Walk-Behind Flame Weeder

Walk-Behind Flame Weeder CROPS Weed Control 19-4-17 Burn off weeds in a garden or small field with this new walk-behind flame weeder. It works on the same principle as tractor-mounted flame weeders that have made a comeback in recent years (see Vol. 16, No. 2 , Vol. 17, No. 2). A propane flame under a metal hood zaps weeds between the rows. The heat ruptures water cells in the plants, killing them in a day or two. Inventor Steve Meyer says kill rate is is more than 90% on annuals, even in heavy infestations, but that it's not as effective on tough perennials like thistle. The "flamer" consists of a 12 in. dia. wheel with four 2 in. dia. propane torches, which create a solid 2 ft. wide flame pattern, mounted just behind. A galvanized metal hood mounts over the torches, which run 1 1/2 to 2 in. off the ground. Rubber hose connects burners with a propane tank carried in a backpack by the operator. Propane flow is controlled with an on/off ball valve on the unit's handle. Burners light manually. One 5-gal. tank will last about an acre, Meyer says. Sells from $225 to $300 not including propane tank and backpack. Contact: FARM SHOW Followup, Eden Valley Institute, 6263 NCR 29, Loveland, Colo. 80538 (ph 303 667-6911).
