How to Use This Calculator

How the result changes with Label buffer distance (ft)

Label buffer distance (ft): Minimum buffer zone from the pesticide label.
Wind speed (mph): Current or forecasted wind speed. Most labels prohibit spraying above 10-15 mph.
Droplet size (1-6): 1=Very Fine, 2=Fine, 3=Medium, 4=Coarse, 5=Very Coarse, 6=Extremely Coarse.
Boom height (in): Height of spray boom above target canopy. Lower = less drift.
Sensitive area type (1-4): 1=Cropland, 2=Water body, 3=Residential, 4=Endangered species habitat.
Temperature (F): Ambient temperature. High heat increases droplet evaporation and drift.

Required buffer (ft): Recommended buffer zone distance in feet.
Required buffer (m): Buffer zone in meters.
Drift risk (1-4): 1=Low, 2=Moderate, 3=High, 4=Extreme drift risk.
Conditions-adjusted (ft): Buffer adjusted for wind, droplets, boom height, and area sensitivity.
Buffer area (acres): Approximate acreage lost to buffer (one side of a 40-acre field).
Wind adjustment factor: Multiplier from wind speed relative to 5 mph baseline.

Identify Input Parameters
4 parameters
Label buffer distance (ft) = 100, Wind speed (mph) = 8, Droplet size (1-6) = 3, Boom height (in) = 20 = 6 input(s) provided
Calculate Required buffer
Required buffer = max(labelBufferFt, calculatedBufferFt)
160 = 160
Calculate Drift risk
3 = 3
Calculate Required buffer
Required buffer = requiredBufferFt * 0.3048
49 = 49
Calculate Conditions-adjusted
Conditions-adjusted = labelBufferFt * windFactor * dropletFactor * boomFactor * sensitivityFactor *...
160 = 160
