pesticide application) is justified to prevent further damage.
Adelgid - correct answer. An insect closely related to aphids that feed on conifers.
Their feeding often causes galls to form.
Aesthetic injury level - correct answer. The point at which damage from a pest
becomes noticeable enough to negatively affect the visible quality of the plant. This may
vary, based in part on the distance the plant is located from walkways. (and therefore,
on the likelihood of the damage being observed.
Airblast sprayer - correct answer. Pesticide application equipment that uses a
stream of air from a fan to break up and distribute the pesicide onto the plant that is
being treated.
Allelopathy/allelopathic - correct answer. When one plant species suppresses the
growth of another. For example, walnut trees produce chemicals that will not allow
plants to grow under their canopies.

shrub rootball with burlap to keep the soil around the roots when digging the plant from
the field to move it for transplanting. Often, larger trees will have a wire mesh placed
around the burlap to provide more support for transporting. The wire mesh should be
removed prior to planting. The burlap should (optimally) be removed as much as
possible also, as amany types of modern burlap contains synthetic fibers that will not
rot. If the burlap is natural fibers it should at least be removed from the top one-third of
the rootball to avoid the burlap being exposed to the air and wicking moisture from the
roots. Also called B&B.

Biocide - correct answer. A substance that kills biological organisms.
Biological control - correct answer. A method of controlling a pest by encouraging
and using natural controls such as parasitism, predation, and naturally occuring
diseases.
Biomagnification - correct answer. A situation in which a predatory organism
continues to absorb pesticde as it eats prey that has been exposed to nonlethal levels
of pesticide; the accumulation of pesticide in the predator can lead to its death.
Biopesticide - correct answer. Pesticides cerived from natural materials such as

Chlorotic - correct answer. When the leaves of a plant exhibit yellowing.
Cold temerature hardiness - correct answer. The ability of a plant to withstand the
extremes of temperature during the winter for a particular area of the country. The U.S.
Department of Agriculture has developed zone maps to indicate parts of the country that
are subject to roughly the same extremes of cold temperatures. Plants are rated as to
the hardiness zones in which they are able to survive.
Commercial applicator - correct answer. A person who has been certified by the
State of Michigan to apply pesticides for hire. In Michigan, any individual who is
applying pesticides for hire on property they do not own and where they are not being
supervised by the property owner of the owner's representative (such as on a farm or
