On October 3rd, 2018, new regulations around the use of 2-4,D herbicide have changed in Australia.
IMPORTANT: ALWAYS ENSURE TO FOLLOW THE MOST UP TO DATE LABEL FOR YOUR CHEMICAL APPLICATIONS. ALL DELIVERIES OF CHEMICAL MUST BE ACCOMPANIED WITH A CURRENT CHEMICAL APPLICATION LABEL/INSTRUCTIONS, AND SHOULD BE FOLLOWED AT ALL TIMES. Since the time of this posting, information may have changed, so ensure you are following the most recent legislation and chemical label.
Among the changes are specifications to using spray tips that apply at least a very coarse spray quality. Many of the Combo-Jet spray tips are excellent and consistent options for applying under these new label applications, so ensure to reference either the spray tips charts (HERE) or use Tip Wizard, and selection an option that provides a very coarse (specified by a green color coded VMD column).
Combo-Jet drift reduction series spray tips used with PWM spray systems are useable under these new regulations, just ensure you are following the proper spray tip chart, as the tip pressure can change with different PWM systems. Be aware of your systems’ pressure drops and adjust to them as required.
