Imidacloprid poses a moderate hazard to freshwater animals, so its use near bodies of water is permitted. However, due to the fact that the drug can have a toxic effect on bees, it is impossible to treat plants during flowering.

Features of the product's action

Tanrek against aphids
The drug Tanrek against aphids and whiteflies has some features of use:

• Imidacloprid is a systemic substance;
• destroys harmful insects and beetles (weevils, ground beetles), but is not effective against arthropods (ticks);
• long protective period – up to 30 days;
• toxic substances enter only the green parts of the plants, and not the fruits, so it can also be used for drip irrigation;
• Half-life in soil is 50-100 days, i.e. has high stability;
• non-phytotoxic for garden and garden crops;
• the insecticide can be diluted in liquid at 5-7 pH;
• is well compatible with fungicides: Skor, Thanos, Topaz, Horus, anti-mite drugs Omite, Arrivo, Bi-58, as well as Fitosporin.

On a note!

Some domestic flowers may have leaves that turn yellow after spraying with Tanrek; this applies to plants with more sensitive or thin leaves, conifers, orchids, etc. Therefore, it is recommended to first spray one branch or 2-3 leaves with the drug and observe. With severe phytotoxicity, the leaves will turn yellow within 2 days, but it is necessary to exclude other causes of this phenomenon: overdrying, sunburn or a large amount of fertilizer.

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.

Tanrek: consumption rates

The consumption rates of the prepared Tanrek solution are 10 liters per 100 m2 of leaf mass on herbaceous plants (cucumbers, tomatoes, potatoes) and from 2 to 5 liters per tree (depending on age and height), approximately 1-1.5 liters per currant bush and gooseberries.

Dosages: on apple, pear, currant, gooseberry, plum and other crops, the consumption rate is 3 ml Tanrek per 10 liters of water. Dosage for vegetables (cucumbers, tomatoes) - 5 ml per 10 liters of water, spraying potatoes against the Colorado potato beetle: 1 ml per 10 liters of water.

The working solution cannot be stored; after dilution, use immediately (can stand for a maximum of 3 hours).

• How to dilute Tanrek for spraying the Colorado potato beetle: pour 1 liter of water into a plastic bucket, measure 1 ml of the drug, mix, bring to a volume of 10 liters. Pour into a sprayer.
• How to breed Tanrek against aphids and whiteflies on fruit trees and shrubs: pour 1 liter of water into a plastic bucket, measure out 1.5 ml of the drug, mix, add water to a volume of 5 liters. Pour into a sprayer. When the solution runs out, dilute the next batch with 5 liters of water.
• How to dilute Tanrek against aphids and whiteflies on vegetables: pour 1 liter of water into a plastic bucket, measure out 5 ml of the drug, mix, add water to a volume of 10 liters. Pour into a sprayer.

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.

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.

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. The solution adheres well to the leaves of the treated plants. But for better adhesion, it is better to add shavings of laundry soap to the working liquid, mixing thoroughly.

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. It is also dangerous for beneficial insects. By treating potatoes with insecticide, they protect the respiratory tract and eyes from toxic liquid getting on the mucous membranes.

Vegetable growers rate Tanrek on a ten-point scale of seven to eight points, which indicates the effectiveness of the insecticide. The drug is convenient because it is useful for treating fruit and berry crops and indoor plants against pests.

• potato scoop;
• scale insects;
• ground flies;
• garden bugs;
• aphids;
• ground beetles;
• locusts
