So, the hogweed plant is perennial poisonous flower, which became famous today for its therapeutic effect. It helps to cope with many illnesses and problems of the body. This plant was brought from the Caucasus, and spread throughout Russia.

What is a hogweed, where did it come from?

There are many types, here are the most common ones:

  • Hogweed Sosnovsky - grown in Europe, used as a silage and feed for cattle. He gave a specific flavor to the meat, the milk of animals that were eaten by the hogweed. This kind is considered very poisonous.
  • Siberian Hogweed - first learned about it in 1819 in the sowing sheet of the London Botanical Garden. But alas, the plant did not receive wide distribution.
  • Hogweed Mantegazzi - This is the most common type. About him learned from the mention of the Royal Botanical Gardens. This view very quickly flooded Europe. This species is also very dangerous.

Did you know that hogweed has been used for borscht since ancient times?

The leaves of the young plant were added to various vegetable and meat soups. Mistresses pickled shoots, and candied fruits were harvested from the stalks. Before drying the leaves, they were first soaked to remove all essential oils and coumarins. They also got sugar from the plant, and then they drove vodka from it. Still in the Caucasus, hogweed is the main edible plant. Scalded grass trunks with boiling water and served as a separate dish. Sometimes barrels are served roasted. Hairy Hogweed - very famous seasoning. It is used in the manufacture of cheeses in the Caucasus. But before you use, it is customary to scald, salt and boil.

What does a hogweed look like?

The trunk is hollow inside, ribbed outside and covered with a lot of unpleasant to the touch hard hairs.

Its branches are at the top, creating a large, white, fluffy flower. The grass has a pleasant scent that can be confused with the scent of flowering home plants.

Hogweed ordinary differs from other plant species in that it has rather long and powerful roots. These roots penetrate rather deeply into the earth and are saturated with groundwater.

Its leaves are very large. One such leaf grows over the summer by 0.5 meters in length. Hogweed stalks common covered with scales, exactly the same as on the trunk. The plant begins to bloom at the end of June or July. The white flowers of the plant are gathered in a high umbrella, and its seeds are located in it.

The fruits of the plant fully ripen by mid-August. Before this time, collecting fruits is not worth it, as they will not have time to fully gain vitamins and nutrients for the treatment of internal organs and skin diseases.

Where grows the hogweed?

This is a rather heat-loving plant that lives in central Russia. And often the grass is found in Altai, the Caucasus, the Urals and Siberia. Due to the fact that hogweed ordinary breeds self seedingYou can meet him by the road, and under the fences, and along the houses, as well as in heavily overgrown bushes in dense forest.

To date, there are about 70 species of this plant, each of them has toxic substances, acids and trace elements. Get rid of diseases such as: burns, blisters, diseases of the gastrointestinal tract, can only be after the attending physician will make the correct diagnosis and write out a prescription. In other cases, the hogweed is dangerous to health, which is why it is not recommended to take decoctions and infusions of this plant on your own.

What harm can hogweed cause?

For the first time, people faced a big problem when it began to grow outside the experimental plots. This is because it is almost impossible to remove it, and if you try to get rid of it, you can earn serious damage.

The destruction of the plant has become more like to war with injuries, burns and even death. People often underestimate the damage from simple contact with a plant; they think it looks like a nettle burn.

Even a non-professional cannot distinguish a poisonous plant from a safe one. Hogweed harms not only through contact with it, it is also a very strong respiratory allergen. It contains substances that can increase the skin's susceptibility to ultraviolet radiation hundreds of times, thereby causing severe burns. Because of this, it is dangerous on a sunny day to “burn”, even if you are wearing pants or a thin summer dress, it will not be a barrier to burn. To get a burn, a simple contact with the juice that is released from the fractures of the plant is enough.

But how will this happen if we do not deliberately break the plant? The leaves and stems of the plant break even from simple pressing when you walk through the thickets. If you saw it in your area, take action immediately. Let him even be on foreign territory, but not so far from your home. You can be sure that soon the hogweed will reach your site. Let us return to the burns, they may appear not immediately, but after an hour or even several days.

I will give an example of several signs by which you can understand that you have burned:

  • Severe redness will begin.
  • You will feel a slight itching and burning in the area of ​​the injured area.
  • Redness will be replaced by increasing blisters, with a clear liquid inside.
  • Increase body temperature.
  • Light feeling of discomfort in the body.

By the given symptoms, injury after contact with a hogweed, resembles a normal burn second degree. In this case, an urgent need to consult a doctor, in any case, do not self-medicate, otherwise the blisters, which burst, can get an infection, begin to fester and remain scars for life.

In any case, you need to take several actions, even if you do not feel any discomfort:

  • To begin, rinse well the damaged area of ​​skin that has come into contact with the plant under cool water.
  • Wipe the skin with alcohol, vodka or any alcohol-containing composition. If nothing of this is not at hand, then fit weak potassium permanganate solution or lotion with furatsilinom.
  • Take a cloth and cover it with the affected skin to cover it from the sun for at least two days.
  • Even if you are not allergic, drink antiallergic drug.
  • Lubricate the burn with some cream or foam (Panthenol or Rescuer helps well).

You must call a doctor, especially if you suspect a burn of the eyes, mouth, mucous membranes and inguinal region. In order to warn against danger, when going outside the city or to those places where the hogweed grows, tell the children and acquaintances what it looks like to minimize the risk of injury. Despite all the cons of the plant, he has a few advantageslet's consider them.

What helps to treat the hogweed?

The plant helps to cope with a variety of pathologies and disorders in the body. It is important to remember the following: treatment can only be prescribed by a doctor who takes into account the peculiarities of the patient’s body and makes an accurate diagnosis of the disease.

So, the diseases that are treated with cow parsnip:

  • epilepsy,
  • burns, boils, wounds,
  • gynecological tumors
  • jaundice,
  • asthma,
  • lymphadenitis,
  • kidney inflammation,
  • dysentery,
  • cholelithiasis,
  • increased appetite
  • scabies,
  • rheumatism,
  • convulsions.

Various broths, teas, and trays are prepared from the plant. Treatment depends on the severity of the disease, as well as on the patient's condition. This plant has contraindications. Pregnant women and childrenshould not be consumed inside Hogric acid preparations, without indications for use. And it is also important to remember that everyone is obliged to comply with the prescription prescribed by the attending physician, otherwise overdose threatens with complete failure of some internal organs.

How to deal with an uninvited guest?

On the territory of our country, measures are being carried out for the mass destruction of horshevik. Citizens who allowed the spread of hogweed on their sites, put fines. But so far the struggle has been unsuccessful. This is explained by the fact that not all people know how to remove the plant once and for all.

The most powerful weapon in the fight against it is the spit. Mowing is desirable in the dark, or in cloudy weather, when the humidity is high. Do not forget to wear waterproof clothing, a mask, goggles and gloves (preferably not made of cloth).

The second effective weapon is fire. Hogweed Fruit burn very welldue to tar content. It is advisable to dry the fruit first. To avoid a large growth of hogweed, its seedlings are dug out in the spring. Its seeds can be stored in the ground for many years. "Expel" they can be weeding, plowing, plowing, disking, etc.

If you act decisively and persistently, the result will not take long. Sooner or later, humanity will force the hogweed to disappear once and for all. Here is a small story about this plant. Take care of yourself and your loved ones!

Poisonous plant hogweed. How to recognize? A photo

How to recognize that in front of you a poisonous plant hogweed? There are various descriptions of how to distinguish poisonous species from harmless ones, but since there are about 70 species in the Horshevik genus, this is not so easy to do. In addition, in order to better consider the plant, you should get close to it, and it is extremely undesirable to do this, otherwise you can cause serious harm to your health.

For acquaintance with a plant it is better to use a photo of a hogweed poisonous. Its main external signs are:

  • large, sometimes up to 6 meters tall,
  • thick, branched at the top of the stem,
  • huge (up to a meter) leaves with segments of various shapes,
  • large, sometimes up to 80 cm, beautiful inflorescences in the form of umbrellas.

Hogweed often grow large thickets.

In any case, if there is no intention to use the plant for food or medicinal purposes, then approach and consider it not worth it.

The dangerous hogweed poisonous?

The poisonous species of Hogweed are a real threat to the health, and sometimes even human life. The danger is not only the sap of the plant, but also its pollen, odor (odor) and even dew.

Hogweed juice, falling on the skin, due to substances in its composition, increases its sensitivity to ultraviolet radiation. And as a result, in a very short period of time, you can get a severe sunburn with numerous blisters up to grade III. There have been cases of death in children with multiple burns.

The danger is not only the juice of hogweed, but also its dew. Even a simple touch to the grass of the hogweed can cause severe burns. Such injuries heal for a very long time and can leave behind scars and scars.

Sometimes burns from contact with the plant do not appear immediately, but after some time, therefore, when going out into the countryside, especially with children, inspect carefully the place where you plan to stop, whether there is a dangerous plant there.

Harshweet pollen, which is able to penetrate even through clothing, causes serious consequences for the body. Juice or pollen when injected into the eye can cause blindness.

Inhalation of hogweed pollen or essential oils can significantly harm the respiratory system and even be fatal. The consequences of such toxic effects are laryngeal swelling and asphyxiation.

The following symptoms are signs of intoxication (poisoning) of the Hogweed: headache, dizziness, nausea, vomiting, fever up to 40 ° C. Excessive exposure in the long run can threaten vitiligo disease.

If contact could not be avoided. What to do?

If contact with a poisonous plant could not be avoided, then it is necessary to act immediately:

  1. Wash the affected area under running water, preferably using soap.
  2. Treat with alcohol or alcohol-containing substances. You can use a weak solution of potassium permanganate or furatsilina.
  3. Lubricate with Panthenol, sodium usninat (on fir balsam) or syntomycin emulsion.
  4. The bandage should not be applied.
  5. If you are outdoors, outside the home, cover the place of injury with a light cloth to avoid ultraviolet rays. Also within a few days should protect this area from the sun.

If the burn is small, it can be limited to the measures described. If you have been exposed to allergies, the area affected is significant, juice, pollen, etc. Plants are caught in the eye or on other mucous membranes, and if the child has suffered, it is necessary to URGENTLY seek medical help.

Poisonous hogweed. Growth features

Hogweed - very unpretentious and resistant to adverse effects of the plant. In the first year, it is fixed in the soil, growing powerful, up to 1 m. Root, and on the surface is a modest small bush of several medium-sized leaves. This time, as well as the early spring, is most favorable for combating poisonous borshevik. In subsequent years, the plant gains power and height, growing 10-12 cm per day!

The fight against poisonous parsquim is hampered by its toxicity. In addition, the plant is not only extremely resistant to various chemicals, but even able to adapt to them. If you do not destroy mowed grass with unripe seeds at the time, they ripen independently, sprinkle and germinate.

Hogweed winters well, withstanding even ten degrees of frost. In addition, he even uses his own fallen leaves for the winter and uses grass as food for himself in the future as well as for his offspring.

Hogweed is also dangerous for other plants. Separating toxic substances, including into the soil, it thus prevents the germination of seeds of other plants, ensuring the germination of their own. The huge leaves of Hogweed capture up to 80% of the light, creating a shadow and thus suppressing the existence of competing plants. A large number of seeds, a high percentage of germination and the preservation of their germination for 2-3 years also contribute to the rapid spread of hogweed.

The destruction of the poisonous hogweed

The fight against poisonous parshevik is a difficult but necessary task, taking into account its danger to human health, as well as to other plants. In this type of work, it is imperative to wear rubberized or other waterproof clothing with a hood, shoes (or better boots) that completely cover the body. Also, do not forget to protect your eyes with glasses or a protective mask, and the hands of gloves or gloves. Do not be superfluous to wear a respirator or cotton-gauze bandage.

All types of work on the destruction of hogweed should be carried out in early spring, before the flowering plants. And of course, one should not allow the spread of this plant, because with single specimens it is much easier to fight than with extensive thickets.

Let us examine some ways to destroy the poisonous hogweed.

Plowing and weeding

If thickets of Hogweed are extensive, then a good way is dumping plowing in early spring. Then the raised roots are selected manually. After 3-4 weeks in the presence of new shoots from the preserved roots, plowing is repeated.

In order to fight against poisonous parshtvik in the fall, plowing should not be carried out, since in this case the seeds of the plant remaining from the summer will fall into the soil and germinate.

Black film

If the lesion is not too extensive, then a black film (100 microns) is used. In the spring, when all the weeds have already sprouted, cover the affected area with a film, flatten the edges with bricks or sprinkle with earth. The black color prevents the access of light and under the influence of the sun rays under the film creates a greenhouse effect that will destroy the plants. In June, the film can be removed, and the site dig up.

Lawn grass

In the spring, mow all the weeds on the plot, cover it with a geopolitny top and pour a five-centimeter layer of earth on which to plant lawn grass thickly. At the same time, it is important that the ground for the flooring be from the site not affected by the Hogweed. Another condition for a successful struggle is the absence of a poisonous plant in neighboring areas.

Chemical Treatment

Treatment with chemicals is carried out as extensive thickets of poisonous cow parsnip, and single plants.

When shoots of hogweed appear, but before flowering begins (this is important!), Extensive thickets of plants are sprayed with solutions of herbicides such as Roundup, Tornado, etc. A double concentration of the solution should be used, since the plant is EXTREMELY LIVING. The treatment is carried out very carefully: spray stalks, leaf rosettes, leaves, shoots and umbrellas.

Within two weeks it is necessary to carry out two treatments.

To fight against individual specimens, special preparations are inoculated (injected) into the stem of the plant with a syringe. To do this, use "Arboricide" or other similar drugs. Good results showed the use of acid from the battery.

Also, such an inoculation should be done after mowing individual adult plants into the remaining stump to prevent the emergence of shoots.

Dangerous species for humans

There are about 70 species of plants. На территории России встречаются только некоторые сорта, среди которых есть как опасные, так и безопасные. Опасными для жизни и здоровья человека являются следующие разновидности:

  • Wild cow parsnip is a plant reaching a height of up to 2 meters, which can be found in the southern regions and foothills. Blossoms over 2 years.
  • The hogweed of Sosnovsky is a very tenacious three-meter bush, characterized by a large amount of greenery, large light or pink flowers. May bloom for 2 years, but some types of shrubs are perennial. It blooms once in a lifetime.
  • Mantegazzi Hogweed - 6 meter grass, the most poisonous of all. The perennial culture covering entire territories has become widespread in the Caucasus. Differs in green fruits and blossoms in white.

Finding green growth in their area, they should be carefully removed. The plant is dangerous for other crops, able to crowd out and inhibit their development. Where the shrub grows, as a rule, other plants do not survive: because of the Hogweed, many farmers survived the agricultural crisis.

Safe varieties

Harsh species of Hogweed growing in Russia:

  • Siberian hogweed. Blossoms in various regions of the Russian Federation. This hogweed flower has a green or yellowish color, as well as small round-shaped fruits.
  • Dissected - grows in Siberia, on the coasts, in the zone of forest-steppes. It has white large flowers.
  • Shaggy - able to grow in length up to 1.5 meters. It is found in Asia Minor, in the Caucasus, in the Crimea. Blooms white.

To distinguish the hogweed poisonous from other safe varieties can be described in its description. Cultures are distinguished by flowers: in Siberian, they are greenish-yellow, with thin, pointed leaves.. Sosnovsky flowers are usually white. In addition, dangerous types of bush are much larger in size and can reach human growth; to the touch, the edges of the leaves are rough and torn; the stems have purple blotches with small fibers.

Beneficial features

The herb hogweed has long been known for its healing properties. The furocoumarins included in the composition have bactericidal abilities, therefore the plant is often used for removing worms in animals. In addition, the roots are used for the manufacture of psoralens - special substances that treat psoriatic plaques.

Also, the herb is effective against ulcers and purulent lesions, asthma, epileptic seizures. From the rhizomes of the culture are made decoctions for the treatment of pain in the liver and eliminate jaundice. Hogweed together with other cultures is used in the manufacture of silage for cattle.

Dishes with the addition of leaves and roots of shrubs have a pleasant aroma and taste.

Application

The plant is used in the treatment of many nerve pathologies and skin diseases.. Shrub is used as a sedative, with convulsive manifestations, epileptic seizures, gallstone disease and inflammatory processes in the kidneys.

Medicinal infusions are used during disorders of the digestive system, dysentery, to improve appetite. Trays of fresh leaves will help with scabies, as well as for pains provoked by rheumatism.

Broths based on rhizomes successfully treated:

  • lymphadenitis,
  • gynecological neoplasms,
  • jaundice
  • bronchial asthma,
  • liver disease,
  • gallbladder disease.

Before applying the culture in the treatment of diseases, it is necessary to make sure whether the hogweed is poisonous.

You should not use the shrub for therapeutic purposes with individual sensitivity to essential oils and other components.

Green thickets can be found on the coasts, fields, in vegetable gardens. Grass is considered the most dangerous in the hot season when flowering.. The danger of a hogweed for a person is necessary for everyone to know.

A significant danger is the juice, pollen, and the scent of shrubs, which can provoke allergic reactions with serious complications.

The essential oils and coumarin, penetrating into the skin, reduce the protective properties of the skin to the sun's rays. In this case, the person does not suspect that he suffered a severe burn, and is exposed to poison.

Even a light touch to the juice secreted by a plant can provoke a severe burn. At the slightest contact with the skin, urgent measures need to be taken: a burn can appear after a while, leaving behind dangerous consequences.

When dizziness, nausea, vomiting, headaches appear, it is already late to do something. Burned skin heals for a long time, blisters may turn black and last for about a month, leaving scars behind. In addition, severe relapses are possible.

Bush pollen has the ability to penetrate things. Once in the eyes, the liquid often provokes blindness. With a strong accumulation of coumarin increases the likelihood of vitiligo.

Symptoms of burn in contact with thickets are:

  • significant skin redness
  • covering the affected area with blisters containing liquid
  • the appearance of itching and burning,
  • increase in body temperature
  • general deterioration.

Most often, after contact with a hazardous crop, a diagnosis is made of a “2 degree burn”. When infected with blisters, the wound can fester and leave scars and scars.

Some grass species belong to poisonous plants that can harm the human respiratory system. The bush can be a health hazard and is often the cause of deaths.

The ingress of harmful varieties in the respiratory system leads to respiratory allergic reactions: the larynx may swell, which often ends in suffocation.

A particular danger is the culture for the elderly, children, people with weakened immune systems, as well as blond women with light skin. In the area of ​​increased risk are allergies, which are sensitive to essential oils.

First aid measures

If contact could not be avoided, and juice or pollen got on the skin, urgent measures should be taken:

  • wash the affected areas with plenty of water using soap;
  • to disinfect the skin with alcohol and other alcohol-containing agents, and also potassium permanganate or furatsilinom,
  • lubricate the skin with panthenol, synthomycin, fir balsam.

Do not bandage the wound when providing first aid. Immediate treatment to the doctor requires the ingress of toxic substances on the mucous membranes, especially in the eyes.

After contact of flowers, leaves or pollen with skin Direct sunlight with the affected area should be avoided for two days..

To avoid burns and other dangerous conditions, do not touch the plant.

Ways to fight

It is not recommended to remove the shrub stalks after flowering: it can become useless and cause severe burns on the hands. It is possible to reduce the active growth of the undergrowth by collecting it in a heap and burning it. Mowed grass should not be left waiting for it to dry. Thickets can grow again, get seeds and continue to grow. Even unripe fruits can cause new growth..

Mowing fully ripened bushes is not recommended: this can lead to their active growth, spreading over the nearby territory and an increase in the number of fruits on the ground. Also eliminate the growth should not be in the wind.

The fight with shrubs is carried out in special clothes, covering all parts of the body.

The most effective ways to get rid of thickets are the following:

  1. Pruning buds. Cut buds should be after inflorescence, near the base. This method will be effective for small bushes. Cutting is considered dangerous, as there is a chance that pollen will be on the body and face..
  2. Burning is applied after seed ripening. To do this, the bushes pour fuel and eliminate the central inflorescences. When ignited, the bush produces essential oils. In order not to provoke a negative reaction of the respiratory system, burning is carried out in calm weather, using a respirator.
  3. Use of herbicides. Processing is carried out at the occurrence of shoots, before flowering bush. With the appearance of the first seeds, this method may become useless. Herbicides show efficacy in frequent and strong treatment of petioles, rosettes, leaves, shoots and umbrellas.

The period of grass flowering is the best time to get rid of thickets. The flowers contain a large number of seeds, from which, soon, new cultures containing poisonous juice will begin to grow.

Hogweed is a poisonous plant that should be disposed of in time, not waiting for it to harm health. This should be done very carefully to avoid severe burns.

How did he come to us?

Hogweed is a genus of umbrella family plants. About forty species of hogweed grow in Russia. Everywhere and more or less the Siberian hogweed and common hogweed have always grown. Previously, their stems and leaves were used for food, for example, for borscht, and young shoots generally ate just like that (I personally know the people who did it). And of course, the hogweed went to feed the cattle.

In the 1940s, another species of this plant was described in the Caucasus - the hogweed Sosnovsky. It seemed promising for agriculture because of its rapid growth. Hogweed Sosnovsky began to plant in other parts of the country (including in the suburbs). But then it turned out that cows do not favor this kind of hogweed, and refused to cultivate. However, the plant managed to get into the wild. While everything was fine with agriculture in the country, the fields were thrown open, something was planted, there was no problem. But in the early 1990s, agriculture fell into decay in the Moscow region and in other areas of the central belt. The fields began to overgrow, and the hogweed of Sosnovsky - to actively capture them. He did not interfere with other plants, and the sun was a lot. From the abandoned fields, the hogweed has spread to other territories, and now it can be found almost everywhere. Due to the rapid growth, the hogweed of Sosnovsky practically does not leave other plants a chance of survival.

What is dangerous and why?

Hogric juice is dangerous. It contains furanocoumarins - substances that increase sensitivity to ultraviolet radiation. If the juice of hogweed got on the skin, then even in the bright sun there is a strong sunburn right up to the blisters. This is the main problem. If the juice of Hogweed gets into the eye, then even a minimal dose of ultraviolet radiation will cause a burn or even blindness ...

How to distinguish a poisonous hogweed from non-poisonous?

Siberian hogweed is a fairly common and completely safe plant. It also contains furanocoumarins, but in much smaller quantities. Therefore, it is dangerous only for people with individual intolerance. How to distinguish it from a poisonous relative?

Three main markers: size, flowers, stem. Siberian hogweed grows to a half to two meters. Sosnovsky's hogweed is the largest umbrella plant, it can grow up to four meters, besides it has a very thick stalk. At the base, it can reach five to seven centimeters in diameter. In the Siberian Hogweed flowers are greenish-yellow, the plant itself has a pleasant aroma. In the poisonous parszhevika Sosnowski white flowers. The stem of the Siberian Hogweed is bristly, the hairs on it are very clearly visible. In the cow parsnip, Sosnowski, the stem is smoother.

How to protect yourself from cowberry Sosnovsky?

Though he is dangerous, he does not attack people himself. It is enough to follow simple safety rules: do not tear with bare hands, do not rub your eyes. If the juice still got on the skin, it should be washed and try not to go out for several days. Remember that ultraviolet penetrates through the clouds. If the burn could not be avoided, it should be treated like an ordinary thermal burn. If the juice gets into your eyes, you should rinse them with plenty of water and contact an ophthalmologist as soon as possible.

It is important to talk about the hogweed to children, to show how it looks, so that they know exactly which plant cannot even be touched, let alone pluck it.

How to fight?

It is difficult to fight. Hogweed is good with us, and so simply he will not give up. You can, of course, annually mow it before the formation of seeds, regularly plow the field. But this must be done everywhere, including on the lands of the dacha settlements, which is almost unreal. Therefore, it is not necessary to count on a centralized fight against hogweed.

If the hogweed grows on your site, you can fight it only in one way - constantly mowing. And do it several times over the summer, so that the plant does not have time to bloom and give fruit. It is necessary to mow with great care so that the juice does not fall on you and people nearby. After mowing it is necessary to destroy the roots, because if we use herbicides for weeding the roots, this will lead to the destruction of all other plants as well. Unfortunately, not yet invented a tool that would destroy only hogweed Sosnovsky.

Appearance

Hogweed looks pretty impressive, and, knowing that it is he, it is impossible not to notice. Depending on the species, it can reach six meters in height, but more often it is still shorter - from half a meter to one and a half meters.

The stem of this plant is usually hollow, ribbed, may be covered with a rare or thick down. Branches appear closer to the top of the plant. The leaves are wide, long and smooth, covered with small fibers.

During the flowering period, the hogweed can even be called beautiful. Umbrellas of small flowers appear on it - white, yellowish or pinkish. In the fall, they turn into neat seed boxes that are easily carried off by the wind - this is how the plant multiplies.

Most members of this genus are biennial., but sometimes there are perennials. Nevertheless, they bloom only once in their lives, after which, as a rule, they die off.

Dangerous species

There are up to seventy species of Hogweed, but not all of them are dangerous. Most are still harmless to humans and even used in the economy. However, dangerous species should be given special attention.. There are only three of them:

  1. Sosnovsky's hogweed is one of the most famous; it is what people usually have in mind when they say hogweed. It reaches a height of three meters and blooms once in a lifetime with white or pink flowers. You can recognize it by a large number of leaves and their density, it is one of the most powerful and impressive representatives of the genus. It happens both two-year and multi-year.
  2. Mantegazzi hogweed is the most poisonous plant of all, reaching six meters in height. It is perennial, its flowers are white in color, and the ripened fruit is green. It was he who most quickly captures new territories, the most common in the Caucasus.
  3. Hogweed wild - a biennial plant with white flowers, whose height is up to two meters. Mostly distributed in the southern regions of the country.

All these species of Hogweed are poisonous plants that pose a threat to humans and animals. In addition, if they grew up in a particular place, they would force out any other cultures from their territory. Therefore, finding them in their summer cottage, it is best to eliminate them immediately, until they spread even wider and did not threaten the crops and local residents.

Safe species

Most of the species of this plant is still safe, and in our country there are only some of them. As a rule, they look less threatening: they have a less stiff stem and leaves that do not grow to such huge sizes. Having met with these varieties, you can safely touch them:

  1. Shaggy - common in the south: in the Crimea, the Caucasus, in Asia Minor. Reaches in height to one and a half meters and blossoms white flowers.
  2. Dissected - it grows predominantly in the forest-steppes and on the banks of rivers of Siberia, it has large white flowers.
  3. Siberian - it can be found almost throughout Russia. It is short, covered with green-yellow flowers, and its fruits look like an egg.

All these species are not only safe, but also eaten and used for medical purposes.

The origin of the name and history of appearance

Nowadays, having heard the name of this plant and how dangerous it is, one may experience bewilderment. In fact, how can so poisonous grass be associated with borsch, if it is dangerous not only to eat it, but also to touch it? However, as history shows, not everything is so simple.

Long since in Russia, the word “borsch” meant a jagged object, and because of the shape of the leaves, this plant was also so named. Of course, the food was not used dangerous species, but only harmless, for example, Siberian hogweed. Его листья отлично подходили для различных овощных блюд, которые тоже со временем стали называть «борщ».

Со временем понятие сузилось и стало обозначать лишь суп со свёклой, в состав которого по-прежнему входили листья этого растения, которое теперь уже переименовали и начали называть «борщевик». Gradually, it was used less and less as food, and the history of the name began to be forgotten.

The Latin name of this genus of plants is Heracleum, which, as it is easy to guess, is derived from the name of the ancient Greek mighty hero Hercules. This name appeared due to a very frightening and impressive appearance, especially when compared with the rest of the umbrella family. It is not only high and powerful, but also enduring: it withstands almost any natural conditions, is able to survive even at sub-zero temperatures and is resistant to many toxic chemicals.

In Russia, it spread with the light hand of Stalin, who learned that in the USA it is widely used as a feed crop. It grows fast, has high endurance - what else is needed for agriculture? Its implementation went at full speed and was continued by Khrushchev and Brezhnev.

However, it turned out that he is not so perfect. The milk of the cows that consumed it became bitter, and soon the reasons for this were discovered - the culture was recognized poisonous. And then perestroika struck, and ceased to cultivate it, as well as track its progress in the wild. Taking advantage of this moment, it has grown so much that it is still not possible to take this process under control, although it was initially feared that it might become a malicious weed. So it happened.

Methods of struggle

Finding out whether poisonous hogweed or not, should immediately destroy this dangerous plant. There are many effective ways to do this and you can choose the most suitable in a particular situation.

If the hogweed occupies a small area, cutting the flowers at the moment when they are just starting to bloom can be called the most effective. The same method is at the same time the most dangerous for a person, since it is very easy to splash juice. Therefore, it is necessary to strictly observe the methods of protection. You need to cut all the umbrellas with flowers or formed fruit. As soon as the seeds ripen, they will begin to be spread by the wind, forming a new generation of weed.

Far less dangerous for humans, although more damaging to the environment can be called the burning of plants with fruits that started ripening. The main thing is not to miss the moment when they were just formed, but not yet turned into full-fledged seeds. Hogweed should be sprayed with flammable liquid, focusing on its umbrellas, and set on fire. It should be remembered that it will emit flammable essential oils, which can also pose a danger to humans.

Another available option is to mow all the shoots every few weeks, preventing them from forming inflorescences and spreading more. It is necessary to begin this process before the flowers have ripened, otherwise it will only contribute to its further spread.

Various herbicides can be used to control. This method is also effective only before flowering, and the treatment must be repeated several times, using far larger doses than indicated in the instructions (double or even triple). Since after the formation of fruits, the hogweed will die off itself - its life cycle will end there - then if the moment is lost, there is no longer any sense to process it. It is enough to carry out the procedure 2 times with a break of two to three weeks.
