The product is recommended for use in household plots and large farms as a reliable insecticide effective against 50 varieties of horticultural pests.

The main active ingredient in the composition is cypermethrin. The concentration of the substance in Intavir is about 38 grams per 1 kg. After spraying the plants, a microfilm is formed on its surface, which, when sprayed with the preparation, covers the surface of the plant with a microfilm.When the agent enters the body of insects that harm potato plantings and eat foliage, it leads to paralysis of pests and their death within 24 hours. The effect of the chemical lasts for two weeks after spraying the shoots.

What are the advantages and disadvantages of Intavir?

On the market of modern chemicals designed to combat garden pests, today there are quite a large number, among which Intavir stands out favorably. For the first time, such a remedy was developed on the basis of a pomace from medicinal plants such as chamomile and tansy

Chemical benefits include:

high efficiency against pests;
the ability to deal with a large number of varieties of pests with one tool;
duration;
excellent combination of price and quality parameters;
safety for humans and warm-blooded animals;
lack of quality of accumulation in plants, since after 20 days the main active ingredients completely decompose into harmless elements.

The drug is effective for fighting not only the Colorado potato beetle, it does an excellent job with thrips, white butterflies, carrot flies, aphids and a number of other pests of horticultural crops. One of the advantages of a chemical agent is the possibility of its use in a greenhouse. The tool is one of the few that does not have an unpleasant specific odor.

Among the disadvantages of the chemical preparation is a special requirement for weather conditions for the possibility of spraying shoots. They can be carried out only in the absence of rain, so during precipitation the drug is washed off with water, and its effectiveness is reduced.

How is Intavir used?

To use the drug for pest control, an aqueous solution is preliminarily prepared, which is then used to spray plants. To do this, take one tablet or sachet for dilution in 10 liters of warm water. First, the drug is diluted in a small volume of water, gradually bringing the amount to the recommended value. If it is necessary to treat a small area of planting potatoes, it is allowed to use half a tablet, while the amount of water should be reduced to 5 liters.

The best time for spraying is in the morning or evening hours. Processing of potato plantings from the Colorado potato beetle is carried out in dry weather without wind at a temperature of no more than 25 ^{C. Shoots are processed completely, including carefully processing the inner and outer surface of the leaf plates.The application of the solution is carried out by a continuous method, avoiding the presence of untreated places during work, even if there are no obvious signs of larvae or beetles on the potato.}

The product can be used to control pests of other garden plants. In this case, it is recommended to adhere to the following recommendations:

thrips, aphids - 8 grams for every 10 liters of warm water;
codling moth, caterpillar - 1 tablet diluted in a bucket of water with a volume of 10 liters;
weevil - 1.5 tablets per 10 liters of water, sprayed during the growing season;
Whitefly - 2 tablets for every 10 liters of water.

The processing of such plants is carried out during the growing season. Currant glass is treated with a solution of 1 tablet dissolved in 10 liters of water in the period before and after flowering.

The drug is effective not only for the fight against the Colorado potato beetle.The tool can be used to treat "house plants". To do this, the tablet is divided into 8 parts, the resulting share weighing 1 gram is dissolved in 1 liter of water. On average, a working solution in this amount is enough for half a standard window sill, completely filled with plants.

Important points

Intavir must be used to control the Colorado potato beetle only when pests appear. For prophylactic purposes, the drug is not used. During one season, the processing of potato plantings is carried out 3 times and only after the flowering of the horticultural crop.

The last spraying is carried out 20-25 before harvest.

Only a freshly prepared solution is used for work, therefore, when planning work, it is necessary to take into account the size of the area of potato plantings. After spraying, the diluted solution cannot be stored.The calculation of the volume of the working solution required for processing is carried out taking into account the fact that 1 package of the remedy for the Colorado potato beetle falls on 1 hundred square meters of potato plantings.

When working, it is important to follow safety measures and precautions. The rules for using pesticides in pest control are as follows:

work is carried out in personal protective equipment, that is, in special clothing, goggles and a respirator;
do not smoke or eat food while spraying;
after finishing work, you must take a shower, carefully treating all parts of the body with water;
should not be sprayed on women during gestation and lactation.

In case of contact with the mucous membranes or skin, the affected area must be thoroughly rinsed with plenty of water. If the product is ingested, you must drink a liter of plain water, induce a gag reflex and seek help from a medical facility.

It should be borne in mind that the remedy for the fight against the Colorado potato beetle is effective only if the shelf life is 4 years from the date of manufacture. Store the pesticide in a cool dry place that is inaccessible to small children and pets.
