Key Terms Exam Questions with Correct Answers
100% Verified Graded A+
1. Calibrate
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.
2. Disease
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.
3. Exclusion
Answer: Using some sort of barrier to keep a pest out of an area.
4. Exposure
Answer: Coming in contact with a pesticide either by ingestion (oral), inhala- tion, or
absorption through the skin (dermal).
5. Habitat
Answer: A speci c area or environment in which an organism normally lives.
,6. Insect
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.
7. Integrated Pest Management (IPM)
Answer: VA management system that uses all ap- propriate pest control strategies to
reduce pest populations to an acceptable level. IPM uses an ecological approach to pest
management.
8. Life Cycle
Answer: An 0rganism's progression through developmental stages. As some organisms go
through their life cycle, they change in body form and habits.
9. Mite
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.
10. Mollusk
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.
,11. Monitoring
Answer: The process of assessing-"keeping tabs on"—the size and distrib- ution of a pest
population in an area.
12. Natural Controls
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.
13. Nematode
Answer: A small, unsegmented roundworm. Most nematodes are so small that they
cannot be seen with the naked eye.
14. Leaching
Answer: Movement of a substance (such as a pesticide) in solution downward through soil.
15. Nematicide
Answer: A pesticide that controls nematodes.
16. Parasite
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.
, 17. Perennial
Answer: A plant that lives for more than two growing seasons.
18. Pesticide
Answer: Any substance used to control or repel a pest, or to reduce the unwanted or
harmful effects of a pest.
19. Phloem
Answer: A specialized plant tissue, that conducts food.
20. Phytotoxicity
Answer: Injury or damage to a sensitive plant caused by a chemical exposure.
21. Poling
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.
22. Predator
Answer: An animal which hunts and kills other animals for food.
23. Relative Humidity (RH)
Answer: A temperature-speci c measure of the amount of mois-
ture held in the air. RH is the ratio of the amount of water vapor in air at a speci c
