Category Standards: Application Practice and Pest Control Judgment
Match the method to the pest and site
Category questions reward integrated pest management (IPM): identify the pest, monitor, set an action threshold, choose the least-risk effective method, and evaluate results. Know your application types-foliar, soil, seed treatment, bait, crack-and-crevice, broadcast, banded, directed-and when each is appropriate. Traps: treating a symptom without identifying the pest, or choosing a broad-spectrum product where a targeted bait or biological control would work.
Calibration and rates are exam favorites
You must be able to reason about rate per acre, concentration, and calibration. Know that nozzle type, pressure, and speed change output, and that you calibrate to deliver the labeled rate-not to make the tank "look right." Understand spray drift reduction (coarser droplets, lower boom height, correct nozzles) and the difference between contact and residual products.
Resistance, phytotoxicity, and records
Expect questions on rotating modes of action to manage resistance, avoiding phytotoxicity through correct timing and rate, and keeping application records that satisfy both label and state requirements. Also know storage, transport, and container triple-rinsing or pressure-rinsing, plus disposal.
Worked example (rule of thumb): If a label calls for 1 quart per acre and your calibrated sprayer delivers 20 gallons per acre, each 20-gallon tank treats one acre, so add 1 quart per tank. If your sprayer delivers 25 gallons per acre, you still add 1 quart per acre-but you'll cover less ground per tank, so recalculate the acres per tank before mixing.
