Final answer:
Using the largest droplets practical to provide necessary coverage is the technique that helps minimize off-target drift when spraying pesticides.
Step-by-step explanation:
To minimize off-target drift when spraying pesticides, the technique that should be used is using the largest droplets practical to provide necessary coverage. Using larger droplets helps reduce the chances of the pesticide being carried away by wind and reaching unintended areas. This is because larger droplets are less affected by air currents and have a higher chance of hitting the intended target. Spraying during a temperature inversion and increasing the height of the nozzles above the target can actually increase off-target drift and should be avoided.
