Control Frog’s Bit

Manual/Mechanical Control:

Physically cutting Frog’s Bit and digging up the stolons (modified stems that act as roots) can be a somewhat successful way to manage this plant, but physical control can be difficult.

Herbicide Control:

1. Imox and Surfactant (our Cattail and Water Lily Control) –  liquids that you mix together with water in a sprayer. Thoroughly wetting the plants in late summer or early fall is the most practical time to treat. This is when Frog’s Bit plants are directing their energies to the root system, which helps pull the herbicide down to the roots to kill both those and the vegetative portions.
2. Liquid 2, 4-D – liquid that you dilute with water in a sprayer.
3. Dibrox – liquid that you dilute with water in a sprayer, will effectively control Frog’s Bit. Contact herbicide that will kill the plants but not the roots.
4. Semera and Surfactant – granules or liquid that you dilute with water in a sprayer, will give some control. Contact herbicide that will kill the plants but not the roots.
