Answers----c) pesticides that dissolve and leach through soil after it
rains
Under which conditions are pesticides more likely to leach through soil?
a) heavy clay soil, high in organic matter
b) sandy soil, high in organic matter
c) sandy soil, low in organic matter ----Answers----c) sandy soil, low
in organic matter

first-attempt success and A+ Grade
, Created by AnswersCOM@stuvia 2026/01/09 Page 4 of 92

b) Pesticide labels may list special precautions around sensitive areas
c) endangered species' habitats are not considered sensitive areas ----

c) apply insecticides in the evening or at night ----Answers----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) ----Answers-----solubility- ability of a pesticide to 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)
