Controlling Para grass without herbicides

Para grass, Urochloa mutica, grows in the southeastern United States in fields, marshes and swamps.  It spreads by runners to form dense stands. It can be controlled with herbicides, but managers often wish to avoid using herbicides in sensitive wetland areas.  Research on non-chemical control methods in Florida show that Para grass can be controlled using a combination of flame weeding or mowing and flooding.   Particularly in areas where water levels can be manipulated, burning or cutting plants prior to flooding proved can be an effective means of killing Para grass.
