A pesticide label lists the active ingredient as 'bifenthrin 25%.' What does this percentage represent?
Answer: The concentration of the active ingredient by weight in the formulation
The percentage following the active ingredient name represents its concentration by weight within the total formulated product.
Which of the following label statements would permit application of a pesticide to a home vegetable garden?
Answer: 'For residential outdoor use on vegetables'
Only a label that specifically lists residential outdoor use on vegetables would authorize that application; other statements restrict use to different settings.
What is the role of 'inert ingredients' listed on a pesticide label?
Answer: They serve as carriers, stabilizers, or solvents but do not directly control pests
Inert ingredients are non-pesticidal components (solvents, emulsifiers, stabilizers) that aid formulation and delivery of the active ingredient.
An applicator wants to tank-mix two pesticides. Product A's label states 'Do not mix with alkaline materials.' Product B has a pH of 9.5. What should the applicator do?
Answer: Do not mix Product A and Product B together
Product A's label prohibits mixing with alkaline materials, and pH 9.5 is alkaline; following label directions means the applicator must not create this tank mix.
A label includes the statement 'Groundwater Advisory: This chemical has properties associated with chemicals found in groundwater.' What does this alert the applicator to?
Answer: The product may leach into groundwater under certain soil and climate conditions
Groundwater advisories warn that the pesticide could potentially reach and contaminate groundwater, requiring careful application near wells or permeable soils.
Which label requirement must an applicator follow if state regulations are stricter than the label directions?
Answer: Follow the more restrictive state requirement, since states may impose stricter rules
States may impose requirements more stringent than the federal label, and applicators must comply with whichever standard is stricter.
What information does the 'Storage and Disposal' section of a pesticide label provide?
Answer: How to safely store the product and legally dispose of empty containers and unused pesticide
The Storage and Disposal section provides legally required instructions for safely storing the product and disposing of containers and excess pesticide in compliance with regulations.
