Wisconsin Pesticide Applicator Exam
Review: Turf & Landscape Questions and
Correct Answers/ Latest Update / Already
Graded
Ch.1 List the general kinds of damage insect pests can cause
Ans: -Chew on seeds, roots, leaves, stems, & fruits
-Tunnel in roots, stems, & leaves
-Suck plant juices
-Promote gall formation and other malformations
-Inject toxins into plants -Transmit diseases to plants
-Create a nuisance for people
Ch.1 Describe the structural features of insects
Ans: Insects have: body form has 3 regions: head, thorax,
abdomen; 3 pairs of legs attached to thorax; 0, 1, or 2 pairs of
wings attached to thorax; 1 pair of antennae
Ch.1 Explain how to distinguish insects from other arthropods
Ans: Arthropods have: exoskeleton; body form has 2 regions:
head & abdomen; usually 4 pairs of legs attached to head; no
wings; no antennae

Ch.1 Contrast the difference between simple and complete
metamorphosis
Ans: -Simple: "Incomplete Metamorphosis"; 3 stages: egg,
nymph, & adult
-Complete: 4 distinct stages: egg, larva, pupa, & adult
Ch.1 Explain how temperature and humidity affect insect development
Ans: *Temperature & humidity preferences vary for each
insect.
*Combined effect of both on reproduction & development is
more dramatically different than the effect of either alone.
-Temperature: development is faster with heat & slower with
cold temps; insects die at the high levels of developmental
threshold temps and become inactive at low levels
-Humidity: effects insect diseases; effects moisture levels
required for survival
Ch.1 List the advantages and disadvantages of using insecticides
Ans: Advantages:
-Effective against economically damaging pests
-Can combine 1 or 2 insecticides to combat several pests

, Page |3
-They act quickly to control pests before reaching damaging
levels
-For new pests, there are many compounds that have been
proven effective
-Effective insecticides, suitable formulations, & application
equipment are normally available
Disadvantages:
-Often eliminate beneficial insects, allowing target organisms
to rebound quickly
-Repeated exposure can lead to resistance in a pest population
-Yearly dependence on applications is an added cost
-Always a potential for drift, residues, and damage
Ch.2 Explain what determines whether a given plant is a weed
Ans: Weeds are unwanted plants
Ch.2 List the two main goals of weed management
Ans: 1. Minimize weed competition
2. Limit the weed's reproduction so that you can still manage
the weed population in future years

Ch.2 Describe ways that weeds can pose problems in turf and
landscapes (7)
Ans: -Interfere with management practices
-Produce chemical inhibitors that directly retard the growth of
desirable plants (allelopathy)
-Create a poor impression on customers
-Interferes with pesticide applications
-Support insect pests and plant diseases or provide cover for
rodents
-Are poisonous, allergenic, or irritating to people or pets
-Dry out or die and become fire hazards
Ch.2 Distinguish grasses from broadleaf plants and woody from
herbaceous plants
Ans: -Grasses (Monocots): most common weeds; have a single
seed leaf (cotyledon) when they germinate; narrow leaves with
parallel viens
-Broadleaves (Dicots): have 2 seed leaves when they germinate;
veins form a net-like or branching pattern; can be broken down
into Woody and Herbaceous plants
--> Woody: have thickened outer layer on stems (bark)
--> Herbaceous: lacks bark
