Biological control (Biocontrol)
Pest control strategy making use of living natural enemies, antagonists, or competitors and other self-replicating biotic entities (IPPC, 2004).
Biological control agent
A natural enemy, antagonist or competitor, and other self-replicating biotic entity used for pest control (IPPC, 2004).
Biological safety cabinet (BSC)
A primary containment device that provides protection for personnel, the environment, and, in some cases, products from airborne or aerosolized microorganisms. BSCs consist of a leak-tight box, HEPA filter(s) and a motor/blower system to provide controlled air movement through the box and filters.
Containment
Restricting plant pests to their intended locations through the use of operational procedures, physical barriers and facility design.
Containment facility
A structure whose purpose is to prevent escape of material held within it, into the environment (NAPPO 2005).
Containment perimeter
The continuous floor, ceiling and wall surfaces that form a barrier against the ingress or egress of plant pests including all windows, doors and service penetrations into the area.
Containment zone
A contiguous physical area within a physical structure that meets specified containment requirements.
Decontaminate
To render a plant pest non-viable.
Facility
Laboratories, greenhouses, screenhouses, growth chambers and other supporting structures and buildings.
Greenhouse
A structure with a floor and transparent walls and roof designed and used principally for growing plants in a controlled and protected environment.
Growth chamber
A mechanical device designed to provide a suitable environment for growing plants under controlled light and temperature conditions.
Growth room
A structure with walls, a roof and a floor designed and used principally for growing plants or other organisms in a controlled and protected environment (VLAREM II 2005).
A building connected to one or more greenhouses that may include laboratories, offices, storage and greenhouse support areas.
HEPA filter
High Efficiency Particulate Air filters with a minimum efficiency of 99.97% at 0.3 µm.
Inward directional airflow
Airflow created by a ventilation system such that air will always flow to areas of higher risk of contamination (e.g. 12.5 - 25 Pa differential).
Kneewall
A partial-height solid wall in a greenhouse that is placed to minimize the possibility of glass breakage.
NAPPO
North American Plant Protection Organization
Pass-box
A sealed box with two doors constructed through and sealed to the containment perimeter. The box is equipped with interlocking doors (preferred), or audible or visual alarms to prevent or deter, the simultaneous opening of both doors.
Plant pest
Any thing that is injurious or potentially injurious, whether directly or indirectly, to plants or to products or by-products of plants, and includes any plant prescribed as a pest [PPA 1990]. This includes any species, strain or biotype of plant, animal or pathogenic agent injurious to plants or plant products (IPPC 2004) including, but not limited to, arthropods, molluscs, bacteria, nematodes, fungi, phytoplasmas, viruses and viroids.
Primary containment
The protection of hosts within the containment zone from exposure to plant pests. Primary containment is achieved through the use of good microbiological techniques that prevent the release of pests into the zone and through the use of appropriate primary containment devices such as BSCs and insect cages.
Program change
A change in a PPC-3 facility that relates to the nature of work or the procedures employed and that would increase the risk of pest escape from the facility.
Screenhouse
A structure with a roof, floor and screened walls, designed and used principally for growing plants in a protected environment.
Secondary containment
The protection of hosts outside the containment zone from exposure to plant pests. Secondary containment is provided by the resistance of the containment zone to the active or passive movement of pests combined with good operational practices.
