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:

Imox herbicide and a surfactant will effectively control frog’s bit. These products together are called our Cattail and Water Lily Control. Another product that will control frog’s bit is 2, 4-D. 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.

Semera is a proven effective Frogbit control herbicide.

Dibrox will also effectively control frog’s bit, though it is a contact herbicide and will not kill the roots.
