All kinds of mineral additives and natural fertilizers help summer residents and gardeners grow crops and reap high yields. However, it is important to ensure the safety of the crop. Thanks to Dakfosal, it is possible to effectively get rid of rodents and destroy insect pests. Handling the substance requires attention and caution due to its high toxicity.
Composition and active ingredient of the insecticide
The drug is available in the form of tablets packaged in bottles.Standard packages are 0.3 kg and 1 kg. Insecticide composition: aluminum phosphide, phosphine (affect the breathing of insect pests or rodents, causing paralysis of the nervous system). The peculiarity of the action of the product is gas activity.
Activation of Dakfosal tablets occurs under the influence of moisture in the air. It is the released phosphine gas that provokes paralysis of the spiral muscles of the pests and interrupts active breathing. For high effectiveness of the drug, an adequate amount of oxygen is required, otherwise low mortality of insects is observed.
In what cases is it used?
The product is actively used for disinfestation of empty storage facilities, warehouses, elevators, in which grain is stored in bags or in bulk under films. The drug has a wide range of effects on pests (insecticide, rodenticide, acaricide). "Dakfosal" is used to treat granaries in order to destroy granary weevils, grain borers, tobacco beetles, mill moths, grain moths, flour beetles, mites and other pests.
In open spaces, the product is used to protect areas from moles and other diggers. Moreover, as a rodenticide, the substance is produced in the form of stickers. To destroy the animals, it is enough to stick “Dakfosal-anti-mole” sticks into each mole-hole entrance during the day.
Mechanism of action
The “functioning” of the drug can be divided into two stages. The active ingredient – aluminum phosphide – does not have pesticide properties. However, when it reacts with moisture in the air, it forms toxic phosphine gas. To cause severe poisoning, it is enough to inhale air for 10-15 minutes in which the concentration of the toxic substance is 1 mg / cubic meter. meter.
It should be noted that the gas has an unpleasant odor, and no symptoms of poisoning are observed in the first few minutes. The toxic effect of phosphine lasts 1-24 hours. If the room is ventilated for a long time, the gas breaks down into harmless substances.
Instructions for use of Dakfosal
Given the toxicity of the drug, the manufacturer's recommendations for use should be strictly followed.
| Processed object | Pest type | Drug consumption | Processing instructions |
| Empty granaries, warehouses | Harmful insects (except ticks) | 5 g/cu.m. meter | Premises are treated at an air temperature of at least 15 °C. Duration of processing – 5 days. Loading of premises is permitted after thorough ventilation. |
| Elevators filled with bagged or bulk grain | Insects and mites | 9 g/ton seeds, grains | The processing temperature conditions are maintained. In the presence of ticks, the duration of action of the drug is 9 days. People are allowed into the warehouse after ventilation |
Security measures
When treating premises, first of all, the amount of the required substance is calculated and a plan for the location of the tablets is drawn up.
Basic safety requirements:
- for the period of work with Dakfosal, a full set of personal protective equipment is worn (overalls, boots, gloves, a special respirator);
- when the first symptoms of suffocation appear, work stops; it is necessary to leave the premises;
- After processing the warehouse or elevator, you need to take a shower, and the PPE is sent for neutralization. The treated room is tightly closed, and information about the event is posted on the door.
Contact of tablets or granules with the naked body or exposed skin is strictly prohibited. You should also not smell the product. It must be remembered that at high air temperatures (from 30 ° C), the risk of a sudden release of phosphine increases, which can cause severe burns and poisoning.
Drug compatibility
The simultaneous use of Dakfosal and other insecticides is not recommended, since with an increased content of carbon dioxide in the room, the effect of phosphine sharply increases.
Storage rules
Given the high toxicity of the drug, it is strictly prohibited to store tablets in a warehouse or premises simultaneously with food, household or household items. Storage temperature range from -20 °C to +35 °C. The warehouse must be equipped with supply and exhaust ventilation. It is not allowed to place nitrogen fertilizers and Dakfosal in the same room.
To avoid the harmful effects of the drug on the human body or chronic poisoning, it is advisable to use the drug immediately after purchase.
What can be replaced?
A popular analogue of the drug is the product “Selfos”, which is also intended for protection against pests of grain storage facilities. Advantages of the drug: average toxicity, destruction of rodents and various types of insect pests, does not accumulate in grain, low consumption. To process 1 ton of grain, you will need three tablets.
The use of special preparations greatly simplifies the protection of grain crops from pests and ensures reliable destruction of rodents and moles. However, the toxicity of the products and the need to comply with safety requirements must be taken into account.
