WATER HYACINTH
(Eichhornia crassipes)
Treatment Tips: Seeds may sink to the bottom and
remain dormant for years. Reinfestation may occur years
after chemical eradication.
Description: Plants are free-floating or rooted
in mud. Leaves are large and broadly lance-like extending
from an inflated stalk. Flowers are blue, violet or white.
Roots are dark and fibrous. Leaf blades may be up to 8
inches (20 cm) long and 2 to 6 inches (5 to 15 cm) wide.
Plant height is variable from a few inches up to 3 feet
tall. Plants reproduce by fragmentation or by seeds.
Distribution:
Common in tropical and subtropical areas of the United States (Florida, Texas and Gulf Coast region). |
Recommended
Control Method: For areas where chemical drift
is a critical concern, tank mix 1 part Cutrine-Plus to
1 part Reward. Apply at the rate of 1 gallon per
surface acre of foliage. Dilute to facilitate even
distribution. Use non-ionic surfactant.
|
| Alternate
Control Methods: Shore-Klear :1-1/3 (1.3) ounces per
gallon of water plus non-ionic surfactant. 75 gallons
of solution will treat 1 acre. |
