BROOKINGS, S.D. -- A South Dakota State University publication can help crop producers choose drift-reducing sprayer nozzles this season.
South Dakota Cooperative Extension Service Fact Sheet 919, “Selecting drift-reducing nozzles,” is available at http://agbiopubs.sdstate.edu/articles/FS919.pdf. Or ask at your county Extension office.
SDSU Extension Pesticide Education Coordinator Jim Wilson compiled and wrote the publication along with North Dakota State University Agricultural Machine Specialist John Nowatzki and NDSU professor emeritus Vern Hofman. It examines the differences among conventional nozzles, air-induction nozzles, and other drift-reduction techniques.
The publication shows the range of droplet sizes and the different droplet patterns associated with each nozzle.
The authors also deal with other factors such as pressure, speed, nozzle size, boom height, nozzle wear, and plugging.
“It’s important to think in terms of using the ‘right spray for the condition.’ This may mean using a conventional tip under one situation and a drift-reducing tip under another,” Wilson said. “Nozzles are the most important part of your sprayer. It makes sense to invest in the proper nozzle to make sure the job gets done right.”
