Make sure that your operating pressure is within the range of your sprayer nozzle. ![]() Most nozzles have an operating range of about 20-60 Psi, some have a larger range, 15-90. 30 or 40-inch nozzle spacings, usually for fertilizer or turf spray, will require flood nozzles or extra wide fans 120 degrees or more. They allow for the needed overlap on 15 and 20-inch spacing, to provide effective coverage. 110-degree flat fan nozzles are most common now on ag sprayer booms. Nozzle spacing on your boom is also a factor in determining your spray nozzle. Lawn and turf spraying may be done with flood tips as well when drift is a concern. Fertilizers may be applied via solid or multiple stream nozzles or flood nozzles. These are flat fan spray nozzles overlapping on your boom to provide even coverage. Most herbicides for row crops will be applied via broadcast spraying. The mechanics of how you will spray go along with what you are spraying. One material type may last much longer than others with specific products. These materials will work with most chemicals, pesticides, etc., but it is smart to check. Most sprayer tips for ag, turf, & lawn use are made from materials like ceramic, acetal, polypropylene, and stainless steel. Some materials may not be compatible with your product. The material that the spray tip is made out of is another reason why the product you spray is important. Generally, for herbicides you will utilize a flat fan sprayer nozzle, fertilizer is generally applied by stream nozzles or flood tips. There are different nozzles for herbicides, fertilizer, fungicides, etc. Other products may provide little to know advice. Many products will provide more general suggestions like: “use a flat fan tip that produces a fine droplet size, or use a cone nozzle that produces a coarse droplet”. For specific chemicals and pesticides, the product label may even tell you a specific type of tip or manufacturers part number to use. The product that you are going to spray is important because the label may provide specific instructions on how to spray and what nozzle to use. You will likely find that for a given application you may be able to use 2 or 3 different nozzles that will work. Asking questions about your specific scenario will help you determine the right nozzle. You can read the post: “ What Do The Numbers On A Sprayer Nozzle Mean” want to know more about the differences in the nozzle types available. Your specific spraying scenario will determine what nozzle to use. How to Choose the Correct Sprayer Nozzle Type Finally, the nozzle type will determine the droplet size which affects potential drift. It is also going to affect the coverage your sprayer can provide on the weed or surface you are spraying. The spray nozzle plays a huge role in determining the amount of chemical applied to a given area. Selecting the correct sprayer nozzle is important for many reasons.
