for use of Penokumarin-1

as a deratization agent in the fight against rodents in livestock, warehouse, residential premises, as well as in the field.

1. Trade name of the drug: Penokumarin-1.

2. Penokumari-1 is a product in the form of an emulsion containing 2% sodium salt of warfarin, an attractant and a foaming filler. Penokumarin-1 in appearance is a homogeneous emulsion (foam) from white to cream color.

3. Foam Coumarin-1 is produced in tin or aluminum cylinders with a volume of 170, 350 ml. The shelf life of the foam-1, subject to storage conditions, is 3 years from the date of production.

4. Store Penokumarin-1 in a closed packaging of the manufacturer, in a dry, cool place at a temperature from 0°C to 25°C. At subzero temperatures, the foam -1 freezes. After thawing, the drug is again suitable for use.

If the foam supply stops when the valve is pressed, the latter is removed from the cylinder head, replaced with another one, or washed with water and purged with a pump or a rubber bag.

5. Penokumarin-1 should be stored in places inaccessible to children.

6. Special precautions must be taken when disposing of unused and expired drugs.


7. Highly toxic rodenticidal agent for all warm-blooded animals. The essence of the rodenticidal action consists in inhibiting the biosynthesis in the liver of prothrombin and other proteins that ensure blood clotting (coagulation), with a simultaneous increase in capillary porosity. As a result, internal bleeding and pulmonary edema occur, followed by the death of rodents.

8. It has cumulative and skin-resorptive properties.


9. Penokumarin-1 is used as one of the effective deratization agents in the fight against rodents in livestock, warehouse, residential premises, as well as in the field.

10. Optimal foaming and trouble-free operation of aerosol packages is ensured by preheating the cylinder to 45°C and thoroughly shaking.

Deratization with Penokumarin-1 is carried out 5-7 days in a row. If necessary, it can be continued or repeated at any time until the complete extermination of rodents. Penokumarin-1 is used primarily for blocking rodent burrows with foam and for making food poisoned baits. These methods can be applied individually or in combination.

As the food basis of poisoned baits, the most attractive for rodents in specific conditions are used high—quality food products and feeds – grains of cereals, sunflower seeds, minced meat and fish, porridges, compound feed, bread crumbs, etc. At the same time, 1 kg of the food base is thoroughly mixed with 4-5 g of toxic foam, i.e. with the amount of it that is released from the aerosol packaging for 4-6 seconds.

In dry baits (grain, cereals), in addition to poison, you can add 1-2% sugar or powdered sugar. Ready-made baits are laid out in portions of 500 g or more in each bait point with the expectation of providing bait for a week. On an object with an area of 500-700 m2, there may be 3-7 such bait points (depending on the degree of its population by rodents).

Wet baits are laid out every evening for 3-5 consecutive days (preferably on paper) in portions of 100-500 g in places inaccessible to animals (under the floor, behind the lari, in free machines, along feed aisles, etc.) or in special deratization feeders.To block the burrows with poisonous foam, a jet of foam coumarin-1 is directed into a rat hole, releasing it for 4-8 seconds. The resulting foam clogs the burrow. The next day, if the foam is eaten or scattered, the blockage of the burrow is repeated. The treatment is continued for 3-7 consecutive days or every other day.


11. When working with Penokumarin-1, it is forbidden to smoke and eat. After work, hands should be thoroughly washed with warm water and soap. Tables and dishes in which the bait was prepared are washed with a 2% soda solution.

Persons who have carefully studied the instructions for its use are allowed to work on deratization using penokumarin-1.

Penokumarin-1 should be kept under lock and key in a special cabinet.

Rodent corpses need to be cleaned with a shovel, shovel, forceps or hands in rubber gloves. Collected corpses are subject to incineration.

12. Persons who are constantly working with the drug should be systematically under the supervision of a doctor. In case of suspected poisoning, in particular when hemorrhages appear on the mucous membranes, in the subcutaneous tissue, etc., it is necessary to urgently consult a doctor.

13. In case of poisoning of farm animals, a course of specific and symptomatic treatment is carried out. Gastric lavage is performed with 0.1% potassium permanganate solution, emetics are administered (0.1% apomorphine hydrochloride solution or 2% copper sulfate solution), adsorbents – activated charcoal, burnt magnesia and saline laxatives. As a specific remedy, blood transfusion containing a normal amount of prothrombin is used, or vitamin K or its synthetic analogues (vikasol, methionine) are prescribed. Intravenously – a solution of glucose, ascorbic acid, subcutaneously – caffeine – sodium benzoate, cordiamine, camphor. In mild cases of poisoning, recovery occurs after feeding animals increased amounts of alfalfa or fish meal containing vitamin K.
