In Flame Weeding: What's New?
When the Iowa LP-Gas Assn. agreed to support recent research at Iowa State University on flame weeding, its hope was to put this cultivation technique into the category of a respected and commonly used method of weed control. ISU researchers, discouraged because experiments over several years had revealed no striking progress, proposed that certain new concepts first be devised. The new air-curtain flamer (Fig. 1) is the result.
