ing, pulling, or carrying the application equipment and the pesticide. Two
related factors also apply. The motion of the vehicle creates the effect of wind
on the applicator with the concomitant cooling effect. Secondly, the vehicle
is often equipped with a cab, awning, or other over-head shield that shades the
applicator from the full force of the sun's intensity.

Airblast/mistblower applications, unless performed while in an enclosed
cab, are likely to expose the pesticide applicator to large quantities of drifting
"mist," often to the point of being completely drenched in the pesticide fall-
out. Such exposure cannot be avoided, even if the application is performed in
conditions of little or no wind and care is taken to remain out of the direct path
of the air blast.

By Air
Agricultural pesticide users who apply pesticides from aircraft are also
usually distanced from the pesticide being applied. The dispersal of the pesti-
cide is from below the aircraft, and gravity and the speed of the aircraft carry
the pesticide rapidly away from the cockpit
