Tips for Reducing Spray Drift

Posted on February 18, 2014 in Featured, Maintenance, Sprayer, Spring.

One of the biggest concerns of producers today is reducing spray drift. Because weather conditions limit the available spraying time and the consequences of spray drift can be severe, it is essential to spray crops in the most efficient way possible. Fortunately there are a few strategies for properly managing spray drift.


Monitor Your Droplet Size

The size of a droplet affects how the spray moves through the air. Larger droplets will fall faster, decreasing the likelihood of drift. As you approach neighboring crops, slow down and reduce nozzle pressure to allow your spray will hit its target without affecting nearby crops.

Nozzle Selection and Replacement

Each nozzle is created for a different application. Talk to your New Holland dealer to find the nozzle that’s right for your job. All nozzles produce a variation of droplet sizes and flow rates, but the deviation increases as the nozzle starts to wear. Change your nozzles as they age to ensure top-notch performance. New Holland sprayer performance kits come with a calibrator, which can be used to analyze spray nozzle output, determine nozzle wear and verify that your nozzle is within specifications.

Weather Conditions

Before you start, check that the weather conditions are suitable for spraying. Wind speed and direction has the greatest impact on spray drift. Pay close attention to weather conditions throughout the day and adjust your application methods accordingly.

Nighttime Spraying

Recent studies show there are many benefits of spraying at night. Chemicals evaporate slower in the dark, allowing for higher absorption rates. Plants are also less stressed in the dark, so the fluid will move more easily through the plant. At night, there is less wind and spray drift, so not a single drop will be wasted.
