Which best management practice will help prevent contamination
of surface water and groundwater by pesticides?
a) using pesticides that are highly water-soluble
b) Following IPM principles
c) selecting persistant pesticides - ANSWER-b) Following IPM
principles
Which 2 factors are most important in avoiding vapor drift?
a) Droplet size and wind speed
b) air stability and temperature
c) temperature and pesticide volatility - ANSWER-c) temperature
and pesticide volatility
Which statement about sensitive areas is true?
,2|Page
a) do not spray a larger target site if it contains a sensitive area
b) Pesticide labels may list special precautions around sensitive
areas
c) endangered species' habitats are not considered sensitive
areas - ANSWER-b) pesticide labels may list special precautions
around sensitive areas
Which statement about protecting bees from pesticide injury is
true?
a) Use foliar applications when possible
b) Spray crops when they are in bloom
c) apply insecticides in the evening or at night - ANSWER-c)
apply insecticides in the evening or at night
List and describe the physical and chemical characteristics of
pesticides that determine how they will interact with the
environment (4) - ANSWER--solubility- ability of a pesticide to
,3|Page
dissolve in a solvent-usually water, high solubility more likely to
move with water in runoff or thru soil
-adsorption- the process by which a pesticides bind to soil
particles- oil-soluble pesticides more attracted to clay and org
matter than water-soluble- pesticides that adsorb less likely to
move from spray site
-persistence- the ability of a pesticide to remain present and
active in its original form for an extended period of time before its
breakdown, longer half-life longer persistence,
-volatility- tendency of a pesticide to turn into a gas or vapor,
volatilization positively correlated with temperature, negatively
correlated with RH (evap increases in drier conditions)
List and describe the processes that breakdown pesticides (3) -
ANSWER--chemical degradation- breakdown chemicals that does
not involve living organisms- usually thru chemical reactions with
water
, 4|Page
-microbial action- breakdown of chemicals by microorganisms,
fungi & bacteria
-photodegradation- breakdown of chemicals in reaction to sunlight
**water and temperature also affect breakdown- warm, wet
conditions speed up breakdown, cool, dry conditions slow down
breakdown
Define drift - ANSWER-Pesticide movement away from
application site by wind or air currents
What are the 2 ways pesticides move in water? when do they
occur? - ANSWER--runoff, can travel great distances
-leaching, can contaminate groundwater
occur when:
-too much pesticide applied or spilled
-too much rainwater or irrigation
