Drift of agricultural spray nozzles

In the field of plant protection, the agent-laden droplets that do not land on the target surface but are instead carried off by the wind or thermal currents are referred to as drift.

Such errant additions to surrounding areas can damage adjacent crops, contaminate nearby waters, endanger man and animals, emburden other crops and adulterate the dosage applied to the target crop.

Drift is caused by a number of equipment-specific and meteorological factors, e.g.:

• Droplet size
• Sprayer speed
• Spray height
• Wind velocity
• Relative temperature
• Ambient humidity
