Application and features of tanrek

• Mechanism of action: imidacloprid binds to nerve receptors in the central nervous system of harmful insects, causing paralysis, convulsions and death in them.
• Imidacloprid has systemic activity.
• Tanrek destroys only insects and beetles (weevil, ground beetle), does not affect arthropods (ticks).
• It has a long protective period (up to 30 days).
• Imidacloprid, when absorbed by the roots, enters the leaves, practically does not enter the fruits, therefore it can be used for drip irrigation for growing vegetables.
• Imidacloprid is highly stable in soil (half-life 50-100 days). 
• Tanrek's efficiency is independent of temperature.
• The drug is not phytotoxic on garden and garden crops
• Imidacloprid is stable at pH 5 to 7.
• Tanrek can be combined in tank mixtures with the fungicides Skor, Thanos, Topaz, Horus, tick remedies (Omait, Arrivo, Bi-58 new).

Tanrek from aphids, whiteflies and Colorado beetle

The manufacturer made a fuss for the most thought-weary gardener and released Tanrek in the same package under different names: one is declared as Tanrek from aphids and whiteflies, the other as Tanrk from the Colorado beetle. In fact, this is the same drug, with the same concentration of the active substance imidacloprid 200 g/l, only the instructions are different - on one norm from aphids, the other from Colorado beetle. I.e. you can buy any drug, it will work the same way.

Tanrek: reviews

Tanrek is, according to rukodelie.net/plants, the best remedy (not counting analogues) in the fight against aphids, especially on currants. The fact is that aphids on currants cause wrinkling of leaves, aphids hide on the back of shrunken leaves like in a house. Spraying with other drugs that do not have systemic actions is ineffective - the solution lies on the surface of the leaf without reaching the pest colonies and without wetting the surface from which they feed. Tanrek can spray bushes from above, the active ingredient penetrates the epidermis and spreads throughout the leaf through the vessels, thus tops and leaves become poisonous to aphids and other pests wherever they hide. However, the systemic effects of Tanrek are much weaker than intestinal contact.

The manufacturer claims that Tanrek is well applied to leaves, does not wash off with rain. It isn't. It depends on the culture - the solution clings well to the smooth leaves of gooseberries and currants, to cucumbers, tomatoes and potatoes with noticeable pubescence - it is bad, you need to spray through a small sprayer, it is better to add adhesives in 2-3 visits (best of all, a 5 ml flea shampoo per 10 liters of water) - it helps against ticks, since to poison, since there are as many pests as possible. In general, the efficacy of Tanrek on a ten-point scale can be assessed by 6-7 points.

Price for Tanrek summer 2016 on average: for a bottle of 10 ml 75-85 rubles, a bottle of 100 ml - 250-280 rubles, ampoules of 1 ml and 1.5 ml - 12-15 rubles.

Scale insects and mealybugs are direct relatives - they belong to different families of semi-winged insects. However, they have different resistance to imidacloprid and other neonicotinoids (Actare). Scale insects are more sensitive, usually two sprays are enough, 3-5 days apart, to get rid of pests. But worms are more resistant to this group of drugs. In order not to poison yourself and not to depress the plants once again, it is worth using another scheme for treatment from worms and shield: watering with Tanrek under the root (1 ml per 1 liter of water) + spraying with insecticides of the pyrethroid class (Decis) or FOS (Alatar, Fufanon).

Waiting times are the time after processing to harvest 30 days.
