Celphos Mode of Action
Celphos, a fumigant insecticide, works by releasing phosphine gas. This gas is inhaled by insects and disrupts their cellular respiration, leading to their death. It’s primarily used for controlling stored product pests in various commodities and is known for its effectiveness, ease of use, and lack of residual effects on treated items.
Celphos is an insecticide that acts by contact, ingestion, and especially inhalation. It blocks the breathing of insects, causing death very quickly. Celphos comes in the form of a tablet, which metabolizes into gas when the packaging is opened, making it possible to treat even hard-to-reach volumes. Precautions for use: open the packaging with caution while being equipped with the appropriate protective equipment.
Advantages of Celphos

Benefits of Celphos
- Phosphine gas from Celphos is practically insoluble in water, fats, and oils and therefore has no appreciable reaction on the fumigated commodities.
- Phosphine gas disappears completely after fumigation from the treated area upon aeration.
- Phosphine from Celphos does not adversely affect the quality of agricultural commodities fumigated.
- It is rapidly deactivated by photolysis (effect of sunlight).
- Easy to use, economical, and highly effective fumigant.
- Eliminates all pests from stored foodstuffs
- No residual effect on treated foodstuffs
- Can be used at very low doses
- Product dedicated to fumigation professionals

- Following fumigation, there should be an airing-off period of at least four hours or until gas levels drop below the Occupational Exposure Standard.
- Once opened, the contents of the container must be used immediately.
- Unprotected persons must be kept out of treated areas until the phosphine concentration in the atmosphere has fallen below the Occupational Exposure Standard.
- After following the appropriate exposure times, the following minimum airing periods must be observed:
1. Rice, wheat, barley, maize, oats, sorghum, rye, millet, and oilseeds – four hours
2. Animal feed, flour, spices, confectionery, biscuits, dried fruit and nuts, and tobacco in cases or bales – two days.

- IN CASE OF FIRE. Use dry sand, powder, or CO2. Never use Water.
- Remains of containers must be removed after treatment and buried. All persons and animals must be kept out of the fumigation area and adjacent areas into which gas might penetrate.
- Do not use when the commodity temperature is below 15 °C and/or the relative humidity within the structure is high, or with row cereal grain, the moisture content should be less than 9%.
- Don’t fumigate in inhabited buildings.
- Don’t use on any commodity, empty containers, or vessels that are in transit.
- Don’t heap tablets.
- Don’t apply as a surface-only treatment in a structure whose height exceeds twice its width.
