Surfactant: Add Score® surfactant (included in the case) at 8 L per 1000 L of spray solution (0.8% v/v).
Water volume: 40 L/ac (9 imp. gal/ac).
Rainfastness: One (1) hour.
- Always start with a clean and empty sprayer tank.
- Fill the tank 1/2 to 2/3 full of clean water.
- With the agitator running, add the required amount of SG herbicide. Continue to agitate for a minimum of 5 minutes to ensure that the soluble granules (SG) are completely dissolved.
- Make sure there are no undissolved granules, and then add Horizon.
- When adding the tank-mix partner Horizon, an Emulsifiable Concentrate (EC), reduce agitation to avoid inducing an invert emulsion. Once dissolved, the soluble granules will remain in solution.
- Add the rest of the water.
- Add the appropriate amount of Score surfactant. If an anti-foaming agent is required, add last.
- Refer to the tank-mix sections of the Directions for Use booklet for mixing order and other mixing instructions.
- For repeat tank loads, reduce the materials remaining in the tank to 10% of the original volume or less before proceeding with step 1, because remaining chemicals may prevent the SG herbicide from completely dissolving. If this is not possible, pre-slurry the SG herbicide in a small amount (5 L to 10 L) of water before adding to the tank.
Once dissolved, the SG herbicide will not settle out, even if the sprayer is parked for long periods of time. If the sprayer has been left standing for a period of time, agitate thoroughly to re-suspend the Horizon before resuming spraying. Spray preparation should be used within 24 hours or product degradation may occur.
