(2) Remote control assembly -- allows operator to operate PDU from inside
Hydraulic reservoir -- provides supply of hydraulic fluid for system.
Gas tank -- provides fuel for the engine.
Engine -- provides power to drive main hydraulic pump.
(6) Pump and crosstube assembly -- provides hydraulic pressure for
operation of LV and ULV systems.
(7) LV boom assembly -- provides LV dispersal of liquid pesticides where
minimum penetration is acceptable (sparse foliage). Transports liquid pesticide from
hopper to nozzles and provides attachment sites for up to 34 nozzles.
(8) ULV boom assembly -- provides ULV dispersal liquid pesticides where
maximum penetration is needed (dense foliage). Provides attachment of two
hydraulically actuated rotary atomizers.
(9) Slinger assembly -- provides for dispersal of granular pesticides by
(10) Left and right hopper assemblies -- control solid pesticide dispersal
through flow metering plates and hydraulically actuated gates.
(11) Battery -- provides electrical power to starter.
3-7. ARMY POLICY ON AERIAL DISPERSAL
The Department of the Army requires the filing of an Environmental Impact
Statement (EIS) whenever there is to be an aerial dispersal of pesticides. Considering
the hazards involved in such an operation (i.e., the inadvertent poisoning of nontarget
organisms and low-level flying), aerial dispersal is used only when other methods are
impractical. Military agencies must justify aerial dispersal of pesticides in terms of
necessity on an epidemiological basis, having also shown its economy over other
