The right nozzles can maximize product performance by managing the interaction between application volume, nozzle flow rate, nozzle type, operating pressure, travel speed, nozzle spacing and droplet size category.
“Allowable nozzles and operating pressure (PSI)” details nozzles and pressures that are allowed for use when applying Enlist Duo™ herbicide. Do not use any nozzle and pressure combination not specifically listed on the Enlist Duo herbicide label and in “Allowable nozzles and operating pressure (PSI)”; in case of conflict, the label prevails.
