Propeller is a contact herbicide that acts quickly on aquatic weeds.

Active Ingredient: Flumioxazin 51%

  • Kills the roots of pond weeds
  • Spray on actively growing plants
  • Proper application requires mixing with Plex Mate surfactant to improve leaf penetration

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 Propeller 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.

How to use Propeller Aquatic Herbicide

Mix 2-3 oz of Propeller, 2 oz PlexMate, and 1 gal of water.
