 Application In the sealed warehouse or container, it can directly kill all kinds of stored grain pests and rats in the warehouse. If there are pests in the granary, it can also be well killed. Phosphine can also be used when mites, lice, leather clothes and down insects of household and store items are eaten, or pests are avoided. When used in sealed greenhouses, glass houses and plastic greenhouses, it can directly kill all underground and aboveground pests and mice, and penetrate into plants to kill boring pests and root nematodes. Sealed plastic bags and greenhouses with thick texture can be used to deal with open flower bases and export potted flowers, and kill nematodes underground and in plants and various pests on plants. Dosage and usage 1. 3 ~ 8 pieces per ton of stored grain or goods; 2 ~ 5 pieces per cubic meter; 1-4 pieces per cubic meter of fumigation space. 2. After steaming, open the curtain or plastic film, open the doors and windows or ventilation gate, and use natural or mechanical ventilation to fully disperse the gas and exhaust the toxic gas. 3. When entering the warehouse, use the test paper soaked in 5% ~ 10% silver nitrate solution to test the toxic gas. Only when there is no phosphine gas can it enter the warehouse. 4. The fumigation time depends on the temperature and humidity. Fumigation is not suitable below 5 ℃; 5 ℃ ~ 9 ℃ for no less than 14 days; 10 ℃ ~ 16 ℃ for no less than 7 days; 16 ℃ ~ 25 ℃ for no less than 4 days; Not less than 3 days above 25 ℃. Smoke and kill voles, 1 ~ 2 tablets per rat hole. Features and effect 1. Direct contact with the reagent is strictly prohibited. 2. The use of this agent should strictly abide by the relevant regulations and safety measures of aluminum phosphide fumigation. The fumigation of this agent must be guided by skilled technicians or experienced staff. It is strictly prohibited to work alone. It should be carried out in sunny weather, not at night. 3. The medicine barrel shall be opened outdoors. A danger warning line shall be set around the fumigation place. The eyes and face shall not be directly facing the barrel mouth. The medicine shall be administered for 24 hours, and a special person shall be assigned to check whether there is air leakage and fire. 4. Phosphine is highly corrosive to copper. Copper parts such as electric lamp switch and lamp cap are coated with engine oil or sealed and protected with plastic film. Metal devices in fumigation places can be removed temporarily. 5. After dispersing the gas, collect the residue of the medicine bag in full. In the open place far away from the living area, put the residue bag into the steel bucket containing water and soak it fully, so that the residual aluminum phosphide can be completely decomposed (until there is no bubble on the liquid surface). The harmless slag slurry can be discarded in the waste slag discharge site allowed by the environmental protection management department. 6. Treatment of phosphine absorbent bag: after the flexible packaging bag is unpacked, a small absorbent bag attached to the bag shall be collected and buried in the field. 7. Used empty containers should not be used for other purposes and should be destroyed in time. 8. This product is toxic to bees, fish and silkworm.
