Sprayer Drift

May 29, 2020


With the first pass of spraying getting wrapped up, the second pass won’t be too far behind. With crops emerged, sensitive plants are going to be closer than you think. There are a few ways to combat off-target drift. The first way is to be mindful of wind direction and wind speed. The label will also instruct you on how much wind you can spray in, and if a buffer (space between you and the neighboring field) is needed. It will also let you know if you can spray at all with sensitive crops around.
 
The second way to combat drift is with air induction nozzles, or AI nozzles. The nozzle is designed to induct air into the droplet to make it bigger and reduce fine droplets produced by the sprayer. Less fine and bigger droplets mean less off-target drift. Along with nozzles, lowering your speed and using the correct nozzle size will reduce the pressure coming out of the nozzles. Again, higher pressure means smaller droplets, lower pressure means bigger droplets.
 
The final way to combat drift is using adjuvants such as a drift retardant. Hi-Line Co-op carries a number of these products used for reducing drift. Based on what chemicals/fertilizers you are spraying and what nozzles you are using, your local Hi-Line Salesmen can help you find the best product for your needs to help reduce drift while spraying.
