Articles helping with field sprayer nozzle selection
Sprayer manufacturers have all but offloaded the entire responsibility for drift management to the sprayer nozzle. It’s asking too much. Sprayers have changed a lot over the past 25 years. They have become larger, with more tank capacity, boom width, and, if self-propelled, horsepower. They are more comfortable and ergonomic, with more sophisticated swath control […]
There’s a call that I’ve been getting for 20 years now. It came again this week. Someone has a twincap with two small air-induced tips, and they’re applying herbicides and fungicides with low water volumes, often 5 gpa, sometimes less. They call because they want to know how much wind they can spray in. Is […]
Us this handy visual guide to identify a mystery nozzle you may find on a field sprayer. We’ve included the most common low-drift nozzles found on North American, European, and Australian sprayers. The list does not contain any conventional flat fan nozzles. It’s in alphabetical order by manufacturer. First, a reminder of the ISO colour […]
Picking the correct nozzle for a spray job can be a daunting task. There is a lot of product selection, and a lot of different features. We try to break the process down into four steps. 1. Identify Your Needs Before making any assumptions about the right nozzle for you, review your needs and objectives. […]
Pressure is integral to nozzle performance. Reducing hydraulic pressure reduces nozzle flow rate, increases median droplet size, and typically reduces spray fan angle. Increasing pressure increases nozzle flow rate, reduces median droplet size and typically increases spray fan angle. You can watch this Exploding Sprayer Myths video to learn how pressure, boom height and nozzle spacing […]
