3B Turf Pest Control Key Terms UPDATED
ACTUAL Exam Questions and CORECT
Answers
Calibrate - CORRECT ANSWER -To measure the delivery rate and distribution of
application equipment; to adjust application equipment so the desired amount of pesticide is
applied evenly to a given area.
Disease - CORRECT ANSWER -An abnormal, unhealthy condition. Turf diseases may be
caused by abiotic or biotic factors. However, they are typically due to infectious organisms such
as bacteria, fungi, and viruses.
Exclusion - CORRECT ANSWER -Using some sort of barrier to keep a pest out of an
area.
Exposure - CORRECT ANSWER -Coming in contact with a pesticide either by ingestion
(oral), inhalation, or absorption through the skin (dermal).
Habitat - CORRECT ANSWER -A specific area or environment in which an organism
normally lives.
Insect - CORRECT ANSWER -An arthropod with three body regions: a head (front), a
thorax (middle), and an abdomen (rear). Most insects have one pair of antennae on the head, two
pairs of Wings, and three pairs of legs on the thorax. Most have complex mouthparts adapted for
a special type of feeding.
Integrated Pest Management (IPM) - CORRECT ANSWER -VA management system that
uses all appropriate pest control strategies to reduce pest populations to an acceptable level. IPM
uses an ecological approach to pest management.
,Life Cycle - CORRECT ANSWER -An 0rganism's progression through developmental
stages. As some organisms go through their life cycle, they change in body form and habits.
Mite - CORRECT ANSWER -A small arachnid with eight legs in the adult stage. Mites
have a single body region, which seems to lack segmentation. Some mites are plant pests.
Mollusk - CORRECT ANSWER -A soft-bodied animal. A mollusk does not have a
backbone. Mollusks have a hard calcium-based shell covering its body. Clams, snails, and slugs
are mollusks.
Monitoring - CORRECT ANSWER -The process of assessing-"keeping tabs on"—the size
and distribution of a pest population in an area.
Natural Controls - CORRECT ANSWER -Natural forces that affect pest populations.
Examples include climate, natural enemies, natural barriers, and the availability of food, water,
and shelter. These natural forces act independently and may either help or hinder human attempts
to control pests.
Nematode - CORRECT ANSWER -A small, unsegmented roundworm. Most nematodes
are so small that they cannot be seen with the naked eye.
Leaching - CORRECT ANSWER -Movement of a substance (such as a pesticide) in
solution downward through soil.
Nematicide - CORRECT ANSWER -A pesticide that controls nematodes.
Parasite - CORRECT ANSWER -An organism that obtains its food from another living
thing, and in so doing, harms that organism (its host). The disease organism is the parasite, and
the infected organism is the host.
Perennial - CORRECT ANSWER -A plant that lives for more than two growing seasons.
, Pesticide - CORRECT ANSWER -Any substance used to control or repel a pest, or to
reduce the unwanted or harmful effects of a pest.
Phloem - CORRECT ANSWER -A specialized plant tissue, that conducts food.
Phytotoxicity - CORRECT ANSWER -Injury or damage to a sensitive plant caused by a
chemical exposure.
Poling - CORRECT ANSWER -Brushing the surface of a turf stand with long, limber
bamboo poles. This practice helps remove water from leaves. Poling bermudagrass golf greens in
early morning helps to get rid of dew.
Predator - CORRECT ANSWER -An animal which hunts and kills other animals for food.
Relative Humidity (RH) - CORRECT ANSWER -A temperature-specific measure of the
amount of moisture held in the air. RH is the ratio of the amount of water vapor in air at a
specific temperature to the amount of Water vapor required for saturation at that temperature.
Resistance - CORRECT ANSWER -The ability of a plant to withstand infection or attack
by a pest. There are levels of resistance. For example, some plant strains may be susceptible,
weakly resistant, or strongly resistant to a specific type of pest. Total resistance is "immunity."
Saprophyte - CORRECT ANSWER -An organism that obtains its nutrition from dead or
decaying organic matter.
Aqueous Spray - CORRECT ANSWER -An application in which the pesticide product is
diluted with Water and applied as a liquid spray.
