Technical Requirements:

This product should be used by professional technicians familiar with its use and safety precautions. Apply the pesticide in a layered, multi-point, evenly distributed manner. Apply 2/3 of the total pesticide dose in the top layer, and 1/3 in the middle layer. For bulk grain, use a probe for middle-layer application. For packaged grain, divide the tablets into small packages of 5-10 tablets. Apply the tablets 1-1.5 meters apart and to a depth of 1 meter. Sealing time: This varies depending on the temperature; at temperatures between 12-20°C, it should be 7-5 days. Allow disposal of residues after 3 days of air release. No one is allowed to enter during application, and a warning sign should be posted in a prominent location.

Product Performance:

This product is made of aluminum phosphide and other auxiliary materials in tablet form. It is gray-green in color and contains≥56% aluminum phosphide. When exposed to moisture in the air, the tablets decompose into toxic phosphine gas (with a garlicky odor and a specific gravity of 1.183). Phosphine gas enters the insect's respiratory system and acts on the mitochondrial respiratory chain and cytochrome oxidase, inhibiting the insect's normal respiration and killing it. It can be used to fumigate stored-grain pests in grain and seeds.
