III. SOIL FUMIGATION EQUIPMENT
The equipment needed for applying soil fumigants depends on the kind of
fumigant being used. There are two types of fumigants:
low-pressure (low volatility) liquid fumigants
highly volatile fumigants which remain as liquids only when placed under
pressure.
A. LOW-PRESSURE LIQUID FUMIGATORS
Equipment for applying low-pressure fumigants is widely varied but uses
two basic designs for delivering the amount of fumigant to be metered out.
These delivery systems are either pressure (pump)-fed or gravity-fed.
Pressure-fed applicators have a pump and metering device and deliver
fumigant at pressure to the nozzle openings (orifices) as with a low-pressure
sprayer.
