🧪 Pesticide Contamination Control

About this simulation

Treated crop fields sit near apiaries, and spray drift — pesticide particles carried by wind off the target field — is one of the main routes by which residues end up in honey, wax and bees. Operations manage this risk with buffer zones (unsprayed or planted strips between field and hives) and a QA testing loop that periodically samples for residue so a breach is caught early rather than discovered in finished honey.

How it works

• Amber drift particles emit continuously from the field edge, carried by the wind vector toward the apiary.
• Crossing the green buffer strip gives each particle a chance of being filtered out — wider buffers absorb more drift.
• Particles that reach the hives raise the hive residue reading, which also decays over time (breakdown / dilution).
• The lab rack samples the current residue on a fixed test interval, filling a vial and colour-coding it green / amber / red.
• If residue crosses the quarantine threshold, a red ring appears around the apiary and the status pill switches to QUARANTINE.

Controls

• Buffer zone width — width of the unsprayed strip between field and hives (10–100m).
• Wind speed — how fast drift particles travel toward the apiary.
• Drift angle off-line — how far the wind direction deviates from a direct line to the hives.
• Test interval — how often the QA lab samples and tests residue.
• ⚠ Trigger spray-drift incident — simulates an off-target application error with a concentrated burst of drift.

Did you know?

Regulatory pre-bloom or in-crop buffer zones are one of the cheapest and most effective contamination controls available — because drift concentration falls off sharply with distance, even a modest unsprayed margin can cut the dose reaching a hive by an order of magnitude.
