This plant species rarely becomes problematic.
Non-Herbicide Management Options
1. Physical Management Options
Birdbill dayflower can be cut and removed. However, physical control is difficult because they can re-establish from seeds or remaining roots.
2. Biological Management Options
At this time, there are no biological control methods for Birdbill dayflower.
Herbicide Control Options
Always read the product label for directions and precautions, as the label is the law. Click on the name of the product to see the label. Read the label for specific water use restrictions.
The active ingredients that have been successful in treating Birdbill dayflower include:
- Flumioxazin (E)
- Carfentrazone (E)
- 2, 4-D (G)
1) Flumioxazin
Flumioxazin is a water dispensable granule that is to be sprayed or injected after mixing. It is a broad spectrum, contact herbicide. Contact herbicides act quickly. Flumioxazin should be applied to actively growing plants and a surfactant (a substance that reduces water tension) will be needed if the herbicide is applied to foliage of floating or emergent plants. Water pH needs to be below 8.5 or flumioxazin will rapidly degrade and lose effectiveness.
Common trade and product names include but are not limited to:
2) Carfentrazone
Carfentrazone is a contact herbicide that is absorbed through the leaves. Contact herbicides act quickly and kill all plant cells they come in contact with.
Common trade and product names include but are not limited to:
3) 2,4-D
2,4-D compounds are systemic herbicides. Systemic herbicides are absorbed and move within the plant to the site of action. Systemic herbicides tend to act more slowly than contact herbicides.

Precautions
One danger with any chemical control method is the chance of an oxygen depletion after the treatment caused by the decomposition of the dead plant material. Oxygen depletion can kill fish in the pond. If the pond is heavily infested with weeds, it may be possible (depending on the herbicide chosen) to treat the pond in sections and let each section decompose for about two weeks before treating another section. Aeration, particularly at night, for several days after treatment may help control the oxygen depletion.
One common problem in using aquatic herbicides is determining area and/or volume of the pond or area to be treated. To assist you with these determinations see SRAC #103 Calculating Area and Volume of Ponds and Tanks.
Many aquatically registered herbicides have water use restrictions (See General Water Use Restrictions).

Cultivation Options
Birdbill dayflower can be propagated by planting seeds in moist soil areas with partial shade.
