Increasing spray pressure is not recommended to minimize pesticide drift because higher pressure can lead to the production of smaller spray droplets that are more susceptible to wind movement. When spray droplets are too fine, they can be carried away from the intended target area by air currents, increasing the risk of drift. Instead, using a correctly chosen nozzle, monitoring weather conditions, and keeping the spray nozzle close to the target are effective strategies that help create larger droplets, reduce spray volatility, and ensure better coverage of the target area, ultimately reducing the potential for drift.
