Plant Identification -- Submerged Weeds -- Widgeon Grass |
WIDGEON GRASS (Ruppia maritima)
Treatment Tips: Because it can grow in cold water, Widgeon Grass often has a competitive advantage over other aquatics. Treatments should be made as early in the season as possible. Important waterfowl food.
Description: Leaves are thread-like and narrow, extending from anextensive buried root system. Four to six fruits borne in clusters on short stalks at the top of the plants.
Distribution: Commonly found in shallow, brackish water or alkaline waters. Mainly along coastal areas, but scattered into many inland midwestern lakes. Plant is a prime waterfowl food and desirable in some conditions.

Recommended Control Method: For areas less than 1 acre, tank mix 1 part Cutrine-Plus to 5 parts Weedtrine-D. Apply at the rate of 1.2 gallons per 1/5 surface acre.*
OR
For areas in excess of 1 acre, tank mix 1 part Cutrine-Plus to 1 part Reward. Apply at the rate of 2 gallons per surface acre.
**Dilute to facilitate even distribution.
|
Maintenance Control Method: Add Aquashade at the rate of 1 quart per acre-foot of water to prevent initial growth or to retard regrowth of plants after chemical treatment.
|
Alternate Control Methods: Reward: 1.5 gallons per surface acre.
