover. The flowering of this weed begins in early summer.
  2. Ambrosia wormwood. Annual grass looks very similar to common wormwood. There are instances reaching a height of up to three meters. The stem of this plant is straight, branched from above and pubescent with hairs. The leaves are light green below, closer to the top noticeably darkening. During flowering, it emits very harmful pollen.
  3. Ambrosia naked. This plant is very similar to polygoniferous ambrosia. It has good resistance to low temperatures, the developed root system does not freeze out even in extreme cold. The seeds of this perennial begin to germinate in May. The pollen of this weed is less harmful than that of the ragweed ragweed, but it still adversely affects human health.

Medicinal properties of the plant

However, besides the harmful properties, this plant has medicinal ones. The composition of ambrosia includes essential oils, vitamins and biologically active substances that help in the treatment of certain diseases.. As a juice, infusion and various extracts, it is used in the treatment of bruises and wounds, fever, dysentery and hypertension. Also, ambrosia is a good remedy for high temperature and inflammatory processes. It also helps with cancer at an early stage.

Negative qualities

The set of harmful qualities of this weed will more than block its useful properties:

  • Depletion of soil. It is necessary to inadvertently start one plant of ambrosia, as it will be impossible to get rid of it in 2−3 years This herb has a very strong taproot, which can reach up to four meters deep. Stems can grow up to 1.8 m in height, although, according to eyewitness accounts, there were also three-meter specimens. A powerful root system in the osprey with a no less powerful stem mass virtually blocks the development of other plants nearby. In proof, scientists presented experimental data that show that to grow one kilogram-mass of dry grass, ambrosia takes almost one ton of water from the soil. In addition, one copy of this grass impoverishes the soil by 1.5 kg of phosphorus and 15.5 kg of nitrogen.
  • Plant shading and extrusion. Ambrosia with its large foliage shields other cultivated plants from the sun's rays, preventing the latter from developing. This grass displaces fodder plants from pastures and meadows and, falling into hay, reduces its quality. When ambrosia gets into the food of cows, milk quality deteriorates.

Impact on human health

Ambrosia is a very strong allergen-weed. Its pollen can cause hay fever or pollinosis in humans. This disease is dangerous in that it affects the upper respiratory tract in both adults and children. The symptoms of this disease are: lacrimation, redness of the eyes, sneezing and runny nose, but the most dangerous may be laryngeal edema with the onset of asphyxiation. In this case, an urgent appeal to the doctor.

When pollen appears, practically the entire population living in the area of ​​distribution of this plant begins to suffer. For comparison, we can give an example: one adult ambrosia ejects up to one million pollen particles, and for the occurrence of allergy, 25 particles per square kilometer are sufficient. m of air. It even goes so far that people have to leave these places for a while. The children's organism may not cope with this disease, and then death is inevitable.

Plant description

The herb Ambrosia belongs to the Astra family, and can be both annual and perennial. It is quite attractive and decorative: beautiful elongated dark green leaves have a silver-green pad on the reverse side. Small flower baskets of different shades of yellow or green are collected in long racemes.

Common species

In total, more than 50 types of ambrosia are known.

But on the territory of our country there are three:

  • Ambrosia golokolosaya (or golometelchataya) - perennial plant up to 180 cm high with creeping rhizomes, characterized by the highest frost resistance. It survives in the most difficult conditions of growth, breeds root suckers and seeds, so its habitat is constantly expanding. The most common in Abkhazia, the Stavropol region, in the Volgograd, Samara and Orenburg regions and in Bashkiria.

  • Ambrosia wormwood - Annual heat and light-loving drought-resistant plant. Propagated by seeds. Height from 20 cm to 2 meters. Distributed in the Caucasus and in the southern coastal areas, most often found along roads and ditches, as well as among cultural crops.

  • Ambrosia tripartite - Another annual, quickly increasing the green mass. It was discovered somewhat later than the ambrosia of the wormwood, but it is rapidly spreading in many regions: its seeds are found in the grain supplied from the southern regions.

Note. The roots of annuals are pivotal, they can sprout into the ground to a depth of 4 meters. Pulling a weed out of it is not an easy task.

Ambrosia occurs in late spring or early summer, depending on the region and weather conditions. And after two months, it begins to actively bloom. In two or three months of flowering, each plant produces up to forty thousand seeds that remain viable for 5 to 40 years.

For reference. Seedlings can produce not only fully matured seeds, but also completely “green” - wax and milk maturity.

Harm to man

Ambrosia pollen is the strongest allergen. During its flowering period, which lasts several months, people with hypersensitivity to this plant develop hay fever (hay fever).

They suffer from all known manifestations of allergies:

  • Pruritus, rashes and redness,
  • Red eyes and tearing,
  • Hoarse breathing, shortness of breath,
  • Sneezing, coughing, runny nose, swelling of the nasal mucosa,
  • Soreness when swallowing.

Note. Ambrosia pollen sensitivity can develop even in people who have not previously suffered from allergies, if they inhale it for more than 10-14 days.

The most unpleasant is that these harmful plants are most common in the Crimea and other resort regions, where people go to heal. And those and others are attracted by the mild climate, the sun and the heat.

Therefore, in the resort areas often quarantines for ambrosia are introduced and they organize raids even on private land plots. When ambrosis is found on them, the owners are often penalized.

Specialized phytosanitary surveillance services are engaged in the mass destruction of ambrosia.

Seemingly so strict measures are explained by the fact that otherwise the struggle with the malicious weed loses its effectiveness. After all, it is a frost-resistant and drought-free plant that produces a huge amount of seeds, and its pollen is easily transported over long distances, endangering people even outside of its mass growth.

Harm to agriculture

Ambrosia damages both livestock, crop production, and even the natural flora of the region in which it lives.

  • The long core root of ambrosia sucks all nutrients out of the soil, depleting and drying it. And the leaves actively absorb moisture. Therefore, the neighboring plants quickly die. This weed is especially harmful to cereals, legumes and oilseeds, sharply reducing their yield.

Ambrosia in the field

  • Skeletal branches of ambrosia clog the cutting elements of agricultural machinery, reducing the harvesting performance and its quality, increasing the costs of forced harvesting.

Weed harms even agricultural machinery

  • Stern meadows littered with ambrosia lose their nutritional value due to the depletion of the soil. Cattle do not eat feed in which the content of this plant is too large. And if it eats, the quality of meat and dairy products deteriorates, acquiring a bitter aftertaste and smell of essential oil.

Beneficial features

One hundred years ago, ambrosia was grown in Russia specifically to combat a dangerous disease - malarial fever.

It really can be useful and is used in traditional medicine as:

But the use of drugs based on it is possible only in the absence of allergy. Therefore, preliminary tests for allergens are necessary.

Note. In addition to allergic reactions, ragweed essential oils with prolonged inhalation can cause headaches.

Ways to fight

If you do not fight this weed, it will very quickly fill up with everything in the neighborhood, displacing other crops. To do this, use all possible methods - mechanical, chemical and biological.

  • Mechanical methods are the most effective, effective and safe. They consist in pulling, digging and mowing weeds with their obligatory destruction. It is necessary to do all this before the appearance of seeds, and repeatedly during the season. Because, as already mentioned, seeds of any degree of maturity can germinate, even for several years that have lain in the ground. In addition, they can be brought to the site by wind, birds or with seeds of other plants. Therefore, if you at least once noticed this plant on your plot, you will have to inspect the soil regularly.

  • Chemical methods based on weed treatment of weeds are not always acceptable. They can not be used in resort areas, pastures, in the territory of settlements, especially if the ambrosia colonies occupy a large area. But on personal plots with pinpoint infection, this method works better than others.

Chemical control methods are unsafe for humans and animals.

  • Biological methods consist in the use of natural ambrosia enemies, which include both other plants and insects. At home, the growth of such enemies in ambrosia is several hundred. We have to help her fight lawn grass, fescue, alfalfa, and other perennial legumes and cereals. They are able to completely replace ambrosia in three years. With insects harder. There have been attempts to use the ambrosia leaf beetle, but he does not disdain the shoots of other plants.

Conclusion

Not always by the appearance of the plant, it is possible to assess its danger to itself, to the people around and to garden crops. But if you know them "by sight" and understand what to do to destroy them, you can prevent the spread of these harmful cultures. We hope the information contained in the article was useful to you, although we wish that it would never be useful to you.

Origin

Seamen from North America brought the seeds of ambrosia at the end of the 19th century. Ambrosia came along with red clover seeds. The first plantations were in the Volga and Black Sea. Gradually, the grass spread to the eastern, southern and northern regions of Russia, to Ukraine and the North Caucasus. The accelerated spread occurred after the Great Patriotic War, when the wheels of the transport moving around the country carried with them the seeds of ambrosia.

Motherland

Warm climate contributes to the growth and spread of weed. For this, he chooses agricultural fields, yards, pastures, roadside sites, meadows, vegetable gardens, vacant lots, landfills.

Ambrosia (Ambrosia) - a representative of the genus of annual or perennial weeds, numbering 50 species of plants. Included in the Aster family. It is classified as a dangerous quarantine weed that has captured the whole world.

The name "Ambrosia", which translates as immortality, is derived from the fragrant ointment "Food of the gods", which was used by the gods of ancient Greece for body care. She bestowed youth and immortality.

Ambrosia

The appearance of the grass is very similar to ordinary wormwood. In ambrosia, a straight trunk covered with small grooves. It grows up to 1.5 m in height, and taproot goes into the ground to a depth of 3.5 m. Gray-green, pinnately dissected leaves up to 15 cm long. At the base of the plant leaves have a darker shade than the top. Stem and leaves slightly pubescent.

During flowering from July to the third decade of October, it produces branchy inflorescences in the form of a panicle of spikelets with small flowers that emit a large amount of allergenic pollen that is far from being carried by the wind. Flowers gay. Men are colored yellow-green, while women are under them, at the base.

Appearance

Seed ripening begins in August. Их количество просто огромно и достигает 40 тысяч.Before germination must pass the rest period, which lasts 4-6 months. Seeds of wax and milk maturity also germinate.

Young plants are very similar to the marigolds popular with gardeners, because people sometimes make mistakes. Adult shrub resembles Chernobylik, a type of wormwood.

Distribution features

Weed quickly fills the territory, spreading the seeds, and it is very difficult to fight it.
The vitality of the plant is associated with several factors, including:

  • The absence of insect pests on the territory of Russia and Ukraine. After all, they remained in the Americas.
  • Ambrosia propagates with amazing speed. Ambrosia seeds ripen in the process of flowering and have almost 100% germination. It seems incredible, but 1 ambrosia bush can produce 50 thousand plants.
  • The long root is able to extract moisture from the deep layers and ensure growth even on dry soils. Therefore, drought weed is not terrible.
  • After cleaning the plantation, the seeds preserved in the ground can germinate even after 50 years.
  • Even immature seeds germinate and give life to a new plant.
  • Seeds germinate on any soil. It is enough only a slight friability of the upper layer and plenty of sunlight

This feature quickly turns the infected area into continuous thickets. A tall bush with thick leaves and a strong root crowds out the rest of the vegetation nearby. Even in the distant neighborhood of ambrosia, crop yields are significantly reduced.

It is important to know that the developed ambrosia root system pulls all useful components out of the ground. For several years, the soil is depleted and becomes unsuitable for growing crops for agricultural purposes.

Soil depletion occurs under the influence of a number of factors:

  1. Drying of the humus layer
  2. Reduced soil fertility
  3. Shading

The effect of ambrosia on meadow grasses by suppressing their growth and subsequent displacement leads to the loss of useful areas. In contaminated areas, harvesting is difficult. Cereals with admixture of ambrosia seeds are prohibited for export to other regions. When mowing alfalfa, millet, Sudan grass, ambrosia seeds reach their maturity. They get into a heap when cleaning and litter it.

Ambrosia impurities in fodder hay negatively affect the quality of milk in cows and goats. There is an unpleasant smell and taste.

Harm to health

Ambrosia is the most dangerous for human health during flowering. Poisonous pollen enters the air and causes allergic manifestations in a large number of people. Symptoms of allergy include runny nose, inflammation of the mucous membranes of the eye, accompanied by tearing, rhinitis, cough with asthmatic attacks, headache, high fever, skin irritation and itching. Some people respond to an allergen by changing their symptoms.

Allergy

The level of pollen allergenicity depends on its size and concentration of allergens. The pollen has a microscopic size and easily penetrates the lungs. One plant can secrete several billions of poisonous pollen particles.

Allergenic plants were classified according to the strength of their impact, which is determined by the allergenicity index. Ambrosia assigned a maximum index of 5. An attack of the disease provokes a content of 5 units of plant pollen in 1 m3 of airspace. The harmful effects of other plants begin at a much higher concentration.

Currant and plantain, which have anti-allergic and anti-inflammatory effects, help to mitigate the effects of a powerful allergen.
