Alfalfa Field Flamer

Alfalfa Flaming Kills Weeds, Grasses and Weevil the safe, natural way while increasing yields of weed free hay and saving you money over other methods of weed and weevil control. Heat will kill insect eggs - chemicals will not.  

Also effectively treats field dodder.


Always consult your propane dealer about purchasing the proper tank or have them check your existing tank to make sure it is clean and safe before you begin flaming. You MUST use a propane tank equipped with a Liquid Withdrawal Valve. Do NOT use a bottom withdrawal valve as any possible debris or scale may plug torches or solenoids down the line. We recommend a top-mounted, liquid withdrawal valve with a dip tube which reaches close to, but does not rest on the bottom of the tank. Clean fuel and tank are critical for optimum performance of all flaming equipment. Please check with us before selecting a propane tank.

Red Dragon® Alfalfa Flamers offer producers a single solution for what is usually a two part problem. One flame application replaces insecticide treatment for weevil and replaces herbicide treatment for unwanted weeds and grasses.

Due to the fact that weevil lay eggs all winter, flaming is normally done in late winter or early spring, just before or during greenup. Flaming usually takes between 20 and 30 gallons (76-114 Liters) of propane per acre, depending on the outside temperature when flaming. A second application, if necessary, should be done immediately following the first cutting. This will not hurt the alfalfa but may delay the second cutting by a few days.

Flame Engineering's Patented liquid propane spray process was developed in the 1960's and still works today. By directing the spray at ground level, all plants and insects are subjected to high temperatures thus burning out old growth, making way for new, and eliminating weevils. It takes just a split second to kill weeds, grasses, and insects. Tall stubble will, however, require slower ground speeds and higher pressures.

Red Dragon® Alfalfa Flamers are Safe and Easy to Use. Flamers are designed to skid behind the tank cart (tank and cart are not included) and comes with electronic controls allowing the operator control of the liquid spray from the driver's seat. Each unit flames a 12' swath – to connect two or more, call for advisement on pressures, ground speeds, and capabilities.
