Row-Crop Pest Control and IPM Program

Open the field record in FieldView, Operations Center, or Agworld. Confirm V-stage or R-stage, prior pest pressure, last application date, and any residual herbicide on plant-back. Yesterday's notes from the scout drive today's threshold call.

Use a Z, W, or X pattern with at least 5 stops per 80 acres. Pull whole plants where appropriate; for soybean aphid count leaves, for corn rootworm dig roots, for white mold split stems. Avoid the field edge as your only sample — edge effects bias the count.

Misidentification drives the wrong product choice. Western bean cutworm vs. corn earworm, soybean aphid vs. potato leafhopper, Palmer amaranth vs. waterhemp — each changes the MOA decision. Send photos to your Certified Crop Adviser or the state extension entomologist when in doubt.

Use the published threshold for the pest and stage — soybean aphid at 250 per plant with rising population through R5, corn rootworm beetle at 0.75 per plant during silking, waterhemp at 4-inch height for post-emerge. Treating below threshold burns IPM credibility and accelerates resistance.

Check the FRAC, IRAC, or HRAC group on the label against the last two applications on this field. Repeating Group 14 PPO inhibitors or Group 9 glyphosate without rotation is how waterhemp populations went resistant. For organic-adjacent fields verify the product is OMRI-listed if relevant.

Confirm the applicator's private or commercial license is current with the state department of agriculture. Restricted-Use Pesticides require certified-applicator supervision. Dicamba products carry additional state-specific training requirements each year.

Flag organic neighbors, registered apiaries (DriftWatch / BeeCheck), surface water, wells, schools, and ESA-listed habitat (Bulletins Live! Two). Mark label-required buffer distances in the sprayer monitor. Drift onto a certified-organic field is a three-year decertification event for the neighbor.

Provide 24-48 hour notice where required by state law or label. For bee-toxic products applied during bloom, coordinate with the beekeeper to move or cover hives, and shift application to dusk or dawn when foragers are off.

Verify nozzle output at target boom pressure and ground speed; replace any nozzle more than 10% off the manifold average. For low-drift applications use AIXR, TTI, or ULD nozzles per label. Record the catch-test results.

Confirm boom height, downforce, and rate controller against the prescription map.

Mix products in label order (W-A-L-E: Wettable powders, Agitate, Liquids/flowables, Emulsifiable concentrates) at field rate in a quart jar. Watch for separation, curdling, or oil-out for 15 minutes. Catching incompatibility on the bench is cheaper than catching it in a 1,200-gallon tank.

Chemical-resistant gloves, coveralls, eye protection, and respirator per label. Decontamination water, eyewash, soap, and clean towels on the sprayer. Spill kit with absorbent and shovel for loading-station spills.

Lock GPS to the field boundary and load the Rx file. Hold target speed and pressure; watch for skips and overlaps on the as-applied map. If wind shifts toward a sensitive area, pause and re-evaluate before resuming.

Worker Protection Standard (40 CFR 170) requires central posting plus oral notification for some products. Sign stays up through the full restricted-entry interval — 4, 12, 24, 48 hours, or longer per label.

Capture field, date, time, product, EPA registration number, rate, total applied, applicator name and license number, target pest, REI, PHI, and weather conditions. Federal retention is 2 years; many states require 3-5. File in PestPilot, Agworld, or the binder before the state-required window (commonly 14-30 days).

Triple-rinse or pressure-rinse jugs per label and route to the Ag Container Recycling Council collection point. Capture rinsate at the wash pad and apply back to a labeled crop within label rates — never down a storm drain or onto bare ground near a wellhead.

Pull samples from the surviving population for the state extension diagnostic lab. Document the MOA group, rate, adjuvant, and conditions. Confirmed resistance changes next year's rotation plan and may trigger a Take Action stewardship report.

Roll lessons into the field's IPM plan — rotation, MOA sequencing, cover crop choice, refuge compliance for Bt corn, scouting cadence. The plan feeds next year's seed-and-chemical order with the agronomist.
