Insecticide is one of the important drugs used by gardeners, gardeners and flower growers. Finding one that is effective, has the fewest side effects, and is inexpensive is difficult. But it's quite possible. When selecting a protective agent against parasites, they also take into account the fact that it must destroy not just a dozen pests, but much more.
If we consider the drug Intavir, then it meets all the indicators and requirements put forward by farmers. The product can be used in large and small areas, for fruit, berry and vegetable crops, on all types of soil. The spectrum of action of the insecticide includes more than 5 dozen parasitic insects.
Composition and release form of the drug
The insecticidal drug "Intavir" can be purchased in tablet form. The tablet with the active substance quickly dissolves in liquid. There is a powder form of the drug with similar dissolution ability. The concentration of the active element "Cypermethrin" is 3.75 percent. The main active element is included in the subgroup of pytertoids - analogues of plant insecticidal agents with contact-intestinal effects. When insect pests interact with it, they provoke nervous system disorder, organ spasms, convulsions and death. Natural “Pyrethrin” is included in the composition of extracts of chamomile, tansy stems and green mass of chrysanthemums. The product has a wide spectrum of action and is safe for plants.
"Intavir" is the optimal way to combat insects
Security measures
The drug is a chemical analogue of natural insecticides. Intavir is dangerous for people, so it must be handled with extreme care. Although the insecticide does not cause severe poisoning, it is toxic. If the product gets into the respiratory tract, poisoning may occur, the symptoms of which will be dizziness, diarrhea and vomiting. It is recommended to rinse your mouth with a solution of potassium permanganate and wash thoroughly.
In order not to harm yourself and others, garden processing should be carried out in protective clothing, a mask (medical) or a respirator, rubber gloves and boots. If the treatment is carried out at home or in a greenhouse, the premises must be ventilated after a few hours.
Reviews about the drug
Its use is effective in controlling pests in garden plots.
Ekaterina Semenovna Galtseva, Volgograd:
I treat all plantings with Intavir. Peppers, eggplants, radishes, even roses. It does not get rid of pests forever, but it does deal with fleas, aphids and whiteflies.
Alexander Ivanovich Petrov, Kursk region:
I use it no more than twice a season. Helps better than any traditional methods. I recommend it for processing plums.
However, there is another opinion about this remedy:
How does the product work?
The name of the active ingredient is borrowed from the name of the plant in which its highest concentration was detected - pyrethrum (Dolmatian chamomile). Synthesized artificial analogues, characterized by a stronger paralyzing effect on insect pests. The main effect is a paralyzing effect on various pests of the garden and home after treatment by irrigating the green mass of the plant. The drug has a subtle odor that attracts insects. A thin film is formed on the surface of the treated leafy part of the plants, which does not penetrate into their cells. When insect pests come into contact with the surface of plants coated with the drug, it enters the digestive tract. From there it quickly penetrates all systems of the body, causing inevitable death. The duration of action after a single treatment ranges from 15 days to 1 month.
Pests sensitive to Inta-Vir
The drug "Inta-Vir" is produced by agro, which is well known to Russian summer residents for other products - fertilizers, soils, etc.
According to the statement, it is effective against more than fifty species of pests of cultivated plants. However, insects show different susceptibility to this drug:
- The most sensitive to cypermethrin are leaf-eating pests with a thin chitinous covering: leaf rollers, moths, cutworms, moths, Colorado potato beetle larvae, all types of caterpillars, etc. The substance easily affects them both through contact and intestinal routes.
- Sucking insects with a thin chitinous covering and gnawing insects with a dense shell have average susceptibility: aphids, weevils, whiteflies, pennies, psyllids, flies, flower beetles, adult Colorado potato beetles, etc. “Inta-Vir” acts against soft-bodied suckers only contactally, and against thick-bodied chewers – only intestinally.
- Weak sensitivity is observed in sucking pests with a thick chitinous shell - for example, scale insects. The contact effect of the drug is rather weak, and it cannot penetrate through the dense shell into the insect’s body. At the same time, cypermethrin is not absorbed into plant tissue, so it is difficult to poison scale insects with this substance through the intestines.
In this regard, it is important to note that increasing the dosage of the drug does not increase its effectiveness against insects with low susceptibility. The results of the treatment depend only on whether the solution can enter the pest’s body.
What is Intavir used for?
The product "Intavir" against pests has a wide range of effects on parasitic heteroptera and other insect pests. They use Intavir against spider mites and other pests that parasitize plant organisms:
From scale insects
At the first signs of appearance on floral or decorative foliage crops, indoor flowers, primary treatment is carried out. In cases of relapse, it is advisable to repeat the procedure.
"Intavir" fights ants well
From ants
A special product has been prepared for these pests. To exterminate red (house) and garden ants, make a bait or purchase a ready-made one. Baits are placed in places of migration of ants of all types, near places of mass habitat.
From ticks
To get rid of house ticks, prepare a solution or bait. The solution is used to treat surfaces along the path of insect movement. It is also sprayed on tall grass, where dangerous insects are preparing to attack. When spider mites appear on plants, all their parts and accessories are irrigated with the working solution. After a week or two, repeat spraying is carried out.
From aphids
Treat crops affected by aphid colonies after abundant flowering. It is especially important to treat the back side of the leaves.
From weevil
The pest can be destroyed by treating the plants with a prepared Intavir solution before the flowering period begins. The last spraying procedure can be performed 20-30 days before harvest.
The product is used against aphids
From cockroaches
For cockroaches and vermin, the method of using insecticide is similar to the method of getting rid of ants.
From crickets
Spraying surfaces and tall grasses within the radius of possible insect habitat helps prevent loud night singers.
From bedbugs
Bedbug baits are left in the area where parasites are expected to live and where they are concentrated, along the path of their movement. When a mass infestation occurs on trees, the crowns are thoroughly sprayed.
From whitefly
Crops of interest to this parasite are treated repeatedly. The latter procedure is permissible 25 days before harvesting ripened fruits.
Toxicological properties of the pesticide "Inta-Vir"
The waiting period from the last treatment with Inta-Vir to the removal of fruits is at least 30 days.
When it gets into the soil, Inta-Vir completely degrades, decomposing without any residue into safe compounds. The rate of decomposition depends on the soil structure:
- on clay soils - about 10 weeks;
- on sandy ones - 2-4 weeks.
In rainy weather, Inta-Vir degrades faster, since cypermethrin is easily hydrolyzed. The drug does not exhibit phytotoxicity, and a number of auxiliary substances that are used in its production even serve as a mineral feed for plants.
According to official data, Inta-Vir belongs to the III class of danger to humans. This means that the substance can only be poisoned if it enters the stomach directly.
Hazard class for bees – II. Spraying must be carried out in strict compliance with environmental regulations:
- when the wind speed is less than 3 m/s;
- at an air temperature not higher than +150C;
- at a distance of at least 3 km from the apiary;
- while restricting the flight of bees for 72 hours.
You cannot work with Inta-Vir near water bodies, since cypermethrin is very toxic to fish.
Pros and cons of Intavir
Among the expressed positive qualities are:
- wide range of effects;
- guaranteed elimination of parasitic pests;
- ease of use;
- absence of a sharp unpleasant odor;
- the ability to save the harvest;
- preventing damage to finished agricultural products by worms and slugs;
- preservation of the decorative properties of cultural plantings.
"Intavir" has a wide range of effects
There are also disadvantages that may arise when using an insecticide:
- the ability of insect pests to reduce sensitivity to the toxin;
- has a teratogenic effect;
- toxic to bees and helping insects;
- changes the soil composition, destroying soil bacteria;
- ineffective against larvae and eggs of pests;
- washed away by precipitation and watering;
- long period of waiting for the effect to occur.
Comparison of Inta-Vir with other pyrethroids
The active substance of this insecticide is related to another well-known pyrethroid - deltamethrin, which is the basis of the powerful insecticide "Decis" → how to use Decis against pests + reviews. The difference between them is that the Inta-Vir molecule contains a chlorine ion, while the Decis molecule has bromine in its place.
Bromine ion significantly enhances the contact poisoning effect of Decis. In addition, the deltamethrin molecule itself is much more stable than the chlorine-containing Inta-Vir molecule. It is not so easily hydrolyzed and is not susceptible to the action of the neutralizing enzyme mentioned above.
And yet, Inta-Vir has an important advantage over its more lethal analogue. It is safer for both humans and the environment. In addition, the production of cypermethrin is cheaper, which affects the retail price of the drugs.
Consumption rates for the drug to protect various crops
The current solution for irrigation of crops is prepared according to this principle - 1 table. The drug is kneaded in a plastic container with a glass of liquid until a paste-like mass is obtained, the total amount is added to 1000 ml. Next, the resulting concentrate is diluted with liquid, taking into account the characteristics of the crop affected by pests:
Berry
"Intavir" for strawberries in spring is used in the proportion of 2 tablets. for 2 buckets of liquid. Material consumption 1.5 – 1.8 l. per 1 square meter. A single spray is enough. Treatment of currants in the spring with Intavir is carried out at the rate of one to one and a half liters per bush, twice until the ovary forms. To prepare the solution, take 1 tablet. and 1 bucket of water.
Fruit trees
The crown is irrigated with the prepared dissolved preparation (1 tablet per 1 bucket of liquid). The time for Intavir is when to spray optimally before the color of fruit and berry products changes.
Fruit trees respond well to spraying with Intavir
Vegetables
The last time it is permissible to treat vegetables with Intavir is 3 days before harvesting the finished fruits. Double irrigation of crops is required, both indoors and outdoors.
Indoor flowers
The abundance of pests on crops serves as a signal to treat flower crops with Intavir solution prepared from 2 tables. for 1 bucket of water. The frequency of procedures must be at least three.
Preparation of the solution
To use Intavir effectively, read the instructions. The diluted liquid has a pungent odor. Its action is influenced by the freshness of the solution and adherence to the preparation procedure:
- The mixture is prepared in a well-ventilated area or in the fresh air.
- 1 tablet (crush to quickly prepare the composition) should be dissolved in a small amount of water, then the volume should be increased to 10 liters.
- If the treatment area is small, take half an Intavir tablet and 5 liters of water.
Preparation of Intavir
Instructions for use of insecticide
Following the recommendations for use allows you to get rid of hated parasitic insects in a short time. Main method of application:
- the prepared solution must always be fresh;
- main proportions for preparing the concentrate – 1 table. for 5, 10 l. liquids, depending on the crop;
- Irrigation is carried out not only on the affected part of the plant, but on the entire area;
- observe personal safety measures.
When used for indoor, decorative foliage, and flower crops, use a solution of 2 ml. concentrate diluted in 1000 ml. water.
We treat the bushes with Intavir using a 2 ml solution. concentrated gruel with 2000 ml. liquids. When processing vegetables, prepare a working liquid from 1 ml. concentrate and 1 liter of liquid.
Indoor flowers can also be treated with Intavir solution against pests
Storage conditions
The drug retains its protective properties for 2 years from the date of release. In this case, the temperature should be within -10-+45 degrees.
Opened or damaged packaging is not subject to further storage. The product should be placed away from food and medications, as well as in places inaccessible to children. The prepared solution should be used within 1 day, as later it loses its properties.
You can achieve quick and effective results by strictly following the instructions for use of Intavir. Reviews from flower growers and gardeners only confirm this fact. But you should understand that any disregard of the manufacturer’s recommendations may negatively affect the final result.
First aid
The drug can cause unexpected reactions upon penetration into the gastrointestinal tract and mucous membranes. In these situations it is urgent:
- drink from 5 to 8 tablets. activated carbon;
- rinse the mouth with a pale pink solution of manganese;
- take a mild laxative + one and a half liters of liquid;
- seek qualified help from a medical institution.
If unprotected skin is affected, repeated rinsing with cool, clean water is required.
Reviews about the use of the drug "Inta-Vir"
Many summer residents, who have long been familiar with Inta-Vir, believe that the drug is morally outdated. However, a number of reviews do not confirm this opinion:
“About 7 years ago I gave up Inta-Vir and switched to more modern insecticides. But this year we had to urgently save roses from hordes of aphids, and in the local small store there was nothing except the good old Inta-Vir. To my surprise, he quickly dealt with the insect colonies. I examined the roses after 2 weeks - the aphids did not return” (Oksana, Chelyabinsk).
Preventing the appearance of onion flies
You can avoid insect attacks by applying a number of measures familiar to every gardener and vegetable grower.
- Maintain crop rotation - you cannot plant one crop in one place for many years in a row; onions are rotated every 3-4 years.
- Before sowing, bulbs (at home and in the garden) are treated with either a manganese solution or a purchased fungicide. The same applies to material left for winter storage.
- For domestic bulbous plants, there is a rule for disinfecting the soil; for a vegetable garden, it is mandatory to remove all plant debris and deep digging. Insect larvae quietly overwinter in bark or forgotten bulbs; eggs can also be in a non-sterile substrate.
- In the beds, repellent plants will help prevent the appearance of pests - wormwood, marigolds planted in the rows. The smell of repellents repels the onion fly, so by avoiding visiting such plantings, it will not lay offspring.
- A good protective tandem is carrots and onions planted side by side. Experienced gardeners have noticed that the carrot fly cannot stand the smell of onions, and the onion fly does not like the aroma of carrots. Crops need to be planted in rows, since they have different watering frequencies.
- Pine needle mulch, placed on the beds immediately after the first shoots appear, effectively repels insects and prevents them from laying offspring.
Did you know? The fly flaps its wings at a speed of up to 200 times per second, and the buzzing sound during flight is produced by a pair of elongated processes located behind the wings.
Getting rid of insects in the garden and in the apartment is not so difficult. But it is still better to prevent its occurrence than to treat affected plants.
Precautionary measures
Opened packaging cannot be stored. If the product is accidentally spilled, it must be collected in a bag and covered with sand, the bag should be packed and thrown into a container with household waste.
And although the manufacturer believes that the drug does not have a toxic effect on humans, you should wear protective glasses and gloves when working with Inta-Vir solutions. After work, the face and hands should be thoroughly washed with soap and running water, and the clothes in which the treatment was carried out should be changed.
Under no circumstances is it recommended to use containers intended for food purposes to prepare working solutions.
In case of accidental ingestion of the product, the mouth should be thoroughly rinsed with a weak solution of potassium permanganate and drink 2-3 tablets of activated carbon.

Onion fly - description
What does an onion fly look like? This flying insect is light gray in color, about 1 cm long. Males differ from females only in the presence of a dark stripe on the abdomen. Female flies are fertile: during their lifetime they are capable of laying up to 60 white eggs with a longitudinal stripe up to 1 mm long.
Onion fly
The summer of onion flies begins early - in April. Pests lay eggs on the leaves of onion crops or on areas of bulbs protruding from the ground. After 5-8 days, an onion fly larva emerges from the egg, which immediately penetrates into the onion pulp and feeds on it, and after 2-3 weeks the larva becomes an adult insect. In one season, onion beds can be attacked by two or three generations of onion flies.
As a result of the vital activity of the larvae, the bulb heads soften and become unsuitable for food. If flies are not eliminated before they lay eggs, a significant portion of the crop can be lost. The presence of an onion fly in a garden bed can be determined by the following signs:
- plant growth and development slow down;
- onion feathers break and turn yellow prematurely;
- an unpleasant odor emanates from the plant;
- the bulbs become soft and rot;
- under the upper scales of the bulb you can see scurrying worms;
- plants rot or dry out completely.
