Questions with Detailed Verified Answers
Abiotic disorder
⼀Answer:- A non-pest plant stress such as improper nutrition, too
much or too little water, winter or frost injury
Action threshold
⼀Answer:- The pest density at which action (such as pesticide
application) is justified to prevent further damage.
Adelgid
⼀Answer:- An insect closely related to aphids that feed on conifers.
Their feeding often causes galls to form.
Aesthetic injury level
⼀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
⼀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
, Page | 2
⼀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.
Annual
⼀Answer:- A plant that completes its life cycle and dies in a single
year or growing season.
Bacteria
⼀Answer:- A group of single-celled microorganisms, of which there
are typically 40 million in a gram of soil. A few species are the causes
of diseases such as fire blight and leaf spot in plants.
Bactericide
⼀Answer:- A pesticide used to manage a disease cause by bacteria
Balled and burlapped
⼀Answer:- A standard method used to wrap a tree or 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.
Basal Drench
, Page | 3
⼀Answer:- The mixing of a pesticide in a small volume of water and
applying to a 12-18 inch strip around the base of a tree or shrub.
These compounds are normally systemic and are absorbed by the
roots of the plant.
Beauveria bassiana
⼀Answer:- A naturally occurring fungus that attacks a number of
insects and has been formulated as an insecticide.
Beneficial Insect
⼀Answer:- Insects that eat or develop inside or on pest insects.
Sometimes just referred to as "beneficials." Beneficial insects do not
damage landscape plants.
Biennial
⼀Answer:- A plant with a two-year life cycle.
Biochemical pesticide
⼀Answer:- A biologically derived chemical such as insect sex
pheromones that are used for pest control. They have the advantages
of being non-toxic and specific for controlling a particular species of
pest.
Biocide
⼀Answer:- A substance that kills biological organisms.
Biological control
, Page | 4
⼀Answer:- A method of controlling a pest by encouraging and using
natural controls such as parasitism, predation, and naturally occuring
diseases.
Biomagnification
⼀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
⼀Answer:- Pesticides cerived from natural materials such as animals,
plants, bacteria and certain minerals.
Broad-spectrum
⼀Answer:- A pesticde that affectsx a wide range of target species.
Broad-spectrum fungicide
⼀Answer:- A fingicide that controls a wide range of fungal
organisms.
Broadcast application
⼀Answer:- A pesticide applied to a large area over all of the
plants.
Budbreak
⼀Answer:- The timme when dormant buds open into leaves or
flowers.
