Aluminium phosphide tablets are gray-black solids with white spots, and the appearance of the powder is gray-green. The product easily absorbs moisture in the air and separates out highly toxic and highly toxic phosphine gas. Each gram of aluminium phosphide tablet can produce about 1 gram of phosphine gas. When the air contains 0.01 mg of phosphine, it will be harmful to pests. It has a lethal effect. It is widely used for fumigating pests in food, seeds, medicinal materials, feed, tobacco and other items. It can also be used for fumigation in silos, warehouses, containers, factories, storage rooms, railway cars, trucks, ships and other spaces Killing insects and rodents.
Fumigating aluminium phosphide in warehouses and tabernacles to prevent various stored grain pests and mites, but can not poison dormant mites. It has a wide range of applications and is not affected by temperature. It can fumigate raw grain and finished grain, as well as fumigate crop seeds and various storage equipment. Phosphine gas is very easy to diffuse in the air, and the warehouse after fumigation can generally be dispersed within 24 to 28 hours, without affecting the color, taste and food hygiene of the food. For the fumigated seeds, the germination rate is not affected within the prescribed dose and the number of closed days. It is also used to fumigate rodents in the field and warehouse. The time of smoking seeds should be shorter, so as not to affect the germination of seeds. After the fumigation is over and the air is ventilated for 5 to 6 days, the toxic gas can completely disappear. The remaining small amount of residue is non-toxic aluminum hydroxide and does not need to be removed. Aluminium phosphide is most suitable for food and commodities with a long storage period. Due to the long time required to exert the drug effect, it is generally not used for quarantine emergency treatment. Open air tent fumigation. Generally calculated as 10-12 tablets per ton of medicine. In the open air, put the pills on the surface of the grain pile, or put them in a bamboo trough at the bottom, covered with a plastic tent. If there is a lot of grain in bags, place the tablets in the gap between the stacked grain bags, or insert 1 piece of medicine per 100 kilograms of grain in the grain, and then cover it with a tent. The area around the ground that is in contact with the ground should be compacted with masonry , Or use mud to tighten. Fumigation time is the same as warehouse fumigation. Rodent. The use of aluminium phosphide rodenticide is a feature that the generated phosphine gas is more important than air. The gas can penetrate deep into the burrows and nests of rats, and it can often get twice the result with half the effort for rats in a multi-hole or lactation stage. Generally, 0.5 to 1 tablet per hole is used. If the mouse hole is large and the hole is more, one tablet can be added. Use a small spoon to put the pills into the hole and block the hole with soil. For example, after the tablet is put into the mouse hole, a small amount of water is added, so that the tablet can be quickly separated into phosphine.
