"Tanrek" is a systemic insecticide with acute contact-intestinal action. The material includes purpose, composition, mechanism of action, regulations for use, compatibility, analogues, restrictions and safety.

Purpose and application

The drug is widely used in private farms to protect potatoes, cucumbers, tomatoes, flower and ornamental crops to combat a large number of different pests. Among them are aphids, whiteflies, Colorado potato beetles, apple flower beetles, thrips and many others. etc.

In agriculture it is used on wheat and other cereals for protection against harmful bugs and ground beetles, as well as for treating pastures and areas inhabited by locusts.

Reviews from gardeners about Tanrek

• Alevtina . It coped relatively well with pests – not only gnawing ones, but also sucking ones. I just read that the latest research has found that neonicotinoids (to which this drug belongs) turn out to be the cause of the widespread death of bees and the pestilence of wild pollinators in Europe and some other Latin American countries. That’s why these drugs are now banned there, but here they sell them as before. If you care about nature, think about it.
• Anna . I sprayed my roses with Tanrek - they bloom beautifully, it helps! I saved cucumbers from aphids with this remedy; I diluted a 10-liter ampoule. A neighbor sprayed his neglected shrubs and trees on the property (there were aphids and cobwebs), although together with another drug, Raek - after 2 weeks there was not a single parasite left! But the fruits and berries remained clean.
• Ioannina . It helped me get rid of aphids on house plants and flowers - they disappeared. But I diluted the solution not according to the instructions, but a stronger one - an ampoule for half a liter of water. Mom treated currants with Tanrek at the dacha - they also disappeared after the first application and never returned.

Instructions for use

The working composition cannot be stored, so prepare the solution immediately before use.

On a note! The insecticide solution prepared according to the instructions is produced within six hours.

Basic Rules:

1. Plantings are processed on a clear day, preferably without wind.
2. The time of day does not matter, but for safety it is better to schedule work in the morning or evening.
3. The type of pest, the characteristics of the crop being treated, and the area are taken into account.
4. Any model of sprayer (metal, plastic) is suitable for treatment, since the drug is neutral in relation to materials.
5. Consumption is strictly according to the instructions.
6. Application is indicated only in cases where all other options and methods of protection have been exhausted, and the entire harvest is at risk.

Treatment for all crops is one-time. Knowing how to breed Tarnek from the Colorado potato beetle, you can add other means to it for effectiveness.

It is allowed to mix in tank mixtures with some fungicides, as well as anti-tick medications:

• Topaz – from the mycelium of fungal pathogens;
• Horus is a broad-spectrum fungicidal agent;
• Bi-58 – from sucking and gnawing insects;
• Omite is from the category of acaricides.

On potato plantings

On potato plantings, Tanrek against the Colorado potato beetle is used against all generations of the insect. Prepare a solution by dissolving one milliliter of the product in a bucket, spending five liters per hundred square meters. Before digging the tubers, wait at least 20 days.

On tomatoes

It is effective to use an insecticide in a tomato greenhouse, where there is a high risk of plants being damaged by the Colorado potato beetle or the insidious whitefly.

Working solution for plants in greenhouses - take 5 ml of concentrate per bucket. Consumption – 1-3 liters per 10 square meters. meters (taking into account the number of pests) and the age of the plants.

On cucumbers

For greenhouse plantings, the working mixture is prepared in the same proportion as for tomatoes. All bushes are sprayed completely; harvesting greens is allowed after three days. It is believed that Tanrek helps against aphids and whiteflies better than other drugs.

On the apple trees

The drug has shown itself to be effective against aphids and apple blossom beetle. Treatment is allowed before the apple trees begin to bud or after, when the apples begin to set.

Dilute the composition in a proportion of 3 ml per 10-liter bucket, spray 2-5 liters per tree. For seedlings the volume will be less (2-3 liters), for adult apple trees - 5 liters.

On currants

Aphids cause great harm to berry bushes. Tanrek is diluted in a ratio of 3 ml per 10 liters of water, sprayed at 1.5 liters per bush.

On a note! Treatment of any fruit and berry plantings is carried out before flowering. Less often - after flowering, in the stage of ovary formation.

On flower crops

The main enemies of gardeners are leafhoppers, aphids, whiteflies, and thrips. The use of Tanrek is effective, but it is necessary to observe the proportions and consumption of the compositions for plants in beds and those growing at home on window sills or balconies.

Solution: 3 ml per ten-liter bucket of water (open ground) or 5 ml per the same amount of water for indoor flowers. Spraying during the growing season, also before flowering.

In orchids and conifers, distinguished by delicate leaf blades, yellow spots may appear. But if the dosage is observed, these phenomena disappear after 1-2 days.

Fatsia, schefflera, and streptocarpus are also sensitive to Tanrek.

On cereals

Most often, the insecticide is used on wheat plantings. Seedlings or crops are sprayed against ground beetles and harmful turtles during the growing season. Dilute 20 ml per 100 liters of water, this amount is enough to spray one hundred square meters of field.

In the pastures

The danger for pastures is posed by hordes of locusts, instantly devouring all plants and turning green lands into deserts. Tanrek has shown itself well in the fight against locusts.

For treatments, prepare a composition of 5 ml per 100 liters of water, spray the areas at the stage of larval development.

They spend approximately 20-50 liters per hectare, while access to pastures after treatments is allowed no earlier than 14-16 days later.

Mechanism of action "Tanrek"

"Tanrek", having an acute contact-intestinal effect and pronounced systemic activity. Imidacloprid enters all parts of the plant (leaves, stem and roots) through sap flow and affects the nervous system of harmful insects, blocking nerve connections and suppressing signal transmission through the central nervous system of pests. Insects die from overexcitation, then stop feeding and die within 24 hours.

It is important to note several distinctive features of the drug:

• the drug acts on both adult insects and larvae of different ages;
• unlike pyrethroids, Tanrek reduces its effectiveness at high air temperatures, and is also quite resistant to washing off by rain and exposure to sunlight;
• The mechanism of action of the drug "Tanrek" is different from pyrethroids, organophosphorus compounds, and carbamates, which allows it to be used effectively when alternating insecticides of different chemical classes.

The period of protective action is at least 14 - 21 days after treatment (depending on the pest and crop).

The speed of initial impact is within a few hours after treatment.

Precautionary measures

Due to the high danger of imidacloprid for beneficial insects and the hidden possibilities of its impact on humans, the following protective zones for working with the Tanrek insecticide are established:

• Recreation areas, children's and medical institutions - from 150 m.
• Residential buildings, incl. temporary, open poultry houses and livestock yards - from 50 m.
• Outbuildings and closed premises for keeping animals – 15 m.
• Reservoirs, water supply sources - according to their cadastral protection zone, but not less than 1.5 km.
• Apiaries, wild pollinator reserves – from 6 km.
• There is no restriction on the flight of bees, because It is impossible to isolate them during the decay of the drug in plants.
• Allowable working time with the drug is 4 hours.

PPE

Imidacloprid quite actively penetrates the human body through the mucous membranes, through the respiratory tract and during the reabsorption of fat. Therefore, PPE for working with Tanrek must be selected especially carefully. You can wear regular waterproof shoes; Protect the body over clothing with a waterproof raincoat with a hood.

Latex gloves are not suitable for hands; protective ones for pesticides are needed. The lightest (and cheapest) single-layer ones, pos. 1 in Fig. If you fork out for 2-3 layer gloves, it won’t get any worse.

Personal protective equipment for working with pesticides

Imidacloprid is slightly volatile, but a simple petal respirator (item 2) will not protect against its vapors. A filtering respirator with a full-face mask (item 3) is a pleasure for about $300 or more. Even professionals who work with toxic chemicals often replace it with a respirator with gas cartridges (item 4) and closed safety glasses (canned glasses).

But, firstly, part of the facial skin still remains unprotected. Secondly, canned glasses come in different varieties. Industrial ones without face seals (item 5) are not suitable in this case - they protect from sparks, dust, shavings, but not from toxic fumes - and safety glasses for toxic chemicals are also expensive.

Goggle-respirator kits are sold specifically for use in private household plots, pos. 6. Their resource is much less than professional facial PPE, but the price is not ungodly. To work with Tanrek and other toxic chemicals with a hidden potential for danger, it is better to supplement the kit with a face shield that protects against splashes (item 7), medical or homemade from polycarbonate.

First aid

Symptoms of imidacloprid poisoning are shortness of breath, lethargy, decreased motor activity (lethargy), trembling of the limbs (tremor), drooping eyelids. If it reaches them, the accumulation threshold in the body has been exceeded. The victim must be immediately taken to a doctor - self-help measures will only harm, there is no antidote, treatment is symptomatic.

Storage

Tanrek is stored under the usual conditions for toxic chemicals: in a separate non-residential premises, inaccessible to children and animals. An additional condition is waterproof flooring (for example, linoleum), because Tanrek should be bred in a specially adapted room. Neutralizing a drug spilled on the ground is ineffective, and it needs to be collected from the floor with a disposable rag (a large wad of toilet paper works well), then wipe the floor with a solution of baking soda or soda ash (3-4 tablespoons per 1 liter of water) and wash the floor with water. Wet rags along with empty packaging are burned or taken for disposal at a special collection point.

Processing regulations

Treatments are carried out by spraying. The concentrate is dissolved in 1/3 of the required volume of water, mixed thoroughly, and water is added to the full volume. The working solution cannot be stored and must be used on the day of preparation. During operation, stir periodically.

How to dilute Tanrek for indoor flowers: measure the required amount of the drug with a syringe, pour it into a plastic bottle with water. Dosages: for plants 1 ml per 2 liters of water or 5 ml per 10 liters of water. In some plants, yellowing of the leaves may occur after spraying, especially plants with thin, delicate leaves, conifers, and orchids. It has been noted that plants of the Arliaceae family (Schefflera, Fatsia) and the Gesneriaceae family (Aeschynanthus, Streptocarpus) are sensitive to tanrek (and analogues). It is worth diluting the drug 0.5 ml per 500 ml of water and spraying one twig or a pair of leaves. If phytotoxicity is present, yellowing will occur within a day, to a maximum of two days. However, other factors that cause yellowing of the leaves (overdrying, overwatering, sunburn, overfeeding with fertilizers) should be excluded.

Scale insects and mealybugs are direct relatives - they belong to different families of hemipteran insects. However, their resistance to imidacloprid and other neonicotinoids (Aktare) varies. Scale insects are more sensitive; usually two sprays are enough, with an interval of 3-5 days, to get rid of the pests. But scale insects are more resistant to this group of drugs. In order not to be poisoned yourself and not to depress the plants once again, for treatment against scale insects and scale insects it is worth using another scheme: watering with Tanrek at the root (1 ml per 1 liter of water) + spraying with insecticides of the pyrethroid class (Decis) or FOS (Alatar, Fufanon).

Waiting time - the time after processing until harvest is 30 days.

Toxicity

Tanrek is dangerous for fish, bees (hazard class 1), beneficial insects, moderately toxic for warm-blooded animals and humans when administered orally (if swallowed), the main impact is on the liver, in addition, disturbances in the rhythm of breathing and coordination of movement, tremors, diarrhea, and convulsions may be observed. Urgently induce vomiting, rinse the stomach, and seek medical help.

Sometimes when spraying at home, headache and nausea are observed - in cases where the room is not ventilated.

Half-life in soil is up to 190 days.

Security measures.

Spraying in a respirator, diluting the solution strictly while wearing gloves. After work, wash your hands with soap. Store the drug in a cool, dry place at a temperature of about 5-15C, separate from food and medicine, out of the reach of children and pets!

Restrictions and security

a) For humans and warm-blooded animals - hazard class 3 (moderately dangerous compound). When working with the drug, follow generally known personal safety standards and use PPE. The work is carried out in accordance with the current regulations GOST 12.3.041-86 and SanPiN 1.2.2584-10.

DATES FOR LEAVING people to carry out manual and mechanized work:

• open ground - 3 days;
• protected ground – 1 day.

WAITING TIMES before harvest:

• for open ground (wheat, pumpkin, potatoes) – up to 20 days;
• for protected soil (tomato, cucumber, leafy greens, salads) - at least 3 days;
• on flower and ornamental crops – the period is not regulated.

b) “Tanrek” belongs to the 2nd class in terms of resistance in soil. The drug is toxic to earthworms.

c) For bees – 1st hazard class (highly dangerous). Treatments are carried out in accordance with the “Instructions for the prevention of bee poisoning by pesticides” (Moscow, 1989). It is necessary to notify local apiary owners about treatment zones, treatment times, the product used, etc. Treatment during the flowering period and during the active flight of pollinators is completely prohibited. Plants are sprayed only in the early morning or late evening, at wind speeds of up to 2 - 3 m/s. The border protection strip for bees is at least 4 - 5 km, the flight of bees is limited to at least 96 - 120 hours.

d) Fishery assessment - 2nd hazard class. The use of the drug in the sanitary zone of fishery reservoirs is permitted, subject to compliance with the regulations. It is prohibited to discharge the drug into any water bodies, including sewers and septic tanks.

Advantages and disadvantages of the drug

Due to its affordable price and good effectiveness, the product is very popular. Therefore, you need to know more about all its advantages:

• inexpensive;
• protective properties last for 2-3 weeks;
• kills all insects within 3 days;
• does not have a toxic odor, so it can be used on the balcony, for example, for removing bees;
• effective for seed treatment;

• popular, so you can buy it at any pharmacy;
• even kills cockroaches;
• supplied in different volumes, there are no difficulties with preparation;
• can be used even in summer or winter;
• Suitable as a prophylactic drug.

However, Tanrek also has disadvantages:

• not effective against ticks;
• use only in the morning or evening, because in the sun, plants can be damaged by the action of the drug;
• unfortunately, the ampoules are not equipped with a measuring scale, so for dosage accuracy, you need to use a syringe;
• If used incorrectly, some indoor plants may have leaves that turn yellow.

By the way, you need to be very careful with indoor plants. This is where you should be wary of the “more is better” rule. An overdose can lead to the death of the plant.

If you often use a product to control one pest, for example, 3 times in 1 season for potatoes. Then the 4th time the solution may not have any effect at all, since pests can adapt to such effects. In this case, it is better to alternate it with another remedy.
