Target coverage and potential for spray drift are determined by which factor?

Target coverage and potential for spray drift are determined by which factor?

• A. Pressure
• B. Droplet size
• C. Boom height
• D. Weather conditions

Answer: (B)

Droplet size directly controls how much product lands on the target and how far droplets can travel off-target. Smaller droplets stay aloft longer and are more easily carried by wind, improving coverage in difficult-to-reach spots but increasing drift risk. Larger droplets deposit more quickly near the application point, reducing drift but potentially leaving gaps in coverage if they’re too large for the target surface. So, the size of the droplets determines both how well the target is coated and how much drift you might see. Other factors like pressure, nozzle type, boom height, and weather influence how those droplets behave, but the size of the droplets is the primary determinant of both coverage and drift potential.
