Repellents what is it

Hello! When I was just starting life on my own site, the problem of various annoying insects almost always occupied my first place.

She especially suffered from nasty mosquitoes and small midges. There was not even an understanding of how best to resist them.

But over time, the situation has improved for the better. Now I have a tool to solve this problem. Want to know more about repellents - what is it and how can they help you in the fight against annoying insects? The article below has all the answers for you.

How can repellents help us?

Summer will come very soon, which means that all sorts of insects will begin to attack us. Some of them bite, which is very, very unpleasant. And how to protect yourself from these pests? Fortunately, today in any store you can find special tools - repellents.

Important!
What are repellents? This is a common name for all means of protection against various insects: from mosquitoes, from ticks, bugs, midges, from moths and so on. Such funds are not used to exterminate pests, but only to scare them away, so that environmentalists can be calm.

The methods of exposure to such agents may be different. For example, some act on the olfactory organs and repel them using an odor unacceptable to insects. Others affect the auditory organs and mimic various frightening sounds accessible only to insects. And others act directly upon contact.

How to choose a repellent? When choosing, you should pay attention to several important points. We touch on each of them.

From whom are they protecting?

Remedies can protect against different types of insects. For example, some are scary only for mosquitoes, others protect against ticks, some affect midges.

There are also combined repellents that provide protection from several types of insects at once.

You can also find almost universal means, they will scare away any "bastard" who dares to fly up to you and decide to bite.

We study the composition

If you decide to purchase repellent, then by all means study its composition. It should be studied especially carefully if you want to treat the child with a remedy. We should also say that far from all repellents are allowed for use in childhood.

On the packaging you will find information about this. For babies up to a year, practically nothing can be done, since you can find repellents that are allowed only from 1 year old.

Advice!
Also on sale are funds that can be used from 3 years. Conventional adult repellents are most often suitable for children over 6 years old, but better clarify this by studying the instructions for use.

So what can be part of repellents?

Diethyl phthalate (abbreviated DETA). Such a component is used most often. It is cheap and very effective. But there is one big pitfall. Such a substance is toxic and can be hazardous to health. For children, such remedies are definitely not suitable, but it is more worthwhile to be an adult.

The opinions of doctors and scientists on this subject are somewhat divergent, but, for example, in the USA and European countries there is an indication on such products that they can be applied exclusively to clothing, and repellents of this group are contraindicated for children under 6 years of age.

For pregnant women, DETA is also dangerous, as it can cause a miscarriage or pathology of the fetus. If you decide to purchase such a tool, then remember the rules for its use. Apply it in small amounts and only on clothing, but not on the skin.

Alcohol. It is used as a basis (not always). In fact, such a component is harmless, but it can irritate excessively sensitive skin.

Pyrethroids. Such substances also effectively protect against insects. But they are dangerous only for insects, for humans they are harmless.

Essential oils. In general, natural ingredients are preferable, as they are less harmful than synthetic or chemical ones. Other auxiliary components are also used.

Degree of protection

How good and how long will the remedy protect? It depends on the concentration of the active substance. So, if it is 30-40%, then you can be calm for as long as 5 hours after application.

At a concentration of about 25%, forget about insects for three hours. If the concentration is only 10%, then the product will protect only a couple of hours, not longer.

Release Forms

What are the repellents by release form? We list them.

Attention!
Creams and ointments. Such products are applied only to the skin. This is very convenient, because in hot weather many people wear open clothes, and the whole body is prone to bites. But there are also some disadvantages.

Firstly, many creams are oily and can leave marks on clothes, as well as cause discomfort after application. Secondly, some insects can even bite through clothing.

Lotion also applied to the skin and faster and better absorbed than creams.

The pencils. This is not very convenient, since the product is applied for a long time.

Spray. It is also applied mainly to the skin; when applied to clothing, traces may remain.

Spray can. Such a tool is convenient to spray, it can be applied to clothing, hair, surrounding objects. It is very practical and convenient.

Spiral. This option is optimal for gatherings on the street in a large company. The spiral is set on fire and smolders, the resulting odor repels insects. But such repellents smoke and smell bad.

Fumigators. The fumigator is a kind of heating device into which a plate with an active substance is inserted. When heated, the substance evaporates and spreads throughout the room. Such repellents can only be used in houses and apartments.

Ultrasonic repellent. This tool is safe for people, but it repels mosquitoes perfectly. It makes sounds similar to the sound of a male reporting a danger. Only females bite, and when they hear the alarm, they will certainly retreat.

Napkinsimpregnated with liquid. They can wipe the body.

Quality

Inspect the packaging to evaluate quality. It should have information on certification and compliance with quality standards.

Important!
If it is marked “Approved by the Ministry of Health”, then it is better to buy just such a repellent.

In addition, you should give preference to popular means that have an impeccable reputation and have proven their best.

Where can I buy? How much is?

Buying repellents is best in pharmacies or in large stores. In stalls and basement pavilions, as well as in markets, fakes or low-quality goods with expired shelf life can be sold.

The price of such funds can vary from 50-70 rubles to 300-500 or more. It all depends on the composition, manufacturer and type of repellent.

How to use?

A few basic rules:

  • To avoid an undesirable reaction, try the product on a small area of ​​the skin (or for a short time in the case of fumigators).
  • Do not rub creams into the skin, apply them to the surface.
  • Avoid the eyes, mouth, and nose.
  • Do not apply on damaged skin.
  • It is better not to handle the child’s hands, because he can pull them in his mouth.
  • Do not apply excessive amounts and do not repeat treatments too often, as this may result in poisoning.
  • Use repellents only in case of a real threat, that is, in direct contact with insects, and not "just in case".
  • On clothes, the repellent continues to be active for one to two weeks (when wet, activity decreases, when washing ends).
  • After arriving home, be sure to wash the product with soap and water; it should not remain on the skin for a long time.

Repellents

Repellents are repellents for insects and ticks. Repellents are used in cases where it is impossible for some reason to destroy insects, especially in open nature (forest, field, etc.).

According to the mechanism of action, three groups of repellents are distinguished: 1) preventing the insect from choosing the object of attack, changing the natural smell of the skin; 2) preventing the insect from landing on the skin and piercing it (a deterrent effect), acting on the olfactory organs of insects) providing mechanical protection to the skin (petroleum jelly, etc.).

Repellents belonging to the second group of compounds are widely used in practice.

These include:

  • benzimine (hexamide) - benzoylhexamethyleneimine (colorless or slightly yellowish liquid),
  • dibutyl phthalate - phthalic acid dibutyl ether (clear, colorless oily liquid),
  • dimethyl phthalate - phthalic acid dimethyl ether (clear, colorless liquid),
  • diethyltoluamide, synonym for "DETA" (light yellow oily liquid),
  • carboxide - dihexamethylene carbamide (in its pure form a clear or slightly yellowish liquid),
  • cusol-acetyl 1,2,3,4-tetrahydroquinoline (yellow syrupy liquid),
  • repellin alfa is a mixture of repellents: 48% dimethyl phthalate, 50% benzylpiperidine and 2% ethyl cellulose (yellow oily syrupy liquid).

Repellents are used in pure form, in solutions, ointments, creams, lotions, pastes. For the preparation of solutions use alcohol, acetone, freon. In the manufacture of the emulsion used glycerin, petroleum jelly, etc.

When using repellents, the consumption of a pure preparation is calculated on average at the rate of 40 ml per 1 m2 of clothing or 32 mg per 100 g of tissue. Outerwear (shirts, trousers, sweaters, skirts) are treated with rubbing the drug with your palms.

Advice!
300-400 ml are applied to a men's suit; 50 ml are spent on headgear processing. Clothing can also be treated by spraying (spraying) a clean or diluted 2-4 times preparation. Some repellents dissolve plastics (buttons, etc.).

Repellents are used both to protect an individual person and collectives (lumberjacks, construction workers, military units in camps, etc.) in places abounding with vultures (mosquitoes, midges, horseflies and mosquitoes) or ticks.

With collective protection, tents (bottom, entrance, etc.), vegetation (shrubs) around the camp are treated.

Cellulose jelly repellents are used to impregnate protective nets. Find the use of Pavlovsky mesh (from the fishing net) 50 X 70 cm in size, which cover the head. In order to fix the repellent on the grid, cellulose acetate jelly is used.

To protect a person, special underwear can also be used, which mosquitoes and other insects cannot pierce. Designed clothes (nets worn under a shirt) of threads, the thickness of which is greater than the length of the proboscis of a mosquito.

Repellents are applied to exposed parts of the body just before going to places full of gnats and ticks. To lubricate the face, body, hands (to the elbow), 1.5-2 g (15-20 drops) of the drug are required; he is taken in the palm of his hand, then smeared on the skin. When rubbing on the face, they protect the eyes from getting the drug. Repellents cause a burning of freshly shaved skin.

When irrigating skin and clothing, aerosol containers containing repellents are used. Repellents are not used against fleas, cockroaches, flies, bugs, ants and moths.

How to choose a remedy for ticks and mosquitoes

Repellents are chemicals that repel insects. They act in different ways. Some scare away ticks, the second - mosquitoes, and the third - and those and others at the same time. It is better to buy combination drugs.

Attention!
They come in the form of aerosols, emulsions, lotions, creams, gels and napkins impregnated with a special substance.

But the efficiency is practically independent of the form of release. The easiest way to find aerosols, creams and gels is on sale.

What are they made of?

The composition of repellents can include various substances of both chemical and natural origin: essential oils, alcohols, pyrethroids, diethyl phthalate (DETA) and others. The most safe and effective repellents made on the basis of pyrethroids.

They have a toxic effect on insects, for humans it is completely harmless. Nevertheless, most often repellents are made on the basis of DETA - they occupy 60% of the global market for blood-sucking insect repellents.

Despite the fact that diethyl phthalate is a highly hazardous toxic substance, it is most often used in repellents - it is effective and relatively cheap.

Many manufacturers replace the well-known abbreviation DETA with the lesser known full name "diethyltoluamide." Safer, but no less effective means are much more expensive, and there are few of them on the Russian market.

What is DETA dangerous?

Among Russian doctors, there is no unequivocal opinion about the danger of DETA - some say that the concentration of DETA in repellents is harmless, while others advise using the funds carefully.

In some countries, for example, in the USA, England and Australia, DETA products are sold indicating that they are toxic and should only be applied to clothing. And children under six years of age are generally forbidden to use them. That is, in fact, repellents are conditionally safe only when used correctly.

Important!
However, in Russia there are no such indications. Limitations of use - only for pregnant women (DETA can cause severe developmental disorders in the fetus and even provoke a miscarriage) and for children under three years of age. All others apply the drug not only to clothing, but also to the skin.

And through it, a harmful substance, once in the body, can cause poisoning or allergies. Moreover, DETA is able to affect nerve tissue.

The most dangerous place for applying DETA funds is the face: when draining from sweat, funds can get on the mucous membranes of the mouth and nose, in the eyes. From there, to the blood, which can cause severe poisoning. Lubrication of the hands is also not harmless: the drug can enter the body with food.

Signs of DETA Poisoning

If headaches, drowsiness, irritability, coughing, skin irritation appeared after the use of repellents, it is likely that this is DETA poisoning. For many, it is easy and the symptoms are blurred. Therefore, the majority do not even realize that repellents are to blame for their poor health.

In severe poisoning, breathing may be impaired, gait may change, disorientation, toxic encephalopathy and even paralysis of the musculoskeletal system, respiratory paralysis and coma may occur.

Do not be alarmed, it is difficult to get such severe poisoning of DEET from repellents. But given that 17% of diethyltoluamide is absorbed from the surface of the skin and enters the bloodstream, you should not abuse these funds.

Allergy to mosquito repellent

Allergies to repellents occur infrequently. With it, irritation appears on the skin, a dry cough may begin, or nasal congestion may occur.

However, allergic reactions to repellents are more likely in people already suffering from any type of allergy. In this case, it is worth choosing repellents marked "hypoallergenic", but they do not guarantee complete safety.

Advice!
In hot weather, it is better not to use repellents at all - at temperatures above 25 degrees they can behave unpredictably and provoke allergies or poisoning. By the way, at a temperature of plus 28 degrees mosquitoes are generally harmless, they hardly survive, they are not up to bloodletting.

Modern repellents should not give an allergic reaction even with prolonged contact with the skin. But if protection from insects is no longer required, the product should be washed off the skin as soon as possible.

How to use

If it is possible not to use repellents, it is better not to do this. But if contact with insects cannot be avoided, repellents should be used when there is a risk of being bitten.

It is best to apply the product on clothes - it retains its properties much longer than on the skin: up to two weeks with daily wear. If the clothes are wet, then the effect of the drug decreases, and after washing disappears altogether.

If the product is nevertheless applied to exposed skin, do not forget that pustular rashes, irritations, dermatitis, minor skin injuries (abrasions, scratches) can lead to an unpredictable reaction. Therefore, repellents must be applied to intact skin.

You can not use repellents constantly for a long time and apply them more often than indicated in the instructions.

For children, it is better to use herbal products: either special children's repellents made from natural ingredients, or hand-made products. For example, you can use clove oil or vanilla.

It is believed that aerosols are best applied to hair and clothing, and creams, gels, lotions and napkins - to use for exposed skin. To minimize the likelihood of an allergic reaction to repellents, when applied, they do not need to be rubbed into the skin - just lubricate it.

Attention!
For a single treatment of exposed skin: neck, arms, face, legs, 5–10 ml of lotion or 3-5 g of cream are required.

To process clothes, nets, curtains, tents, 20-30 percent water emulsions of repellents or aerosols are used.

If an aerosol is applied to the skin, the repellent stream is sent to the surface of the body for ten seconds until completely moistened.

How to choose repellents

All fumigants and repellents are made of toxic substances, so they must be registered with the Ministry of Health and receive a certificate. Means that do not have a certificate are dangerous not only for mosquitoes, but also for people. Foreign products are usually very toxic.

They contain about 50% of the active substance, and the Ministry of Health does not issue them a certificate. However, they still hit the market. On the shelves you can sometimes see 100% of the product. Therefore, always read the label carefully.

The concentration of toxic substances is the second indicator after the certificate, which is worth paying attention to. The toxicity and duration of repellent action depend on it. The higher the concentration, the more toxic the agent and the longer it works.

The longest ones are repellents of the highest category.They contain 30–40% of the active substance. They last up to five hours. In the preparations of the second category, the concentration of the toxicant is 20–25%; they protect against insects for up to 3 hours.

The shortest ones contain no more than 10% of deterrents and last no more than 2 hours. But even pregnant and young children can use them, which should be written on the label and confirmed by a picture.

It is best to purchase protective equipment in a pharmacy, and not in stores, and especially not in stalls. The fact is that all repellents must be stored at a temperature not exceeding 25 degrees. If the temperature regime is not observed, then the drug will lose effectiveness at best, and at worst it will behave unpredictably.

Important!
It doesn’t matter which brand you will use. But if unknown manufacturers do not inspire confidence, rely on long-established ones on the market and managed to prove themselves.

When buying, be sure to pay attention to the expiration date. It is best to purchase protective equipment immediately before use.

For children it is better to buy special children's repellents. They are made on the basis of natural raw materials - essential oils and contain a lower concentration of active substances.

Repellent plants - helpers in garden pest control

With the advent of heat, nature comes to life, and with it numerous insects wake up. Repellent is the best skin protection against painful bites and irritations.

Repellent is a general definition of chemicals and insect repellents.

Application

Depending on the purpose, all repellents can be conditionally divided into several groups:

  • Intimidating agents. They are characterized by a very pungent odor that prevents the insect from even approaching the skin.
  • Masking agents are designed to eliminate the smell of the human body, so the insect loses interest and is looking for another, more attractive object for itself.
  • Fumigators - means, which include an element that affects the nervous system of the insect. Using a fumigant can be dangerous for a person prone to allergic reactions.
  • Ointment and cream are external agents. Of the advantages it should be noted accessibility, ease of use. Of the shortcomings - a greasy cream or ointment stain clothes, and also cause some discomfort after application.
  • Pencil. The compact size of this tool makes it as convenient as possible to use (the tube can always be put in a purse).
  • Spray - repellent is quickly applied to large areas of the body, clothing, hair.
  • A spiral is an excellent tool for repelling insects on the street. When ignited, the spiral begins to give off a very pungent, unpleasant odor.
  • Fumigators - a special device in which a plate is inserted, impregnated with a substance that repels insects. When heated, the fumigator begins to emit fumes that are barely perceptible to humans, but killing for insects.
  • Ultrasonic repellent - a device that makes certain sounds that resemble the squeak of an insect. For a female mosquito (it is she who bites a person), such a sound is a danger signal, having heard that she is retiring from the room.

Terms of use

Before using the protective product, test its effect on a small area of ​​the skin (or for a short time, if it is a fumigator). Such simple steps will help avoid possible allergic reactions.

Creams, lotions and ointments are applied in a thin layer on the skin. You can not rub such repellents.

It is not necessary to apply a protective preparation to the skin in the area of ​​the eyes, nose and mouth.
Do not treat damaged areas of the body.

Use insect protection only if necessary. Frequent skin, clothing, or room treatments can cause poisoning.

Contraindications

Refrain from using repellents in the following cases:

  • During pregnancy and breastfeeding;
  • the age of the child is up to three years;
  • open wounds, purulent inflammation;
  • an allergic reaction to any of the components of an insect repellent;
  • viral diseases in the acute phase of development.

Composition

  1. Essential oils (synthetic or natural).
  2. Pyrethroids are substances that protect against insects.
  3. Alcohol (not always used).
  4. Diethyl phthalate is a special organic compound with a repellent effect.
  5. Auxiliary elements.

Benefits of using

  • Repellents (regardless of the form of release) help to forget about midges, mosquitoes and other insects for at least 4-5 hours.
  • Safety of use. The main active ingredients of the protective drug do not have a negative impact on the environment and human health.
  • Affordable cost of funds.
  • Ease of use.
  • Low consumption of funds.
  • Lack of smell.

Plant repellents - classification

  1. Flower repellents - plants that not only create beauty in the infield, but also repel insects - pests. Most often, flower repellents are planted in the garden, next to vegetable crops.
  2. Garden repellents - plants that produce a very large number of phytoncides, which repel insects and damage the future crop.
  3. Wild insecticides - plants that not only destroy insects, but also have a detrimental effect on human health.

Properties and action

Repellent plants will help rid the garden of pests. Experts recommend that before planting, pay attention and collect information about what effect a particular repellent plant has.

  • Marigolds, marigolds and chicory scare away round garden worms.
  • Garlic will preserve currant bushes or beds with a strawberry from a tick.
  • Elderberry, tansy and bitter wormwood will preserve the harvest of apples and plums from the voracious stalk.
  • Mint, nasturtium and melissa are depressing on whiteflies.
  • The proximity of tomatoes, wormwood or sage will help to save the cabbage leaf from eating the whites.
  • Planting ants from the garden will help planting bushes of mint, lavender, wormwood. Carrot fly does not tolerate the aromas of tobacco, rosemary, onion.

Useful Tips

It is better to plant repellent plants between the rows of the garden, small islands. So they will not burden the main garden and garden crops. It is important to understand that repellents do not destroy plants, they only repel pests. To completely get rid of insects will help spraying, prepared on the basis of herbs - repellents.

Advice!
It is also necessary to remember the list of plants that maintain the natural balance of beneficial insects and pests. These include: sage, fennel, caraway seeds, calendula, thyme, lavender, dill.

No need to endure annoying midges and biting mosquitoes. Having carefully studied the information about the types of repellents and their beneficial properties, you can always choose the ideal option for yourself, ensuring a quiet life without insects.

Repellent plants: what is it and how to use them on the site

There are a lot of pest protection methods. The easiest and most affordable is the fight with the help of chemicals that give almost 100% result, but excessive use of chemistry in the cultivation of vegetables and other edible crops is not acceptable, because in the end it all turns out in the human body, causing allergic reactions coupled with poisoning.

And the repeated use of a “successful” drug is generally unacceptable - it causes resistance of the pest.

Biological products created on the basis of effective microorganisms - fungal and bacterial, are relatively natural and absolutely safe for humans, but their successful use entirely depends on the weather conditions, as well as on the correct dilution of the solution.

The golden mean in protecting against pests can be called natural insecticides, which do not carry any harm to crops and humans, but have a frightening and destructive effect on harmful insects, and some of them even decorate the site.

To be precise, unlike chemical insecticides, repellent plants are not intended to be destroyed, but to a greater extent to repel insects.

But among them there are also potentially dangerous plants that are poisonous not only for arthropods. In order to properly and effectively use repellent plants in the garden, it is worthwhile to dwell on their breeding and cultivation in detail.

Repellent plant groups: properties and action

To begin, we will divide repellent plants into groups, according to the areas of influence:

Flower repellents. These plants are not only repellent for pests, but also a decorating element of the site. These include - sage, marigolds, calendula, chrysanthemum, petunia, nasturtium.

Attention!
They are planted next to vegetables, made from them infusions, which are also effectively used.

Repellents of garden crops. These are the most common repellents, as they are also planted to harvest. These include garlic, onions, mustard, cumin, dill, parsley, as well as potatoes and tomatoes.

These cultures secrete a large number of volatile, which have a deterrent effect on insects. Broths are also successfully prepared from them.

Wild insecticides. This group is controversial, because in addition to the positive qualities of extermination (namely extermination) of pests, some of the wild-growing insecticides are frankly poisonous, which means that they can negatively affect human health.

Useful natural insecticides that do no harm to humans or beneficial insects are: wormwood, bird cherry, elderberry, tansy, tobacco, euphorbia, yarrow, burdock, and mustard.

But the wild poisonous insecticides, which, in order to avoid unpleasant poisoning situations, should not be planted on the site, include: dope ordinary, black belena, Caucasian chamomile, celandine, cow parsnip, aconite, etc.

How to make a competent crop rotation using repellent plants

Grow and plant repellent plants in your garden in such a way that they bring benefits. That is, it is necessary to properly organize crop rotation so that the proximity of cultures and repellents is beneficial, not harmful. After all, there are situations when their neighborhood is negative for a culture and depresses it (allelopathy).

Keep in mind the following “good neighborliness”:

  • Beans, peas, horseradish, beans and coriander are planted next to potatoes (preferably in the aisle). They will save the famous Colorado potato beetle, aphids and some other pests that "love" this culture;
  • Mustard should be planted next to peas;
  • Celery is planted next to cabbage - it is guaranteed to drive butterflies away from it;
  • Marigolds and marigolds can be planted around many crops (strawberries, gladioli, cabbage, etc.), because they repel parasitic species of nematodes that infect plants;
  • Parsley is a good protector against slugs. In addition, along with dill and fennel, it attracts entomophages, which are enemies of phytophages;
  • A good tandem is carrots and sage, tomato and basil;
  • It is useful to plant wormwood and tansy near berry bushes - their strong smell drives away many pests that not only feed on fertile crops, but also tend to lay their eggs on them.

Repellents correctly planted in this way repel and drive away pests, but do not destroy them. For destruction should be sprayed with infusions prepared with them.

So, for example, decoctions of mint, basil and tansy are suitable for all crops of crops that have already been affected by pests, they can be used all the time, except for the period of flowering.

Important!
You can also take note of the category of repellents that maintain a balance between useful and harmful insects in the garden. These are sage, fennel, caraway seeds, calendula, sweet clover, thyme, lavender, dill, etc.

Let us recall the technology of planting useful plants for the garden and the vegetable garden - they are planted either in the aisle of vegetable crops, or directly in a row, directly between the plants ("Melange Garden" B. A. Bublik). A sufficient indicator is 2-3 plants per 1 square meter.

How to properly collect and procure natural insecticides

In order for the processing of crops using infusions from insecticidal plants to be effective and efficient, it is necessary to observe the time of their collection, the methods of preparation and preparation.

As for the collection time, not all season the insecticide plants are used to prepare infusions, there are such intervals when they are useless for this purpose.

This is due to the concentration of essential (toxic) substances in them, which in some periods is minimal and absolutely safe for harmful insects.

Collect insecticides for the preparation of infusion, should be in two periods:

  1. From the appearance of 3 leaves to the flowering period.
  2. After seed ripening before winter.
  3. Infusions can also be prepared from the earthly part of insecticides - bulbs and rhizomes, but only at the end of the season, when enough substances necessary for pest control have accumulated in them.

Plants are harvested in dry, sunny weather, before lunch, or after 4 o’clock in the evening. The use of plants is carried out in several directions.

Working solutions

In the preparation, only fresh, freshly plucked insecticide plants are used, which they collect, prepare the infusion, and immediately use it. It is important to remember that such solutions are not subject to storage. In addition, spraying with such infusions should be used regularly, because they are quickly washed off by rains.

Advice!
And one more thing: only extremely healthy insecticidal plants should be used for infusions, otherwise you can not expect any protection from pests.

In a fresh, but already crushed form, plants can also be applied to the soil when planting a plant (chrysanthemum leaves, hot pepper, celandine) or sprinkle the soil after planting (tobacco leaves, tansy).

Infusions using dry, pre-harvested plants

Along with fresh insecticides, their dry version is also used, for which they are pre-harvested. The blanks are also convenient in that, since spraying must be carried out frequently, a large amount of material is required. Drying is carried out in several ways:

  • Drying in the shade, packing in cloth bags or nets;
  • Drying in brooms, wrappers, in the attic.

In any case, storage should be carried out in a dry, well-ventilated area. Also, dry material can be crushed and then applied to the soil during planting.

Powders based on pyrethrum containing a component such as pyrethrin paralyzing the muscle of pests are very effective in dry form. But if the concentration of feverfew is insufficient, then the paralysis will pass and the insect will remain alive.

All types of chamomile can be attributed to feverfews, therefore, its preparation should be given special attention. The chamomile is dried, and then the inflorescences are ground into powder - the finer, the more effective the solution prepared from it.

The recipe for the solution: 8 liters of warm water, 50 grams of powder, be sure to add an adhesive. It is necessary to insist 4 hours, and plants should be sprayed only in cool weather.

Infusions using pre-prepared concentrate

It is made in the fall - a steep infusion is brewed with boiling water, then the container is hermetically sealed and left for the winter, during which the infusion turns into a liquid concentrate. Then this concentrate is used against the pest, previously diluting it, approximately 1/10.

So, for example, you can prepare the leaves of nuts, after they fly around, the tops of tomatoes and potatoes. It is important to remember that the concentrate is poisonous enough, and its dilution is necessary, and the necessary proportions are studied empirically, trying to start with 1-2 plants.

How to properly prepare infusions and solutions of natural insecticides for spraying crops from pests

To improve the technical qualities of the working solution, when preparing it, it is necessary to use the so-called “adhesives” - components that help liquids stay on the leaves longer, counteracting pests, and not just drain into the ground.

As household adhesives, ordinary laundry soap is best suited, which does no harm to humans, animals and plants. It is rubbed on a grater and introduced into the finished solution, stirring until completely dissolved. When spraying, soapy liquid lingers on the leaves.

Attention!
Also, liquid for washing dishes is suitable as additives in the working solution, but it is contraindicated to use any powder (especially with the content of bleaching particles) - this can adversely affect crops, and possibly human health.

One of the effective and fairly new adhesives are surfactants (surfactants). These include adhesives BIO, OP-10, OP-7, liposam, EPAA-10.

By adding them to an insecticidal solution, a higher-quality adhesion of the infusion to the leaves of the culture is obtained, as well as a slower evaporation of moisture from the leaf. In addition, the solution with the addition of surfactants can be stored in the refrigerator, preserving its "useful" properties for several weeks.

Natural adhesives can also be: Green soap, egg white, decoction of soap root (soap dish medicinal, swing paniculata).

The treatment of plants with working solutions occurs, as a rule, during the whole season, the only exception is the flowering period, when the plants do not need to be disturbed. Before flowering, treatment should be carried out once a week, after flowering, spraying 2 times a month will be enough.

The preparation of infusions against pests can occur in various ways:

Cold way. Universally, about 10 g of necessarily ground ground parts of plants are taken per 10 liters of water. It is best to use several types of natural insecticides at once, mixing them in certain proportions in order to cover a wider range of pests.

For example, such a mixture of herbs is effective: 0.5 yarrow, 0.25 each - dandelion, tansy, euphorbia, nettle. Insist such a solution for a week, then filter. It turns out the concentrate. It is diluted with water in a ratio of 1/10 or 2/10.

Options for infusions with repellent plants:

  • Nettle infusion. Effectively removes aphids from the garden.
  • Infusion of fresh burdock leaves. Effective when spraying cabbage - helps from invasion of moths and cabbage. Such a culture solution must be sprayed every 3 days for 3 weeks.
  • Horse sorrel infusion. Here, slightly different proportions - an average of 300 grams of crushed material is taken per 10 liters of water. Insist only 3-5 hours, then filter and carry out the treatment. It must be carried out several times, with an interval of 3 days.
  • Infusion of buttercup creeping. Bucket is filled on ⅓ with chopped grass and insist 1 hour. After using the first portion, the same cut can again be filled with water and repeat spraying in the morning. Effective against raspberry weevil.

Hot way. The solution is prepared in this way according to the following scheme: about 400 grams of fresh, ground insecticide plants, poured with 10 liters of hot water.

Important!
The infusion time can be from 4 to 24 hours. Alternatively, use the boiling solution under the lid for half an hour.Then, when the solution has finally cooled down, filtering is carried out, and several times using large and small sieves.

A hot solution is dangerous because it can leave a burn on the leaves of plants. It depends on the insecticide itself and its concentrate. Therefore, spraying should not be carried out immediately on all plantings, the infusion should be tested on several single plants, and if everything is normal with them in a day, then you can safely carry out further processing.

If, however, things are not going smoothly with the plant (for example, it “got sad”, lowered the leaves), then the concentration of the solution is reduced by adding a few liters of clean water to it.

Instead of fresh insecticides, powder made from dry material can also be used. In this case, the amount of insecticide used in the solution should be reduced by half.

For example, from rodents, a hot solution based on celandine is effective. This infusion is boiled over low heat.

Spraying with such an infusion is carried out several times, after 5 days. Just remember that celandine still contains poison, and you should work with it carefully.

Alternative pest solutions from natural insecticides

In addition to the usual working solutions discussed above, they also use solutions prepared with other natural insecticides, one of which is Neem oil.

Nima oil is a bio-insecticide that is made from an Indian tulip tree and is a powerful destroyer of many types of pests - the figure reaches 400.

Advice!
Solutions using Neem oil successfully fight with whiteflies, and with caterpillars, and with a scale shield, and with many others. Oil is absolutely safe for humans.

Recipes for preparing a solution using Neem oil:

  • 30 ml of oil and 30 ml of “adhesive” are diluted in 10 l of infusion from any herbs.
  • 50 ml of oil are diluted in 8 l of slightly warmed water, a few drops of rosemary and lavender, and an “adhesive” are added there.

When spraying plants with such solutions, the following principles should be followed:

  • The solution is constantly shaken when spraying, not allowing it to separate into water and oil;
  • Spraying should be carried out from a fine spray;
  • Spraying is carried out every week for a month, and only before flowering.

You can buy oil and its analogues in pharmacies, specialized stores.

And although the protective effect of natural insecticides is not as pronounced as that of pesticides, 2-3-time sprayings confidently restrain the number of pests. And in the opinion of Pavel Trannua, cultivated plants also absorb protective substances if they are used with dew.

We hope that such repellent plants are now clear to you, and you can use them both to scare away and to destroy pests that have appeared.
