Product or

Application

Mode of Action

Effects on Target

Method

Organisms Pests

Produce stored in airtight structures.

Storing in pits or containers, like barrels, hermetically sealed to reduce oxygen concentration and simultaneously increase the concentration of carbon dioxide (respiration of cereals).

Death of pests after some days due to a lack of oxygen and intoxication from carbon dioxide.

All kinds of pests, including mites and larvae inside the grains.

Effects on Target Organism Efficiency

Remarks and particular Recommendation

Region

Very good. The storage atmosphere becomes lethal after 2 - 3 weeks and the pests die. Ovicide effects.

Storage is possible only in very dry areas. Store only well dried produce! Containers stored above ground must be completely protected by shadow to avoid the condensation of water and mould growth. Avoid frequent opening of containers. Therefore, separate the produce for short term consumption from the produce for long term storage.

Arid and semi-arid regions of North-east Africa.
