If the pressure is too high, what risks increase?

• A. Increased nozzle wear and drift risk
• B. Decreased chemical effectiveness only
• C. No change
• D. Improved pattern accuracy

Answer: (A)

When spray pressure is too high, the spray forms very fast, very fine droplets that are easy for wind to carry away. That increases drift and off-target contamination, which means more chemical lands where you don’t intend it and potentially exposes people, animals, or non-target plants. At the same time, the high-velocity flow can wear down nozzles and seals more quickly, shortening nozzle life and changing the spray pattern over time. All of this reduces effective coverage on the intended target and wastes product. So the main risks are more drift and accelerated nozzle wear, rather than improved effectiveness or pattern accuracy.
