Fipronil, the active active ingredient of the remedy for the Colorado potato beetle, regent and regent 800, belongs to a new class of toxic chemicals and the instructions for use of the drug indicate that it is assigned hazard class 2. This is a highly effective tool that is enough to spray a field or garden just once a season to get rid of the Colorado potato beetle and protect the future potato crop.

Handling it requires caution, but not only the Colorado aggressor, but also many other pests who have not had time to develop resistance to it can be blasted. The compound has only recently been developed and is a prolonged-acting enteric-toxic toxic insecticide. Insects are able to significantly reduce or ruin the expectations of the vegetable grower from his efforts and means in planting a potato field. The regent destroys them in a short time and at any stage of development.

The remedy for the Colorado potato beetle regent and regent 800, despite the relatively recent entry into wide retail sale, is more effective than neonicotinoids, pyrethroids and organophosphorus preparations. Instructions for use warns of the need to observe certain precautions. User reviews indicate a high efficiency and 100% result of toxic powder, which can even etch cockroaches in a residential building.

The regent is an insecticide from the German concern BASF, whose plants are located in many parts of the globe, including in the Russian Federation and has analogues similar in toxicity and mechanism of action, among products from a domestic manufacturer.

In this case, the guarantees of effectiveness and preference factors may be adherence to technology in complex chemical processes, characteristic of the German industry, and high quality.

Description and characteristics of the drug

The remedy for the Colorado potato beetle Regent is relatively recent in the market of chemical preparations. Related to toxic insecticides of 2 degrees of danger to humans, with an intestinal-contact mechanism, it has a prolonged, but reliable effect. Among the features include the use of the newly developed active active substance fipronil. It was created by chemists of a well-known German industrial concern, based on the already proven compounds phenylpyrazoles.

Tip: A favorable period for the destruction of the population by the Regent from the Colorado potato beetle is the moment of the appearance of an adult individual that can give extensive offspring, or the period of hatching of larvae that did not have time to acquire resistance to the drug used.

The period of action of the Regent lasts another 2-3 weeks (depending on the diluted amount), which allows you to remove from the site not only existing adults and hatching larvae, but also offspring that will appear from the eggs after the beetles die. In this regard, the manufacturer positions its development as a chemical agent that has no industrial analogues. Its action, which occurs after intestinal or contact contact with the beetle, for 12-24 hours, reduces vital activity before death, and does not allow the production of new ovipositories.

The duration of the period during which the drug has toxic properties, leads to the complete destruction of the population of Colorado leaf gnaw.At the same time, it also allows you to get rid of other insects that pose a threat to the deciduous mass of the potato bush - aphids, spider mites.

In the characteristics of the Regent from the Colorado potato beetle, invested by BASF in each package, the instructions for use include the following parameters:

a wide range of insecticides;
a poisonous substance for insects, created on the basis of the active active substance fipronil, a derivative of the already known class of chemical compounds - phenylpyrazoles;
class 5 drug, the latest development, to which the pest has not developed resistance (unlike others, partially or completely, which have lost danger due to the addiction of insects to them);
has a double, intestinal and contact mechanism of action;
available in several types of packaging, there are different forms of the drug for ease of use by consumers;
does not lose toxicity in heat, because it is resistant to high temperature (other drugs of this class and toxic properties lose their effect due to the instability of the compounds);
translaminarity of poison from the Colorado potato beetle Regent is ensured by the absorption of leaves and stems of the plant, (potato bush gets the opportunity to protect themselves from the aggressor);
for the safety of the field or the garden, one treatment per season is enough (the Regent drug from the Colorado potato beetle lasts for 20-30 days and manages to completely destroy the population)
the concentration of the active substance is 800 g per 1 kg of powder or granules, and the ampoules contain a concentrated solution, which makes it possible to dispense with a small amount, and makes the purchase profitable;
It has minimal penetration into fruits and tubers: during processing it is not dangerous for future food products.

Interesting: The active active ingredient of the Regent venom from the Colorado potato beetle, fipronil, wallows the nerve center blocker responsible for the synthesis of gamma-aminobutyric acid. Beetles, when the product enters the body or intestines, die from paralysis.

Principle of action, composition and toxicity

The insecticide Regent, as notified by the manufacturer’s instructions, when used against any insects, including the Colorado potato beetle, has a double mechanism of action on a pest dangerous to the potato field:

contact, based on contact with the body of the insect and having a poisonous effect on the beetle or larva when in direct contact;
intestinal, (ingestion of poison in the body of the pest when eating leaves, and absorption when digesting food, with a diluted chemical composition.

Additional, translaminar, is achieved by the ability of the Regent from the Colorado potato beetle to penetrate into the plant cells and spread through them. This provides protection for those segments of potatoes that the poison didn’t fall into when sprayed. The gardener does not need to worry that the insecticide is sprayed onto the lower leaves or stem, hidden by the upper layer of green mass.

Note: It does not matter in what form the industrial product is acquired, in solution or in powder, because it is still applied to the plant in diluted form. You need to consider only the area that can be processed using packaging, focusing on the existing need.

The composition of any type in which Regent is produced (powder, granular preparation and concentrated solution in sealed ampoules) includes 800/1000 of the active active substance - fipronil from the class of phenylpyrazoles.Ampoules have a longer shelf life, but may be inconvenient in opening for an inexperienced vegetable grower, and the powder can be dangerous for the child to whom he will fall into the hands.

Important: The Regent Powder instructions for Colorado potato beetle include a special item on the possible risks that the product may pose if it falls into the hands of children. Therefore, storage conditions are especially stipulated (in a dark, cool place, out of reach for them).

The toxicity of Regent and Regent 800 in the instructions for use against all insects, including the Colorado potato beetle, is hazard class 2 for humans and fatal effects on insects. But the chemical does not possess phytotoxicity, and is absolutely safe for the plant. It penetrates into the stems and leaves, but does not get inside the fruit, so it is rational to use the Regent from fruit pests only if at some stage of development the pests are on the surface.

Application and safety measures

Reviews of vegetable growers indicate the highest effectiveness of the drug Regent from the Colorado potato beetle, which occurs when the necessary conditions for breeding and distribution are described in detail in the instructions from the manufacturer.

A 500 gram package with water-dispersible granules, powder or ampoules with a concentrated solution are diluted in room temperature water. It is necessary to calculate the amount of the required solution. With a significant spread of the pest population and a large number of adults per 1 hundred parts, 1 ampoule, or 10 l of powder solution (10 l - 5 g) may be required. With a lower intensity of distribution, 1 ampoule per 2 hundred parts of a plot or 5 l of solution, which are applied directly to the bushes, by spraying or spraying is sufficient. When using a remedy for domestic insects (cockroaches, Prussians, bugs), the ampoule is diluted in 300 or 500 ml of water.

For reference: Spraying should be carried out using protective equipment for the respiratory system, face and hands. To protect yourself from the contact action of the poison, it is better to use clothes with long sleeves and trousers, a protective mask or a respirator.

You can store the packaged product at an average temperature for the expiration date indicated on the package, out of the reach of children. The finished solution retains its properties for no more than a few hours.

Fact: Today, Regent is one of the most effective insect-toxic chemicals of the 5th generation. The Colorado potato beetle has not yet managed to develop resistance to such drugs, so the use of Regent from the BASF company will help solve the problem and get rid of pests of potato plantings.
