What might be a result of using pressure settings that are too high for nozzles?

Using pressure settings that are too high for nozzles can significantly increase the likelihood of drift. When sprayers operate at elevated pressure, they create smaller droplet sizes. These smaller droplets are more susceptible to being carried away by wind, leading to unintentional spraying of pesticides in non-target areas. Drift can pose risks to neighboring crops, wildlife, and even human populations, making it a crucial concern for applicators.

The other options do not accurately reflect the consequences of using excessively high pressure settings. Increased spray coverage or less pesticide required are not typically outcomes associated with high pressure, while destruction of beneficial insects, although a potential consequence of pesticide use generally, does not directly correlate with high pressure settings specifically.
