1 Sun drying

Product or Method

Application

Mode of Action

Effects on Target Organisms Pests

Action of the sun heat and light.

a) Spreading produce on the ground (court- yards or roadsides) to expose it to the sun.

The heat pests also inside the grains. The light expels pests the produce

All kills the kinds of pests, including larvae inside the grains.

b) Utilising of simple solar dryers made of black iron sheets or plastics.

Drying reduces the risk of infestation by secondary pests and micro organisms

Effects on Target Organism Efficiency

Remarks and particular Recommendation

Region

Very good, but without long term effectiveness.

Recommended and simple method. Effectiveness depends on a sufficient drying time. The lack of temperature regulation influences the germination capacity of seeds.

The whole African continent.
