Which practice is required when disposing of empty pesticide containers?
Answer: Triple rinsing them and following label disposal instructions
EPA regulations require that empty pesticide containers be triple-rinsed (or pressure-rinsed) and disposed of according to label instructions, which may allow landfill disposal after rinsing.
What does a pesticide's 'mode of action' describe?
Answer: The biochemical mechanism by which the pesticide kills or disrupts the target pest
Mode of action refers to the specific biochemical or physiological process by which a pesticide affects the target organism, such as inhibiting a specific enzyme or receptor.
Synergism in pesticide mixtures refers to:
Answer: A combined toxicity greater than the sum of the individual components
Synergism occurs when combining two pesticides produces a toxic effect greater than the additive effect of each pesticide applied separately.
An insecticide is described as having systemic activity. This means it:
Answer: Is absorbed by the plant and translocated to tissues where pests feed
Systemic insecticides are absorbed into plant tissue and transported throughout the plant, so feeding insects are exposed to the chemical regardless of where they feed.
Which symptom is most characteristic of organophosphate or carbamate insecticide poisoning in humans?
Answer: Excessive salivation, pinpoint pupils, and muscle tremors
Organophosphate and carbamate poisoning causes cholinergic crisis: excessive secretions, miosis (pinpoint pupils), muscle fasciculations, and tremors due to acetylcholinesterase inhibition.
When a pesticide label states 'Do not apply within 50 feet of water,' this buffer zone requirement is intended primarily to:
Answer: Protect aquatic organisms from pesticide runoff and drift
Buffer zones near water bodies protect aquatic ecosystems, including fish and invertebrates, from pesticide runoff, spray drift, and leaching.
Which document must accompany a restricted-use pesticide (RUP) applicator to provide product safety and emergency response information?
Answer: The Safety Data Sheet (SDS) for the product
The Safety Data Sheet (SDS), formerly called MSDS, must be available during transport and use of pesticides and contains toxicological, first aid, and emergency response information.
