What are some factors that you should think about before spraying

• A. Wind, temperature, droplet size
• B. Color of spray
• C. Soil texture
• D. Time of day

Answer: (A)

Before spraying, focus on conditions that determine where the spray will land and how well it stays attached to the target. The key factors are wind, temperature, and droplet size. Wind affects drift—even light air movement can push droplets off-target, so spraying in calm conditions and with awareness of wind direction reduces off-target deposition. Temperature influences evaporation and chemical behavior; high temperatures can quicken evaporation and increase drift, while some formulations may degrade or volatilize faster in heat. Droplet size matters for deposition versus drift: finer droplets provide better coverage but ride farther on air and drift more easily, whereas larger droplets are less prone to drift and deposit more reliably but may require adjustments in spray volume and pressure for adequate coverage. The other options don’t directly impact how spray behaves in the air—color of the spray is cosmetic, soil texture isn’t a primary factor for foliar spraying, and time of day is a secondary consideration that doesn’t override the main physics of drift and deposition.
