Propeller Aquatic Herbicide Label and Application Instructions

Active Ingredient: Flumioxazin 51%

Flumioxazin is only effective when water PH is below 8.5. If the PH is higher than 8.5, flumioxazin will rapidly degrade and lose effectiveness.

For FASTEST results, Propeller Herbicide may be tank mixed with diquat (Tsunami DQ) for enhanced control of floating and emergent weeds.

Good coverage and contact time is essential. Make applications with sufficient volume of water according to the label. When making applications to floating or emergent weeds, apply at 6 to 12 oz per acre and mix with a surfactant approved for aquatic sites. For subsurface applications apply Propelller at 200 to 400 ppb in the water column. Please see label for information on the effects of high pH on plant response and efficacy.
