How does the height of pesticide release impact drift potential?

• A. The higher you release, the greater the drift risk
• B. The higher you release, the lower the drift risk
• C. Height has no effect on drift potential
• D. Drift only depends on ground conditions

Answer: (A)

When spray is released higher, the droplets spend more time in moving air and are exposed to stronger and more variable wind currents, which lets them travel farther before gravity pulls them down. Fine droplets are especially carried by those airflows, so the drift potential increases as height goes up. So, increasing the release height raises the chance that droplets will drift onto non-target areas. To reduce drift, keep the release height as low as feasible and use appropriate nozzle types and droplet sizes.
