With the onset of Enlist and XtendFlex technologies, farmers have been regulated to use coarse to very coarse droplet tips. Farmers are also able to harvest more acres in a day’s time allowing them to apply harvest aids over a smaller amount of time. In an attempt to keep up with harvesting ability, it is reasonable to assume farmers may reduce carrier volume rates. This presentation will cover the effects of reducing carrier volume and using coarse spray tips compared to traditional practices of applying harvest aids. This will assist farmers in making decisions about which nozzle tips and water volumes they should use to apply harvest aids and how pressure, water volumes, and tips affect spray patterns.
