GENERAL INSTRUCTIONS
MIXING
Measure the required quantity of granules by weighing on scales.
Lontrel 750 SG granules are highly soluble in water and will dissolve rapidly once added to fast moving water.
Maintain agitation at all times, including during mixing as well as spraying.
Spray rigs with premix hoppers
For spray rigs that have a drop down chemical induction hopper, three-quarter fill this hopper with water and have the rinsing sprinkler operating. Add the Lontrel 750 SG and when dissolved, transfer this batch into the quarter filled main tank. Continue to rinse the hopper until the entire product has washed through.
Spray rigs with limited bypass agitation
For spray rigs that have limited bypass agitation, then as for most granulated formulations, pre-dissolve the Lontrel 750 SG in a bucket before adding them to the main tank. Add Lontrel 750 SG while stirring until the granules have dissolved.
Tank-mixes: The following order should be followed:
1. Quarter fill the spray tank maintaining agitation.
2. Add Lontrel 750 SG granules, using the mixing procedure above.
3. Add Verdict 520 if it is to be used in the tank-mix.
4. Add water to half fill the spray tank.
5. Add wettable powders, water dispersible granules or suspension concentrates.
6. Add other emulsifiable concentrates including other selective grass herbicides.
7. If Uptake Spraying Oil is to be used add this when spray tank is half full.
8. If other adjuvants or a wetting agent is to be used than add these according to their label.
9. Add water to bring to the final spray volume.
Only mix sufficient spray solution for immediate use and avoid storing.

APPLICATION
BOOM SPRAYING CROP and PASTURES:
Apply Lontrel 750 SG in sufficient water to obtain good coverage. It should be applied by an accurately calibrated ground rig or aircraft, delivering 200 to 300 micron droplets and not less than 50 L/ha water volume for boom sprayers or not less than 20 L/ha for aerial applications.
Hardhead thistle – Use a spray volume of 200 to 250 L/ha of water.
HIGH VOLUME HAND GUN:
Apply the recommended mix to give full coverage of leaves and stems through a No. 6-8 tip at 700 to 1500 kPa. Spray volume for effective coverage of dense pasture weeds should be 10 to 15 litres of spray per 100 m2 (10 m x 10 m) of infestation. For larger areas an equivalent would be 1000 to 1500 litres per infested hectare.
STEM INJECTION
To make a stem injection pocket at waist height, use a ¾ length axe with a blade width of 5 to 7 cm. The axe cut must be through the bark and deep enough to place all the chemical in contact with the sap wood.
The chemical must be applied immediately after the injection pocket is made. Apply chemical with a Phillips 5 mL vaccinator fitted with a tree injector kit which can be accurately calibrated. Set vaccinator to deliver 1 mL of the diluted mix.
When treating regrowth less than the width of the axe, ensure chemical does not run out the sides of the cut, as reduced control will result. This can be overcome by using the corner of the axe to make the pocket in the stem.

CLEANING SPRAY EQUIPMENT
Rinse water should be discharged onto a designated disposal area or, if this is unavailable, onto unused land away from desirable plants and watercourses.
PARTIAL CLEANING (before spraying crops that are selective to Lontrel 750 SG):
After using Lontrel 750 SG, empty the tank completely and drain the whole system. Thoroughly wash inside the tank using a pressure hose. Quarter fill the tank with clean water and circulate through the pump, line, hoses and nozzles. Drain and repeat procedure twice.
COMPLETE CLEANING (before spraying crops that are susceptible to Lontrel 750 SG residues):
After using Lontrel 750 SG, empty the tank completely and drain the whole system. Thoroughly wash inside the tank using a pressure hose. Quarter fill the tank with clean water and circulate as above, then drain uarter fill the tank again and add an alkali detergent (e.g. Surf, Omo, Drive) at 500 mL/100 L water or 500 g/100 L water and circulate throughout the system for at least fifteen minutes. If using a concentrated laundry detergent use 250 g (or mL)/100 L water. Do not use chlorine based cleaners.
Drain, remove filters and nozzles and clean separately.
Rinse inside the tank thoroughly using a pressure hose and flush system with clean water. Chlorine based cleaners are NOT recommended.
Rinse water should be discharged onto a designated disposal area, or if this is unavailable, onto unused land away from desirable plants and watercourses.

RESISTANT WEEDS WARNING
Lontrel 750 SG Herbicide is a member of the pyridines group of herbicides. The product has the disrupters of plant cell growth mode of action. For weed resistance management, the product is a Group I herbicide. Some naturally occurring weed biotypes resistant to the product and other Group I herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by this product or other Group I herbicides.
Since the occurrence of resistant weeds is difficult to detect prior to use, Dow AgroSciences accepts no liability for any losses that may result from the failure of the product to control resistant weeds.
Strategies to minimise the risk of herbicide resistance are available. Contact your farm chemical supplier, consultant, local Department of Agriculture, or local Dow AgroSciences representative.
