Why are buffer zones important around treated areas?

• A. To increase spray coverage
• B. To allow spraying without buffer zones
• C. To shorten the application time
• D. To reduce drift and protect sensitive areas

Answer: (D)

Buffer zones are areas around the treated site where spraying is not allowed to create distance between the pesticide and nearby people, wildlife, and sensitive environments. This helps prevent spray drift, the tiny droplets that can travel with the wind and land where you don’t intend them to go. Drift is influenced by factors like droplet size, nozzle type, spray pressure, boom height, wind speed, and temperature/humidity. By maintaining a buffer, you reduce the chance that these droplets reach adjacent homes, gardens, streams, wells, beehives, or other sensitive areas, thereby protecting people and the environment. That’s why reducing drift and safeguarding sensitive areas is the primary purpose of buffer zones.
