Integrated Pest Management and Pesticide Disposal
IPM fundamentals
Integrated Pest Management (IPM) is a decision framework: identify the pest, monitor/scout, establish an action threshold, choose the least-risk effective tactic, and evaluate results. Tactics are layered - cultural, mechanical/physical, biological, and chemical - with pesticides used only when justified. Exam questions reward the sequence: identify and monitor before treating; treat only when thresholds are exceeded; prefer the least-risk option that works.
Traps in IPM questions
- Choosing a pesticide as the first step rather than the last.
- Ignoring thresholds and treating on a calendar schedule.
- Confusing prevention (cultural practices) with control (direct intervention).
- Forgetting to evaluate and record outcomes.
Pesticide disposal
Improper disposal harms people and the environment. Key concepts: never pour pesticides down drains or into storm sewers; follow the label for disposal; use up or properly dispose of excess product; participate in collection programs (household hazardous waste/agricultural collection) where available; triple-rinse containers and dispose of rinseate in the spray tank, then dispose of containers per label and state rules. Questions often test container rinsing and whether rinseate may be dumped - it should go into the tank, not the ground.
Storage and spills
Store pesticides securely, away from food and water, in original labeled containers. For spills: protect people, contain the spill, and follow label/emergency guidance. Reportable spills go to DEEP.
Rule of thumb
For IPM: identify, monitor, threshold, least-risk tactic, evaluate. For disposal: use it up, rinse it right, never dump it.
