Phosphine Tolerance Test
Inadequate fumigation practices lead to the development of tolerances. The reasons for this are too low dosages, too short exposure times, bad sealing of the fumigated venue and fumigation at too low temperatures.
The Phosphine Tolerance Test enables the user to gain information about resistances sensitivity of insect strains against phosphine gas. This information helps to adjust dosages, exposure times in order to control insects properly.
The kit is packed in a 54 x 35 x 27 cm carton
- 100 ml syringe
- 2 cannulas (1 cannula with a rubber hose)
- 5 l flexible plastic canister
- Lid with septum
- 5 x 2 Test Kit Pellets (8 % Magnesium Phosphide) packed in aluminium pouches
- Diagram and table to determine the dilution
- Instructions for use
Mode of action
The Phosphine Tolerance Test is intended for testing the behavior and the activity of insect pests in a defined phosphine-containing atmosphere. It is a very easy-to-use field test, which can be applied within a very short period on site.
What to do if the suspicion of tolerance is corroborated?
If tolerant insects are detected during the test, the following fumigation shall be conducted considering the following rules:
- Do not fumigate at a temperature below 10°C.
- Check the sealing of the whole structure to be fumigated
- Extent the exposure time to the maximum possible under gastight condition.
- Monitor the gas concentration during the whole fumigation process.
- If necessary increase the dosage gradually according to the local product registration.

Phosphine is also highly toxic to humans and warm-blooded animals. It is therefore absolutely necessary to comply with the relevant safety measures.
