GENERAL INSTRUCTIONS
Mixing
Add water to the spray tank to 10 cm above the level of agitation and ensure the agitation device is working vigorously. (There must be a minimum of 100 L of water in the tank before any pesticide is added.)
If tank mixing, firstly, add any soluble liquid formulations (e.g. Transit Herbicide) and allow agitation for approximately one minute.
Then add Exert 520 at the point where agitation is strongest. (Do not add Exert 520 through a strainer or sieve). Allow further agitation for one minute.
Half fill the spray tank.
If using wettable powder or water dispersible granules, or other emulsifiable concentration formulations (e.g. LORSBAN™ 750 WG or LE-MAT ), these should be added after the Exert 520 to the half full spray tank ensuring vigorous agitation.
Finally add Supercharge® Spray Tank Adjuvant or approved alternate spraying oil/wetter. (See section on spraying oils/wetters) and continue filling the tank to the required volume maintaining agitation at all times.
Only mix sufficient solution for immediate use. Exert 520 and any other tank mixes should be applied immediately for best results.

Application
Apply Exert 520 Herbicide in sufficient water to obtain good coverage. It should be applied by an accurately calibrated ground rig or aircraft delivering droplets with a VMD of 200-300 microns.
The following spray volumes are recommended.
Ground application 50-150 L/ha
Aerial application 30 L/ha minimum
Use higher water volumes in orchards and in dense crops where the weeds may be shielded by the crop canopy.
