TANK-MIX PARTNERS
The information provided is meant to be a guide for successful tank-mixing with Helmquat 3SL herbicide.
For successful tank-mixing with Helmquat 3SL, the following order of addition of tank-mix partners should be followed:
Fill spray tank half full with clean water or other approved carriers such as clear liquid fertilizer
Helmquat 3SL should be included in the Liquids (L) portion of WALES method.
Begin tank agitation and continue throughout mixing and spraying
Add dry formulations (WP, DF, etc.) to tank
Add liquid formulations (SC, EC, L, etc.) to tank
Add Helmquat 3SL to tank
Add crop oil concentrate or methylated seed oil to tank where needed
Fill remainder of spray tank
In tank-mixtures, NIS should always be used and added to the tank first. This has proven key to ensure successful tank-mixing in lab testing and field experience with an extensive array of pesticides. If other adjuvants such as crop oil concentrate, methylated seed oil or blends are desired in addition to NIS, then add them to the tank just prior to bringing the mix to full volume as described above.

Products listed have demonstrated compatibility when mixed with Helmquat 3SL under laboratory conditions. Results from field tank-mixes may vary due to water quality, fertilizer quality, order of addition of tank-mix partners, and other variables. Helmquat 3SL may be tank-mixed with products not listed, so long as successful tank-mix experience with previous Gramoxone® brands has been demonstrated.
