Reviews

Andreev: Tanrek is the best remedy for controlling aphids on currants: the pests curl the leaves, and treatment with other drugs is ineffective, but Tanrek copes because it is a systemic drug.

Natalya: I would not say that Tanrek does not drip from the leaves of plants. It still drips, especially from the pubescent ones. But the drug is good, so I add flea shampoo to the solution, which helps Tanrek deal with ticks: I drop 5 ml of shampoo onto a bucket of working solution.

Nikolai: I don’t know a better remedy for the Colorado potato beetle, although I’ve tried everything in my life. Unfortunately, in rainy summers you have to treat potatoes more than once, because the drug is washed off. But next year I will add an adhesive to the working solution. Let's see how it turns out.

Irina: I poisoned the red lily beetle with Tanrek, which was disfiguring the leaves of the lilies, and there was no mention of my pest on the packaging in the instructions. However, the drug worked perfectly.

Tatyana: It’s not true that one treatment with Tanrek per season is enough. Especially during the rainy season. But the drug copes with the beetle better than all other products that I have used in the potato field year after year. So for now Tanrek is a champion for me.

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.

Advantages and disadvantages

• 100% destruction of insects;
• the drug actively “works” against individuals that are located on the underside of the leaf;
• effective regardless of weather conditions and temperature indicators;
• Tanrek has no resistance, which allows its use, subject to the rules, for a number of years in one area;
• there is no phototoxicity (subject to compliance with dosages and volumes of consumption);
• can be used for treating soil, as well as for soaking seed material;
• Sharing with Fitosporin is acceptable.

The product can be used for treatments using aviation (relevant for planting on an industrial scale). The insecticide provides protection for up to two to three weeks, while the consumption rates are insignificant.

Gardeners' opinion about the drug

Reviews of the insecticidal agent Tanrek indicate its destructive effect not only on the Colorado potato beetle, but also on aphids, cutworm caterpillars, and spider mites.

Summer residents advise that if you dilute the drug, you should use it immediately. It is not recommended to store Tanrek in solution, since the toxic substance can poison animals and children.

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.
