Pest Identification and Integrated Pest Management
Pest Identification and Integrated Pest Management
This domain tests whether you can identify the pest and its life stage, then select tactics that are least risky and most likely to work. Massachusetts exams emphasize practical scouting, thresholds, and resistance management, not just product names.
Core rules
- Identify before treating: insect, mite, weed, disease, vertebrate. A damaged leaf can be disease, herbicide injury, or insect feeding.
- Scout and monitor with consistent units (per leaf, per square foot, per trap).
- Use action thresholds and record counts; a threshold is not a label rate.
- Build an IPM program: cultural, mechanical/physical, biological, then chemical when justified.
- Rotate modes of action (IRAC/HRAC groups) to slow resistance.
- Protect beneficials and pollinators; avoid broad-spectrum sprays during bloom.
Worked example
A lawn has thin, droughty patches. You pull back turf and find 12 white grubs per square foot in late summer. Reasoning: the symptom alone is ambiguous; the grub count is the diagnostic. A threshold for cool-season turf is often 5–10 grubs/ft², so 12 exceeds it. You confirm the species and life stage, check soil moisture, and choose a label-approved product timed for the susceptible stage, plus cultural fixes such as proper irrigation and thatch management. You record the count and the treatment.
Traps
- Treating on a calendar schedule without scouting.
- Calling every yellow leaf a disease.
- Counting grubs after they have pupated and expecting control.
- Using a broad-spectrum product when a targeted bait or cultural fix would work.
- Ignoring the label's site and pest restrictions.
