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
Properties of the drug
The active component of Intavir, when ingested, has a paralyzing effect on the body. Pests are affected by nerve endings, spasms and convulsions appear, which lead to death. The product is not dangerous for plants, but for humans, animals, and beneficial insects (bees, wasps, bumblebees), the toxicity of the composition is high.
Properties of Intavir
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.
Insecticide (pesticide) Inta-vir against plant pests
Important restrictions when working with the drug
The most important condition is that the drug Inta-vir cannot be used on flowering plants, this can lead to mass death of bees. Activities for processing fruit, berry and vegetable crops must be stopped 3-4 weeks before harvesting the products (in the instructions this is stated as the “waiting period”). Instead, during the flowering periods and shortly before the ripening of the crop (if urgently needed), the biological agents Fitoverm and Akarin are used (can cope with any aphids, caterpillars, young larvae, various mites), as well as Bitoxibacillin and Lepidocid (from some varieties of aphids and caterpillars).
The substance only affects insects; there is no point in using the drug against fungal, bacterial, or viral diseases. Preventive early spring spraying of the entire garden with Inta-Vir, when the pests are still dormant, is also ineffective; This is unnecessary harm to the environment and a waste of effort, time and money for the farmer.
If there is an unused solution of a chemical left, do not pour it into bodies of water or near them: this is harmful to fish and other aquatic life. The liquid should be buried in a hole under a layer of soil: in light soil the compound is destroyed in a month, and in heavy soil - in two.
Operating principle of Inta-vir
For centuries, dried flowers of a plant called “Dalmatian chamomile” (pyrethrum) have been used against harmful insects. It was only in the second half of the twentieth century that chemists synthesized similar artificial substances called pyrethroids. They have a hundreds of times stronger effect on insects. In 1971, scientists obtained the second generation pyrethroid cypermethrin. It is this insecticide (pesticide) that forms the basis of a special tablet known as Inta-vir.
The tablet of the drug is diluted in water, and a cloudy solution of cypermethrin with a slight characteristic odor is formed. When sprayed, the substance settles in a thin layer on the plants without penetrating into the tissues. Insects come into contact with the treated surface and ingest particles of the chemical with plant food. The poison quickly destroys their nervous system and leads to death. However, this insecticide does not kill insect eggs.
Cypermethrin coating can have a detrimental effect on pests for two weeks (up to a month).
There is evidence that repeated use of the drug over several years can lead to a weakening of its effects - some insects adapt and become less sensitive to this pesticide. Different insecticides must be alternated.
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.
Main characteristics of the product
Inta-vir is a synthetic analogue of naturally occurring pyrethrin poisons.
They are concentrated to a greater extent in chamomile or chrysanthemum flowers, protecting them from harmful insects that can destroy the inflorescence. The main active ingredient in the chemical composition of the insecticide is cypermethrin (3.75% consistency). The poison actively affects the nervous system of parasites, leading to paralysis and subsequent death of representatives of about 50 species of garden pests. Some of them die the very next day after poisoning. Other species are destroyed by repeated use of the product over 1-2 months. The drug is most toxic to the following types of insects:
- Colorado potato beetles;
- cabbage whites;
- moth;
- caterpillars - leaf eaters;
- sawfly;
- carrot fly;
- thrips;
- codling moths;
- bedbugs and others.
Inta-vir also helps against aphids. But the drug will be especially effective when used together with another chemical.
Plants remain neutral to the action of the active substance. But, unfortunately, Intavir can be dangerous for beneficial insects that pollinate flowers. Therefore, you should not use an insecticide unless absolutely necessary or for preventive purposes.
Inta-vir is also used for indoor plants. However, this should be done with caution, primarily because the drug is toxic. After using it, the room should be left for several hours and then thoroughly ventilated.
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;

"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;

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.
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
Reviews about the use of Intavir
BavBav47.
For many years I have been using various poisonous agents against insect pests in the garden. In recent years, I have kept several substances in my arsenal without which it is simply difficult to grow anything in my garden. One of them is Inta-vir. Effective, easy to use.
Zerkana.
Many experienced gardeners do not pursue modern and expensive insecticides, but prefer the old and proven Intavir. Of course, this drug cannot cope with the most harmful aggressor of our gardens - the Colorado potato beetle. The beetles are now becoming more persistent and bolder every year. But against caterpillars, aphids, and midges that attack our vegetables, you can use Inta-Vir calmly, with the expected good results. We bought this product to preserve cabbage. The effectiveness of the drug against caterpillars, midges, and aphids is good. Therefore, I will recommend Inta-vir as an inexpensive and effective insecticide.

I want to tell you about a wonderful remedy that kills pests. Pests periodically appear in my pots with indoor flowers. Most often these are midges - thrips. And once these bastards appear, it’s hard to get rid of them. This is where the Inta-Vir product, which I have tested more than once, comes to the rescue - such a large tablet in a package.
Trust.
We have been using Inta-Vir tablets for five years. We mainly use it for spraying young cabbage plants. It is unrealistic to escape from cabbage aphids using traditional methods (ash, etc.). cabbage, gardeners will understand me, dies in a matter of hours. We dilute Inta Vir with a weak solution, half the recommended one, the result is still excellent. There is one important feature: after rain it is worth spraying the cabbage again; rain usually washes off the preparation. We also use the drug on young apple trees (they are not yet bearing fruit). We don’t know exactly who “wraps” the leaves on them. This happens immediately after the leaves bloom. Two treatments with Inta-vir per season and the problem is solved.

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.
