WISCONSIN PESTICIDE APPLICATORTURF
AND LANDSCAPE EXAM WITH UPDATED
QUESTIONS AND DETAILED CORRECT
ANSWERS WITH RATIONALES (ALREADY
GRADED A+)
Ch.1 Contrast the difference between simple and complete
metamorphosis - ANSWER--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 - ANSWER-*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
- ANSWER-Advantages:
-Effective against economically damaging pests
-Can combine 1 or 2 insecticides to combat several pests
-They act quickly to control pests before reaching damaging
levels
-For new pests, there are many compounds that have been
proven effective
2 | P a g e
-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.1 List the general kinds of damage insect pests can cause -
ANSWER--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 - ANSWERInsects 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 -
ANSWER-Arthropods have: exoskeleton; body form has 2
regions: head & abdomen; usually 4 pairs of legs attached to
head; no wings; no antennae
Ch.2 Explain what determines whether a given plant is a weed -
ANSWER-Weeds are unwanted plants
Ch.2 List the two main goals of weed management - ANSWER-1.
Minimize weed competition
2. Limit the weed's reproduction so that you can still manage the
weed population in future years
3 | P a g e
Ch.2 Describe ways that weeds can pose problems in turf and
landscapes (7) - ANSWER--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 - ANSWER--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
Ch. 2 Describe the life cycles and propagation of annual, biennial,
and perennial plants - ANSWER--Annuals: live less than 12
months; most seeds germinate the following year, some are
dormant taking several years; prolific seed producers.
--> Summer Annuals: germinate from seed in spring,
flower/produce seeds in summer, die in late summer/early fall.
--> Winter Annuals: germinate from seed in fall, overwinter as
low-growing plants, flower/produce seeds in spring, then die.
-Biennials: live for 2 growing seasons; germinate from seeds in
spring or summer and produce a rosette of leaves, overwinter in
rosette stage, flower the following year, produce seed, and die.
-Perennials: live for at least 2 years, sometimes longer; may
reproduce by seed or spread vegetatively (stolons, rhizomes,
spreading roots, tubers, bulbs)
