  1. Skunk cabbage: Chemical control using herbicides

    A study in 2010, at Lymington Reedbeds, England, UK (Chatters 2010) found that herbicide sprays, glyphosate and 2, 4-D Amine, each killed skunk cabbage Lysichiton americanus.   Two months following treatment, most plants sprayed with glyphosate appeared to have been killed, whereas most of those sprayed with 2,4-D amine were found to have new shoots.  However, six months following the treatments, a limited survey did not find any skunk cabbage plants, suggesting that both herbicide applications may have been successful.  The site was divided into two sections. A larger downstream section was treated with glyphosate (Roundup Pro Biactive) at a rate of 6 litres/ha. A smaller, upstream section was treated with 2, 4-D Amine in an unspecified amount. Herbicide was applied by two people over a three day time period.  Surveys were conducted for seven to eight weeks, then six months, after application.
