CORECT ANSWERS!!
Specifically designed structure used to conduct a fumigation where the air can be removed
prior to introducing the fumigant
Vacuum chamber
The pressure exerted by a liquid or solid as it volatilizes
Vapor pressure
Very small organism that multiplies inside living cells and is capable of producing disease
symptoms in some plants and animals
Virus
A substance that vaporizes readily. That means it changes from a liquid, or even a solid
into the gas phase
Volatile
The upper level of a ground water reservoir or aquifer
Water table
A type of pesticide formulation consisting of an active ingredient that will not dissolve in
water combined with a mineral clay or other inert ingredients and ground into a fine
powder
Wettable powder
In wood, any decay or rot that attacks both the cellulose and lignin and produces a
generally whitish residue, which may be spongy or stringy. Also may occur as pocket rot.

A type of monitor that uses infrared light to detect and measure gas fumigant
concentrations- also called "IR analyzer"
Ambient air analyzer
A type of wood destroying fungi that remove cellulose leaving wood darkened and
fractured
Brown rot
Chamber fumigation
The use of a well sealed structure to conduct a fumigation. some chambers are specifically built
for fumigation while others are modified rooms or buildings
