Fumifos: instructions for use of the fumigant, composition of tablets and dosage

Fumiphos is an effective fumigant that helps control pests in grain stocks. Means differs in the expressed insecticidal and rodenticide properties. The composition helps to cope with 100% of pests that destroy agricultural stocks. It is used in various types of farms. The substance is characterized by high biological activity.

Active ingredient and formulation

The drug is available in the form of tablets. The active component of the product is aluminum phosphide. In 1 kilogram of the composition there are 560 grams of this ingredient.

Purpose and principle of operation

"Fumifos" emits a special gas - phosphine. The substance enters the body of parasites through the respiratory organs and stops the movement of electrons. It occurs in the fourth mitochondrial complex.

Rapid uptake of oxygen under the influence of stimulation with carbon dioxide provokes an increase in the toxic properties of phosphine. It is important to consider that at some stages of development, insects consume less oxygen. Therefore, they are considered more resistant to the action of phosphine. This applies to the stages of eggs, pupae and larvae in diapause. At the same time, adults and active stages of larvae are more susceptible to the effects of the drug.

The key benefits of Fumifos include the following:

• the use of the substance does not provoke a deterioration in the quality parameters of the grains and their germination;
• composition is easy to use - phosphine gas easily penetrates into any package;
• substance helps to quickly carry out high-quality and complete processing;
• composition is completely harmless if you follow the instructions for its use;
• substance has a high fumigation activity.

Instructions for use and dosage

When processing grain in the silos of elevators, Fumifosa tablets must be injected using a special dispenser. The bunker needs to be filled on short notice.

If the grains are processed in warehouses, tablets need to be distributed over the grain mass with special probes. When fumigating small batches of grains or processing bagged products, the drug is placed throughout the facility.

Specific dosages are shown in the table:

Unloaded granariesHarmful insects, except for mitesProcessing is required at temperatures above +15 degrees.The exposure period is 5 days. It is permissible to load the storage and let people in only after airing. At the same time, the volume of phosphine in the air should not exceed the maximum permissible concentration.9 grams per 1 tonFood seed grain, feed grain in bulk in warehouses, bagged stocks, small lots weighing no more than 200 tons temperature is more than +15 degrees. The duration of the exposure is 5 days. Degassing should take at least 10 days. Allowing people into the room is allowed only after ventilation. At the same time, the level of phosphine in the air should not exceed the maximum permissible concentration.6 grams per 1 cubic meter Different types of grain stocks in ship holds with an embankment of 4-6 meters Harmful insects, except for ticks Grain processing is required at temperatures above +15 degrees.Place the tablets in the grain is at a depth of 2 meters. In this case, it is recommended to use special gas-permeable capsules. The exposition takes 3 days. The degassing period is at least 8 days.
