Comparison of Indoor Residual Spray Equipment for Malaria Control in Liberia.

We describe and compare a new innovative backpack compressed-air sprayer (JQSX-12) to a Stihl (R) 450 backpack mist blower and a manually operated compression sprayer for its effectiveness as an alternative operational tool for indoor residual insecticide application to control malaria in Liberia. Advantages and physical characteristics of each sprayer and their spray atomization parameters are discussed.
