The principle of action and the purpose of the tool

"Dexter" has a contact-systemic effect and helps against a wide range of parasites at different stages of the life cycle. The composition can be applied from the stage of the larva to the adult. The mechanism of action of a substance is related to its composition.Lambda-cyhalothrin is a contact-intestinal insecticide that affects the nervous system of pests. At the same time, the composition impairs the permeability of cell membranes and causes blockage of sodium channels.

The active ingredient immediately overcomes the cuticle of the parasite and produces a noticeable effect. This means that the substance leads to immediate paralysis and subsequent death of pests. Lambda-cyhalothrin does not get into the structure of plants, but remains on the surface of crops.

Acetamiprid has a systemic effect. When it enters the plant, it remains there for up to 3 weeks. Thanks to this, it is possible to achieve protection against pests that lead a hidden lifestyle. The composition also destroys those parasites that attacked the plantings after spraying.

The beneficial effect is to block acetylcholine receptors. This causes a pronounced nervous overexcitation of insects. As a result, the nutrition of pests stops, which leads to their death.

Thanks to the described characteristics, Dexter quickly destroys parasites due to the presence of lambda-cyhalothrin in the composition and gives a lasting effect due to the content of acetamiprid. The composition reliably protects crops. It can be used for routine spraying or emergency applications.

At the same time, the composition is suitable for processing different plants:

Dexter helps to get rid of harmful bugs, aphids, thrips on cereal spike plants. Also, the composition effectively destroys stem sawflies and bread fleas. With its help, it is possible to cope with intrastem flies.
On sugar beets, the composition helps to cope with beet fleas and weevils. Also, the composition allows you to get rid of the meadow moth and aphids.

The drug is characterized by a high speed of obtaining results.Within a few minutes, disorientation of the parasites and a complete cessation of food activity begin. Then comes paralysis, which leads to the death of the pest. Over the next day, the parasites die from dehydration. The period of protective action of the product is 2-4 weeks after treatment. It depends on the climatic conditions, the period of use and the variety of parasites.

Instructions for the use of insecticide

Spraying with "Dexter" should be done during the growing season of the crop. This is done when the stage of the economic threshold of harmfulness of parasites is reached. To cope with bedbugs, it is recommended to strictly observe the dosage. To destroy overwintered adults in the spring, it is required to treat the plants with the preparation. This will require 0.1-0.2 liters per 1 hectare. At the same time, wheat is at the stage of entering the tube.

This treatment will help further reduce the number of other parasites on cereals - thrips, wheat mosquitoes, aphids.As a rule, such spraying is combined with fungicidal substances. With a large number of bedbugs, such treatment is not enough. If you want to protect yourself from larvae, at later stages of development, the next treatment should be carried out with the Zepellin insecticide. It is used at a dosage of 0.15 liters per 1 hectare.

Minimum amount of substance is applied when it is necessary to destroy the larvae. The maximum volume is used with an increased number of parasites and with the destruction of adults. It is also required when combined with fungicidal substances. During the season, 1-2 sprays are required.

Because Dexter contains 2 active ingredients that belong to different chemical classes, resistance is unlikely to occur.

Safety

"Dexter" is highly toxic to bees. The border zone for them is at least 4-5 kilometers. At the same time, a summer restriction is required for at least 4-5 days. The beekeepers must be informed about the planned processing. This is done in 4-5 days.

The drug does not need to be combined with other insecticides, as it helps to cope with a large number of parasites. The composition is perfectly combined with other means that are used for plant protection. It can also be combined with micronutrient fertilizers that need to be used in the same time frame.

Before using a substance, it is worth evaluating the compatibility of drugs. To do this, it is recommended to make a small amount of the working solution.
