WITH UPDATED QUESTIONS AND
DETAILED CORRECT ANSWERS WITH
RATIONALES (ALREADY GRADED A+)
How and when should you apply soil herbicides? - ANSWER-Soil
treatments are commonly used when a site requires residual nonselective control, such as electric transformer stations, rail
ballasts and signpost bases. They can be applied any time that
the soil is not frozen, and some soil applied herbicides need to be
transported by rain to be absorbed by the plant.
How are adjuvants used most effectively? - ANSWER-Adjuvants
may be necessary to use for better absorption by foliage that is
extremely waxy or hairy.
How are pesticides assigned to toxicity categories or given signal
words? - ANSWER-The signal words are assigned on the basis of
the highest measured toxicity, whether that is oral, dermal or
inhalation. Signal words indicate the relative toxicity of the
pesticide.
How can pesticides get into groundwater or surface water, and
what do the terms point and non-point source pollution mean? -
ANSWER-Point source pollution is: a pest. spill entering a storm
sewer, back-siphoning, repeated spilling of pests. at mixing and
loading sites, careless spilling of wash water at equip. cleanup
sites, improper handling of spills and leaks at storage sites and
improper disposal of containers, rinsate and excess pests.

Non-point source pollution: the movement of pests. into streams
or groundwater following a broadcast application to a large turf
area, right-of-way, or agricultural field.
Compare and contrast Solid and Hazardous wastes: - ANSWERSolid wastes can sometimes be solid, liquid or contained gas, in
terms of pest. disposal, solid waste is anything that is not
considered hazardous waste. Hazardous waste is the pest. itself if
determined as such by the SDS.
Compare selective and non-selective herbicides: - ANSWERSelective herbicides only harm certain plants and leave others
unharmed. Non-selective herbicides are toxic to most or all plants.
Define and explain "pesticide". - ANSWER-A pesticide is any
substance used to directly control pest populations or to prevent
or reduce pest damage. Pesticides can range from anything such
as an insecticide to a herbicide to a fungicide.
Define overspray and drift. - ANSWER-Overspray is the direct
application of pests. beyond the boundaries of the target area.
Drift is the movement of pests. in air currents onto property
beyond the boundaries of the target area.
Describe the function of inert ingredients: - ANSWER-They do not
possess pesticidial activity but are added to improve application
effectiveness, safety, handling, storage or other characteristics of
the final product.
Describe the life cycles and propagation of annual, biennial, and
perennial plants - ANSWER-Annual plants live for less than a
year, they produce many seeds in one growing season, and then
die. Summer annuals winter as seeds, and winter annuals winter
as a low-growing plant, both summer and winter annuals are
easiest to control when they are small. Biennial plants live for two
growing seasons, they germinate from seed in the spring or

summer and winter as a rosette of leaves. They flower in their
second year, produce seeds and then die. Both annuals and
biennials reproduce only by seed. Perennial plants live for at least
2 years and sometimes longer, they may reproduce by seed or
vegetatively through several different mechanisms.
Describe the short-term storage of empty containers and of
pesticides at an application site: - ANSWER-You must cover or
otherwise secure pesticides and containers that you temporarily
hold at a mixing and loading or application site to prevent
unauthorized access or water contamination. You must have a
designated area for properly rinsed containers.
Distinguish grasses from broadleaf plants and herbaceous from
woody plants - ANSWER-Grasses are considered monocots,
meaning they have a single seed leaf, they also have narrow
leaves with parallel veins and a fibrous root system. Broadleaf
plants have two seed leaves and are therefore called dicots, they
have broad leaves with veins that form a net patterns. Broadleaf
plants can be further classified into herbaceous and woody,
where the woody plants have a thick layer of dense tissue called
bark, which herbaceous plants lack.
How can the different characteristics of pesticides effect
movement of a pesticide from a target site? - ANSWER-Solubility,
absorption, volatility and persistence all effect the movement of a
pest. off target.
