Category 3B Turf Pest Control Key
Terms Questions with Correct
Answers
Calibrate - ANSWERSTo 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 - ANSWERSAn 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 - ANSWERSUsing some sort of barrier to keep a pest out of an area.
Exposure - ANSWERSComing in contact with a pesticide either by ingestion (oral),
inhalation, or absorption through the skin (dermal).
Habitat - ANSWERSA specific area or environment in which an organism normally lives.
Insect - ANSWERSAn 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) - ANSWERSVA 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 - ANSWERSAn 0rganism's progression through developmental stages. As
some organisms go through their life cycle, they change in body form and habits.
Mite - ANSWERSA 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 - ANSWERSA 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 - ANSWERSThe process of assessing-"keeping tabs on"—the size and
distribution of a pest population in an area.
, Natural Controls - ANSWERSNatural 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 - ANSWERSA small, unsegmented roundworm. Most nematodes are so
small that they cannot be seen with the naked eye.
Leaching - ANSWERSMovement of a substance (such as a pesticide) in solution
downward through soil.
Nematicide - ANSWERSA pesticide that controls nematodes.
Parasite - ANSWERSAn 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 - ANSWERSA plant that lives for more than two growing seasons.
Pesticide - ANSWERSAny substance used to control or repel a pest, or to reduce the
unwanted or harmful effects of a pest.
Phloem - ANSWERSA specialized plant tissue, that conducts food.
Phytotoxicity - ANSWERSInjury or damage to a sensitive plant caused by a chemical
exposure.
Poling - ANSWERSBrushing 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 - ANSWERSAn animal which hunts and kills other animals for food.
Relative Humidity (RH) - ANSWERSA 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 - ANSWERSThe 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 - ANSWERSAn organism that obtains its nutrition from dead or decaying
organic matter.
