Phosphine

Phosphine (hydrogen phosphorus, PH₃) is a colorless, toxic gas with a characteristic smell of rotten fish or garlic. It is used as an effective fumigant for pest control in closed spaces.

Phosphine Uses:

• Destruction of collar pests in stored grain, in silos, elevators and chutes
• Mill treatment (gassing)

• High efficiency against a wide range of pests
• Does not leave toxic residues in products
• Penetrates into hard-to-reach places

Fumigation

Fumigation (from Latin fumigatio — fumigation) — a method of combating pests of grain and grain products. Fumigation is carried out using toxic gas, which is released by special substances — fumigants. Fumigation creates a poisonous environment around the object, which contributes to the destruction of pests.

Fumigation carry out:

• In warehouses for floor storage - necessarily with film covering
• In silos of elevators (metal and concrete)
• In sleeves for grain storage

• Gas fumigants - fill the space, entering the object through special devices
• Smoke fumigation - is carried out by burning fumigants in special devices or using smoke bombs

• Warehouses, greenhouses, elevators, vehicles
• Plant products (grain, fruits, vegetables, seeds, planting material)
• Vegetating plants (vineyards, citrus trees)
• Soil and rodent burrows

Aerosol treatment equipment

Aerosol treatment equipment:

• Hot and cold fog generators that spray insecticide solutions in the form of an aerosol
• Gas analyzers monitor the concentration of substances in the air
• Hot fog — spraying high-temperature aerosols (5 - 50 microns) using fog generators
• Cold fog — spraying room-temperature aerosols (100 - 150 microns) using fog generators

Gasification

Gasification is the old name for fumigation and aerosol disinfestation.

Disinsection

Disinsection (from French des — removal and Latin insectum — insect) — a set of measures to combat harmful insects and mites.

Disinsection is carried out to destroy:

• Insects that harm grain, food, and fodder stocks
• Parasites in storage facilities

Deratation

Deratation is a set of measures aimed at destruction and prevention of rodents using special poisonous substances (rodenticides).

Methods of deratization:

• Mechanical - traps, traps, trapping
• Biological - use of natural enemies (cats, predators)
• Chemical - use of rodenticides (poisons)
• Electronic - ultrasonic type repellers

Regulations and standards

Regulations and standards of fumigation works are regulated by the legislation of Ukraine and international standards.

Main regulatory documents:

• State sanitary rules and regulations
• International phytosanitary requirements
• Rules for the transportation and storage of chemicals

Frequently asked questions

❓ Is fumigation safe?
✅ Yes, provided that all safety rules and regulations are followed.

❓ How long does the treatment last?
✅ Depends on the object and type of fumigation (from several hours to several days).

❓ Is it possible to stay indoors after fumigation?
✅ No, you must withstand the airing time and check the level of residual substances.
