First, the product features. Aluminum phosphide is a broad-spectrum fumigation insecticide used primarily for fumigation of various warehouse pests and for rodent control in warehouses. When aluminum absorbing air absorbs air, it immediately produces highly toxic phosphine gas, which enters the worm body through the respiratory system of insects (or animals such as mice) and inhibits the normal growth of insects.
Second, the scope of application. In sealed warehouses or containers, all kinds of stored grain pests can be directly eliminated, especially in the mushroom room. The control effect on rice, valley and whitefly is very prominent. And can kill the mice in the warehouse, the granaries have appeared pests, but also can kill well. In the sericulture area, there is no need to dry it again. In the case of a thick plastic bag in a warehouse or texture, the silkworm cocoons can be directly killed. Phosphine can also be used for mites, mites, leather garments, downy worms, or pests in households and stores. It can be used in sealed greenhouses, glass houses and plastic greenhouses to directly kill all underground and above-ground pests and rats, and penetrate into plants to kill drill-bit pests and root-baseworms. Use thicker sealed plastic bags and greenhouses to handle open flower bases and export potted flowers to kill all kinds of pests on the nematodes and plants in the ground and in the plants.
Third, the use of methods and precautions:
1. Use in sealed warehouses and greenhouses. For example, if there is no deposit and crop growth, each tablet can be used for two or three cubic meters of space; if there are deposits, each tablet can be used for 1 cubic meter of space. For bonsai, flowers and clothing, de-worming, put a tablet in each plastic bag (tighten the pocket seal). When used in clothes, wrap the tablets in toilet paper to avoid contamination of clothing, items, etc. It must be used under completely sealed conditions and taped to all the leaking holes to ensure the control effect.
2. After absorbing aluminum, the aluminum phosphide will release toxic gas immediately. After the application is completed, people and animals must leave the site immediately, and after 48 hours, open the warehouse, greenhouse, and plastic bag to ventilate the toxic gas. Ensure the safety of people and animals.
3. The aluminum phosphide tablets should be sealed, protected from light and stored in moisture. Once the tablet is loose, it has failed. Do not let children touch, and the residual tablets are buried in the soil immediately after use. (Lü Lafu)
Right-angle prism is the most common type of prisms. It is used to re-direct a beam of light at 90 degrees from the the incident direction or used as a 180 beam retro-reflector. They are often coated with various optical coatings to form cubic beam splitters and color separation cubes used in various projection systems.
