WA Aquatic Pest Control Test Quizzes & 100%
Correct Answers
EPA (Environmental Protection Agency)
Conducts regulation of pesticides at the federal level under the FIFRA
FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act)
requires pesticide registration, modified by the Food Quality Protection Act
WSDA and Ecology
state leg regarding use of water falls under _&_
Restricted use
all pesticides used for applications onto or into the water are designated as
general use pesticides are exempt from the restricted use designation if they are solely for
one of the 9:
Swimming pools, impounded ornamental pools or fountains, aquariums, closed pumping and

or disinfectants
Restricted use pesticide
under WA state surface water quality standards, w few exceptions, it is illegal to place any

contact WDFW when
, contact if using Gambusia for mosquito control, grass carp for weed control, or when wildlife or
inland fish might be in jeopardy from an aquatic pest management approach
contact DNR
inform if endangered species or their habitats fall within proposed application site
contact local or city planning agencies:
may request special permits, some cities have additional requirements for aquatic pesticides
ways misapplication to or near water can cause adverse effects to nontarget organisms:
acute toxicity, modifying habitats, altering O levels, or food quality and quantity
copper sulfate
used for algae control, effects trout more negatively than other fish. copper sulfate decreases in
pesticide activity with increased water hardness
response of species to pesticide
depends on sex, size, or age of exposed individual
insecticides/piscides and plants
generally nontoxic to plants unless adjuvant is added
floride treated water
injuries trees or shrubs with roots exposed to the water
insecticides/herbicides and fish
acute toxicity usually small using recommended dosage
