"Pre-emergent Pesticides - CORRECT ANSWER Needs to be applied before seedings germinate"
"Post-emergent Pesticides - CORRECT ANSWER Needs to be applied after seedlings come up"
"Short-term Pesticides - CORRECT ANSWER These have no residual activity and are only active on pests
that are hit with it"
"Residual Pesticides - CORRECT ANSWER These remain active and control pests for days, weeks, months,
and in some cases even years. They stay active in the soil."
"Foliar Pesticides - CORRECT ANSWER These are applied to plant leaves, stems, and branches. They can
be contact or systemic."
"Soil Applied Pesticides - CORRECT ANSWER These are applied to the soil. Some are taken up by roots
and translocated inside the plant. Others kill week seedlings by contact with young shoots or leaves as
they break through the soil."
"Protectant Pesticides - CORRECT ANSWER These are fungicides that prevent fungal infections in plants.
They need to be used before the fungi reach the infection stage."
"Eradicant Pesticides - CORRECT ANSWER These are fungicides that destroy the fungi that have already
invaded plants and begun to damage plant tissues."
"What are the two main pesticide classifications? - CORRECT ANSWER General use and restricted use"
"4 types of pesticide registration - CORRECT ANSWER Section 3 - full federal label
Section 18 - emergency exemptions
Section 24c - special local needs label
Section 25b - minimum risk pesticides"
"Pesticide Registration: Section 3 - Full Federal Label - CORRECT ANSWER Outlines pesticide registration
requirements that manufacturers must follow.
Most pesticides are registered this way"
"Pesticide Registration: Section 18 - Emergency Exemptions - CORRECT ANSWER Allows state and
federal agencies to permit an additional use during a short term pest management crisis in a specific
locality.
Manufacturer is not allowed to advertise or promote the use of the product under this, even though the
use is legal.
This is used when there is a crisis and there are no federally registered pesticides available to control the
problem."

same pesticide"
"Federal Food, Drug and Cosmetic Act (FFDCA) - CORRECT ANSWER Passed before FIFRA to set
maximum residue levels for unavoidable poisonous substances in food marketed in the US.
Administered by the FDA but the EPA has a role
EPAs role: sets tolerances for pesticide residues on food commodities in the US
FDAs role: Monitors food crops for pesticide residues and enforces the levels set by the EPA."
"Worker Protection Standard (WPS) - CORRECT ANSWER Federal regulation passed in 1974 to provide
protection to workers who perform hand labor tasks in fields after a pesticide application.
Recently updated in 2015 to increase protection to workers.

This labeling can be found in the "Directions for Use" in the "Agricultural Use Requirements" section of
the label"
