Which spray droplet characteristic reduces drift during pesticide application?

Which spray droplet characteristic reduces drift during pesticide application?

• A. Larger droplets
• B. Smaller droplets
• C. Irregular droplets
• D. Fuzzy droplets

Answer: (A)

Droplet size governs how much a spray stays in the air versus how quickly it settles to the target. Larger droplets have more mass and momentum, so gravity pulls them down faster and they are less easily blown off-target by wind. This makes drift less likely compared to smaller droplets, which are light enough to be carried by air currents and travel farther before landing. The idea of “irregular” or “fuzzy” droplets isn’t a standard factor used to reduce drift, so they don’t provide a reliable way to prevent off-target movement. Keep in mind that while large droplets reduce drift, they can affect coverage, so growers balance droplet size with the need for adequate pest control.
