Fumigation is a pest control method that uses toxic gases to eliminate pests, termites, and other harmful organisms. It involves suffocating or poisoning the pests within a specified area using fumigants. It is used in various applications such as structural fumigation, soil fumigation, and food commodity fumigation, as well as in the processing of import/export goods to prevent the spread of exotic organisms. Fumigation also eliminates pests that inhabit physical structures, such as wood borers and dry wood termites.
Fumigation is necessary to prevent damage to commodities caused by insects, weeds, and other pests.
Methyl Bromide (MBR) is a fumigant used in soil to control fungi, nematodes, and weeds. It is also used in the fumigation of food commodities (e.g., grains) and in storage facilities such as mills, warehouses, vaults, ships, and freight cars to control insects and rodents. In various industries, Methyl Bromide can also be used as a chemical intermediate, methylating agent, refrigerant, herbicide, fire extinguishing agent, and solvent.
Aluminium Phosphide (ALP) is used as a rodenticide, insecticide, and fumigant for stored cereal grains. It is used to kill small verminous mammals such as moles and rodents. The tablets or pellets, known as “wheat pills,” typically also contain other chemicals that evolve ammonia which help to reduce the potential for spontaneous ignition or explosion of the phosphine gas.
Zinc Phosphide is a chemical commonly used to control rodents in various crops such as grapes, sugarcane, artichoke, sugar beet, alfalfa, barley, berries, oats, sugar maple, wheat, corn, and hay. It can also be used on non-crop areas such as lawns, golf courses, highway medians, and areas adjacent to wetlands.
Before fumigating a container, it is essential to determine if the container complies with the specified pressure test standard for gas-tightness. This can be done through a pressure decay test. This corresponds to a pressure halving (or decay) time from 200-100 Pa of 10 seconds or more. If a container cannot be pressurized to 250 Pa, it is deemed to have failed the test and must be enclosed under gas-proof sheets before being fumigated with Methyl Bromide or the chosen fumigant. This process must be repeated every time the container is used to ensure its cleanliness and to prevent the transfer of exotic organisms.
The length of time required for fumigation varies from six hours to one week, depending on various factors like the type of infestation, dosage, temperature, and structure size.
Methyl Bromide (MBR): CH3Br
Aluminium Phosphide (ALP): AlP
Yes, there are several important instructions to follow while using Methyl Bromide and Aluminum Phosphide:
Methyl Bromide is highly toxic and can be harmful to humans and animals if not handled properly. If inhaled or absorbed through the skin, acute exposure can cause severe chemical burns to the skin, eyes, and airways. It can also cause delayed chemical pneumonia, producing water in the lungs, severe kidney damage, and devastating effects on the central nervous system. In some cases, exposure to Methyl Bromide can even be fatal.
The most widely used form of Methyl Bromide across the globe is 98% MBR mixed with 2% Chloropicrin. Since MBR is odorless, Chloropicrin acts as a warning agent and helps detect its presence in the area.
Fumigation is a hazardous operation. Hence, only licensed and trained professionals who hold official certification should fumigate with MBR and ALP, as they are toxic chemicals that can cause harm to humans, animals, and the environment if not handled correctly.
