Description: Caption:
The man pictured in this 1965 photograph, was in the process of dispersing an airborne insecticide, using a machine known as a thermofog applicator. The fog of chemicals was being applied in what is known as an ultra-low volume (ULV) method. In this case, the insecticide was added to the reservoir atop the machine, and the operator would push the unit across the ground within the area to be treated. Note the operator was shown here, holding the hose, which was equipped with a spray nozzle, from which an insecticidal cloud of was being emitted. After being sprayed from the nozzle, the chemicals would then indiscriminately settle out unto objects in the vicinity, or on the ground and surrounding plant life.
