SPRAYER SELECTION, USE, AND CARE
Choosing the correct sprayer for each job is important. Your sprayer
should be:
•
designed to do the job
•
durable
•
convenient to fill, operate, and clean.
Always read and follow the operator's manuals for all your spray equip-
ment. They will tell you exactly how to use and care for it. After each use,
rinse out the entire system. Check for leaks in lines valves, seals, and tank.
Remove and clean nozzles. Nozzle, screens, and strainers.
Be alert for nozzle clogging and changes in nozzle patterns. If nozzles
clog or other trouble occurs in the field, be careful not to contaminate yourself
while correcting the problem. Shut off the sprayer and move it to the edge of
the field before dismounting. Wear protective clothing while making repairs.
Clean plugged nozzles only with a toothbrush or wooden toothpick or similar
instrument. Never use your mouth.
To prepare spray equipment for storage, rinse and clean the system. Then
fill the tank almost full with clean water. Add a small amount of new light
oil to the tank
.
Coat the system by pumping this mixture out through the
nozzles or handgun. Drain the pump and plug its openings or fill the pump
with light oil or antifreeze. Remove nozzles and nozzle screens and store in
light oil or diesel fuel.
II. AEROSOL GENERATORS AND FOGGERS
Aerosol generators and foggers convert special formulations into very
small, fine droplets. Single droplets cannot be seen, but large numbers of
droplets are visible as a fog or mist. Aerosol generators and foggers are usu-
ally used to completely fill a space with a pesticidal fog. Some insects in the
treated area are killed when they come in contact with the poison. Other insects
are
simply repelled by the mist and return quickly after it has settled.
Thermal foggers, also called thermal generators, use heat to vaporize a special
oil formulation of a pesticide. As the pesticide vapor is released into the
