C.A.N. DO Fact Sheet - Burning Unwanted Crop Residue (Stubble Burning)
"Stubble burning is the practice of burning the residue of a crop
rather than bailing it for livestock use or working it back into the
soil. It has been a part of agricultural practice for many years.
Crop residue refers to the straw, stubble and chaff from any
agricultural crop following harvest. The remains of
unharvested crop can be included."
Stubble: Keep it or burn it?
Pruning Lowbush Blueberry Fields
"Spot Burning: In most fields there will be areas around rocks, at the
edges of the field, in dips, or in excessively bumpy areas that can't
be mowed. These small areas can be burn-pruned with a small portable
flame thrower, a conventional oil burner, or with straw any time prior
to new growth starting in the spring."
Army Surplus on the Farm after World War II - Farming in the 40's
(see image of Flame Thrower Ad)
"Another company advertised a "Modern flame thrower" claiming it
"destroys weeds, tree stumps, splits rocks, disinfects, irrigates, 100
practical uses." All for $22. It is not known whether or not these
were surplus units, but the company undoubtedly benefited from the
fame that flame throwers gained from wartime newsreels, posters and

What about weed control, I believe you have had some experience with
"We have one of the backpack propane flame throwers. It has a 5 inch
wide flame spreader. We used this for carrots and seeded onions. I
think it works fantastically. If you adjust your management to
properly accommodate the benefits of the stale seed bed with the flame
weeding it does wonders."
"There is a romantic idea that the human's use of fire was beneficial
to the bush by regenerating life. The National Museum of Australia
even states that fire activated water in the soil, bringing it to the
surface to quench the thirst of plants. Presumably, the museum's
curators don't water their garden and instead revive their thirsty
plants with a flame thrower."
