Knawel Weed Killer

Scleranthus annuus Herbicide

Description of Knawel (Scleranthus annuus):
Knawel is a winter annual which, when it first germinates, may go unnoticed because of its grasslike features. It closely resembles parsley-piert and lawn burrweed. It is a freely branched plant with spreading stems. Leaves, clasping the stem, are opposite, linear, less than 1 mm wide, and sharp-pointed. The very inconspicuous flowers are clustered in the leaf axils. They are small, green, lacking petals, and somewhat spiny to the touch.
