Consider the instructions for the use of the Talstar insecticide, the composition and form of release, the mechanism of action and purpose, correct use, consumption rate, dosage for different crops. Is it possible to combine an insecticide with other pesticides, how to store it, are there any substitutes.
Composition and form of release of funds
Talstar manufactures FMS Chemical in the form of emulsion concentrate in 5 liter canisters. Its active compound is bifenthrin, in an amount of 100 g per 1 liter. The insecticide has an intestinal and contact effect.
Spectrum and mechanism of action
According to the instructions, "Talstar" is used on tomatoes and cucumbers grown in greenhouses, from aphids, spider mites and whiteflies. But the agent is also used to treat cotton, grain and fruit crops, grapes from the same pests, as well as from thrips, bedbugs, leaf rollers, moths and leaf-eating insects.
Bifenthrin, like all substances from the pyrethroid class, acts on the nervous system of pests. The destructive effect is manifested on insects at all stages of development: eggs, larvae and adults.
Symptoms of poisoning are similar to those of organochlorine drugs: first, the insects are very agitated, then paralysis sets in. The substance disrupts metabolic processes in cell membranes. In addition to insecticidal, bifenthrin has a repellent effect.
Insects and ticks do not get used to "Talstar", the drug has a long protective effect, is not phytotoxic, does not poison humans and animals. The tool is economically consumed, it is beneficial to use it, because it has both insecticidal and acaricidal properties.
Application of a highly effective insect-acaricide
For greenhouse tomatoes and cucumbers, the rate of application of Talstar depends on the pest (in liters per hectare):
- greenhouse whitefly - 1.2-2.4;
- spider mite - 0.6-1.2;
- aphid - 0.4-0.8.
A one-time treatment is carried out, 1000-3000 liters per hectare are consumed for all crops. The waiting period for tomatoes is 3 days, for cucumbers - 5 days.
When applied on apple, cotton and grapes, Talstar also has an effect on ticks, so by treating it, you can reduce the amount of other acaricidal sprays.
Spray cultures with a solution prepared before starting work. The death of insects continues for 12 hours. The duration of the protective effect of the drug is 30-40 days.
Safety precautions when working with Talstar
The product has a hazard class for people - 2, which means moderately hazardous substances. For bees, the drug is poisonous, hazard class 1. It is prohibited to use the agent in gardens during flowering and summer bees. You can not use "Talstar" in the area of reservoirs, fish farms and water sources.
Work with Talstar solution and prepare it in tight protective clothing, put gloves on your hands, and a respirator and goggles on your face to prevent the solution from getting into your eyes and nose. During spraying, do not smoke, eat or drink, remove personal protective equipment. After work, wash your face and hands with soap and water.

If after washing the condition does not improve, you need to see a doctor. You can work with sprayed plants 3 days after treatment.

If, when mixing in a small volume, no chemical interaction occurs, then pesticides can be mixed, if there is a change in the color of the liquid, temperature, precipitation occurs, then they cannot be mixed. You need to either pick up another tool, or process it after a while.
