h2. Management Recommendations
Mechanical Controls
Pulling, cutting, or disking. Picking by hand or removing with a pond rake will get rid of small stands. Larger infestations can be controlled with harvesting machines or treated with herbicide.
Herbicidal Controls
Glyphosate in a broadcast foliar treatment 1 to 2 qt product per acre. Larger plants may require higher rates. Spot treatment of 1% solution. Wiper treatment of 33 to 50% of concentrated products. Timing may be post-emergence to seedlings or to mature plants that are growing rapidly
