asonic weather sensors can help. A far cry from yesterday’s rudimentary weather vanes, sensors measure air temperature, humidity, dew point, barometric pressure, wind chill, wind direction and wind speed. The units are extremely compact and can be mounted inside a sprayer cab. That means the applicator has continuous, up-to-date weather data and can apply herbicides when they are least likely to drift.

CONTROL THE FLOW. Modulated flow controls reduce drift by rapidly pulsing each spray nozzle on and off. This allows pressure and droplet size to remain constant as the sprayer moves across the field at various speeds.

REV UP THE AIR SPEED. Air-assisted sprayers emit a high-velocity, downward air stream that pushes the spray droplets directly onto the targeted weeds or treatment area. As a result, they can reduce drift if used properly.

CREATE A BUFFER. Untreated zones around fields can serve as buffers that keep drift away from off-target sites. < '/>"/>
