WATERSHIELD (Brasenia schreberi)
Common Name: Dollar bonnet
Treatment Tips: Care must be taken not to wash chemical off leaf surfaces when liquid sprays are used. Treat early before gelatinous coating develops.
Description: Floating leaves that are oval to elliptical with smooth, un-lobed edges. The “stem” (petiole) is attached to the middle of the leaf. Leaves maybe 2 to 5 inches (5 to 10 cm) in length. A slimy, gelatinous coating covers the underside of the leaf and stem particularly on mature plants. A dull, purple flower is produced in early summer. Growth is from a root stock.
Distribution: Usually found in shallow, acid waters throughout the eastern United States, Gulf regions and Pacific coast. |
Recommended Control Method: Apply 150 to 200 pounds of Navigate per surface acre. Distribute granules evenly to assure effective control.
|
Alternate Control Methods: 2,4-D Liquid ester: (see label). Shore-Klear: 3/4 gallon per surface acre (plus non-ionic surfactant).
