The Effect Of Adjuvants, Pesticide Formulation, And Spray Nozzle Tips On Spray Droplet Size, Robert N. Klein, Jeffrey A. Golus, Kelli L. Nelms
West Central Research and Extension Center, North Platte
Many factors, including adjuvants, pesticide formulations, and nozzle tips, affect spray droplet size. It is important to understand these factors as spray droplet size affects both drift and efficacy of pesticides, which is a main concern with pesticide application. A laser particle analyzer was used to determine the spray droplet size and distributions of a range of formulations sprayed through several types of nozzle tips. Nozzles included were extended range flat fan sizes 11003 and 11005 (Spraying Systems XR), air induction flat fan sizes 11005 and 11004 (AI) air induction extended range flat fan size 11005 (AIXR), preorifice flat fan …
