[Paul Cereghino <paul.cereghino@comcast.net>]

In fairly common use in landscape for around 5-10 years (they were novel 
in 1994).  Natural burn has variable frequency and intensity, and 
season, all of which affect how the plant community responds.  The flame 
weeder is conceptually an alternative to spraying, particularly 
appropriate for seedlings or annuals without root reserves.
