“Fumifos” is an effective fumigant that helps control pests of grain stocks. The product has pronounced insecticidal and rodenticidal properties. The composition helps to cope with 100% of pests that destroy agricultural supplies. It is used in different types of farms. The substance is characterized by high biological activity.
Active substance and formulation
The drug is available in tablet form. The active component of the product is considered to be aluminum phosphide. 1 kilogram of the composition contains 560 grams of this ingredient.
Purpose and principle of operation
"Fumifos" releases a special gas - phosphine. The substance enters the body of parasites through the respiratory organs and stops the movement of electrons. This occurs in the fourth mitochondrial complex.
The rapid absorption 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 phosphine. This applies to the egg, pupal and larval stages of diapause. At the same time, the imago and active stages of larvae are more susceptible to the effects of the drug.
The key advantages of Fumifos include the following:
- the use of the substance does not provoke a deterioration in the quality parameters of grains and their germination;
- the composition is easy to use - phosphine gas easily penetrates into any packaging;
- the substance helps to quickly carry out high-quality and complete processing;
- the composition is completely harmless if the instructions for its use are followed;
- the substance has high fumigation activity.
Instructions for use and dosage
When processing grain in elevator silos, Fumiphos tablets must be administered using a special dispenser. The bunker needs to be filled in a short time.
If grains are processed in warehouses, the tablets must be distributed throughout the grain mass using special probes. When fumigating small batches of grains or processing bagged products, the product is placed throughout the facility.
Specific dosages are indicated in the table:
| Application rate | Culture | Pests | Processing Features |
| 5 grams per 1 cubic meter | Unloaded granaries | Harmful insects, excluding ticks | Processing must be carried out at temperature parameters greater than +15 degrees. The exposure period is 5 days. It is permissible to load the storage and admit people only after ventilation. In this case, the volume of phosphine in the air should not exceed the maximum permissible concentration. |
| 9 grams per 1 ton | Food and seed grains, bulk feed in warehouses, bagged stocks, small quantities weighing no more than 200 tons | Harmful insects, excluding ticks | Processing grains is required at temperatures above +15 degrees. The duration of exposure is 5 days. Degassing should take at least 10 days. People are allowed into the premises only after ventilation. In this case, the level of phosphine in the air should not exceed the maximum permissible concentration. |
| 6 grams per 1 cubic meter | Different types of grain reserves in ship holds with an embankment of 4-6 meters | Harmful insects, excluding ticks | Grain must be processed at temperatures above +15 degrees. Place the tablets in grain to a depth of 2 meters. It is recommended to use special gas-permeable capsules. The exhibition lasts 3 days. The degassing period is at least 8 days. |
Precautionary measures
"Fumifos" is a drug for limited use. If it enters the digestive or respiratory organs, the product poses a real danger. Even a diluted volume of gas in the air in open areas poses a danger to the environment.
Storage of the drug "Fumifos"
The composition must be stored in warehouses that are used for pesticides. In this case, it is recommended to use sealed original packaging. The temperature range can be from -10 to +30 degrees. The shelf life in original packaging is 2 years.
